Aegra

Aegra is an open-source backend for deploying and managing AI agents built with LangGraph. It functions as a drop-in replacement for LangSmith Deployments, allowing developers to run agents on their own infrastructure using PostgreSQL for persistence. The project describes itself as an alternative to LangSmith Deployments, eliminating vendor lock-in while maintaining compatibility with the LangGraph SDK.

The platform includes Docker-ready deployment, custom authentication (JWT, OAuth, Firebase), multi-LLM support, Agent Protocol compliance, and OTLP-compatible tracing. It supports streaming responses, checkpoints, and integrates with existing LangGraph tools like Agent Chat UI and LangGraph Studio. According to the repository, it was built with FastAPI and PostgreSQL.
