Keel
Keel is the base framework I use to build most web application projects on.
A lightweight, zero dependency, PHP framework. It starts out of the box with users, auth, and organizations. It the base for every multi-tenant system and saves a lot of time.
Why
Zero dependency so I don't have to ready every supply chain attack article and worry. Don't get me wrong, I still worry about security, but I like the peace of mind of not having to wonder who contributed to some library I implemented 3 years ago because I was too lazy to do it myself.
Why php? I find modern php a very capable language. It's easy to read, easy to write, it runs efficiently, It's mature and well supported, and lower model LLMs handle it very well as long as you give them some direction. It's my go to for server side in a web application.
Keel is public on my github. It's free to use but it was never indented to be used by anyone other than me.
