httpx2-ready

Is it on httpx2 yet? A daily-updated board of which of the 5000 most downloaded PyPI packages declare httpx, httpx2 or both as a dependency, plus a CLI to check your own requirements.

Live board: https://rafal-one.github.io/httpx2-ready/ (one page per package, e.g. /p/langchain-core.html, JSON at /data.json, RSS of flips at /flips.xml, badges at /badges/NAME.json).

httpx2 (the pydantic fork) is replacing httpx in the AI stack: openai 3.x, anthropic 1.x, mcp 2.x and huggingface_hub 2.x already switched, while many others still require httpx. Mixing both installs two HTTP stacks. This tool answers "does package X support httpx2 yet?" from declared metadata. Unofficial, not affiliated with httpx, httpx2 or pydantic. Pure stdlib, Python 3.9+.

pip install httpx2-ready     # or: pip install git+https://github.com/rafal-one/httpx2-ready

Check your own dependencies

$ httpx2-ready check openai langchain-core
openai 3.0.1          httpx2   httpx2 only
langchain-core 1.6.12 httpx    httpx only            >=0.23.0,<1.0.0

$ httpx2-ready check -r requirements.txt --fail-on httpx    # exit 1 if any pin is httpx-only
$ httpx2-ready check anthropic --json

Statuses: httpx2 (requires httpx2, not httpx), both, httpx (requires httpx only), optional (only in an extra such as [test]), none. Exit codes: 0 ok, 1 --fail-on matched, 2 bad input or unknown package, 3 network error.

Build the board yourself

httpx2-ready build --top 5000 --data data --out site      # ~3 minutes, ~5000 PyPI JSON requests
httpx2-ready build --no-fetch --data data --out site      # re-render only

The GitHub Actions workflow in ci/update.yml.example (copy it to .github/workflows/update.yml; pushing workflow files needs a token with the workflow scope) does this daily, commits data/state.json (status, since-date, flips) and deploys site/ to GitHub Pages. Requests are sequential-ish (4 workers), with a contact User-Agent and backoff on 429.

Also tracked per package: whether it caps mcp below 2 (pins-v1) and whether it still requires the sunset langchain-community.

Badge

[![httpx2](https://img.shields.io/endpoint?url=https://rafal-one.github.io/httpx2-ready/badges/YOUR-PACKAGE.json)](https://rafal-one.github.io/httpx2-ready/p/YOUR-PACKAGE.html)

Only packages in the top 5000 have a page and badge.

Limits

"Declared dependency" only: requires_dist of the latest release. It does not see vendored code, indirect use through other packages, or imports in the source. Python 3.9: the tool runs there, but httpx2 itself needs Python 3.10+. See also httpx2-audit for scanning your own code.
