Framework integration
How does Teleon integrate with LangChain and LangGraph?
Teleon uses gateway and callback-style integration patterns to apply policy and preserve evidence for LangChain chains, LangGraph runs, tools, state transitions, and agent activity.
Written and reviewed by Teleon · Updated 23 September 2026
Recommended integration
Use the Gateway for model traffic and framework callbacks for execution provenance. Sidecar can consume emitted evidence when independent policy evaluation is required.
Evidence available
- Chain, graph, node, and run relationships
- Tool requests and executions
- Selected state transitions and retries
- Policy decisions and integration metadata
Limitations
Visibility depends on callbacks, graph design, framework version, and which operations the application emits. Confirm coverage with a representative workload.
