Typed, resilient HTTP clients for Python — typed errors, typed response bodies, and composable resilience (retry, bulkhead, circuit breaker), sync or async.
Why httpware
- Errors you can catch by name — a 404 raises
NotFoundError, a 429RateLimitedError, automatically; everything else bubbles up under onehttpware.StatusErrorbase. Noraise_for_status(), no status-code branching. - Typed response bodies —
response_model=Userdecodes the body straight to your pydantic or msgspec type; a missing decoder fails fast, before the request goes out. - Composable resilience — retry + retry-budget, bulkhead, circuit breaker,
and timeout as middleware over standard
httpx2.
Built on httpx2: httpware re-exports httpx2.Request/httpx2.Response and stays a thin wrapper, not a new HTTP abstraction.
Status: Pre-1.0. Public API is subject to change between minor releases until v1.0.
Install
pip install httpware # core only — no decoder
pip install httpware[pydantic] # + PydanticDecoder — BaseModel, dataclasses, primitives, generics
pip install httpware[msgspec] # + MsgspecDecoder — Struct, dataclasses, primitives, generics
pip install httpware[pydantic,msgspec] # both — BaseModel routes to pydantic, Struct to msgspec
pip install httpware[all] # everything (pydantic, msgspec, otel)
Quickstart
A typed GET against a live API (needs pip install httpware[pydantic]):
import asyncio
from httpware import AsyncClient
from pydantic import BaseModel
class User(BaseModel):
id: int
name: str
async def main() -> None:
async with AsyncClient(base_url="https://jsonplaceholder.typicode.com") as client:
user = await client.get("/users/1", response_model=User)
print(user.name) # Leanne Graham
asyncio.run(main())
The sync Client is identical — swap AsyncClient → Client and drop the await / async with. A 4xx/5xx response raises a typed StatusError; a malformed body raises DecodeError. Both subclass httpware.ClientError.

Full guides live at httpware.modern-python.org:
- Quickstart & observability — resilience middleware, streaming, and the stable logger/event contract.
- Middleware — write your own (auth, tracing, request-ID propagation).
- Resilience — retry + retry-budget, bulkhead, circuit breaker, timeout.
- Errors — the exception tree and catching strategies.
- Testing —
httpx2.MockTransportinjection. - Recipes — DI wiring, phase-decorator patterns, link-header pagination.
