Sibuna is a Rust-based web application firewall that uses browser proof-of-work challenges to mitigate bot traffic, with optional application inspection, rate limiting, and an operator console. It stands out for its efficient single-binary design, WebAssembly-based solver, and cluster support, offering a novel cost-based admission mechanism instead of traditional captchas.
