It identifies requests by IP and path by default, but supports custom identifiers like user ID. When a limit is exceeded, it raises an HTTP 429 response by default, though you can provide a custom callback. The package works with both REST endpoints and WebSocket connections, and allows stacking multiple limiters on a single route with different thresholds.\n\nThe package integrates directly into FastAPI's dependency injection system, so rate limiting is declared as a route parameter rather than middleware. It supports Python 3.9 through 3.14 and has no known security vulnerabilities. The aging maintenance status reflects infrequent releases, but the repository remains public and the dependency surface is minimal.","worth_installing":"Yes, if you need straightforward per-route rate limiting in FastAPI. The low install friction, permissive license, and zero known vulnerabilities make it a safe choice. The aging maintenance status (189 days since last release) is a minor concern but not a blocker\u2014the package is stable and the dependency chain is minimal. Install it if your use case fits the built-in features; consider alternatives if you need distributed rate limiting across multiple instances."},"id":"fastapi-limiter","links":{"html":"https://skillfed.io/packages/fastapi-limiter","md":"https://skillfed.io/packages/fastapi-limiter.md","pypi":"https://pypi.org/project/fastapi-limiter/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2026-02-06","license_spdx":"Apache-2.0","license_treatment":"permissive","name":"fastapi-limiter","python_support":"supports_current","summary":"A request rate limiter for fastapi"},"popularity":{"monthly_downloads":942954,"position":4673,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.2.0"}
