CodeIgniter Development
CodeIgniter Development, Upgrades & Migration to Laravel
New features, bug fixes and PHP 8 upgrades for CodeIgniter 3 and 4 applications — and a planned move to Laravel when the time is right.
Keep the Application Working, Then Make It Better
Thousands of business applications still run on CodeIgniter, and many of them work perfectly well. The trouble starts when the developer who built it has moved on, the server needs PHP 8, or a new feature has to be added to code nobody has touched in years.
We take on CodeIgniter 2, 3 and 4 applications as they are. We read the code before we quote, fix what is broken, add what you need, and bring the application onto a supported PHP version. When it makes sense we plan a gradual migration to Laravel, module by module, so the business never has to stop for a rewrite.
What’s Included
What We Do With CodeIgniter Applications
Bug Fixes & Error Resolution
Fatal errors, broken forms, database errors and pages that stopped working after a hosting change — diagnosed from logs and fixed at the source.
PHP 8 & CodeIgniter 4 Upgrades
Deprecated functions, removed extensions and changed behaviour handled so the application runs on a current, supported stack.
New Features & Integrations
Extra modules, reports, payment gateways, SMS and email services, or third-party APIs added within the existing structure.
Security Hardening
SQL injection, XSS and CSRF gaps closed, password hashing modernised, file uploads locked down and dependencies updated.
Performance Tuning
Slow queries, missing indexes, N+1 loops and uncached views found and fixed; response times measured before and after.
Migration to Laravel
A staged move to Laravel that keeps your database and users, replacing modules one at a time behind the same URLs.

FAQ
CodeIgniter Development FAQs
Our CodeIgniter app stopped working after the host upgraded PHP. Can you fix it?
Yes — this is the most common reason we are called. PHP 8 removed functions and changed how errors are raised, which breaks older CodeIgniter code. We fix the incompatibilities so the application runs on the new version rather than asking the host to roll back.
Should we upgrade CodeIgniter or move to Laravel?
If the application is stable and mainly needs maintenance, upgrading to CodeIgniter 4 on PHP 8 is the cheaper, lower-risk path. If you have a roadmap of new features, Laravel gives you a much larger ecosystem and easier hiring. We will tell you honestly which fits after reviewing the code.
Can you work without the original developer?
Yes. Most of the CodeIgniter applications we maintain came to us without documentation or a handover. We map the application first, then work from that map.
Will a migration to Laravel mean downtime?
No. We migrate in stages behind the same URLs, keep the same database, and switch each module over once it is tested. Users see the application keep working while it changes underneath.

Plenty of business applications still run on CodeIgniter, and most of them are fine. Here is how to decide whether yours needs an upgrade, a maintainer, or a planned move to Laravel.
Modernising a Legacy PHP Order System Without Stopping the Orders
An order system that takes money all day cannot be switched off for a rewrite. Here is how we modernise legacy PHP while orders keep flowing: map it, put tests around every path that touches a price, change the data in small steps and move modules across one route at a time.
When a Custom eCommerce Platform Makes Sense, and When Shopify or WooCommerce Is the Better Buy
A custom-built store gives you full control and full ownership, and full responsibility for everything a platform does quietly for its monthly fee. Here is how we decide whether a business genuinely needs its own eCommerce platform, what it really costs after launch, and the questions to settle before anyone writes code.
