OWASP Coraza WAF is a free, open-source Web Application Firewall for APIs and web applications. It supports ModSecurity SecLang rulesets and is fully compatible with the OWASP Core Rule Set.

Coraza can run as a sidecar, proxy or library in Go, C++ and WebAssembly. Official connectors are listed for NGINX, Envoy, Caddy, Apache APISIX, proxy-wasm, HAProxy, Traefik and libcoraza. Documentation describes extension points for audit loggers, persistence engines, operators, actions and plugins, with examples for GeoIP and a package containing the Core Rule Set and recommended configuration. The Quick Start requires Go 1.24 or later. Platforms listed are API, Linux, macOS and self-hosted. Coraza offers managed rule sets, API protection and bot management. The v3 internals documentation says persistent collections such as IP, SESSION and RESOURCE are not currently supported. Coraza Playground provides a sandbox web interface for testing rules. The Open source plan is listed at free.
