FlowGPT
Come here for character roleplay and to see what prompts real people actually run, not for a curated prompt resource you would use at work. The catalogue is unmoderated, much of the front page is adult roleplay, and the original prompt-engineering angle has largely been abandoned.
Pros
- genuinely large user-generated catalogue with voting, bounties and leaderboards
- the free tier covers most chat use without a card
- prompts and characters run in place, so you can test before copying anything out
Cons
- no quality control, so duplicate and low-effort entries dominate discovery
- the useful prompt-library function has been crowded out by roleplay characters
- no API and no export, so nothing you build here moves to another stack
- the operating company has rebranded and spread across other consumer apps, which puts the site's roadmap in question
