Atomic Agent

What is Atomic Agent?

Atomic Agent is an open-source AI agent runtime that runs on your own computer. It serves a small quantized model through llama.cpp, then loops on a task: the model returns a list of tool calls, the runtime executes them, stores the results in a local SQLite state, and asks again until the job is done. Tools cover a real browser, files, shell commands, git and document reading, and risky actions such as shell, file writes and HTTP pause for your approval. Interfaces include a desktop app, a text-based terminal interface, a command-line client, an HTTP API that follows the OpenAI format, and chat apps like Telegram and Discord, and it connects to external tools over the Model Context Protocol. Cloud models are optional. It is made by AtomicBot and released under the MIT license as a developer preview, so commands and config still change between versions. The software is free, local models carry no token bill, and the only cost is the electricity and hardware you already own.

Use cases

• Run an AI agent offline on your own machine
• Sort and rename files with an AI assistant
• Triage a repo issue and open a fix on a branch
• Schedule recurring checks with Telegram alerts
• Research sources in a browser and save cited notes
• Embed a local agent in another app over HTTP

Who it's for

• Developers
• Privacy-conscious users
• Local LLM enthusiasts
• Teams with air-gapped workflows

Why use Atomic Agent

• Keep files, sessions and memory on your own machine by default, which suits private or air-gapped work.
• Avoid per-token bills when you run a local model, since the only metered cost is your own hardware.
• Stay in control of risky steps, because shell commands, file writes and HTTP calls wait for approval.
• Extend it with MCP servers, skills and swappable models instead of waiting on a vendor roadmap.
• Start from a desktop app with no terminal, or install by command line and script it.

Atomic Agent features

• Local inference through llama.cpp with a default qwen-3.5-4b model
• Grammar-constrained (GBNF) decoding that keeps tool calls structurally valid
• Tools for browser, filesystem, shell, git, documents and vision
• Approval gates before shell commands, file writes and HTTP requests
• SQLite-backed memory, sessions and tasks stored on your disk
• Scheduling with cron, intervals and webhooks
• Model Context Protocol (MCP) support and reusable skills
• Terminal UI, CLI, OpenAI-compatible HTTP API, Telegram and Discord control
• Cloud models via any OpenAI-compatible endpoint, when you opt in

How to get started with Atomic Agent

1. Download the desktop app for macOS, Windows or Linux, or install from the terminal with the curl installer.
2. Let it download a local model through llama.cpp, or point it at your own llama-server or a cloud endpoint.
3. Give it a task in plain words from the desktop app, terminal or Telegram.
4. The model returns a batch of tool calls; the runtime runs them, pausing for your approval on risky ones.
5. Results are folded into SQLite state and the loop repeats until the agent replies or you stop it.

Atomic Agent limitations

• Developer preview: commands, config and behavior are still changing
• No Intel Mac build; macOS support is Apple Silicon only
• Anonymous usage stats and crash reports are enabled by default; turn them off in config.json
• Quality depends on the local model you can fit in your GPU memory or RAM

Atomic Agent pricing
