DuraGraph
Mission
Section titled “Mission”DuraGraph provides an open, extensible orchestration layer for AI and workflow automation. Our mission is to enable reliable, observable, and maintainable pipelines that feel natural for developers—bringing the power of LangGraph Cloud to self-hosted and enterprise environments.
Compatibility with LangGraph Cloud
Section titled “Compatibility with LangGraph Cloud”DuraGraph implements an API-compatible layer with LangGraph Cloud. This means:
- Tools, clients, and SDKs built for LangGraph Cloud can run against DuraGraph.
- OpenAPI contracts are aligned for seamless integration.
- Migration and hybrid deployments are supported.
Architecture
Section titled “Architecture”DuraGraph is built on proven technologies for reliability and performance:
- Event Sourcing for complete audit trails and state reconstruction
- CQRS (Command Query Responsibility Segregation) for scalable reads and writes
- PostgreSQL for durable event storage and projections
- NATS JetStream for reliable event streaming
- Custom Graph Engine for workflow execution with support for conditionals, loops, and human-in-the-loop
This ensures fault tolerance and deterministic execution for AI-driven processes.
Target Users
Section titled “Target Users”- AI platform teams building internal orchestration layers.
- Enterprises that require compliance, security, and observability in AI workflows.
- Open-source contributors looking for a community-driven orchestration stack.
- Researchers who want to run reproducible LangGraph experiments locally.
Non-Goals
Section titled “Non-Goals”- Providing a custom LLM runtime (we integrate with existing providers).
- Becoming a full-featured cloud platform (our scope is orchestration, not hosting).
Success Metrics
Section titled “Success Metrics”We measure success by:
- Adoption: # of teams using DuraGraph in production.
- Compatibility: seamless drop-in replacement for LangGraph Cloud APIs.
- Reliability: demonstrated ability to recover from failures without data loss.
- Community growth: contributions and RFCs from external developers.
