Ask HN: Any valuable free online resources for Dev at the end of 2024?

Want to do some sick project in this Christmas like someone used to hack sqlite's VFS layer to run on Cloudflare and now turned it into full blown product.

There's only a few that I know are good. Oracle Cloud does provider a generous plan for free devs. What about anything new that are available in 2024 that I actually missed as a dev?
