What is this project?

fastapi-guard is async security middleware for FastAPI and Starlette. I'm the author. Features:

• IP and country allow and deny lists, user-agent filtering and cloud-provider blocking
• Rate limiting with automatic IP bans, with state shared across workers through async Redis
• SQL injection, XSS and other attack pattern detection on the request path, query, headers and body
• Per-route rules through decorators

Why is it awesome?

• Fully async: every check runs in the event loop without blocking the request, including the Redis-backed rate limits and bans.
• One middleware covers what otherwise takes several separate packages.
• Maintained and in production use: 65 releases (latest v8.1.1 on 2026-10-15) and about 62,000 PyPI downloads last month (pypistats).

Project background: Guard Core's first library is fastapi-guard, public since August 2024 (first PyPI release, 0.1.0, on 2024-08-26). It has 825 GitHub stars, 65 releases and about 62,000 PyPI downloads in the last month (pypistats.org). The framework-agnostic engines and the adapters for other frameworks and languages came later and run the same detection rules, checked in CI against shared conformance fixtures.
