Laravel vs CodeIgniter: How to Choose a PHP Framework

Most Laravel vs CodeIgniter comparisons are written by people who use one of them. We build and maintain applications on both, and the choice we recommend changes from project to project. The short version: Laravel suits a product that will keep growing, with several developers, background processing and integrations. CodeIgniter suits a lean application with a small team, modest hosting or an existing CodeIgniter codebase.

The rest of this article is the reasoning behind that, so you can test it against your own project.

Two different ideas of what a framework should do

Laravel is a full-stack framework. It expects to run the whole application: database models, templates, queued jobs, scheduled tasks, mail, notifications, file storage and tests, each with a documented convention. You get a lot on day one, and you agree to do things the Laravel way.

CodeIgniter 4 is deliberately small. It gives you routing, controllers, a model layer, validation, sessions and a command-line tool, and then stays out of the way. There is little hidden behavior. You can read a request from the route to the response without knowing much about the framework's internals.

Neither approach is better in general. A large convention set saves time when the project needs most of it and costs time when it needs a fraction.

Laravel vs CodeIgniter at a glance

	Laravel	CodeIgniter 4
In the box	Eloquent ORM, Blade templates, queues, scheduler, events, mail, notifications, file storage, test helpers	Routing, controllers, models over a query builder, validation, sessions, caching, email, the spark CLI
Added through official packages	API tokens, billing, queue dashboard and more	Authentication (Shield), settings, task scheduling, queues
Database layer	ORM with relationships, plus a query builder and migrations	Query builder and a model class with CRUD helpers, entities and migrations. No relationship mapping in the core
Learning curve	Steeper. Service container, facades and many conventions to absorb	Gentle. A small set of concepts and explicit code
Team fit	Conventions keep several developers consistent	Freedom that works well for one to three developers who agree on a structure
Hosting	Composer, command-line access and a process manager for queue workers	Installs from a zip or Composer and runs on ordinary shared hosting
Release rhythm	A major version about once a year, with dated support windows	Small, frequent releases within version 4. Only the newest release is maintained
Ecosystem	Large, with first-party and community packages for most needs	Smaller. More is written by hand or pulled from general PHP packages

Where Laravel earns its weight

Laravel pays off when the feature list is long and still growing. Typical signs:

• Background work. Emails, imports, exports, report generation and calls to slow third-party APIs belong on a queue, and Laravel's queue system and scheduler are part of the framework. We explain how they work in Laravel queues explained.
• Rich data models. Many related tables, where an ORM with relationships, eager loading and model events saves a great deal of repeated query code.
• Several developers. Strong conventions mean a new team member finds validation in form requests, authorization in policies and jobs in app/Jobs without asking.
• Standard product features. Subscriptions, API tokens, social login, search and real-time updates all have maintained packages, which shortens the path for SaaS products, marketplaces and customer portals.
• Automated testing as a habit. The test helpers for HTTP requests, database state and faked queues or mail are among the best reasons to choose it.

The cost is real. There is more to learn, more to upgrade and more happening behind each line. A junior developer can produce working Laravel code without understanding what it does, and that surfaces later as slow queries and surprises.

Where CodeIgniter is the better fit

• Focused applications. An internal tool, a booking form with an admin area, a reporting dashboard or a small API. If you would use a tenth of Laravel, the other nine tenths are still yours to update.
• Simple hosting. When the application must run on a client's existing shared hosting, with no long-running processes, CodeIgniter fits without workarounds.
• Developers who prefer explicit code. Queries are written with the query builder, classes are instantiated where they are used, and there is less to debug when something behaves oddly.
• Existing CodeIgniter systems. A team that has run a CodeIgniter 3 application for years will find version 4 familiar in spirit, even though the code has to be converted.
• Low request overhead. The framework loads little per request, which helps on small servers.

The cost here is the opposite one. As the application grows you write more yourself: relationship handling, authorization rules, job processing. With few conventions, structure depends on the discipline of whoever is on the team. A CodeIgniter project that grows for five years without agreed patterns becomes hard to hand over.

Hosting and running it in production

Both frameworks keep the application code outside the web root and serve from a public folder, and both need a current PHP version. Check each requirements page against what your host offers before you commit.

The practical difference is everything around the web request. A typical Laravel application runs queue workers under a process manager such as Supervisor, a scheduler entry in cron, and a deployment that runs Composer, migrations and cache commands. That is routine on a VPS or a managed platform and awkward on basic shared hosting. A typical CodeIgniter application is a set of files and a database. Deployment can be as simple as uploading a release, although we would still use Composer and migrations on anything that matters.

Release cycles and the cost of staying current

Laravel publishes a major version roughly once a year. Under its support policy, each one receives bug fixes for 18 months and security fixes for two years. In practice you plan a framework upgrade every year or two, and the upgrade guides are detailed. Skip three versions and the catch-up becomes a project.

CodeIgniter 4 moves in smaller steps. Releases within version 4 come with upgrade notes that usually take little time to apply, and the project states on its requirements page that only the newest version is maintained. So the rule is the same for both: update regularly or pay for it later. The one large jump in CodeIgniter's history is from version 3 to version 4, which is a rewrite and not an in-place upgrade.

Existing code usually decides

If you already have a working application, the framework question is mostly answered. A healthy Laravel application should stay on Laravel and be kept current. A CodeIgniter 4 application should stay where it is unless it has outgrown the framework in the ways listed above.

CodeIgniter 3 is the interesting case. It is in maintenance and receives mostly security fixes, so a move is coming sooner or later. Converting to CodeIgniter 4 keeps the mental model, the database and much of the business logic, and our guide to the CodeIgniter 3 to 4 migration shows what changes. Moving to Laravel is a larger rebuild and makes sense when the product needs queues, a richer data layer or a bigger hiring pool anyway. Both are conversions of the framework layer, so compare them on where the product is heading and not only on effort.

How to make the call for your project

Write down four things: the features planned for the next two years, how many developers will work on the code, where it will be hosted, and what code exists today. If the list includes background jobs, complex data, a growing team or SaaS features, choose Laravel. If it describes a contained application, a small team and plain hosting, CodeIgniter will cost less to build and to run. When the answers pull in both directions, weigh team and growth above hosting, because hosting is the easiest of the four to change.

If you would like a recommendation based on your requirements, we offer both Laravel development and CodeIgniter development, so the advice is not tied to one framework. For an existing CodeIgniter 3 system, the CodeIgniter 3 to 4 upgrade page explains how we approach the conversion.

Frequently asked questions

Is CodeIgniter still maintained?

Yes. CodeIgniter 4 is actively developed, with regular releases and official packages for authentication, settings, tasks and queues. CodeIgniter 3 is in maintenance mode and receives mostly security updates, which is why applications on it should plan a move.

Is Laravel too heavy for a small project?

It runs small projects without trouble. The question is upkeep: a small application on Laravel still needs yearly framework upgrades and a host that supports its tooling. If the project will stay small and nobody plans to extend it, a lighter framework is cheaper to own.

Which one is faster?

CodeIgniter does less work per request, so an untuned CodeIgniter page responds faster than an untuned Laravel page. With OPcache and Laravel's configuration and route caching enabled, the gap is small next to the time spent in database queries. Query design decides the speed of most business applications.

Can a CodeIgniter application be moved to Laravel later?

Yes. The database can usually stay as it is, and business logic that lives in plain classes carries over with little change. Controllers, models, views and authentication are rewritten. It is a rebuild of the application layer, planned module by module, and not an automated conversion.
