CodeIgniter Development in Liverpool, Merseyside
Lean, fast CodeIgniter web applications and APIs for Liverpool and Merseyside businesses, plus expert support, maintenance and rescue of existing CI3 and CI4 systems. Built properly, kept running long-term, delivered by a UK team you actually speak to.
Trusted by:
CodeIgniter is for lean, fast builds, and for keeping established apps alive.
CodeIgniter is a lightweight PHP framework with a deliberately small footprint and a shallow learning curve. That sounds modest, and that is exactly the point. Where a larger framework brings structure, conventions and a great deal of machinery, CodeIgniter brings speed and directness. For a focused application or an API that needs to be built quickly and run fast, that leanness is a genuine advantage rather than a limitation. You are not paying, in build time or in runtime weight, for features the project does not need.
There is a second, equally important reason CodeIgniter matters. It has been one of the most widely used PHP frameworks for well over a decade, which means an enormous number of working business applications were built on it, many on CodeIgniter 3. Those systems are still doing real work for real companies across Merseyside and the rest of the UK, and they deserve proper support rather than being abandoned because a framework is no longer the fashionable choice. A great deal of our CodeIgniter work is exactly that: keeping established CI3 and CI4 applications secure, reliable and maintainable, extending them sensibly, and migrating them when, and only when, it genuinely pays to.
Lean web apps, built fast
When the scope is focused and the timeline matters, CodeIgniter lets us build a clean, working application quickly without dragging in machinery the project will never use. Ideal for internal tools, customer portals, and practical line-of-business apps where speed and simplicity win.
Rescuing and supporting legacy CI apps
This is core to what we do. Inherited CodeIgniter 3 or 4 application that the original developer has left behind? We audit it, secure it, stabilise it, and keep it running. A working system that earns its keep is worth supporting, not scrapping on principle.
APIs and integrations
CodeIgniter is a sound choice for straightforward REST APIs and integration endpoints that connect systems together without ceremony. Fast to stand up, light to run, and easy to keep maintained when the next integration comes along.
CI3 to CI4 modernisation
CodeIgniter 4 is a significant rework of the framework. Where an upgrade genuinely pays off, we plan and run the migration carefully, preserving the business logic that often lives only in the old code, rather than treating it as a simple version bump.
Back-office tools and dashboards
Admin panels, internal dashboards, reporting tools and operational utilities where a fast, no-nonsense build does the job. CodeIgniter's directness keeps these practical and affordable without skimping on access control or data integrity.
Performance and security hardening
Existing CodeIgniter app feeling slow, or you are unsure whether it is secure? We profile the bottlenecks, tighten input handling and access control, update dependencies, and bring an ageing application back to a state you can rely on.
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 shines for lean, fast builds and for supporting the large installed base of existing CodeIgniter 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 |
| Straightforward REST API or integration endpoint | Workable, heavier | ✓ Best fit | Not suited |
| Large, complex application with deep business logic | ✓ Best fit | Possible, less structure | Not suited |
| Heavy background processing and scheduled jobs | ✓ Best fit | Manual effort | Not suited |
| Multi-tenant SaaS application | ✓ Best fit | Possible | Not suited |
| Content-led site with editorial workflow | Possible but heavy | Not suited | ✓ Best fit |
| Smallest footprint and fastest raw runtime | Heavier by design | ✓ 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 a complex build is better in Laravel or a content site is better in WordPress.
How we approach a CodeIgniter project
Whether we are building something new and lean or taking over an application someone else wrote years ago, the discipline is the same. The framework's speed will not save a project that was scoped badly or a legacy app that is never properly understood before it is changed. Here is what we pay attention to, and the stages the work actually moves through.
Understanding the real requirement
For a new build, we dig into the underlying problem before reaching for code, because the leanest solution comes from knowing exactly what the business needs and, just as usefully, what it does not.
A proper audit of existing code
For an inherited CodeIgniter app, we start by reading it carefully: structure, security posture, dependencies, and where the real business logic lives. You get an honest picture before anyone changes a line.
Sound data handling
The database and how the application reads and writes it are decisions you live with for years. We keep queries safe and sensible, because retrofitting a bad data layer into a growing application is expensive and risky.
Security taken seriously
Input validation, query safety, session and access handling, and sensible treatment of data are part of the work from the start, not a hardening pass bolted on at the end. Older CI3 apps especially benefit from a careful security review.
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 pass it to another team, the code makes sense to them.
Honest upgrade decisions
We only recommend a CI3 to CI4 migration, or a rebuild, when the cost genuinely buys you something. A stable application doing its job may be better simply kept supported and secure than upgraded for the sake of it.
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 Liverpool, London, or anywhere else in the UK, and whether the work is a fresh build or rescuing something that already exists.
- Discovery, or auditFor 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 codebase first, assessing quality, security and technical debt. Either way the output is a clear scope and a fixed-price proposal based on what we actually find.
- Planning and approachWe decide the lean route through the work: what to build, what to leave out, and, for legacy systems, what to keep, what to fix, and whether an upgrade is worth it. The decisions that determine maintainability get made deliberately rather than by accident.
- Build, or stabilise, in incrementsWe work against a staging environment you can access throughout, so you see real progress rather than waiting for a single big reveal. New features and fixes land in working increments, and feedback happens while it is still cheap to act on.
- Testing and quality assuranceWe test the workflows your users actually follow, plus the awkward edge cases that legacy applications love to hide. For inherited code, we verify that changes do not quietly break behaviour the business has come to rely on.
- Deployment and go-liveA controlled deployment to production with a clear plan and sensible rollback, taking particular care where a live system thousands of people depend on is being changed. 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. We keep CodeIgniter applications secure and supported for the long term.
We have maintained PHP software in production for over a decade.
We do not just build applications and walk away. CoreCRM, our own CRM product, has been in continuous production use since 2011, and we have supported and extended client PHP systems, CodeIgniter among them, for years. That track record is exactly what you want from a partner taking over a business-critical CodeIgniter application: the discipline to keep software reliable and secure long after the initial build, not just for the length of a single project.
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. Where a build needs to be lean and fast, or where an established CodeIgniter application needs supporting and modernising, CodeIgniter is what we reach for. Where an application is large and complex, we build in Laravel. The point is always to fit the framework to the problem rather than the other way around.
- 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 ERP-style back-office connecting Shopify to warehouse and despatch workflows. Case study.
- Motel Rocks: PHP-based integration middleware connecting Shopify to Oracle NetSuite and 3PL providers. Case study.
Working with Liverpool and Merseyside businesses
Liverpool has reinvented itself into one of the most dynamic city economies in the North West, with a strong digital and creative cluster, a major university and student population, a busy visitor and events economy, and a maritime and logistics heritage that still runs through the Port of Liverpool and the wider Merseyside supply chain. That mix produces a lot of practical, line-of-business software: booking and portal systems, internal tools, integrations between trading, logistics and finance, and the kind of focused applications that off-the-shelf products never quite fit.
It also means a lot of established PHP applications, plenty of them built on CodeIgniter over the last decade, are quietly doing important work and need keeping reliable. That is exactly the kind of engagement we are built for, whether it is a lean new build or supporting and modernising something that already exists. We are not local to Liverpool, and we are not going to pretend otherwise: Gravesend is around 260 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 Liverpool 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 Liverpool
Whether you end up working with us, a local Liverpool agency, or a freelancer, these are the questions worth asking before you commit, especially if you are handing over an application you 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 happy with legacy code?
Plenty of developers only want greenfield projects. Supporting an inherited CI3 application that someone else wrote is a different skill. Ask whether they take on existing codebases, how they audit them, and whether they can keep an older app running rather than insisting on a rebuild.
Is the framework advice honest?
A developer who pushes the same framework for everything is selling, not advising. The right partner will tell you when CodeIgniter is the lean, sensible fit, when a complex build belongs in Laravel, and when a content site is better in WordPress, and will explain why.
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?
A CodeIgniter app is not finished at launch, and a legacy one needs steady care. Ask how they handle security updates, how they keep dependencies current, and what a support 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, start legacy work with a fixed-price audit, and quote based on what we actually find.
What our clients say

CodeIgniter development in Liverpool: questions answered
The questions Liverpool and Merseyside 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 Liverpool and the wider Merseyside 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 Liverpool 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 an excellent choice when you need a lean web application or API built quickly, with a small footprint and a shallow learning curve, where a heavier framework like Laravel would be overkill.
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 that businesses still rely on. For very large, complex applications Laravel may suit better, and for content-led sites WordPress; we will tell you honestly which fits.
Lean web applications and internal tools, REST APIs and integrations, customer portals and booking systems, and focused back-office utilities where a fast, no-nonsense build matters. Just as importantly, we take on existing CodeIgniter applications that need supporting, extending, securing or rescuing, whether they are on CI3 or CI4.
Liverpool has a strong digital, maritime, logistics, retail and visitor economy, and a lot of that sector runs on exactly the kind of practical PHP software CodeIgniter was built for.
Yes, and this is a large part of what we do. We take over inherited CodeIgniter codebases regularly, including older CI3 applications where the original developer has long since moved on. We start with a proper code audit, give you an honest assessment of the quality, the security posture and any technical debt, and then work to whatever scope makes sense.
Some applications just need ongoing support and small changes. Others benefit from an upgrade path to CI4 or a careful modernisation. We tell you which one you have before committing to any work.
Sometimes, but not always, and not just because a newer version exists. CodeIgniter 4 is a significant rework with a different structure, so an upgrade is a real piece of work rather than a flip of a switch.
If your CI3 application is stable, doing its job, and you simply need it kept secure and occasionally changed, ongoing support may be the sensible answer. If you are investing heavily in new features, or the application is becoming hard to maintain, a planned migration to CI4 can be worthwhile. We give you a straight assessment of cost versus benefit rather than pushing an upgrade for its own sake.
It depends on the work. A focused CodeIgniter application or API can be genuinely cost-effective precisely because the framework is lean and fast to build with. Taking over and stabilising an existing application starts with a fixed-price audit so you know exactly what you are dealing with. A full migration or rebuild costs more.
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. Liverpool is around 260 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 Liverpool clients that means you get a genuinely senior UK team without the cost structure of a large London or regional agency.
For the right job, yes. CodeIgniter 4 is actively maintained and remains one of the fastest, lightest PHP frameworks available, which makes it a sound choice for lean applications and APIs that do not need the weight of a larger framework.
Just as importantly, there is an enormous installed base of working CodeIgniter applications that businesses depend on, and those deserve proper support rather than being abandoned because a framework is no longer fashionable. We are equally happy building something new in CI4 or keeping a mature CI3 system running reliably.
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 we apply to our own product, around data integrity, multi-user access and long-term maintainability, is what we bring to CodeIgniter work, whether we are building lean and fast in CI4 or keeping an established CI3 application reliable for years to come.
