Not generalist PHP developers who've looked at CodeIgniter once. We have engineers who have built production CodeIgniter applications for 15+ years — CI3 maintenance, CI4 builds, REST API development, SaaS products, and full legacy migrations. ISO 27001 certified. NDA from day one.
CodeIgniter isn't legacy — it's lean. For teams who need fast delivery, low server overhead, and a framework that doesn't impose architectural decisions on them, CI4 remains one of the best PHP choices available.
Every project starts with understanding your specific requirements — not with fitting you into a service template. Here's what we build on CodeIgniter.
Our CI developers aren't siloed in one framework. They bring the full PHP ecosystem — front-end integration, DevOps, testing, and cloud deployment — to every project.
If you're running CI3, this is the honest picture. We can maintain it, extend it, or move you to CI4 — depending on what makes sense for your application and budget.
| Feature / Area | CodeIgniter 3 | CodeIgniter 4 ✓ |
|---|---|---|
| PHP Requirement | PHP 5.6+ (EOL) | PHP 7.4+ · PHP 8.x supported |
| Namespace Support | None — global functions and classes | PSR-4 namespaces throughout |
| MVC Structure | Loose, flexible (no enforcement) | Cleaner separation, enforced by default |
| Routing | Basic route definitions, limited groups | Route groups, middleware, named routes |
| Request / Response | Global functions ($this->input) | Proper Request / Response objects (PSR-7 style) |
| CLI Support | Basic, via URL mimicry | Built-in Spark CLI — migrations, generators, commands |
| Security | Manual — CSRF, XSS filtering | Built-in Security class, CSP headers, CSRF tokens |
| Testing | Limited official support | PHPUnit built-in, TestResponse helpers |
| Maintenance Status | No longer officially maintained | Actively maintained, regular security releases |
| Database Builder | Query Builder (basic) | Improved Query Builder with method chaining |
These aren't case study summaries written by a marketing team. They're the actual projects our CI developers have worked on, with the specifics of what we built and what happened.
CodeIgniter works across industries because it's a tool, not a product. We've applied it across these sectors — here's what that looks like in practice.
NDA before code is shared. ISO 27001 certified. And an honest 30-minute scope call before any proposal is made — so you know what you're getting into.
We don't start coding before we understand what you're building. But we also don't spend three weeks in discovery when a 30-minute call would do.
There are plenty of PHP development companies. Here's the specific case for working with us on a CodeIgniter project.
Start with a free 30-minute scope call. We'll understand your project, recommend the right developer, and have someone ready to meet you within 48 hours. No recruitment fee. No commitment until you're ready.
