I really like prompts.chat because it feels less like a “prompt dump” and more like a place to actually discover good prompts.
Browsing is super easy (categories/tags + search/filters), and the prompts themselves aren’t just random one-liners; you’ll find structured templates and longer, more useful setups too. The “Featured” section helps a lot when you just want the good stuff fast.
Also, being free/open-source and even self-hostable is a huge plus. It’s simple, practical, and clearly built by people who actually use this stuff.
