About

What is aegra?

Aegra offers an open-source, self-hosted AI agent backend, serving as a direct alternative to LangGraph Platform (now LangSmith Deployments). Built with FastAPI and PostgreSQL, it provides developers with zero vendor lock-in and complete control over their agent infrastructure. Key features include Agent Protocol compliance, a robust worker architecture with Redis job queue for horizontal scaling and crash recovery, human-in-the-loop capabilities, and real-time SSE streaming. It supports persistent state via PostgreSQL checkpoints, configurable authentication (JWT, OAuth, Firebase), unified observability through OpenTelemetry, and semantic storage with pgvector. Aegra is compatible with existing LangGraph SDK code and integrates with tools like Agent Chat UI, LangGraph Studio, and CopilotKit, making it ideal for building and deploying scalable AI agents.

Best used for

Ideal for developers and data scientists who need to self-host AI agent backends, ensure zero vendor lock-in, and maintain full control over their agent infrastructure. Especially valuable for those migrating from LangSmith Deployments or building scalable, custom AI applications with FastAPI and PostgreSQL.

FAQs

What is the primary benefit of using Aegra over LangSmith Deployments?

Aegra offers an open-source, self-hosted solution, providing zero vendor lock-in and full control over your AI agent infrastructure. This contrasts with LangSmith Deployments, which often involves managed services and potential vendor dependencies, especially for enterprise features.

What technologies does Aegra leverage for its backend and persistence?

Aegra is built using FastAPI for its HTTP layer and PostgreSQL for persistent state and checkpoints. It also utilizes Redis for its job queue, SSE pub/sub, and crash recovery, along with OpenTelemetry for unified observability and pgvector for semantic storage.

Can I use my existing LangGraph code with Aegra?

Yes, Aegra is designed to be a drop-in replacement for LangSmith Deployments and is fully compatible with the LangGraph SDK. You can use your existing LangGraph code without changes, simply by pointing your client to the Aegra server URL.
