feat(providers): add DeepSeek Harness (dsh) as a provider
DeepSeek Harness could not be selected in T3 Code, so there was no way to
run DeepSeek models on an environment alongside the existing providers.

Add a DSH driver with its ACP support and text generation, register it in
the built-in driver list and model manifest, and wire it through the web
and mobile model pickers, provider icons, settings metadata, and provider
compatibility checks. Also let the packaged desktop renderer origins
(t3code://app) through the web dev server's CORS preflight.

T3 Code

T3 Code is an "agent harness control surface". It enables control of the agents on your machine with a best-in-class mobile app (iOS, Android), web app and Electron-based desktop app.

Works with your subscriptions on Claude Code, Codex, Cursor, Grok Build, OpenCode, and Google Antigravity. If they're set up on your computer, T3 Code can control them.

"Wait, what are you selling me?"

Nothing. We built T3 Code because we wanted the best possible development experience with agents. We were inspired by existing solutions like the Codex desktop app, Conductor, Claude Desktop and Cursor Glass, but none met our bar.

We wanted something performant, remote-ready, and truly open. If we ever go the wrong direction, we want you to have everything you need to fork and build the editor that you want.

Installation

Warning

T3 Code currently supports Codex, Claude, Cursor, Grok Build, OpenCode, and Antigravity. Install and authenticate at least one provider before use:

  • Codex: install Codex CLI and run codex login
  • Claude: install Claude Code and run claude auth login
  • Cursor: install Cursor CLI and run agent login
  • Grok Build: install Grok Build CLI and run grok login
  • OpenCode: install OpenCode and run opencode auth login
  • Antigravity: enable it in Settings, then use Install Antigravity and Sign in with Google. No CLI is required.

Command line

curl -fsSL https://t3.codes/install.sh | sh

On Windows, in PowerShell:

irm https://t3.codes/install.ps1 | iex

Then run t3 to start the server and open the local web app. t3 service install keeps it running in the background, t3 update moves to a newer release, and t3 --help has the full reference.

To try it once without installing, run npx t3@latest instead.

Desktop app

Install the latest version of the desktop app from GitHub Releases, or from your favorite package registry:

Windows (winget)

winget install T3Tools.T3Code

macOS (Homebrew)

brew install --cask t3-code

Arch Linux (AUR)

Stable:

yay -S t3code-bin

Nightly:

yay -S t3code-nightly-bin

The AUR packaging is maintained in this repository under packaging/aur.
