2024 Best Micro Frameworks for PHP
Introduction
Well it's August 2024 and it's time for another framework comparison! In the world of web development, PHP micro frameworks have become a popular choice for developers looking to create lightweight, efficient, and fast applications. These frameworks offer the core functionalities required to build web applications without the overhead of full-stack frameworks. Many projects developed with this frameworks are for creating RESTful APIs and they have been optimized to cater to these projects. This article will compare five popular PHP micro frameworks: Slim, Flight, Fat-Free, Silex, and Lumen. We'll examine them based on their community level, simplicity, performance, and ease of use to help you decide which one is the best fit for your project.
Slim Framework
Community Level
Slim has one of the most active communities among PHP micro frameworks. With a large number of contributors and extensive documentation, it's easy to find support, resources and example projects out there.
Simplicity
Slim is designed to be simple and intuitive. It follows a straightforward approach, allowing developers to quickly set up routes and middleware. For a light weight framework it does have several dependencies which can turn away some developers. It also needs additional package configuration out of the box to get it to handle the requests and responses in a way that is useful for most developers.
Performance
Slim is highly performant compared to full stack frameworks, thanks to its lightweight nature. Despite it not including unnecessary features, it is one of the heavier micro frameworks in terms of performance.
Ease of Use
Ease of use is one of Slim's strongest points. Its clear documentation and examples make it easy to get started. The framework also supports PSR-7 and PSR-15 standards, making it compatible with various middleware and components.
Flight Framework
Community Level
Flight has a smaller, but dedicated community. While not as large as Slim's, it still offers good support through chat and GitHub.
Simplicity
Flight prides itself on being minimalist. Its API is clean and concise, which allows developers to build applications quickly without getting bogged down by complexity. It's documentation has recently been revamped and is now more user friendly than ever.
Performance
Flight's performance is solid, given its minimalistic design. It avoids adding overhead, ensuring fast response times for applications. Out of all the frameworks here, according to the TechEmpower benchmarks, Flight is consistently the fastest beating out the next leading competitor (Slim) by an average of 50% and beating out Lumens by an average of 125%!
Ease of Use
Flight is user-friendly, with a gentle learning curve. It is meant for a newer developer just breaking into the framework world or for the seasoned developer that wants control over more aspects of their project. Its simplicity makes it accessible to new developers, while its power appeals to experienced ones looking for a straightforward solution. There is also a page dedicated to help compare Flight to other frameworks to help you make a decision.
Fat-Free Framework (F3)
Community Level
Fat-Free Framework has a moderately active community. There are sufficient resources available, including documentation and community support.
Simplicity
Fat-Free Framework aims to be both simple and powerful. It includes a range of features out of the box, which can sometimes complicate its simplicity. However, it provides a good balance between functionality and ease of use.
Performance
F3 is known for its high performance. Its efficient design and minimalistic core ensure that applications run smoothly and quickly.
Ease of Use
Fat-Free Framework is relatively easy to use, though the abundance of built-in features can be overwhelming for beginners. Once familiar with its capabilities, developers can take full advantage of its robust functionality.
Silex Framework
Community Level
Silex had a robust community, largely due to its association with Symfony. Although Silex itself has been discontinued, the community support and resources are still available through Symfony channels.
Simplicity
Silex is simple and elegant, designed to leverage the power of Symfony components without the bloat. Its design makes it easy to create powerful applications with minimal effort.
Performance
Performance is not one of Silex's strengths, however it does benefit from the optimization of Symfony components. It provides a lightweight yet powerful foundation for web applications.
Ease of Use
Silex is user-friendly for those in the Symfony ecosystem. Its integration with Symfony components makes it easy to extend and enhance applications as needed.
Lumen Framework
Community Level
Lumen probably has the largest and most active community, supported by Laravel. This ensures abundant resources, documentation, and community support.
Simplicity
Lumen is designed to be simple and "fast". It strips down Laravel to its essentials, providing a streamlined framework for building microservices and APIs.
Performance
Lumen is built for performance, optimized for speed and efficiency. Despite that, it consistently is nearly dead last in most benchmarks.
Ease of Use
Ease of use is a hallmark of Lumen, particularly for developers familiar with Laravel. Its clear documentation and extensive resources make it easy to get started and build robust applications. However, it now no longer recommended to use Lumen and to use Laravel instead which highlights that it's very likely to be discontinued in the future.

I've tried Slim, Fat Free and Flight, Flight has been the one I felt most at home with. It takes care of the things I expect from a framework , without feeling like I am fighting against it to make it do what I need it to.
Thanks so much! I'm glad you're enjoying it! I've used it too and have really been enjoying my time with it!
Good article.
Are there any specific usecases those frameworks are best for? The reason I am asking is that I read Slim is the best API framework in php.
So it's interesting, all of these frameworks come with the bare bones that you can attach other things to. For slim, you can just do it for restful APIs, or you could build a full web app by attaching a container and adding different services. You could do the same with Flight and Fat-Free as well. Lumen is on it's way out to just being offered as Laravel only (following what Symfony did with Silex).
There are some core differences between how these frameworks approach to building a web app. That said, I would say Slim and Flight are your best bets for keeping it clean long term, and if I had to pick one over the other, I would pick Flight because it has no dependencies and just enough "extras" to still feel bare bones, but to have some added extras where you could get away with doing a simple API with no added packages. FatFree has a little more "built in" but it does have some dated practices like no real middleware, but there are workarounds to make it "seem" like it has middleware.

No mention to Tempest
Ha yes Tempest is new to the game and brendt_gd is doing an awesome job with it! It’s still in beta and it’s geared towards a full stack framework whereas these are smaller “lite” frameworks.
Six years after its discontinuation it's hard to find recent activity and ressources concerning Silex, except some old forks.
What are the "the community support and resources are still available through Symfony channels" you are talking about ?
Just meaning through forums and such you can still ask questions and get heckled, but still get some help.
Hey Hi.
I discovered Slim PHP in 2017. We use it a lot at work, and I like it. 🤗
Are you the author/maintainer of Flight? Congrats!
I'll take a look later and give it a try...
I'm not the original author of Flight but yes I've taken the torch so to speak. Put a lot of work into getting it to where it is now. It's helped a few other devs I know learn some really practical lessons with PHP and taken their PHP code to the next level. I hope it can help others in a similar way.
I discovered Slim around the same time. Slim v3 was great but Slim v4 was not a great transition. I really really REALLY didn't like the direction it too. It looks like from some github issues I've seen that Slim v5 is hopefully a step back to simplicity? I hope so.
Yeah, last night, I kept reading and learned more about Flight PHP.
Nice Work! 👏👏👏
Great content!
I am just in the process of deciding between F3 and Flight.
Thanks
There is a chat room for Flight on matrix and you an ask any questions you want. Several of us have programmed several projects in both Flight and F3. matrix.to/#/#flight-php-framework:...
