libcaptcha

Lib stands for Libre — free as in freedom, not just free as in price.

Open-source, self-hostable captcha. No tracking, no telemetry, no lock-in. Server-side proof-of-work and cryptographic verification — fully transparent. Client-side polymorphic WASM VM raises the cost of automated solving. Drop-in SDK or standard HTTP API.
