Ask HN: What are the best Open Source alternatives to popular SaaS?

Are there any specific providers' products you want alternatives to? Most of the ones I use are hosting open-source software that I could host myself, if I wanted, but it may not be so for your use.

i am currently using coolify, and I love it. I want to find a self hostable json database, which is more than a json file. Maybe self hostable alternative of jsonbin.io?

https://awesome-selfhosted.net/ is an excellent starting point to find projects that might suit your needs.

seems interesting! thanks!

for example:

netlify, render -> coolify

zapier -> n8n
