CodeIgniter is for lean, fast builds and the systems you already depend on.
CodeIgniter is a lightweight PHP framework with a small footprint and very little configuration to fight with. Its value is not in solving the most complex problems imaginable; it is in getting a focused, reliable web application or API built quickly and keeping it simple to run. When a project is well-defined and modest in scope, reaching for a large, heavily structured framework can be more weight than the job needs. CodeIgniter is the right tool when you want to move fast, keep things lean, and avoid paying for machinery you will never use.
There is a second, equally important side to CodeIgniter work today. It has been around long enough that a huge number of business applications were built on it, and many of those systems are still quietly running operations every day. Their original developers have often moved on, the code has not been touched in years, and the business is nervous about changing anything. A great deal of what we do is supporting that software: upgrading CI3 to CI4, fixing security and performance problems, adding the features the business now needs, and rescuing builds that have become risky to touch. For a city like Derby, whose engineering and manufacturing economy runs on practical, long-lived operational software, that ability to look after an existing CodeIgniter system is often worth more than any greenfield build.
Lean web apps, built fast
Focused, well-defined applications that need to be in production quickly. CodeIgniter's small footprint and minimal configuration mean less setup, less ceremony, and a faster route from brief to working software, without committing you to a heavy framework you do not need.
Straightforward APIs and integrations
Clean, dependable REST APIs and integration endpoints that serve a mobile app, a partner system, or another part of your own stack. When the API is well-scoped rather than sprawling, CodeIgniter gets it built and shipped without unnecessary overhead.
Supporting existing CI3 and CI4 systems
The reason many businesses call us. We take over CodeIgniter applications the original developer has left behind, learn the codebase properly, and become the safe pair of hands that keeps it running, patched, and moving forward instead of slowly decaying.
CI3 to CI4 modernisation
CodeIgniter 4 is a significant step forward from CI3, with a cleaner architecture and better long-term support. We plan and carry out migrations carefully, preserving the business logic that often lives only in the old code, so the upgrade is a managed project rather than a gamble.
Rescuing at-risk applications
Code nobody dares change, dependencies long out of date, security holes, and performance that has quietly degraded. We audit honestly, stabilise the system, and give you a clear plan to get it back to a state where it is safe to maintain and build on again.
Internal tools and admin panels
Back-office utilities, admin dashboards, and operational tools that need to be reliable without being heavy. CodeIgniter is well suited to the practical internal software that keeps a business running but does not warrant the scale of a large framework.
Extending what already works
Adding features, reports, and integrations to a CodeIgniter application that is doing its job. We respect what already works, follow the conventions the codebase already uses, and extend it cleanly rather than forcing an unnecessary rewrite.
Laravel vs CodeIgniter vs WordPress
We build in Laravel, CodeIgniter, and WordPress. We are not going to recommend one over the others just to win a project. The right framework depends on the problem, and picking the wrong one is one of the most expensive mistakes a project can make. Here is an honest comparison of when each is the right choice.
| Situation | Laravel | CodeIgniter | WordPress |
|---|---|---|---|
| Lean web app, fast turnaround, modest scope | Can be overkill | ✓ Best fit | Depends on content |
| Supporting or rescuing an existing CodeIgniter app | Not applicable | ✓ Best fit | Not applicable |
| Straightforward API serving an app or partner | Workable, heavier | ✓ Best fit | Not suited |
| Large, complex application with deep business logic | ✓ Best fit | Possible | Not suited |
| Big team on one codebase over many years | ✓ Best fit | Workable | Hard to govern |
| Multi-tenant SaaS with complex access control | ✓ Best fit | Possible | Not suited |
| Content-led site with editorial workflow | Possible but heavy | Not suited | ✓ Best fit |
| Quick internal tool or admin panel | Can be overkill | ✓ Best fit | Awkward fit |
CodeIgniter is the lean, fast choice and the natural home for existing CI work; for genuinely large and complex applications Laravel is usually the better long-term fit, and for content-led sites WordPress. If you are not sure which applies, describe the problem and we will tell you what we would reach for and why, even if the honest answer is that you do not need a framework like CodeIgniter at all.
How we approach a CodeIgniter project
Whether we are building something new and lean or taking over a system someone else wrote years ago, the framework will not save a project that was scoped badly or never understood properly. Here is what we pay attention to, and the stages a CodeIgniter build or rescue actually moves through.
Understanding the real requirement
For new work, most briefs describe a solution someone has already half-designed. We dig into the underlying problem first, because the right lean approach follows from what the business actually needs, not from the first feature list.
An honest code audit first
For existing systems, we read the code before we touch it: how it was built, what version it is on, where the risks and shortcuts are. You get a straight assessment of quality, security and technical debt before any work is committed.
Sound data and structure
The database schema and the way the application is organised are decisions you live with for years. We keep them deliberate and conventional, because retrofitting a tangled structure into a growing application is one of the most expensive corrections in software.
Integrations mapped early
Most operational software has to talk to something else: a finance system, a payment provider, an ecommerce platform, another internal tool. We identify every integration up front so none of them become a nasty surprise late in the work.
Security and updates taken seriously
Inherited CodeIgniter apps often carry outdated dependencies and unpatched holes. Validation, sensible handling of data, and keeping the framework on a supported version are part of the work, not an afterthought once the budget has run out.
Maintainable by anyone competent
We follow CodeIgniter conventions and keep the codebase readable, so you are never locked into a single developer. If you ever bring the work in-house or to another team, the code makes sense to them, the way it should have to us.
From first conversation to long-term support
We run CodeIgniter projects in clear stages so you always know where things stand, what is being decided, and what comes next. Because you deal directly with Rob and Jason rather than an account manager, there is no layer of translation between what you ask for and what gets built. This is the same process whether you are in Derby, London, or anywhere else in the UK, and whether the job is a fresh lean build or taking over a system you already run.
- Discovery, scoping or code auditFor new work we get to the bottom of what the application needs to do, who uses it, and what success looks like. For an existing system we audit the code first and report honestly on its state. Either way the output is a clear scope and a fixed-price proposal based on what we actually find.
- Planning the right approachWe decide the structure, the data model, the integrations, and, for legacy work, whether the right move is to support the current version, upgrade CI3 to CI4, or rebuild. These decisions get made deliberately rather than by accident.
- Build in working incrementsWe develop against a staging environment you can access throughout, so you see real progress rather than waiting for a single big reveal. For rescue work we stabilise first, then improve, so the system stays usable while we work.
- Testing and quality assuranceWe test the logic that matters, plus thorough manual testing of the workflows your users actually follow. We test the awkward edge cases, not just the happy path that always demos well, and we are careful around code we have inherited.
- Deployment and go-liveA controlled deployment to production with a clear plan, sensible rollback, and care taken where an existing system is being replaced or upgraded. Going live should be an event you have rehearsed, not a leap of faith.
- Handover and ongoing supportDocumentation, access, and a straightforward handover, followed by whatever ongoing arrangement suits you, from occasional changes to a regular support retainer. Keeping CodeIgniter applications patched and supported for the long term is core to what we do.
We have run our own PHP software in production since 2011.
CoreCRM, our own CRM product, has been in continuous production use since 2011, built and maintained on Laravel. It is direct evidence that we build and look after PHP software designed to be depended upon for well over a decade, not just for the length of a single project. That same long-term discipline is exactly what supporting an existing CodeIgniter application demands, and it is why businesses trust us to keep their CI3 and CI4 systems alive, patched, and moving forward year after year.
A Kent team trusted with national operational software
Telegraph Media Group, Hearst Communications, CDS Global, AX Paris, Motel Rocks
These are not the typical clients of a regional development agency. They are the kind of businesses that usually work with large London firms. They work with us because the technical depth is there and the overhead is not, and because they get the founders directly rather than a managed account. Distance has never been the issue: most of our work has been delivered remotely for years.
Across that work we build and maintain PHP applications of every size, from lean tools and APIs to complex back-office platforms and long-lived operational systems. The discipline that keeps a national client's software reliable for years is exactly what a CodeIgniter application needs when a business depends on it day in, day out.

Working with Derby and Derbyshire businesses
Derby is one of the country's great engineering and manufacturing cities, home to Rolls-Royce, Toyota and Alstom and a deep supply chain of aerospace, rail and advanced manufacturing firms across Derbyshire. Around that core sits a broad mix of logistics, distribution, professional services and local businesses, many of which run on practical operational software: stock and job systems, customer portals, internal tools, integrations between trading and finance, and bespoke applications that off-the-shelf products never quite fit.
A great deal of that software has been built over the years on lean PHP frameworks like CodeIgniter, and much of it is still in daily use. That is precisely the work we are well placed to take on, whether you need something new built quickly or you have an existing CodeIgniter system that needs a reliable, honest team to support it. We are not local to Derby, and we are not going to pretend otherwise: Gravesend is around 180 miles away. What we offer instead is a genuinely senior UK team, working entirely in-house with no offshore arm, available to you directly rather than through layers of account management.
In practice that distance changes nothing about the quality of the work. Most of our projects, including for national clients, are delivered remotely with regular video calls and a shared staging environment you can see progress on. We come up to Derby for a kick-off workshop or a key milestone when being in the room genuinely helps, and otherwise we keep the overhead, and your costs, sensibly low.
How to choose a CodeIgniter developer in Derby
Whether you end up working with us, a local Derby agency, or a freelancer, these are the questions worth asking before you commit, especially if you are handing over a system you already depend on. The answers tell you a lot about what you are actually buying.
Who actually writes the code?
Some agencies pitch with senior people and deliver via juniors or offshore teams you never meet. Ask directly who will work on your application and who you call when something breaks. At Dev Partners it is the founders and an in-house UK team, with no offshore.
Are they comfortable inheriting code?
Plenty of developers only want greenfield work. Supporting an existing CI3 or CI4 system means reading someone else's code, respecting what works, and improving it safely. Ask whether they take over and maintain legacy CodeIgniter applications, because many will not.
Is the framework choice honest?
A developer who recommends the same tool for everything is selling, not advising. The right partner will tell you when Laravel suits a complex build better, or when WordPress fits a content site, and when CodeIgniter genuinely is the leanest, best fit, and will explain why.
How do they handle CI3 to CI4?
Upgrading is not automatic and the effort depends entirely on how the original code was written. Ask how they assess whether an upgrade is worthwhile, how they plan it, and whether they would ever recommend staying put. Vague enthusiasm here is a warning sign.
What does ongoing support look like?
An application is not finished at launch, and a legacy system needs steady care. Ask how they keep CodeIgniter and its dependencies current, how they handle security updates, and what a support or retainer arrangement actually costs. Vague answers become expensive later.
How do they scope and price?
A low headline figure that grows through change requests is not a bargain. Ask how they scope, whether you get a fixed price, and what is and is not included. We scope carefully, audit existing code first, and quote a fixed price based on what we actually find.
What our clients say
20 clients. A few of their words.
A well-rounded team, ensuring a full suite of expertise & resource is always available. CDS Global have seen the successful completion of major projects over the years where Dev Partners' ability to grasp the underlying business needs to provide a future-proof solution has been invaluable.
We have worked with Jason & his team to develop our Shopify store, and the experience was outstanding from start to finish. The design is clean, modern, and perfectly aligned with our brand identity, while the build is fast, responsive, and easy to manage on the backend. They clearly understood our vision and delivered a store we're genuinely proud of. Highly recommend to any brand looking for a top-quality Shopify partner.
After ongoing issues and delays with our previous developers, we brought in Rob & Jason at Dev Partners to take over all our websites and bespoke software. What a breath of fresh air, fully focused, excellent pre-launch designs and clear communication throughout. Highly recommended.
BPC Energy Ltd turned to Dev Partners for a complete turnkey solution, and they exceeded our expectations. The team handled everything from project management to development and support with real care and attention. They understood what we were aiming for, stayed on top of every detail, and always delivered on schedule with excellent quality.
Working with Dev Partners to redesign and modernise our WMS system: the whole process has been thoroughly professional from the outset and a delight to work with. Cannot recommend enough.
Great agency. Have used Dev Partners for several years and they have built 20+ sites for us, in addition to taking on our legacy websites, upgrading and maintaining. Easy to work with and some great practical ideas to improve our digital offerings.
Jones Hire have been working with Dev Partners on several projects, which have been very successful. They linked our catering database to a new improved website so clients can easily place and update orders, created a custom warehouse picking app to fulfil all our challenging requirements, and are currently developing a custom transport app to streamline our loading and delivery process.
We have been trying to reinvent our website for over 5 years, trying to make it convert and failing each time. Spoke to Rob at Dev Partners, the team helped create our new site and the improvement was instant.
We have been working with Rob and the team for about 10 years now. Dev Partners helped us build a completely bespoke CRM from scratch which manages our daily business and is always well maintained. We have been able to use the system and roll it out in our new franchise branches.
We collaborated with Dev Partners on the front end of a fairly complex telemarketing platform. Rob and Jason took the time to properly understand the moving parts, asked the right questions, and delivered a clean, intuitive interface that's made the system far easier for our team to use.
I have been working with the team at Dev Partners for the last 3 years and we have always been impressed with the speed in which they act on things for us, along with the honest open communication. The team are a valuable and vital part of our supply chain.
We've had a program for our business in the electronic security sector that Dev Partners developed and keep up to date. They've never let us down, always there when needed. Thanks Rob and the team.
Dev Partners have been working with us for just over 2 years. They have significantly upgraded and redesigned our existing web platforms, and always deliver a first class service.
Dev Partners helped us build an event website. The team were very knowledgeable, easy to work with and quick to deliver a high quality product.
Working with Dev Partners has been an exceptional experience. Their team is highly skilled, professional, and committed to delivering results. What truly sets them apart is their communication and transparency; we always felt informed, supported, and confident.
We've worked with Dev Partners a few times to support us on bespoke web build tasks. They're very easy to work with, approachable, and explain the detail in a way that's understandable. A great partner for technical issues at sensible prices.
Excellent customer service backed up with solid experience. As a media business we have had five websites built by Dev Partners. I would certainly recommend them.
Found Dev Partners and they were great, nothing too much trouble. They managed to help us with integrating our old existing system with Shopify.
I've worked with Rob and his team off and on for many years and have always found them to be professional, knowledgeable, and best of all, they listen to their clients and deliver what is required.
We have worked with Dev Partners for 7 years and can highly recommend them for their expertise and excellent customer service.
CodeIgniter development in Derby: questions answered
The questions Derby and Derbyshire businesses ask us most often about CodeIgniter projects, new builds and existing systems alike.
Yes. Dev Partners is based in Gravesend, Kent, and we work with businesses across the whole of the UK, including Derby and the wider Derbyshire region. CodeIgniter development is delivered remotely as standard, and the distance makes no difference to the quality of the work.
You deal directly with the founders, Rob and Jason, throughout the project. We travel to Derby for a kick-off workshop or key milestones when it genuinely adds value, and otherwise keep the overhead low.
CodeIgniter is a lightweight, fast PHP framework with a small footprint and very little configuration. It is an excellent choice for lean web applications and APIs that need to be built quickly, where a heavier framework like Laravel would be overkill.
It is also the framework a great many existing business applications were built on, so a large part of CodeIgniter work today is supporting, maintaining, modernising and rescuing CI3 and CI4 systems that companies still rely on. For very large, complex applications Laravel may be the better long-term fit, and for content-led sites WordPress; we will tell you honestly which suits your project.
Lean internal tools and admin panels, fast APIs and integrations, focused customer-facing web applications, and back-office utilities that need to be reliable without being heavy. Just as importantly, we take on existing CodeIgniter applications that need support: upgrading CI3 to CI4, fixing security and performance problems, adding features to a system the original developer has long since left, and rescuing builds that have become risky to touch.
Derby's manufacturing, engineering, rail and aerospace economy runs on exactly this kind of practical operational software, and much of it has been built on lean PHP frameworks over the years.
Yes, and this is one of the most common reasons businesses come to us. We take over existing CodeIgniter codebases regularly, whether CI3 or CI4. We start with a proper code audit, give you an honest assessment of the quality, security and technical debt, and then work to whatever scope makes sense.
Some inherited applications are sound and just need a steady hand and the occasional change. Others have accumulated problems worth addressing before building further, or are due an upgrade to a supported version. We tell you which one you have before committing to any work.
It depends on the state of the application and how long you need to keep relying on it. CodeIgniter 4 is a significant modernisation over CI3, with a cleaner architecture, namespaces, and better long-term support, but the upgrade is not automatic and the work involved depends on how the original CI3 code was written.
We audit your application first and give you a straight recommendation: sometimes a planned migration to CI4 is the right move, sometimes keeping a well-maintained CI3 application supported is more sensible, and occasionally a rebuild on a different framework makes more sense than an upgrade. We will not push an upgrade you do not need.
It depends on the work. A focused CodeIgniter web app or API, or a defined upgrade or rescue of an existing system, often starts from a few thousand pounds because the framework is lean and fast to work in. Larger applications and complex legacy modernisation cost more. For ongoing support of an existing CodeIgniter system, many clients prefer a retainer.
We scope carefully and give you a fixed-price proposal based on what we actually find, rather than an estimate designed to win the work and adjust later.
Almost all of our project work is delivered remotely, and that has been true for years across our entire client base, including national names. The quality of a CodeIgniter application has nothing to do with where the developer is sitting when they write it.
We run regular video calls, share progress on a staging environment you can access, and stay reachable directly. Derby is around 180 miles from Gravesend; we travel up when a workshop or milestone genuinely benefits from being in the room, and otherwise keep the overhead, and your costs, low.
No. Dev Partners has been a 100% UK in-house team since we were founded in 2008. There is no offshore arm and no subcontracting of the build. The people who scope your project are the people who write the code and the people you can call when something needs attention.
For Derby clients that means you get a genuinely senior UK team without the cost structure of a large London or regional agency.
Yes. We build new lean projects on CodeIgniter 4, the current major version, and we are equally comfortable supporting and maintaining existing CodeIgniter 3 applications that are still in production. We track releases, advise clients on whether and when an upgrade to CI4 is worthwhile, and keep supported applications patched.
Staying on a maintained version matters for security and compatibility, and we make it a managed routine rather than a problem that builds up silently.
CodeIgniter shines when you want something lean and fast: a focused web app, a straightforward API, or an internal tool that does a clear job without the weight and structure of a larger framework. Its small footprint and minimal configuration mean less to learn, less to maintain, and quick turnaround.
Laravel is the better choice when an application is large, complex, will be worked on by a bigger team over many years, or needs the deeper ecosystem around queues, multi-tenancy and complex access control. We build in both and will recommend the one that genuinely fits your project and budget.
CoreCRM is our own CRM product, built on Laravel and in continuous production use since 2011. It is relevant because it is direct evidence that we build and maintain serious PHP software over the long term, not just for the length of a project.
The same discipline that keeps CoreCRM reliable for over a decade is what we bring to maintaining and modernising the CodeIgniter applications our clients depend on, and it is why long-term support of existing systems is something we take seriously rather than treat as an afterthought.
