Sibuna is an open-source web application firewall that uses browser-based proof of work (sequential work or Hashcash) to impose computational costs on bot traffic. It bundles a reverse proxy, access policies, TLS fingerprinting, application inspection, rate limiting, and an operator console into a single Rust executable with cross-platform support and optional clustering via PostgreSQL. It stands out for integrating proof-of-work admission control with traditional WAF features and shipping a polished, embedded console.
Target audience: devops, backend devs, security engineers
