aioitertools
itertools and builtins for AsyncIO and mixed iterables
Decision gist · record as of 2026-08-14
Yes. Low install friction, permissive MIT license, active maintenance, no vulnerabilities, and a narrow, well-defined scope make this a safe dependency for async code that needs familiar iteration patterns. Install if you work with async generators and want to avoid writing custom iteration wrappers.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or newer
- Low friction: pure Python wheel with a single lightweight dependency (typing_extensions).
- Active maintenance with recent release; repository shows steady engagement.

What it is and what it does
aioitertools shadows the standard library's itertools and builtins modules to provide async-first equivalents. It lets you use familiar functions like map, zip, chain, and islice directly on async generators and coroutines, without wrapping or manual iteration logic. The package accepts both standard iterables and async iterables interchangeably, so you can mix them in the same call.
Typical usage involves importing async versions of functions you already know, then using them in async for loops or with await. It requires Python 3.9 or newer and has only one runtime dependency. The package is maintained actively and carries no known security vulnerabilities.
Use it for
- Fetch multiple URLs concurrently and process results as they arrive using async map
- Combine output from multiple async generators into a single stream with chain
- Zip together async iterables for parallel processing in an async for loop
- Slice or filter async generator output without materializing the entire sequence
- Replace manual async iteration boilerplate in mixed-type iteration scenarios
