The browser side is the `cap-widget` package from npm, a web component that a site can also load from a CDN. The server side is Cap Standalone, a Bun program that runs from the `tiago2/cap` Docker image, keeps its data in Redis or Valkey, and offers a web dashboard for site keys, a REST API and a verification endpoint compatible with reCAPTCHA. The project is made by tiago.zip.\n\n## Worth knowing\n\nThe widget and the standalone server have separate release lines in one repository."}
