Hello,

I’m going to give a presentation about Slim in December to the Paris PHP group. I’d like to list a selection of companies that use Slim. Do you know where I can find that?

[https://dhosting.pl/](https://dhosting.pl/) - I know that, because I am the one who does it. From server tools, through data collectors, staging services ending with ai agents. Currently I develop headless cms, and wait for a decision to rewrite the core application code.

[https://www.komputronik.com/](https://www.komputronik.com/) - I mentioned that long time ago.

Hello, @thierryler.  
This is very simple web-site of small company in Ukraine: [https://aimdent.com.ua/](https://aimdent.com.ua/). I made it using Slim framework. Hope, I’ve helped you a little bit.

I found some resources with companies and websites that use Slim:

According to StackShare, about 58 companies list Slim in their tech stack: [https://stackshare.io/slim](https://stackshare.io/slim)

Hello Thierry (@thierryler ),

I’m actually near Paris (and I use and plan to use slim for future projects), how can I join your presentation ? I’m very interested 🙂

We use Slim: [https://newmatter.eu](https://newmatter.eu) in most of our (non-static) projects, from browser games to SaaS services.

In the real world, Slim is best for small, focused apps or microservices. I’ve used it for APIs and headless CMS projects, and what makes it stick is how light and flexible it is. There’s no bloat, middleware is easy to connect, and routing is a breeze compared to full-stack frameworks like Laravel. The hard part is scaling past a few endpoints. You have to be smart about caching and dependency injection, or performance will drop. It’s great for anyone doing SaaS or game backend work like Paul said, but don’t try to fit a huge monolith into it.

> and what makes it stick is how light and flexible it is. There’s no bloat, middleware is easy to connect, and routing is a breeze compared to full-stack frameworks like Laravel.

How come above would be a contraindication to carry out large projects?

Are we still talking about Slim? I have an impression you just copy/paste something you heard/read around. It is Slim that allows you to solve all mentioned by you obstacles in ways impossible for other enterprise frameworks.

Speaking about the size, I had exactly two, quite a big enterprise challenges made with Slim, and it was a metaphysical experience, especially that one of them it was a complete rewrite of a Symfony6 hyped approach (although I may have exaggerated a bit with the enterprise thing, it was certainly nor Meta neither Netflix 🙂 ) In any case, these were big enough projects to make an impression.

> … but don’t try to fit a huge monolith into it.

This is more kind of a general remark not particularly related to Slim. Don’t try fit a huge monolith into anything. Modular monolith, is another story. Slim is perfect for that.

Finally to get to the point, would you share your experience and justify why wouldn’t you write anything big with Slim?

Olá,  
tem alguns bons exemplos para cache? como poderíamos explorar melhor essas melhorias para obter o melhor desempenho?

> Monólito modular é outra história

como eu poderia criar módulos autocontidos e independentes com o Slim?  
penso em fazer isso para reaproveitar módulos em vários projetos.

As I said in Slim4 it is very easy to create decoupled modules, the way that the same code can be used as a separate namespace code, the composer package, or a separate microservice (if it became too big at a certain moment), you just need to structurize your both module and appplication (frame) code in a certain way. This is a general vue of application (modular monolith scaffold) structure, with bootstrap file:

and this is how a module looks like:

as you can see both in terms of structure “parent” (application) and “child” (module) they are identical, an hooking module to your application is as easy as:

As you can see there is 6 modules (as composer packages) hooked to the monolith `OllamaAssistant`.
