esveo code

esveo's fork of T3 Code, the agent harness for Claude Code, Codex and more.

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

Getting started

Setting up the app, the server and your clients is described in docs/fork/setup.md.

Features

Warning

esveo code currently supports Codex, Claude, Cursor, Grok Build, OpenCode, Antigravity, and fx. 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.
• fx: install fx and run fx login on the machine running the esveo code server (setup guide)

Split view

Drag a thread next to the one you have open.

Git graph

The repository's commit graph in the side panel. Click a commit to see its diff, or ⌘-click a second one to diff the range.

Context, cost and cache

The composer shows context usage, the thread's cost and how long the prompt cache stays warm.

Subagent chats

Every subagent opens as its own thread, live while it runs. From there you can send it a message through the main agent, and stop a Claude subagent.

Thread orchestration

A coordinator thread starts child threads, waits for them and collects their results. Existing threads can be moved under a coordinator, to another one, or released again. To let it start and reach threads in other projects too, turn on Cross-project threads in Settings → Threads.

Agent stage

Watch every agent move between thinking, reading, editing, terminal and subagents.

Thought trail

Read back the thinking behind any answer.

Voice calls

Talk to the open thread instead of typing. GPT-Live holds the conversation on your Codex ChatGPT login, hands the work to the thread's agent and reads the result back. Turn it on under Settings → Voice → Voice calls; while it is off, nothing of it runs and agents don't get its voice_say tool.

esveo themes

esveo and esveo Midnight, each in light and dark.

And more

• A Notes tab in the right panel for notes and todos per thread, per project and globally: capture with ⌥⌘K, drag to sort or tick off, and insert a note into the composer in one click.
• Notion pages in the right panel: a Notion link in the chat opens the page read-only, with its properties, content and relations, once a Notion integration secret is stored under Settings → Source Control.
• An Instructions tab in the right panel to read and edit the CLAUDE.md or AGENTS.md your Claude or Codex agent reads, for the thread's checkout or globally.
• Runs on upstream's Orchestrator V2 ahead of upstream's own release: fork a thread from any answer, switch provider mid-thread, attach threads as context, scheduled tasks, and usage limits that resume by themselves. Your chats are backed up before the one-time move to it.
• Threads, subagents and workflows survive a server restart.
• Two-line thread cards, grouped by project.
• Prompts lost to an early interrupt carry over to the next turn.
