Ask HN: Favorite place to discover open source projects?

I often skim through various "awesome lists" (e.g. [1]) and communities interested in open source apps like r/selfhosted [2]

[1] https://github.com/awesome-selfhosted/awesome-selfhosted

[2] https://www.reddit.com/r/selfhosted/

I really like using the Github mobile app and scrolling through it's "Explore" feed

Crowdsupply for open hardware: https://www.crowdsupply.com

i find twitter for quick peek then reddit for deep discussions then linkedin to post cringe posts to be cool in front of HR people
