The AI coding agent
that runs on your computer.
Liminal AI fixes bugs, refactors code, runs tests, researches the web, and remembers what worked — using 140+ tools and the LLM you already pay for. Free, open source, install in under two minutes.
Liminal — the space between what you want built and what the machine actually does. We built the harness that closes that gap: plan, act, verify, remember.
Everything a serious coding agent needs — out of the box.
From reading your repo to shipping a fix. No plugins required for core developer workflows.
Finishes multi-step tasks
Plans, executes tools, recovers from errors, and compresses context so long sessions keep working — not just one-shot answers.
140+ developer tools
Files, terminal, git, tests, lint, web search, browser automation, code intelligence, docs to PDF/PPTX — activated on demand so the agent stays focused.
Remembers across sessions
Saves facts, lessons, and winning workflows locally. Optional Obsidian vault. Gets sharper the more you use it.
Parallel sub-agents
Spin up helpers for big refactors or research. Parent agent merges results. You stay in control with approvals on risky commands.
Custom assistant personality
First-run setup builds voice, tone, and a themed UI — so it feels like your teammate, not a generic bot.
Smart model routing
Strong model for hard steps; fast cheap model for background work. Typical tasks cost pennies on OpenRouter.
You're in control
Shell and destructive actions ask permission first. See every file change before it lands. Optional auto-approve only on machines you trust.
Live visibility
Watch tools run in real time in terminal or browser. No hidden "thinking" black box.
Learns from wins
Successful patterns are saved and suggested on similar tasks later — compounding productivity.
One command. Working agent. No SaaS signup.
The installer clones Liminal, sets up your API key, builds the app, and opens the web UI.

Built for developers, founders, and power users.
Ship features faster
Delegate refactors, test fixes, and repo exploration while you review diffs. Works in your existing project — not a sandbox demo.
One tool, many models
Swap DeepSeek, Claude, or GPT without changing tools. Pay per use. No monthly seat fee to us.
Keep code on your network
Run on a dev machine or internal server. Audit JSONL session logs. Enterprise support available from Vireon Dynamics.
FAQ
Liminal AI questions
What is Liminal AI?
Liminal AI is a free, open-source AI coding agent that runs on your computer. You describe a task in plain English; the agent plans steps, uses tools (read files, edit code, run terminal commands, search the web), and shows you everything it does. It's built for real software work, not casual chat.
Is Liminal AI free?
Yes. The software is MIT licensed — $0 forever. You only pay your AI provider (OpenRouter, OpenAI, etc.) for model usage, typically a few cents per task with efficient routing.
How is Liminal different from ChatGPT or Cursor?
ChatGPT is a conversation. Cursor is an editor with AI built in. Liminal is a full agent loop: it executes tools on your machine, keeps persistent memory, supports sub-agents, and works in terminal or browser UI. You choose any compatible model and own the session logs.
Does Liminal work on Windows, Mac, and Linux?
Yes. Install with one command on macOS, Linux, WSL, or Windows PowerShell. Requires Node.js 22+ and an API key from any OpenAI-compatible provider.
Is my code sent to Vireon Dynamics?
No. Liminal runs locally. Your messages and code go to the model provider you configure (e.g. OpenRouter). We don't host your sessions or train on your data.
What models does Liminal support?
Any model behind an OpenAI-compatible API: DeepSeek, GPT, Claude (via compatible endpoints), Gemini routes on OpenRouter, or fully local models through LM Studio or Ollama.
