HTTPCore 2

Test Suite (image) Package version (image)

> Do one thing, and do it well.

The HTTPCore 2 package provides a minimal low-level HTTP client, which does one thing only. Sending HTTP requests.

It does not provide any high level model abstractions over the API, does not handle redirects, multipart uploads, building authentication headers, transparent HTTP caching, URL parsing, session cookie handling, content or charset decoding, handling JSON, environment based configuration defaults, or any of that Jazz.

Some things HTTPCore 2 does do:

Sending HTTP requests.
Thread-safe / task-safe connection pooling.
HTTP(S) proxy & SOCKS proxy support.
Supports HTTP/1.1 and HTTP/2.
Provides both sync and async interfaces.
Async backend support for asyncio and trio.

Installation

For HTTP/1.1 only support, install with:

pip install httpcore2

There are also a number of optional extras available...

```shell pip install...

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

HTTPCore 2 is a minimal low-level HTTP client library providing thread-safe and task-safe connection pooling with support for HTTP/1.1, HTTP/2, proxies, and both sync and async interfaces.

Low install friction with only two runtime dependencies (h11 and truststore). Actively maintained with a release 4 days old; the repository shows recent commits and 909 stars. Supports Python 3.10–3.15.

BSD-3-Clause (permissive) allows commercial and private use with minimal restrictions, requiring only license and copyright notice retention.

Usage

pip install httpcore2

import httpcore2

http = httpcore2.ConnectionPool()
response = http.request("GET", "https://www.example.com/")
print(response.status)

Requires Python 3.10 or later.

Verdict: HTTPCore 2 is a well-maintained, actively developed low-level HTTP client with minimal dependencies and no known vulnerabilities. Its permissive BSD-3-Clause license and recent release cadence make it suitable for production use, though it is intentionally bare-bones and best used as a foundation for higher-level libraries rather than directly in most applications.

Needs verification

Whether optional extras (asyncio, trio, http2, socks) add significant install friction or are commonly required.
Performance characteristics compared to alternatives for typical workloads.
Adoption rate and stability signals beyond star count and release frequency.
