I've analyzed the tech stack of nearly 500 open-source companies

I run a website dedicated to gathering the best open-source companies. Recently, I analyzed the technologies each company uses. It was a challenging task, but I was able to identify nearly 250 different languages, frameworks, and development tools.

Enjoy!

I don't get why React is still so popular in 2025, even though it's slower than many JS frameworks like Vue, Lit or Svelte.

Also: PHP, C and Ruby are still somewhat popular in 2025.
