Build

These pages cover everything you do in the editor: drawing the graph, configuring nodes, wiring state, and reusing work across workflows.

  • The editor

    Panels, canvas editing, undo, clipboard, layout, notes and the command palette.

  • Nodes

    Every node type, its settings, and how it behaves in a run.

  • Agent node

    A model that picks and calls the tools you allow, with rounds and approvals.

  • State and references

    Field types, reducers for parallel branches, {{state.x}} paths and filters.

  • Code mode

    Write main(state) in a Tool node and run it in a sandbox.

  • Knowledge bases

    Upload documents and search them from a Retriever node.

  • MCP servers

    Register Streamable HTTP or stdio servers and call their tools.

  • Workflow templates

    Start from a starter, save your own, export and import them.

  • Versions

    History of every change, diffs and restore.

  • Export to Python

    See the workflow as LangGraph code, and run it on its own.
