CodeIgniter Development in Bristol
Lean, fast CodeIgniter web apps and APIs for Bristol businesses, plus expert support, maintenance, modernisation and rescue of the existing CI3 and CI4 applications you already depend on. Built properly, maintained long-term, delivered by a UK team you actually speak to.
Trusted by:
CodeIgniter is for lean, fast builds and keeping existing apps alive. Here is what that means in practice.
CodeIgniter is a lightweight PHP framework. Its whole appeal is what it leaves out: a tiny footprint, minimal configuration, and a gentle learning curve that lets a focused application be built and deployed quickly. Where a larger framework gives you structure for the kind of complexity you may grow into, CodeIgniter gives you speed and simplicity for the work in front of you right now. For a lean web app, an internal tool, or a focused API, that is often exactly the right trade.
There is a second, equally important reason CodeIgniter matters: an enormous amount of working software runs on it. CodeIgniter has been around since 2006, and across Bristol there are countless business-critical applications built on CodeIgniter 3, and increasingly CodeIgniter 4, that still quietly do their job every day. The developers who built them have frequently moved on. Keeping that software supported, secure, on a current PHP version, and capable of being extended is unglamorous but genuinely valuable work, and it is a large part of what we do. We will be honest with you about when a lean CodeIgniter build is the right call and when a different tool fits better.
Lean web apps, fast turnaround
When the scope is clear and modest, CodeIgniter lets us build and ship quickly without the configuration overhead of a heavier framework. Ideal for focused tools, customer portals, and applications where speed of delivery and simplicity matter more than a sprawling feature set.
Supporting existing CI applications
The work Bristol businesses ask us for most: taking over a CodeIgniter 3 or 4 application whose original developer has gone, and keeping it running. Bug fixes, small features, and a reliable point of contact for the software your operation depends on every day.
Rescuing and stabilising legacy code
An old CodeIgniter app that still works but has had no attention for years is a risk waiting to surface. We stabilise it, get it onto a supported PHP version, and address the most urgent security and reliability issues, so the software you rely on stops being a liability.
Focused REST APIs
CodeIgniter's routing and small footprint make it a sensible choice for lean, fast APIs that serve a mobile app, a front end, or a single integration. When you do not need the full weight of a larger ecosystem, a tight CodeIgniter API does the job efficiently.
Admin tools and dashboards
Internal back-office utilities, reporting dashboards, and operational admin panels where the priority is getting reliable functionality in front of staff quickly. CodeIgniter keeps these practical, fast to build, and easy to maintain.
CI3 to CI4 modernisation
CodeIgniter 4 is a substantial step up from CodeIgniter 3. We plan and carry out migrations in a controlled way, preserving the business logic that often lives only in the old code, so you move to a modern, supported version without a risky big-bang 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. CodeIgniter is our pick for lean, fast builds and for supporting existing CI applications; 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 |
| Small, focused REST API | Workable, heavier | ✓ Best fit | Not suited |
| Complex application with real business logic | ✓ Best fit | Possible | Not suited |
| Heavy background processing and scheduled jobs | ✓ Best fit | Manual effort | Not suited |
| Multi-tenant SaaS application | ✓ Best fit | Possible, more work | Not suited |
| Content-led site with editorial workflow | Possible but heavy | Not suited | ✓ Best fit |
| Quick deployment, minimal configuration, small footprint | More setup | ✓ Best fit | Plugin-dependent |
If you are not sure which applies to your project, describe the problem and we will tell you what we would reach for and why, even if the honest answer is that CodeIgniter is not the right tool for it.
How we approach a CodeIgniter project
Whether we are building something lean from scratch or taking over an application someone else wrote years ago, a CodeIgniter project is only as good as the thinking that goes in first. With legacy work especially, understanding what is already there matters more than rushing to change it. Here is what we pay attention to, and the stages the work actually moves through.
Understanding the real requirement
For new builds, most briefs describe a solution someone has already half-designed; we dig into the underlying problem first. For existing apps, we work out what the software genuinely needs to do before we touch a line of it.
An honest code audit first
When we take over a CodeIgniter application, we audit it before we promise anything. We tell you plainly whether it is sound and just needs support, or whether technical debt is worth addressing, and we never push a rewrite you do not need.
Sound data architecture
The database schema and data model are decisions you live with for years. On new builds we design them deliberately; on existing apps we respect what is there and improve it carefully, because a careless change to a live data model is expensive to undo.
Security and PHP version currency
So much legacy CodeIgniter runs on outdated, unsupported PHP. Getting an application onto a current, supported version and closing off the obvious security exposures is often the single most valuable thing we can do for a business that depends on it.
Maintainable by anyone competent
We keep the codebase readable and conventional, so you are never locked into a single developer. If you ever bring the work in-house or move to another team, the code makes sense to them rather than holding you hostage.
A clear migration path when needed
If the right move is CI3 to CI4, or eventually to Laravel, we map it out honestly: what changes, what risks exist, and how we preserve the business logic that often lives only in the old code. No surprises late in the work.
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 Bristol, London, or anywhere else in the UK, and it works just as well for taking over an existing application as for a new build.
- Discovery, audit and scopingFor new work we get to the bottom of what the application needs to do. For existing apps we audit the codebase, the PHP version, and any technical debt. The output is a clear scope and a fixed-price proposal based on what we actually find, not a placeholder estimate.
- Stabilise or planIf we have inherited an application at risk, we stabilise it first: supported PHP, urgent security fixes, reliable hosting. For a new build, we plan the data model and structure before writing code, keeping things deliberately lean.
- Build or improve in working incrementsWe work against a staging environment you can access throughout, so you see real progress rather than waiting for a single big reveal. Feedback happens while it is still cheap to act on, whether we are adding features or refactoring carefully.
- Testing and quality assuranceThorough testing of the workflows your users actually follow, and automated tests around the logic that matters where it makes sense. We test the awkward edge cases, not just the happy path that always demos well.
- Deployment and go-liveA controlled deployment with a clear plan and sensible rollback, taken with extra care where a live, business-critical application is involved. 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 support arrangement suits you, from occasional changes to a regular development retainer. Keeping CodeIgniter applications supported over the long term is one of the things we do best.
We have built and maintained PHP software since 2008, and run CoreCRM since 2011.
We do not just build applications and walk away. CoreCRM, our own CRM product, has been in continuous production use since 2011 and is maintained to this day. It is direct evidence that we build and support software designed to be depended upon for well over a decade, through multiple framework and language versions. That same discipline, keeping software reliable, secure and maintainable over the long term, is exactly what supporting and modernising a legacy CodeIgniter application demands.
A Kent team trusted with national software work
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 choose the right PHP tool for each job. CodeIgniter is what we reach for when a build needs to be lean and fast, or when a business depends on an existing CodeIgniter application that needs to keep running reliably and securely. The same engineering care we apply to our most demanding bespoke systems goes into keeping those leaner applications dependable year after year.

Working with Bristol businesses
Bristol is one of the strongest economies in the South West and a genuine technology hub, with a deep cluster of software, digital and high-tech engineering firms, a significant aerospace and advanced-engineering presence in and around Filton, and a long-established financial and professional services sector. Add to that a thriving creative, media and animation scene, two large universities feeding a steady supply of technical talent, and a busy harbourside startup community, and you have a city that produces a great deal of practical software: customer portals, internal tools, integrations, reporting systems, and the kind of bespoke applications that off-the-shelf products never quite fit.
A great deal of that software is built on PHP, and plenty of it on CodeIgniter. That is the work CodeIgniter is well suited to, and it is the work we do, whether building something new and lean or supporting and modernising an application a business already relies on. We are not local to Bristol, and we are not going to pretend otherwise: Gravesend is around 170 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 down to Bristol 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 Bristol
Whether you end up working with us, a local Bristol agency, or a freelancer, these are the questions worth asking before you commit. With CodeIgniter, where so much work involves inheriting someone else's code, 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.
Will they take on legacy CI work?
Plenty of developers want only greenfield builds and will quietly steer you toward an unnecessary rewrite. Ask whether they genuinely support and maintain existing CodeIgniter 3 and 4 applications. Inheriting and stabilising other people's code is core to what we do.
Is the framework choice honest?
A developer who recommends one framework for everything is selling, not advising. The right partner will tell you when Laravel or even WordPress is the better fit, and will explain why CodeIgniter is or is not the right tool for your budget and scope.
How do they handle handover?
You should never be locked in by code only one person understands. Ask about documentation, coding standards, and what happens if you want to take the work in-house or to another team. Conventional, readable CodeIgniter is the answer.
What does ongoing support look like?
An application is not finished at launch, and legacy software especially needs steady care. Ask how they keep PHP and CodeIgniter versions current, how they handle security updates, and what a support or retainer arrangement actually costs.
How do they scope and price?
A low headline figure that grows through change requests is not a bargain, and a quote given before auditing legacy code is a guess. Ask how they scope, whether you get a fixed price, and what is and is not included. We scope 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 Bristol: questions answered
The questions Bristol businesses ask us most often about CodeIgniter projects.
Yes. Dev Partners is based in Gravesend, Kent, and we work with businesses across the whole of the UK, including Bristol and the surrounding area. 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 Bristol 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 very small footprint. It is our choice when a project needs to be built quickly and run fast without the weight of a larger framework: lean web apps, focused APIs, internal tools, and dashboards where Laravel would be overkill. It is also the right tool for supporting and modernising the many existing CodeIgniter applications businesses still rely on.
For very complex applications Laravel often fits better, and for content-led sites WordPress usually wins. We will tell you honestly which framework fits your project rather than pushing the one that suits us.
Yes, and it is one of the things Bristol businesses come to us for most. A great deal of working software runs on CodeIgniter 3 and CodeIgniter 4, and the original developers have often moved on. We take over existing CI applications, start with a proper code audit, and give you an honest assessment of the codebase and any technical debt.
From there we support, maintain, extend or modernise it to whatever scope makes sense. We do not insist on a rewrite when the existing application is sound; if it works and just needs steady care, that is what we provide.
That is a very common situation and exactly the kind of work we take on. Many businesses depend on a CodeIgniter 3 application built years ago that still works but has had no attention for a long time, often on an outdated, unsupported PHP version.
We stabilise it first, get it onto a supported PHP version, address the most urgent security and reliability issues, and then plan any modernisation or migration to CodeIgniter 4 in a controlled way. The priority is keeping the software you depend on running safely while we improve it.
Lean web applications and internal tools, focused REST APIs and integrations, admin dashboards and back-office utilities, and quick-turnaround builds where a heavier framework would be unnecessary. Just as often we are supporting, maintaining, modernising or rescuing existing CodeIgniter 3 and CodeIgniter 4 applications.
Bristol has a deep technology, aerospace, financial and professional services, creative and media base, and a lot of that sector runs on exactly the kind of practical PHP software CodeIgniter is well suited to.
It depends on the work. A focused CodeIgniter build or a clearly scoped piece of support starts from a few thousand pounds. Taking over, modernising or migrating a larger legacy application costs more and depends on what the code audit finds.
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. For ongoing support we offer straightforward retainer arrangements.
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. Bristol is around 170 miles from Gravesend; we travel down 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 Bristol clients that means you get a genuinely senior UK team without the cost structure of a large London or regional agency.
It depends entirely on the application and where it is heading. If the app is well-suited to CodeIgniter and you simply need it on a current, supported version, migrating from CI3 to CI4 keeps things lean and familiar. If the application has grown complex, needs heavy background processing, or is becoming a larger platform, moving to Laravel may be the better long-term choice.
We assess the codebase honestly and recommend the path that serves the business, not the one that bills the most hours. Sometimes the right answer is to do neither yet and simply keep the existing application well supported.
CoreCRM is our own CRM product, in continuous production use since 2011 and now built on Laravel. It matters 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 we apply to keeping our own software reliable, secure and maintainable for over a decade is exactly what we bring to supporting and modernising the CodeIgniter applications our clients depend on.
