T3 Code

T3 Code is a minimal web GUI for coding agents (currently Codex, Claude, Cursor, and OpenCode, more coming soon).

This is a fork of pingdotgg/t3code with a batch of extra features on top — selectable color themes, header usage/spend meters, cross-chat AI restart alerts, a flat "chats by activity" sidebar, per-device feature toggles, and an Android build. See What this fork adds.

Installation

Warning

T3 Code currently supports Codex, Claude, Cursor, and OpenCode. 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 cursor-agent login
OpenCode: install OpenCode and run opencode auth login

Run without installing

npx t3@latest

Tip: Use npx t3@latest --help for the full CLI reference.

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)

yay -S t3code-bin

What this fork adds

Everything below is additive on top of upstream T3 Code. Screenshots are from a live instance.

🎨 Selectable color themes

A color scheme axis that is independent of the light/dark toggle. Pick from Solarized, Dracula, Gruvbox, Catppuccin, and Tokyo Night — each ships a full light and dark variant — or stay on Default. The scheme re-tints the whole app (sidebar, chat, header) and is applied before first paint, so there's no flash, and it syncs across browser tabs.

Set it in Settings → General, right below the light/dark Theme control:

_{Solarized · Light}	_{Solarized · Dark}
_Dracula	_Gruvbox
_Catppuccin	_{Tokyo Night}

📊 Usage, spend & token meters in the header

Keep an eye on how much you're burning without leaving the chat. Small chips in the top bar always show the thread's token usage and your Claude plan usage; a bar-chart menu lets you switch on larger, color-coded readouts per device: Context window, Spend estimate, Claude Session %, Claude Weekly %, and Codex subscription %. Hovering a usage tile shows a countdown to when that limit window resets.

The Codex meter reads your Codex CLI subscription's rate-limit usage passively from local rollout files — no extra API calls — so it even reflects out-of-band codex exec runs. Toggle any stat from the header menu:

🔁 Cross-chat AI restart alerts

When an agent asks you to restart the service it's working on, T3 Code surfaces it so your other chats on the same project don't stomp on the restart. The requesting chat gets a banner with a Mark resolved action, its sidebar row shows a Restart Requested pill, and sibling chats get a "hold" banner. It auto-clears when you reply in the requesting chat.

🗂️ "Chats by activity" sidebar

Flip the sidebar from the grouped project tree into a single flat list of every chat, ordered by last activity, with each row tagged by its project. The choice persists per device.

⚙️ Per-device feature toggles

A Settings → Features page with auto/show/hide toggles for the chat header's action controls — Git actions, Open in editor, and Project scripts. "Auto" shows them on desktop and hides them on mobile-width screens. Stored per device.

And more

Resumable Claude Code conversation import — t3 import claude <session> turns an existing Claude Code transcript into a resumable T3 thread, forking to a new transcript so your original session is untouched.
Android app — a full native Android build (Ghostty terminal, Shiki-highlighted code blocks, themed native chrome, self-signed-TLS trust, sideload APK publish script).
File explorer collapsed by default, and a fix so the left edge of message lines is selectable.

Some notes

We are very very early in this project. Expect bugs.

📊 Usage, spend & token meters in the header

Keep an eye on how much you're burning without leaving the chat. Small chips in the top bar always show the thread's token usage and your Claude plan usage; a bar-chart menu lets you switch on larger, color-coded readouts per device: Context window, Spend estimate, Claude Session %, Claude Weekly %, and Codex subscription %. Hovering a usage tile shows a countdown to when that limit window resets.

The Codex meter reads your Codex CLI subscription's rate-limit usage passively from local rollout files — no extra API calls — so it even reflects out-of-band codex exec runs. Toggle any stat from the header menu:

🔁 Cross-chat AI restart alerts

When an agent asks you to restart the service it's working on, T3 Code surfaces it so your other chats on the same project don't stomp on the restart. The requesting chat gets a banner with a Mark resolved action, its sidebar row shows a Restart Requested pill, and sibling chats get a "hold" banner. It auto-clears when you reply in the requesting chat.

🗂️ "Chats by activity" sidebar

Flip the sidebar from the grouped project tree into a single flat list of every chat, ordered by last activity, with each row tagged by its project. The choice persists per device.

⚙️ Per-device feature toggles

A Settings → Features page with auto/show/hide toggles for the chat header's action controls — Git actions, Open in editor, and Project scripts. "Auto" shows them on desktop and hides them on mobile-width screens. Stored per device.

And more

Resumable Claude Code conversation import — t3 import claude <session> turns an existing Claude Code transcript into a resumable T3 thread, forking to a new transcript so your original session is untouched.
Android app — a full native Android build (Ghostty terminal, Shiki-highlighted code blocks, themed native chrome, self-signed-TLS trust, sideload APK publish script).
File explorer collapsed by default, and a fix so the left edge of message lines is selectable.

Some notes

We are very very early in this project. Expect bugs.
