Para

A general-purpose, open-source backend for the cloud.

About Para

Para is an open-source, stateless and schemaless backend that exposes a REST API over any database, search index and cache. A single executable JAR with an embedded database gives you users, social sign-in, permissions, full-text search and webhooks on first run, with no schema migrations or lock-in. Released under the Apache License, it targets developers prototyping and running applications, including LLM-based workflows, on infrastructure they choose.
