httpx is no longer actively maintained. httpx2, maintained by Pydantic, is its direct continuation — same API, same design philosophy, same everything. Only the package name changes.

Migrating is a one-liner:

pip install httpx2

And a global find-and-replace in your codebase:

import httpx  →  import httpx2

That's the entire migration. No architectural changes, no new concepts to learn.

Pydantic uses httpx2 in their own AI products, which gives the project a concrete reason to stay healthy and receive timely security updates — particularly important for a library that sits in the request path of so many production systems.
