pyfcm
Python client for FCM - Firebase Cloud Messaging (Android, iOS and Web)
Decision gist · record as of 2026-08-14
Yes, if you are building a Python application that needs to send Firebase Cloud Messaging notifications to mobile or web clients and can provide a service account or OAuth2 credentials. The package is stable (Production/Stable classifier), has no known vulnerabilities, and handles the FCM HTTP V1 API migration. However, be aware that maintenance is aging (382 days since last release); verify compatibility with your target Python version, as the classifiers list only up to Python 3.5.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a Firebase service account JSON file or valid Google OAuth2 credentials with firebase.messaging scope; project_id must be specified.
- Low install friction with a pure-Python wheel distribution.
- Maintenance status is aging—last release was 382 days ago—but the repository remains active with a recent commit on 2026-01-16 and no archived status.

What it is and what it does
PyFCM wraps the Firebase Cloud Messaging REST API to let Python applications send push notifications and data payloads to mobile and web clients. It handles authentication via service account files or Google OAuth2 credentials, supports sending to individual devices, topics, and conditional topic subscriptions, and allows platform-specific configuration for Android (android_config), iOS (apns_config), and Web (webpush_config). The package abstracts away HTTP details and credential management, letting developers focus on message construction and delivery.
The library supports both notification messages (which FCM displays on the client's behalf) and data-only messages (which the client app processes), as well as combined payloads. It includes support for Tornado and can route requests through HTTP proxies. Initialization requires either a Firebase service account JSON file or pre-configured Google credentials and a project ID; messages are sent via the notify() method with optional dry-run testing.
Use it for
- Send push notifications to mobile app users when new data is available or to drive user re-engagement.
- Deliver time-sensitive alerts to Android, iOS, or Web clients subscribed to specific FCM topics.
- Send custom data payloads (up to 4KB) to client applications for in-app processing without displaying a system notification.
- Implement conditional topic messaging to reach users matching specific subscription criteria.
- Test notification delivery in a staging environment using the dry_run parameter before sending to production.
