webpush-rs

Fast Web Push (VAPID + AES128GCM) for Python — the Rust web-push crate behind a PyO3 binding.

The VAPID JWT signing and payload encryption run in native Rust; Python sees a single blocking send_one. Compared to a pure-Python sender it roughly halves per-send CPU and adds no Python dependency footprint (the crypto is statically linked, not pulled in as cryptography/http-ece).

End-to-end latency is dominated by the network round-trip to the push service (FCM/Apple), so this is not "faster delivery" — it's lower CPU and memory on the sending host, which matters when fanning out to many subscribers.

Install

pip install webpush-rs        # or: uv pip install webpush-rs

Prebuilt wheels are published for CPython 3.8+ (abi3, one wheel per platform) on Linux (manylinux x86_64 + aarch64), macOS, and Windows.

Usage

import asyncio
import webpush_rs

# send_one is blocking (it drives a small internal Tokio runtime); call it off
# the event loop from async code.
status = await asyncio.to_thread(
    webpush_rs.send_one,
    endpoint,        # subscription.endpoint
    p256dh,          # subscription.keys.p256dh
    auth,            # subscription.keys.auth
    vapid_private,   # url-safe base64 VAPID private key
    "mailto:you@example.com",  # VAPID subject (mailto: or https URL)
    payload_bytes,   # the notification payload
)
# 201 = delivered; 404/410 = endpoint gone (delete the subscription); 0 = error (raises).
