Open Source — Apache 2.0

Your AI agent.
One server. Any device.
No baked-in behavior.

A coding assistant, a research agent, a personal automation — same binary, different configuration. Your code. Your keys. Your agent.

The agent does what you tell it to

No baked-in behavior. No hidden prompts. No fixed tools. Install with one command, connect your LLMs, and the agent runs on your server.

Any LLM

Connect any LLM. Switch per-session. No vendor lock-in. Budget models for routine tasks, premium models for hard problems.

Tools in Any Language

Write tools in any language. Drop them in. The agent picks them up. A tool is just a script that speaks JSON on stdin/stdout — Rust, Python, Bash, Go, anything.

MCP & Skills

Connect any MCP server for external tooling, and define Skills as discoverable instruction sets. Both are automatically available to your agent.

Subagent Orchestration

Agents can spawn subagents for complex tasks — isolated sessions that inherit your workspace context. Interrupts cascade automatically.

Access From Anywhere

One persistent server on your machine. REST API and WebSocket under the hood. Desktop, mobile, or browser — all connect to the same agent. Works over Tailscale, VPN, or your local network.

Make It Yours

Download preset bundles for coding, research, or ops. Or build from nothing — define the system prompt, pick the tools, choose the model. Your agent, your rules.

Give it tools. Give it purpose.

01

AI-Powered Coding

Connect Claude, GPT-4o, or Gemini to your codebase. Subagents explore, refactor, and implement with full workspace isolation.

02

Research & Analysis

Give your agent tools to query APIs, scrape pages, and process documents. Isolated workspaces keep research contexts separate. Sessions compact via LLM summarization to stay focused.

03

Deployment & Ops

Connect MCP servers for Kubernetes, AWS, or Terraform. Tools in Bash or Python interact with your infrastructure. Subagent orchestration handles multi-step deployment pipelines.

04

Automation Workflows

Create agent personalities for repetitive tasks. Skills let agents discover and follow domain-specific instruction sets. Queue sessions for batch processing.

Your code. Your keys. Your agent.

One command to install. One command to start. Open source under Apache 2.0. No baked-in behavior. No vendor lock-in.
