opensource alternative of langgraph platform or else some standard for building apis over graph

[AyushSonuu]

Problem:

Currently, developers must manually integrate LangGraph workflows with web frameworks like FastAPI or Django to serve them as APIs, manage authentication, logging, or data storage. There is no standard or plug-and-play framework that simplifies this integration and encourages best practices for:

• Routing and triggering LangGraph executions via HTTP endpoints
• Managing persistent sessions/state (like Django ORM or SQLAlchemy integration)
• Handling long-running tasks (async/streamed execution)
• Observability (logs, metrics, tracing)
• Configuration and modularity

Proposed Solution:

• Create a Django/FastAPI-inspired open-source framework for LangGraph. This framework would:
• Provide decorators or routers to expose LangGraph workflows as REST/GraphQL APIs
• Support LangGraph's start, resume, and update methods via standard HTTP verbs
• Allow session-based or token-based user management
• Integrate with database layers to store graph state, history, and logs
• Offer middleware for observability, error handling, and streaming responses
• Be modular, so users can plug in authentication, caching, task queues, etc.

Would be cool if there were an oss initiative to maintain an implementation of the agent protocol: https://github.com/langchain-ai/agent-protocol.

There's a dev one for JS: https://github.com/langchain-ai/langgraphjs-api/tree/main/libs/langgraph-api

but nothing with all the above features

Thanks so much for the insight and links! I’d love to contribute to an open-source initiative that brings full-featured LangGraph integration to Python, especially one aligned with the Agent Protocol spec.

Your suggestion resonates deeply with what I had in mind something that makes deploying LangGraph workflows as production-grade APIs as seamless as possible (routing, persistence, observability, streaming, etc.).

I'm very interested in dedicating my time and effort to this and would be grateful for the opportunity to contribute. That said, I'd really appreciate some guidance on where to begin perhaps a high-level roadmap or a set of priorities that could help bootstrap this effort in a way that aligns with LangChain's direction.

If there's any chance to collaborate on shaping this (even as a community plugin or LangGraph ecosystem repo), I'm all in!

@AyushSonuu I have started an OSS initiative to maintain a FastAPI-based implementation of the agent protocol with PostgreSQL persistence and LangGraph integration.

Check it out here:
https://github.com/ibbybuilds/aegra

Features:

• Agent Protocol compliance
• FastAPI + PostgreSQL backend
• LangGraph integration
• Self-hosted alternative to LangGraph Platform

Hi @ibbybuilds thank you for your support.
Also I can contribute to it.
We can connect together and talk about it.

Sure @AyushSonuu
