LangGraph is the library you build with. LeafMesh is the operations fabric you run and govern with. They're complementary, not competitive.
Use LangGraph to build agent workflows in code. Use LeafMesh ADK to deploy, govern, and observe those workflows in enterprise production.

Note: complementary, not competitive
Best practice: build agent flows in LangGraph, deploy and govern them through LeafMesh ADK. LeafMesh treats LangGraph workflows as first-class agents.
LeafMesh ADK is a YAML-first, vendor-agnostic agent operations fabric for governing, orchestrating, and auditing enterprise AI agents in production. It adds audit trails, observability, multi-vendor support, policy enforcement, and human-in-the-loop primitives.
LangGraph is an open-source library from LangChain for building stateful, graph-based agent workflows in Python. It's developer-first, code-centric, and gives fine-grained control over agent state machines.
LangGraph is an open-source Python library for building agent workflows as stateful graphs. It exposes nodes, edges, and state machines as code, giving developers complete control. It is part of the LangChain ecosystem and is best for prototyping and code-first agent design.

LeafMesh ships 18 working templates with 235 verified agent roles across sales, support, finance, HR, and operations — scaffolded in one command. (create-leafmesh 2.4.0 template registry, June 2026.)
LeafMesh pricing is $99/month with 5,000 agent invocations included, then a flat $0.06 per invocation — the same rate across human, LLM, and system agents. (LeafCraft pricing, June 2026.)
LeafMesh orchestrates agents across 8 first-class LLM providers — OpenAI, Anthropic, Google Gemini, AWS Bedrock, Azure Foundry, Google Vertex AI, DeepSeek, and local / self-hosted models — through one YAML runtime; models from Mistral, Cohere, and Llama are reachable via Bedrock and Vertex. (LeafMesh ADK documentation, June 2026.)
Across live deployments, customers measured a 60% reduction in manual coordination time, 3× faster ticket-to-deployment cycle time, and 100% decision audit coverage. (LeafCraft deployment data, 2026.)
Not exactly — they sit at different layers. LangGraph is a library for building agent workflows. LeafMesh ADK is the operations fabric that runs and governs those workflows in production with audit trails, multi-vendor support, observability, and human oversight. Most teams use them together.
Yes. LeafMesh treats LangGraph workflows as first-class agents. You build the flow in LangGraph, then deploy it under LeafMesh's runtime to get audit trails, escalation, observability, and policy enforcement.
If you're prototyping, no — LangGraph alone is fine. If you're going to enterprise production with compliance, governance, multi-vendor, and observability requirements, LeafMesh adds the operational layer that LangGraph doesn't provide.
No. LeafMesh is vendor-agnostic — it runs LangGraph, AutoGen, CrewAI, and custom agents through one fabric. It also adds shared memory, capability-based routing, cost control, and self-healing operations beyond governance.
