Components

• gateway/router/ — Node.js webhook router. Reads user ID from incoming messages, assigns to least-loaded OpenClaw instance via Redis.
• extensions/auth-gate/ — Channel-level allowlist. Blocks unregistered users before LLM runs. Zero cost for freeloaders.
• extensions/rule-injector/ — Per-user identity, rules, and health data injection. The brain of multi-tenant personalization.
• hooks/user-bootstrap/ — Creates per-user workspace (USER.md, MEMORY.md) on first message.
• server/ — Companion API server. Auth, registration, channel linking, health data.
• templates/ — Companion personality templates. Swap SOUL.md + AGENTS.md + rule-injector templates to create a new companion product.
• docker/ — Docker Compose for full platform deployment.
• scripts/ — Instance lifecycle, cron wrappers.

Creating a New Companion

cp -r templates/companion templates/my-new-companion
# Edit templates/my-new-companion/.openclaw/workspace/SOUL.md
# Edit templates/my-new-companion/.openclaw/workspace/AGENTS.md
# Update rule-injector templates for your domain
# Deploy with: docker compose up --scale openclaw=3

Scaling

• Each OpenClaw instance handles ~500 concurrent users
• Router auto-assigns new users to least-loaded instance
• Add capacity: docker compose up --scale openclaw=N
• Redis handles user→instance mapping and state coordination
• Supports 1M+ users with enough instances
