CodeIgniter · QalbIT

CodeIgniter is not the point. The wait is.

We build with CodeIgniter for teams whose users are waiting too long: measured outcomes, written scope, and IP in your accounts.

Nobody asks for CodeIgniter. They ask why the dashboard takes four seconds and the form loses their input.

What we build with CodeIgniter

CodeIgniter development for lean web products.

We help founders and teams use CodeIgniter where it shines: a small, fast-shipping footprint for products that do not need a heavyweight framework.

  1. Booking and scheduling systems

    Courts, classes, appointments or resources, with the availability logic that keeps double-bookings out.

  2. Membership and subscription portals

    Plans, renewals and payment status handled in one place, integrated with Stripe or PayPal.

  3. Admin and back-office tools

    Role-based screens for staff to manage records, reports and day-to-day operations.

  4. CodeIgniter 3 to 4 upgrades

    A staged migration off CodeIgniter 3 that keeps the app running throughout, not a rewrite.

  5. HMVC restructuring

    A flat CodeIgniter app reorganised into modules so features stop colliding as the codebase grows.

  6. Performance rescue

    Slow queries and page loads profiled and fixed: measured before and after.

The CodeIgniter layer over the stack that carries it
CodeIgniter sits at the surface: the stack behind it matters just as much

How CodeIgniter projects run here

A practical CodeIgniter process, from audit to production.

We keep the CodeIgniter process structured but lightweight, so we can deliver a working build in real time without surprising you on quality, timeline or budget.

  1. Audit & architecture

    We read the existing code or the requirements, then propose the module structure, database schema and routes.

    Week 1

  2. Database & module design

    A normalised schema and clear module boundaries: the decisions that stop a CodeIgniter codebase rotting.

    Week 1–2

  3. Implementation & integration

    Build or refactor controllers and models, wire up payments or third-party APIs, handle validation properly.

    Sprint by sprint

  4. Testing, hardening & rollout

    Manual and automated checks on critical paths, security and performance passes, then a staged release.

    Pre-launch

  5. Ongoing support & features

    A standing team continues to ship features and keeps dependencies current.

    Post-launch

Where CodeIgniter earns its keep

CodeIgniter use cases we most often deliver.

Most of our CodeIgniter work is on small, operationally important systems, rather than public-facing marketing sites.

  • Court, class and resource booking

    Scheduling systems where double-booking a resource is the failure that matters most.

  • Membership and payments

    Recurring billing, plan changes and payment history in one admin view.

  • Internal operations tools

    Purpose-built screens for staff, replacing a spreadsheet or a paper process.

  • Legacy CodeIgniter 3 rescue

    A stalled or unsupported CodeIgniter 3 app stabilised and upgraded without a full rebuild.

The stack around CodeIgniter

The CodeIgniter stack we typically use at QalbIT.

We usually pair CodeIgniter with a small, well-understood toolset: PHP, a relational database and server-rendered views, so the app stays maintainable by a small team.

  • Core

    • CodeIgniter
    • PHP
    • Query Builder
    • Spark CLI

  • Data

    • MySQL or MariaDB
    • Migrations & seeders
    • REST API
    • Stripe or PayPal billing

  • Views & front end

    • Server-rendered PHP views
    • Bootstrap
    • jQuery
    • Composer packages

  • Quality & operations

    • PHPUnit
    • PHP_CodeSniffer
    • Role-based access control
    • Sentry or server logging

We adapt to what you already run. If your team is on a different templating approach or database, we work inside it rather than rewriting for preference.

CodeIgniter in production

Where CodeIgniter is the surface.

The same discipline on every build: a lean codebase, configuration over hard-coding, and the client owning the code.

Start here

Hire CodeIgniter developers who will still be proud of the code in year three.

Share your current application, goals and the problems you want to solve. We will review your requirements, look at any existing code and propose a practical CodeIgniter plan that matches your stage and budget.

  • A written scope with the exclusions listed
  • An architecture recommendation for modules and the database
  • The name of the engineer who would lead it
  • Free, and yours to keep either way

CodeIgniter development: frequently asked questions

Common questions about CodeIgniter builds, modernisation, security and team setup, plus what happens after launch.

Ask us directly →
Lightweight web applications and internal tools for teams already invested in CodeIgniter: booking systems, membership portals and admin tools that need to ship fast without a heavyweight framework. If you want a small footprint and a codebase a solo developer can still read in five years, CodeIgniter is usually the right call.
Both. Most of our CodeIgniter work is on an existing codebase: we start with a short audit that tells you honestly what is salvageable, what should be refactored and what each option costs.
Server-rendered views with Bootstrap and jQuery for most CodeIgniter apps, since that keeps deployment to one codebase. Where a project needs a richer interface, we build a separate React or Next.js front end against a CodeIgniter API.
A focused first release is usually six to ten weeks. A full product with integrations, billing and reporting runs ten to sixteen. You see a clickable prototype in the first two weeks.
Yes. Most clients keep a small standing team for features, dependency upgrades and performance work, with 30 days notice to stop or scale down.
Only if you are hitting CodeIgniter's ceiling: complex authorization, background jobs, or a team that wants a larger ecosystem. If the app is stable and the team is productive, we upgrade you to the current CodeIgniter release and keep shipping rather than migrate for its own sake.
Send us the goal and any existing code. You get a written scope, an architecture recommendation and a price range within 48 hours, free, and yours to keep either way.
