Apprise

Apprise is a notification library and CLI that lets applications send messages to many popular notification services using a single, consistent configuration format. It acts as a “notification gateway” you can embed in Python apps, scripts, monitoring tools, and automation workflows.

Key Features

• Large notification provider catalog (email, chat, push, SMS, incident/alerting tools, and more) with a unified configuration URL syntax
• Multiple interfaces: Python library/API, command-line tool, and plugin-style integrations
• Notification URL parsing/validation and service discovery to simplify configuration management
• Attachments support for providers that allow it (files/URLs) and rich message formatting where supported
• Tag-based targeting and grouping to route messages to specific destinations
• Config file support for managing multiple notification endpoints and reuse across scripts

Use Cases

• Send monitoring and uptime alerts from scripts or tools to Slack/Discord/Email/SMS
• Add a single notification layer to automation jobs (backups, CI tasks, cron jobs)
• Centralize alert routing for self-hosted services by mapping events to multiple destinations

Limitations and Considerations

• Provider capabilities vary (formatting, attachments, priority) and depend on each service’s API constraints
• Some integrations require third-party credentials/tokens and may break when upstream APIs change

Apprise is well-suited when you want one notification implementation that can be retargeted to many services without rewriting integrations. Its URL-based configuration and broad provider support make it practical for both small scripts and larger systems needing consistent alert delivery.
