BookHoarder turns a local folder, S3 bucket, or Cloudflare R2 bucket into a browsable EPUB library. Read in the browser, keep progress for each profile, organize shelves, fetch metadata from Open Library, send books by email, or connect through OPDS. There is no database to run or migrate. Deploy it with Docker, Kubernetes, or Cloudflare Workers.
Track user engagement and website traffic with a simple REST API. Free unlimited API with JavaScript and Go libraries. No database required, setup in 1 minute.
I ve been building APIs for a while, and one of the recurring headaches is rate limiting. Most tools are either too rigid, too slow, or don t let you limit on custom criteria (like by user ID, API key, or plan).
