Local-first AI agent platform — v0.3.8 beta
Your agents.
Your machine.
Your control.
NodeBrain is an open-source platform for building, scheduling, and monitoring AI agents — create a single agent or a full team in one prompt. Local-first and no telemetry: your agents and data stay on your machine, and you choose where inference runs (cloud or fully local).

The system
Agents, connected — locally.
What's inside
A complete agent runtime — without the cloud.
Natural Language Scheduling
Prompts like "Every morning at 9am" is a real schedule trigger. No cron syntax needed.
RAG Memory
Every agent remembers context across tasks using local vector embeddings. No API calls, no cost.
Approval Mode
Agents pause before destructive actions and wait for your go-ahead. Per-agent toggle.
Dry-Run Mode
Test any agent without real side effects. Write actions are simulated and logged, reads still work.
Analytics & Cost Tracking
Token usage, estimated cost per agent and provider, success rates, daily activity — all visible, all local.
Templates Library
5 curated agent teams ready to install in one click. Export and import your own as JSON.
Quickstart
Three steps to your first agent.
NodeBrain installs as a single Windows app. The setup wizard walks you through on first launch.
