CodeIgniter is for lean, fast builds. And for keeping what you already run alive.
CodeIgniter is a lightweight PHP framework. Where heavier frameworks give you a vast toolbox and a steep learning curve, CodeIgniter gives you a small, fast, well-understood foundation that gets a working application up quickly. That is its strength: when the job is a focused web app, an internal tool, or a straightforward API, CodeIgniter lets us build it cleanly and ship it without the overhead a bigger framework would impose. For a lot of practical business software, that is exactly the right trade-off.
There is a second reason CodeIgniter matters, and for many Reading businesses it is the more important one. CodeIgniter has been one of the most widely used PHP frameworks for well over a decade, which means an enormous number of business-critical applications were built on it and are still running today. Those systems still process orders, manage members, run portals and quietly hold a business together. When the original developer has moved on and the code feels like a risk, that application does not need throwing away. It needs someone who understands CodeIgniter, including older CI3 codebases, to support it, secure it, and modernise or migrate it to CI4 when the time is right. That is a great deal of what we do.
Supporting and rescuing legacy CI apps
You have a CodeIgniter application the business depends on, and the person who built it has gone. We take it on: audit it, stabilise it, fix what is broken, close security gaps, and become the reliable team you can call. This is one of the most valuable things we do, and one of the most common.
CI3 to CI4 modernisation
CodeIgniter 4 is a substantial rewrite, so moving from CI3 is a proper migration, not a switch you flip. We plan it carefully, preserve the business logic that often lives only in the old code, and bring the application onto a supported, maintainable footing with as little disruption as possible.
Lean web apps, fast turnaround
When the scope is focused and the timeline is tight, CodeIgniter's small footprint and low ceremony let us deliver a clean, working application quickly. No waiting on a heavyweight framework to justify itself on a job that simply does not need it.
Straightforward APIs and integrations
For a focused REST API or a service that connects two systems together, CodeIgniter does the job without imposing a large surface area. Predictable, quick to stand up, and easy for the next developer to read and extend.
Internal tools and line-of-business apps
The admin screens, workflow tools, and small operational apps that make a team's day run. CodeIgniter is well suited to practical software that needs to work reliably without becoming a project in its own right to maintain.
Customer portals and account areas
Login areas, customer self-service, booking and account portals where a clean, fast, secure PHP application is exactly what is needed. We build these to be readable and maintainable so they do not become tomorrow's legacy headache.
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 the many businesses still running on existing CodeIgniter systems. 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 or simple integration | Workable, heavier | ✓ Good fit | Not suited |
| Complex application with deep business logic | ✓ Best fit | Possible, less ideal | Not suited |
| Content-led site with editorial workflow | Possible but heavy | Not suited | ✓ Best fit |
| Small, predictable footprint and low overhead | Larger by design | ✓ Best fit | Plugin-dependent |
| Multi-tenant SaaS at scale | ✓ Best fit | Possible, less ideal | Not suited |
| Heavy background processing and scheduled jobs | ✓ Best fit | Manual effort | Not suited |
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 your build would be better served by Laravel or that an existing CodeIgniter app is best left where it is and simply kept supported.
How we approach a CodeIgniter project
Whether we are building something lean from scratch or taking on an application someone else wrote years ago, the framework will not save a project that was scoped badly or never tested properly. Here is what we pay attention to, and the stages a CodeIgniter engagement actually moves through, including the audit step that matters so much when you are inheriting code.
Audit before anything else
For an existing CodeIgniter app, we start with a proper code and security audit. You get an honest picture of what you have, what version you are on, where the risks and technical debt sit, and what is genuinely worth doing, before any quote is committed.
Understanding the real requirement
Most briefs describe a solution someone has already half-designed. We dig into the underlying problem first, because the right approach, lean new build or careful intervention in an existing system, follows from what the business actually needs.
Sound, simple data architecture
The database schema is a decision you live with for years. We design it deliberately on new builds, and on legacy work we map what already exists so changes are made with full understanding rather than guesswork.
Security and updates taken seriously
Older CodeIgniter apps often carry quiet security debt: outdated dependencies, weak input handling, unpatched framework versions. We treat input validation, authentication and patching as core work, not an afterthought bolted on at the end.
Maintainable by anyone competent
We follow CodeIgniter conventions and keep the codebase clean and readable, so you are never locked into a single developer. If you bring the work in-house later or to another team, the code makes sense to them.
Tested, not just demoed
We test the workflows your users actually follow, including the awkward edge cases, so that changes do not quietly break things that already worked. On legacy systems that discipline is what makes a takeover safe rather than risky.
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 Reading, London, or anywhere else in the UK, and whether we are building new or rescuing something existing.
- Discovery, audit and scopingFor a new build we get to the bottom of what the application needs to do and who uses it. For an existing app we audit the code, version and security first. Either way the output is a clear scope and a fixed-price proposal based on what we actually find, not a placeholder estimate.
- Planning and architectureWe agree the approach before building: the structure and data model for a new app, or the migration and modernisation plan for an existing one, including whether a CI3 to CI4 move is worthwhile now or later.
- Build or modernise 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. On legacy work we change things carefully, in small safe steps, with the old behaviour preserved where it matters.
- Testing and quality assuranceThorough testing of the workflows your users actually follow, plus the awkward edge cases that never demo well. On a takeover this is where we confirm nothing that worked before has quietly stopped working.
- Deployment and go-liveA controlled deployment to production with a clear plan and sensible rollback, taking particular care where an existing system is being replaced or upgraded in place. Going live should be a rehearsed event, 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. For inherited apps this is often the whole point: a reliable team you can call.
We build PHP software designed to be maintained for over a decade.
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 the long term, not just for the length of a single project. That same discipline, around data integrity, security and long-term maintainability, is exactly what we bring to supporting and modernising the CodeIgniter applications businesses depend on every day.
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 the job. CodeIgniter is what we reach for when a lean, fast application or a focused integration is the right answer, and it is also the framework behind a great many established systems we have been trusted to support, secure and modernise rather than rebuild from scratch.

- Hearst Communications: bespoke systems development for a global publishing operation
- CDS Global: multi-year development engagement on business-critical operational software

- Motel Rocks: integration middleware connecting Shopify to Oracle NetSuite and 3PL providers. Case study.
Working with Reading and Berkshire businesses
Reading sits at the heart of the Thames Valley, one of the densest technology and professional-services economies in the UK. The town and the wider Berkshire corridor along the M4 are home to a deep cluster of software, telecoms, IT services and corporate head offices, alongside finance, insurance and a substantial professional-services base. That mix produces exactly the kind of businesses that run on practical web applications: internal tools, customer portals, booking and workflow systems, APIs between platforms, and a long tail of bespoke software that off-the-shelf products never quite fit.
A lot of that software was built on CodeIgniter over the last fifteen years, which is why so much of the value we add in a tech-heavy region like the Thames Valley is in supporting, securing and modernising systems that are still doing real work. We are not local to Reading, and we are not going to pretend otherwise: Gravesend is on the other side of London. 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. Reading is a comfortable run round the M25 and along the M4, so we come over 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 Reading
Whether you end up working with us, a local Reading agency, or a freelancer, these are the questions worth asking before you commit, especially if you are handing over an application someone else built. 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 with legacy CI3?
Plenty of developers only want greenfield work. If your application runs on an older CodeIgniter version, you need someone who will happily get into a CI3 codebase, understand it, and improve it. Inheriting and rescuing existing CodeIgniter apps is core work for us, not an inconvenience.
Is the framework choice honest?
A developer who recommends CodeIgniter for everything, or who wants to rewrite a perfectly good app just to use something newer, is selling, not advising. The right partner will tell you when Laravel suits a complex build better, or when your existing system is best kept and simply supported.
Do they audit before they quote?
For a takeover, anyone who quotes a number before looking properly at the code is guessing. Insist on a code and security audit first, so the scope and price reflect the real state of the application rather than an optimistic assumption that grows later.
What does ongoing support look like?
For most legacy CodeIgniter apps, reliable ongoing support is the real need. Ask how they handle security patching, framework updates, and a support or retainer arrangement, and what it actually costs. Vague answers here become expensive later.
How do they handle handover?
You should never be locked in by code only one person understands, least of all on a system you already inherited once. Ask about documentation, conventions, and what happens if you want to take the work in-house. Conventional, readable CodeIgniter is the answer.

CodeIgniter development in Reading: questions answered
The questions Reading and Berkshire businesses ask us most often about CodeIgniter projects, new builds and legacy support alike.
Yes. Dev Partners is based in Gravesend, Kent, and we work with businesses across the whole of the UK, including Reading and the wider Berkshire 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. Reading is a straightforward run round the M25 and along the M4, so we travel over 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 a clean, working web application or API built quickly and without the weight of a larger framework: lean internal tools, focused public-facing apps, straightforward APIs, and projects where a small, predictable footprint matters.
It is also the framework behind a huge number of business applications built over the last fifteen years, so a great deal of our CodeIgniter work is supporting, maintaining and modernising existing CI3 and CI4 systems. For genuinely complex applications Laravel is often the better fit, and for content-led sites WordPress usually wins. We will tell you honestly which fits your project.
Lean web applications and internal tools, straightforward REST APIs, customer portals and account areas, booking and workflow systems, and focused line-of-business apps where speed of delivery matters. Just as often we are taking on existing CodeIgniter applications a business still relies on: extending them, fixing them, securing them, and modernising or migrating them from CI3 to CI4.
Reading has a deep technology and professional-services economy, and a lot of that sector runs on exactly the kind of practical PHP application CodeIgniter was built for.
Yes, and this is a large part of what we do. We regularly inherit CodeIgniter applications, including older CI3 systems, where the original developer has moved on. We start with a proper code audit and an honest assessment of the quality, security, and technical debt, then work to whatever scope makes sense.
Some inherited applications are sound and just need extending or upgrading. Others have accumulated problems worth addressing before building further. Either way you get a clear picture before committing to any work, rather than a quote that grows once we are in.
Often, but not always, and the honest answer depends on the application. CodeIgniter 4 is a significant rewrite, so an upgrade is a migration project rather than a flip of a switch. If your CI3 app is stable, secure, and meeting the business need, the priority may simply be keeping it patched and supported.
If you are actively investing in it, or it is becoming hard to maintain, migrating to CI4 is usually worthwhile and pays back in maintainability and longevity. We audit the application first and give you a straight recommendation, including the option of leaving it on CI3 where that is genuinely the sensible call.
It depends on the scope. A focused CodeIgniter app or API, which is exactly the kind of lean build CodeIgniter is good for, starts from a few thousand pounds. Taking over and modernising an existing system is scoped after an audit so the figure reflects the real state of the code rather than a guess.
Ongoing support and maintenance can be arranged ad hoc or on 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. Reading is well under two hours from Gravesend via the M25 and M4; we travel over 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 Reading clients that means you get a genuinely senior UK team without the cost structure of a large London or Thames Valley agency.
For the right kind of project, yes. CodeIgniter 4 is actively maintained, fast, and well suited to lean applications and APIs where a smaller, more predictable framework is an advantage rather than a limitation. It is also the reality that a great many production business systems were built on CodeIgniter and still run on it, so keeping those applications healthy, secure and supported is genuinely valuable work.
We are honest about its limits: for very complex domains Laravel is usually the stronger long-term choice, and we build in both, so the recommendation is based on your project rather than on what we happen to prefer.
CoreCRM is our own CRM product, built on Laravel and in continuous production use since 2011. It is relevant even to a CodeIgniter enquiry 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, around data integrity, multi-user access, and long-term maintainability, is what we apply when we support and modernise the CodeIgniter applications businesses depend on every day.
