어떤 프로젝트인가요?

cap is a self-hosted CAPTCHA replacement that skips puzzles like clicking traffic lights. Instead, the visitor's browser quietly solves small challenges in the background, including GPU-resistant proof-of-work and instrumentation checks. The project is designed so no third party sees visitor data, and the challenges can be tuned to slow down autonomous AI agents that consume server resources.

The project has no dependencies by default and can be deployed with Docker, on Cloudflare Workers, or on Railway. The README states it is roughly 200 times smaller than hCaptcha and names bunny.net and AdGuard as production users.

The widget is distributed through npm packages under the @cap.js scope, including a WebAssembly build for browser-side solving.

핵심 기능

  • 01Replaces image puzzles with background proof-of-work and instrumentation challenges.
  • 02Self-hosted, so visitor data stays on your own infrastructure.
  • 03Includes configurable challenges aimed at autonomous AI agents.
  • 04Runs with no dependencies by default.
  • 05Deployable via Docker, Workers, or Railway.

활용 사례

  • Protecting login, signup, or comment forms from bots without showing puzzles to users.
  • Adding a privacy-respecting CAPTCHA to sites that must avoid third-party trackers.
  • Limiting scraping and automated abuse of public APIs or web pages.
