It is called Notifico.
I have worked in a bunch of tech companies, and in each of them there was a half-baked, in-house built notification server for sending emails and other notifications. So, I've collected the requirements, processed them and written the implementation in Rust!
The idea is simple: You send event_id and context (JSON object), and It loads the template, renders it with variables from the context, sends it to the recipient.
Features:
- No-code configuration. No knowledge of JS or other language is required.
- The templates can be edited without the need of backend developers.
- HA configuration with AMQP 1.0 support (e.g., RabbitMQ). Every component scales horizontally.
- Powerful templating language (it uses minijinja internally: https://github.com/mitsuhiko/minijinja)
- List-Unsubscribe support
- Admin interface for managing Events, Templates, and Pipelines.
Roadmap:
- Discord support
- Mattermost support
- Bounce email handling
- User-facing API for managing subscriptions
- Message view tracking and statistics.
- Tracking pixels
- Notification center implementation for Web and Mobile.
- Auto-retry for failed messages
- Template and Pipeline versioning
