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).
