The self-orchestrating control plane for coding agents.
Up.computer brings the agent CLIs you already use into one free, open-source desktop app. Talk an idea through in a chat and it becomes a task that a worker agent picks up in the background, on Codex, Claude Code, Cursor, Grok Build, OpenCode, Antigravity, Pi, or an agent from the ACP Registry. Each agent runs on your own subscription, and every chat stays on your computer.
Bug reports and focused feedback are welcome. Large feature work should start with an issue before a pull request.
Download the app from up.computer/download or the latest release. Builds are published for macOS (Apple Silicon and Intel), Windows, and Linux, straight from this repository. The macOS builds are signed and notarized. The Windows installer is not signed yet, so SmartScreen shows a warning on first launch. Installed apps update themselves from GitHub releases.
Up.computer runs the coding agents you install. Set up any you want to use:
- Codex: connect with ChatGPT in Settings → Providers, or install the
Codex CLI and run
codex login. - Claude Code: install Claude Code
and run
claude auth login. - Cursor: sign in from Settings → Providers → Cursor, or set
CURSOR_API_KEY. No Cursor CLI is needed. - Grok Build: install the Grok Build CLI and run
grok login. - OpenCode: install OpenCode and run
opencode auth login. - Antigravity: install it and sign in with Google from its provider settings. No CLI is needed.
- Pi: install Pi and run
pionce to finish its login or API-key setup. - Other agents: choose Add provider in Settings → Providers to add an agent from the ACP Registry or a local ACP command.
Codex an 914F d Claude are on by default. Cursor, Grok, OpenCode, Antigravity, and Pi are off by default; turn them on in Settings → Providers when you want to use them.
Package-manager installs such as Homebrew, winget, and AUR are not an official install path yet.
Requirements:
- Vite+
vp - Node 24.13.1+
- Git
- At least one supported coding agent, installed and authenticated
Install Vite+:
curl -fsSL https://vite.plus | bashInstall dependencies and run the app:
vp install
vp run devUseful development commands:
vp run dev:web
vp run dev:server
vp run dev:desktop
vp run dev:marketingSee the development runbook for worktrees, ports, and test data.
- Run multiple coding agents from one desktop GUI.
- Keep agent work grouped into project threads instead of scattered terminal sessions.
- Review changed files and diffs before trusting or shipping a run.
- Commit, push, publish repositories, and open pull requests from the app.
- Track work as tasks, let saved task agents pick them up by status and tag, and create tasks on a schedule.
- Give every agent a managed browser and native desktop observation and control.
- Work against local projects with the desktop app's built-in backend, and pair a browser or another desktop app with it over your local network or Tailscale.

Up.computer is built as a fork of the open-source T3 Code project:
https://github.com/pingdotgg/t3code
This fork keeps the upstream runtime, provider orchestration, contracts, desktop infrastructure, and release plumbing close to upstream while developing a different product direction, UI, branding, and workflow layer.
Internal identifiers keep their T3 Code names so upstream merges stay cheap and upstream clients
stay compatible: the @t3tools/* package scope, T3CODE_* environment variables, the t3 CLI
name, and the pairing protocol. The application identity, protocol links, updates, and data
directories use Up.computer names. See docs/branding.md.
The project is early and the architecture is still settling. Small, focused bug fixes, reliability improvements, performance improvements, and clear docs fixes are the easiest contributions to review.
If you want to make a non-trivial product, UI, or architecture change, open an issue first so scope can be discussed before you spend time on a large branch.
