No—the package is abandoned (last commit 2024-07-30, no releases for 781 days) and classified as Pre-Alpha, making it unsuitable for production use. While the concept is sound and install friction is low, the lack of maintenance means it will likely break with future aiohttp updates.

Before you install
- Requires aiohttp and zlib-ng as runtime dependencies; optional isal package available for additional performance.
- Low install friction with only two runtime dependencies (aiohttp and zlib-ng), both standard packages.
- However, the project is archived and abandoned as of the last commit on 2024-07-30, with no releases for 781 days, raising concerns about future maintenance and compatibility with newer aiohttp versions.

Alternatives
Verify before relying
pip install aiohttp-zlib-ng
import aiohttp_zlib_ng
aiohttp_zlib_ng.enable_zlib_ng()- Whether the package remains compatible with current aiohttp versions given its abandoned status.
- Performance improvement magnitude compared to standard zlib in typical aiohttp workloads.
- Whether isal integration actually activates automatically or requires additional configuration.
What it is and what it does
aiohttp-zlib-ng is a thin wrapper that patches aiohttp's compression layer to use zlib-ng instead of the standard zlib library. zlib-ng is a faster, drop-in replacement for zlib that reduces CPU overhead during compression and decompression, particularly beneficial for WebSocket connections where compression happens frequently. The package automatically attempts to use isal (Intel's faster compression library) if available, falling back to zlib-ng otherwise.
You install it, call enable_zlib_ng() once at startup, and aiohttp automatically uses the faster compression for all subsequent connections. The package requires aiohttp and zlib-ng as runtime dependencies, both widely available. However, the project is archived and has not been maintained for over 781 days, which means it may not work with newer aiohttp releases or Python versions beyond those it was last tested against.
Use it for
- Reduce CPU usage in aiohttp servers handling high-volume WebSocket connections by replacing default compression.
- Speed up HTTP responses with large payloads by using faster compression without changing application code.
- Optimize latency-sensitive aiohttp applications where compression overhead is measurable.
- Enable optional isal compression for additional performance gains on systems where isal is available.
