Supabase
Open-source backend as service
Supabase is an open-source backend-as-a-service that provides a Postgres database, authentication, and real-time capabilities. As a source in a streaming ETL (Extract, Transform, Load) workflow, Supabase enables real-time data extraction from its database, allowing applications to react instantly to data changes. Its WebSocket-based subscriptions and built-in event triggers make it an ideal source for event-driven architectures.
