Que pouvez-vous faire avec Behavior Trees ?

  • Custom nodes: create your own node types in any of the four basic categories — composite, decorator, action, or condition
  • Node properties: edit titles, descriptions, and custom properties per node instance
  • Manual and auto layout: drag nodes around, or press a to auto-organize the whole tree
  • Multiple trees per project: create and manage as many trees as you need
  • JSON import/export: an open format that works with any behavior3-compatible runtime
  • No lock-in: runs in the browser, no accounts, no external tools or engines required

Installation

Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http behavior-trees 'https://www.behaviortrees.com/mcp'

Behavior Trees Editor

A free, open-source visual editor for behavior trees, live at behaviortrees.com. Model AI for games, robotics, and simulations, then export to an open JSON format you can load with any behavior3-compatible library.

Originally based on behavior3editor by Renato de Pontes Pereira, since rebuilt as a modern React editor on the Nocturne design system and extended with a guides site. The original AngularJS editor lives on at old.behaviortrees.com.

What's in this repo

A pnpm + Turborepo monorepo:

PathWhat it isWhere it deploys
apps/editor/Main editor (React + TypeScript + React Flow)behaviortrees.com
apps/editor-classic/Classic editor (AngularJS + gulp)old.behaviortrees.com
apps/site/Guides and articles (Astro)behaviortrees.com/learn
packages/examples/Shared example trees consumed by both editorsbundled into both editors

apps/editor-classic is intentionally not a workspace member — its gulp 3 toolchain keeps its own npm lockfile. Never run pnpm inside it.

Features

  • Custom nodes: create your own node types in any of the four basic categories — composite, decorator, action, or condition
  • Node properties: edit titles, descriptions, and custom properties per node instance
  • Manual and auto layout: drag nodes around, or press a to auto-organize the whole tree
  • Multiple trees per project: create and manage as many trees as you need
  • JSON import/export: an open format that works with any behavior3-compatible runtime
  • No lock-in: runs in the browser, no accounts, no external tools or engines required

Development

git clone https://github.com/behaviortrees/behaviortrees.git
cd behaviortrees
pnpm install

pnpm dev --filter @behaviortrees/editor   # React editor (Vite)
pnpm dev --filter @behaviortrees/site     # guides site (Astro)
pnpm build                                # build editor + site via Turborepo
pnpm test                                 # editor test suite
Classic editor

Uses Node <= 22 (see .nvmrc) and its own npm toolchain:

pnpm build:classic          # npm install + bower install + gulp build, from the repo root
# or, inside apps/editor-classic:
npm install --ignore-scripts
npx bower install
gulp serve                  # live reload at http://127.0.0.1:8000

Deployment

The React editor deploys to behaviortrees.com through apps/editor/vercel.json (Vercel root directory: apps/editor); its build also bundles the guides site so /learn is served from the same deploy. build-deploy.sh builds the classic editor and the guides site, merging both into deploy/ as the static site Netlify serves at old.behaviortrees.com (via netlify.toml).

License

  • The classic editor and repo root are MIT — see LICENSE, © 2014 Renato de Pontes Pereira.
  • The React editor (apps/editor/) is AGPL-3.0 © Alan Hoskins, with portions derived from the MIT original — see apps/editor/LICENSE and apps/editor/LICENSE-MIT.
