Oort

Oort is an AI prompt library and prompt-engineering tool for solo developers and indie hackers where every listing has a shipped project attached. Instead of ranking prompts by upvotes, Oort ranks its library by real usage and logged runs, so you can clone prompts that actually shipped someone else's project rather than untested examples. It is bring-your-own-key (BYOK) across every major model with no markup on your API keys, and it includes a side-by-side playground for testing prompts across models before you commit. Listings show receipts such as run counts, the model used (for example Claude Opus), and links to the shipped project, giving each prompt a track record. The library is organized by task and workflow, with featured packs, repositories, case studies, and creator profiles, and the site reports usage stats like prompts live and models routed. For solo builders searching for the best AI prompt library that ships, Oort's differentiator is receipts and real-usage ranking over vanity metrics, plus a flat subscription that leaves your model API costs untouched. It is aimed squarely at one-person teams who want reusable, proven prompts and workflows.

Solo developers and indie hackers use Oort to find, clone, and test proven prompts and workflows that have already shipped real projects.
