A private home for AI coding.
CodeHearth runs capable coding models directly on your Mac. No cloud, no accounts, no setup gauntlet. Just an agent that reads, edits, and runs your project while your code stays on your machine.

Built to keep things close to home
Everything you need to pair with an AI on real code, without sending that code anywhere.
Runs on your Mac
On-device inference with Apple's MLX. Your files and prompts never leave the machine. There's no server to call.
Edits with guardrails
The agent reads, writes, and runs commands, but you approve anything that touches files or your system. Reads can be automatic; changes are yours to confirm.
Review every change
Proposed edits land as clear diffs in the workspace. Accept or reject inline. CodeHearth is git-aware, so you always know your branch and status.
Bring your own models
Use the built-in on-device models, or point CodeHearth at a model server you already run on your machine or network.
Sessions that persist
Pick up where you left off. Past sessions reopen with their full transcript and context intact.
Reads your screenshots
Drop in a screenshot of an error or a UI. Vision-capable models can read the image right alongside your prompt.
Three panes. No ceremony.
Files on the left, your workspace and diffs in the middle, the agent on the right.
Open a project
Point CodeHearth at a folder. It indexes the file tree and picks up your git branch automatically.
Pick a model
Choose an on-device coding model, or connect your own server. CodeHearth fits the recommendation to your Mac's memory.
Build together
Describe what you want. Review the diffs, approve the changes you like, and keep moving, all locally.
Private by default, not by setting
CodeHearth was built local-first. There's no account to create and no inference in the cloud. The only time anything leaves your Mac is when you choose to download a model or connect to a server yourself.
- Your code and prompts stay on your machine
- No accounts, no sign-in, no telemetry
- No App Sandbox tricks; it works with your real files and shell
- Optional: connect a local or network model server you control
Light the hearth.
A calm, private place for you and an AI to work on real code. Built for Apple Silicon.
