CodeIgniter Development in Sheffield, South Yorkshire
Lean, fast CodeIgniter web apps and APIs for Sheffield and South Yorkshire businesses, plus expert support, maintenance and rescue for the existing CI3 and CI4 applications you already rely on. Built properly, supported long-term, delivered by a UK team you actually speak to.
Trusted by:
CodeIgniter is for lean, fast builds, and for keeping existing apps alive.
CodeIgniter is a lightweight PHP framework. Its whole appeal is that it is small, fast, and does not get in the way. There is very little to configure, the footprint is tiny, and a competent developer can stand up a working application quickly. That makes it an excellent choice when you need a focused custom tool or a straightforward API built without the weight and ceremony of a larger framework, and when the scope genuinely does not justify reaching for Laravel.
Just as importantly, CodeIgniter has been around for a long time, which means an enormous number of working business applications were built on it and are still running today. A great deal of our CodeIgniter work is therefore not greenfield at all. It is supporting, maintaining, securing, modernising and sometimes rescuing CI3 and CI4 systems that quietly run a business and that the original developer is no longer around to look after. For Sheffield and South Yorkshire, with its long base of manufacturing, engineering and operational businesses, that kind of dependable, long-lived software is exactly where CodeIgniter shows up most.
Lean web apps, built fast
When you need a focused custom application or internal tool and the scope is well defined, CodeIgniter lets us build it quickly and keep it lean. No heavy framework overhead for a problem that does not need it, which usually means lower cost and a faster route to something working.
Rescuing inherited CI apps
An application that runs the business, written by a developer who has long since moved on, suddenly needs a fix or a change and there is nobody to call. We pick up unfamiliar CodeIgniter codebases, work out how they fit together, and stabilise them so you have a maintainable system and a team you can reach.
Support and maintenance of CI3 / CI4
Ongoing support for existing CodeIgniter applications: bug fixes, small enhancements, dependency and security updates, and the steady stream of small changes that keep a working system working. Available ad-hoc or on a regular retainer to suit how often you need us.
Focused REST APIs
Straightforward APIs to serve a mobile app, a front-end, or a third-party integration, where the requirement is clear and modest. CodeIgniter's routing and lightweight controllers make a clean, fast API quick to build and easy to keep maintainable.
CI3 to CI4 upgrades and modernisation
CodeIgniter 4 is a modern rewrite with better structure, namespacing and tooling, and CI3 no longer receives active development. Where it makes sense, we plan and carry out a managed upgrade, or modernise an ageing app in place, so it stays supportable for years rather than drifting out of support.
Operational and internal tools
The unglamorous back-office software that quietly runs a business: stock and job tracking, internal admin panels, reporting tools, and bespoke utilities for how a particular operation actually works. CodeIgniter is a sensible, low-overhead home for tools like these.
Securing legacy applications
Older CodeIgniter apps often carry security debt: outdated PHP, unpatched dependencies, weak input handling. We audit and remediate, closing the gaps that matter most, so a system you depend on is not quietly exposing the business while it carries on working.
A safe pair of hands to take over
Sometimes the need is simply continuity: a dependable UK team to own an existing CodeIgniter application going forward, keep it patched, and be reachable when something needs attention. We are comfortable being that team for the long term.
Laravel vs CodeIgniter vs WordPress
We build in CodeIgniter, Laravel, 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 | CodeIgniter | Laravel | WordPress |
|---|---|---|---|
| Lean web app, fast turnaround, modest scope | ✓ Best fit | Can be overkill | Depends on content |
| Supporting or rescuing an existing CI app | ✓ Best fit | Not applicable | Not applicable |
| Focused REST API, clear requirement | ✓ Best fit | ✓ Strong | Not suited |
| Complex application with heavy business logic | Possible | ✓ Best fit | Not suited |
| Multi-tenant SaaS product | Possible | ✓ Best fit | Not suited |
| Heavy background processing and scheduled jobs | Manual effort | ✓ Best fit | Not suited |
| Content-led site with editorial workflow | Not suited | Possible but heavy | ✓ Best fit |
| Smallest footprint and fewest moving parts | ✓ Best fit | Larger by design | 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 a complex build is better off in Laravel or a content site in WordPress.
How we approach a CodeIgniter project
Whether we are building something lean and new or taking over an application someone else wrote, the framework is only part of the story. A fast build still needs to be the right build, and an inherited app needs to be understood before it is touched. Here is what we pay attention to, and the stages the work 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 build follows from what the business actually needs, not from the first feature list.
Auditing what already exists
For inherited CodeIgniter apps, we start by reading the code, mapping how it fits together, and assessing its quality, security position and technical debt. You get an honest picture of what you are dealing with before any change is made.
Sound data and structure
The database schema and the way the app is organised are decisions you live with for years. We keep new work clean and conventional, and when extending an old app we work with its grain rather than scattering inconsistent patterns through it.
Integrations mapped early
Most operational software has to talk to something else: a finance system, a payment provider, an ecommerce platform, a piece of plant. We identify every integration up front so none of them become a nasty surprise late in the work.
Security and updates taken seriously
Input handling, validation, sensible data handling, current PHP and patched dependencies. On legacy apps this is often where the real risk sits, so we treat closing those gaps as core work, not an afterthought.
Maintainable and documented
We keep the code readable and write down what matters, so you are never locked into a single developer again. If you ever bring the work in-house or move to another team, the application makes sense to them.
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 done. This is the same process whether you are in Sheffield, London, or anywhere else in the UK.
- Discovery, or auditFor new work we get to the bottom of what the application needs to do and who uses it. For an existing app we audit the codebase first, so we know its state, its risks, and what is realistic before anyone commits.
- Scope and fixed-price proposalWe turn that into a clear scope and a fixed-price proposal based on what we actually find, not a placeholder estimate. For ongoing support we agree how it works, whether ad-hoc or a regular retainer.
- Build, or stabiliseWe develop lean CodeIgniter against a staging environment you can access throughout. On inherited apps the early priority is usually stabilising and securing what is there before adding to it.
- Testing and quality assuranceThorough testing of the workflows your users actually follow, plus automated tests around the logic that matters most. We test the awkward edge cases, not just the happy path that always demos well.
- Deployment and go-liveA controlled deployment to production with a clear plan and sensible rollback, with particular care where a live business-critical system is being changed or replaced.
- Handover and ongoing supportDocumentation, access, and a straightforward handover, followed by whatever ongoing arrangement suits you. Keeping CodeIgniter applications patched, supported and reachable for the long term is a large part of what we do.
We have built and maintained our own PHP software since 2011.
CoreCRM, our own CRM product, has been in continuous production use since 2011. It is direct evidence that we build and maintain serious PHP software for well over a decade, through multiple framework versions, not just for the length of a single project. That same long-term discipline, particularly around multi-user access, data integrity and maintainability, is exactly what an existing CodeIgniter application needs from whoever takes it on.
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.
Our work spans the right tool for each job. We reach for CodeIgniter where a lean, fast build fits, or where an existing CodeIgniter system needs a dependable team to support, secure and modernise it. We reach for Laravel on the most demanding bespoke applications, and WordPress where content leads. The constant is a senior UK team that builds software to keep working, and keeps it working.
- Telegraph Media Group: custom operational software built on PHP, maintained and extended over years
- Hearst Communications: bespoke systems development for a global publishing operation
- CDS Global: multi-year PHP development engagement on business-critical operational software
- AX Paris: bespoke back-office connecting Shopify to warehouse and despatch workflows. Case study.
- Motel Rocks: integration middleware connecting Shopify to Oracle NetSuite and 3PL providers. Case study.
Working with Sheffield and South Yorkshire businesses
Sheffield built its name on steel and engineering, and that heritage still shapes its economy: advanced manufacturing, advanced materials, and a strong engineering and metals base sit alongside a growing digital and tech sector, two major universities, and the wider South Yorkshire economy taking in Rotherham, Barnsley and Doncaster. That mix produces a lot of businesses that quietly run on operational software, often bespoke and often years old, where the priority is that it keeps working and stays supported rather than that it was built last week.
That is precisely where CodeIgniter tends to turn up, and precisely the work we do: lean new tools where a heavy framework would be overkill, and dependable support for the existing CI3 and CI4 applications a business already relies on. We are not local to Sheffield, and we are not going to pretend otherwise: Gravesend is around 200 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 Sheffield 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 Sheffield
Whether you end up working with us, a local Sheffield agency, or a freelancer, these are the questions worth asking before you commit. The answers tell you a lot about what you are actually buying, especially if the work is supporting something that already exists.
Will they take on someone else's code?
Plenty of developers only want greenfield work and shy away from inherited apps. If your need is supporting or rescuing an existing CodeIgniter system, ask directly whether they are comfortable picking up an unfamiliar codebase. We do it regularly and start with a proper audit.
Who actually writes the code?
Some agencies pitch with senior people and deliver via juniors or offshore teams you never meet. Ask who will write or maintain 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.
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 CodeIgniter is genuinely the lean, sensible fit, and when a complex build really belongs in Laravel or a content site in WordPress.
Do they understand CI3 vs CI4?
The two versions are very different, and CI3 no longer receives active development. Ask whether they can support your version, and whether and when an upgrade to CI4 makes sense for your situation rather than as a default revenue grab.
What does ongoing support look like?
An application is not finished at launch, and a legacy one needs steady care. Ask how they handle security and dependency updates, how responsive support is, and what an ad-hoc or retainer arrangement actually costs. Vague answers here 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 first where there is existing code, 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 Sheffield: questions answered
The questions Sheffield and South Yorkshire 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 Sheffield and the wider South Yorkshire 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 Sheffield 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. It is our choice when a project needs to be built quickly and stay lean: focused web apps, internal tools, and straightforward APIs where a heavier framework like Laravel would be overkill.
It is also the framework behind a great many existing business applications, so a large part of our CodeIgniter work is supporting, maintaining, modernising and rescuing CI3 and CI4 systems that companies still depend on. For genuinely complex applications Laravel may suit better, and for content-led sites WordPress; we will tell you honestly which fits.
Lean custom web applications and internal tools, focused REST APIs, and fast turnaround builds where a modest, well-defined scope does not justify a heavier framework. Just as often we take over existing CodeIgniter applications: CI3 and CI4 systems that need bug fixing, securing, extending, upgrading, or rescuing after the original developer has moved on.
Sheffield and South Yorkshire have a strong manufacturing, engineering, advanced materials and digital base, and a lot of that sector runs on exactly this kind of operational software.
Yes, and it is one of the things we do most. We take over existing CodeIgniter codebases regularly, including older CI3 applications that are no longer actively maintained. We start with a proper code audit, give you an honest assessment of the quality, the security position and any technical debt, and then work to whatever scope makes sense.
Some inherited applications are sound and just need extending or securing. Others need more substantial modernisation, and in some cases a managed upgrade from CI3 to CI4 or a planned migration. We tell you which one you have before committing to any work.
Yes. This is one of the most common reasons businesses come to us. An application that has quietly run the business for years, written by a developer or agency who is no longer contactable, suddenly needs a change, a fix, or a security patch and there is nobody to call.
We are comfortable picking up unfamiliar CodeIgniter codebases, working out how they fit together, documenting what we find, and stabilising them so you have a maintainable system and a UK team you can actually reach again.
It depends on the work. Because CodeIgniter is lean and fast to build in, a focused new app or API can be one of the more cost-effective ways to get a custom tool built. Support and maintenance of an existing CI application can be arranged as occasional ad-hoc work or a regular retainer, and a larger modernisation or CI3-to-CI4 upgrade is scoped on what the audit finds.
We give you a fixed-price proposal based on what we actually find in your requirements, not 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. Sheffield is around 200 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 Sheffield clients that means you get a genuinely senior UK team without the cost structure of a large London or regional agency.
It depends on the application and how long you expect to rely on it. CodeIgniter 4 is a modern rewrite with better structure, namespacing and tooling, and CI3 no longer receives active development. If your CI3 app is stable and short-lived, securing and maintaining it in place may be the sensible choice.
If you expect to keep extending it for years, a planned upgrade to CI4, or in some cases a migration to a different framework, is usually the better long-term investment. We will assess your specific codebase and give you a straight recommendation rather than pushing the bigger job.
Sometimes. CodeIgniter is excellent for lean, fast builds and for supporting the large number of existing CI applications already in use. For genuinely complex applications with heavy business logic, large teams, extensive background processing or multi-tenant SaaS requirements, Laravel's larger structure and ecosystem usually pays off.
We build in both, plus WordPress for content-led sites, and we will tell you honestly which fits your problem rather than defaulting to whichever is easiest for us to sell.
CoreCRM is our own CRM product, built and in continuous production use since 2011. 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 discipline that keeps our own software reliable for over a decade, particularly around multi-user access, data integrity and long-term maintainability, is the same discipline we bring to maintaining and modernising your CodeIgniter application.
