aioapns
An efficient APNs Client Library for Python/asyncio
Decision gist · record as of 2026-08-14
Yes. aioapns is production-stable, permissively licensed, and actively maintained with low install friction. It is the right choice if you need to send iOS push notifications from a Python asyncio application and want a focused, efficient HTTP/2 client rather than a generic push service abstraction. The aging maintenance status (487 days since last release) is not a blocker for a mature library with no known vulnerabilities, but monitor the repository for any future APNs protocol changes.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later; APNs certificate or token credentials (key file, key_id, team_id, topic) must be obtained from Apple Developer account.
- Low install friction with three straightforward runtime dependencies (h2, pyOpenSSL, pyjwt).
- Repository shows active maintenance with a recent commit on 2025-04-14, though the package is aging relative to its release cycle.

What it is and what it does
aioapns is an asyncio-based client library for sending push notifications to iOS devices through Apple's Push Notification Service. It wraps the APNs HTTP/2 API with an efficient connection pool and supports both certificate-based and token-based (JWT) authentication methods. The library integrates directly with Python's asyncio framework, making it suitable for high-throughput, non-blocking notification delivery in async applications.
The package handles the low-level details of APNs communication—HTTP/2 protocol negotiation via h2, TLS certificate management through pyOpenSSL, and JWT token generation with pyjwt—so you only need to construct a NotificationRequest with a device token and message payload, then await the send call. It supports production and sandbox APNs servers, TTL and priority settings, and collapse keys for notification grouping.
Use it for
- Send real-time alerts and reminders to iOS app users from a Python backend service.
- Deliver high-volume push notifications (e.g., marketing campaigns) with connection pooling and async concurrency.
- Integrate APNs delivery into an asyncio-based microservice or event-driven architecture without blocking.
- Manage both certificate and token authentication flows for different APNs environments or team configurations.
- Set notification expiration (TTL) and priority levels for time-sensitive or background delivery scenarios.
