It bridges two mature tools: Uvicorn for high-performance async HTTP handling and Gunicorn for robust process management, load balancing, and worker lifecycle control. You install it alongside gunicorn and uvicorn, then pass it to Gunicorn via the `-k uvicorn_worker.UvicornWorker` flag to spawn multiple worker processes, each running an ASGI app instance.\n\nThe main value is operational: Gunicorn handles worker spawning, graceful restarts, and dynamic scaling without you having to manage those concerns separately. You get Uvicorn's performance for async workloads combined with Gunicorn's battle-tested process supervision. The package supports Python 3.9 through 3.13 and offers an alternative UvicornH11Worker variant for PyPy-compatible environments.","worth_installing":"Yes, if you need to run ASGI applications under Gunicorn's process management model. The package has low install friction, permissive licensing, and no known vulnerabilities. However, maintenance is aging (no releases in 328 days), so evaluate whether the lack of recent updates poses a risk for your deployment timeline."},"id":"uvicorn-worker","links":{"html":"https://skillfed.io/packages/uvicorn-worker","md":"https://skillfed.io/packages/uvicorn-worker.md","pypi":"https://pypi.org/project/uvicorn-worker/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-09-20","license_spdx":"BSD-3-Clause","license_treatment":"permissive","name":"uvicorn-worker","python_support":"supports_current","summary":"Uvicorn worker for Gunicorn! \u2728"},"popularity":{"monthly_downloads":9551656,"position":1526,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.4.0"}
