Happy Eyeballs for asyncio
Decision gist · record as of 2026-08-14
Stable, actively maintained library in the top 100 PyPI packages with zero known vulnerabilities. Ideal for applications needing RFC 8305 Happy Eyeballs behavior when using pre-resolved addresses or alternative DNS methods; permissive PSF license and zero dependencies make adoption straightforward.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; asyncio event loop must be running.
- Low friction: pure Python wheel with no runtime dependencies, actively maintained with recent releases, and supports Python 3.10–3.14.
