Tucano runs several coding agents side by side on your own computer

A developer who already pays for Claude Code or Codex can now run both in one window. The desktop app is Tucano. The author is eduwxyz. It is Apache-2.0 open source. The repository went up on 28 October. It has 121 stars, 24 forks and 23 open issues on 2 November. That is four and a half days later.

What it does

The window looks like a team chat. Each channel has agents in it. Each agent has a name, a role, memory and tools. You mention one with @, or you let the router pick who answers. Agents can hand work to each other. One finds the bug. Another writes the fix. A third reviews it. Every step shows up in the conversation.

Each agent uses one coding tool you already have signed in. Claude Code works with a Pro or Max plan. Codex works with a ChatGPT plan. OpenCode and Pi are the other two. The author says Tucano never sees the password. It reads only two settings from your Claude install. Codex runs with a home of its own, so your personal rules do not leak into a run.

What waits for your yes

Per-tool permission is the new piece. Each agent sees only the tools you give it. For each tool you set no access, read, or read and write. Any call that changes the world stops and asks you first. That is a merge, a purchase, a post, an email, a delete. You see the exact call before you say yes. Approvals can also reach your phone over Telegram. A Pause everything button stops every agent at once.

Each agent has a monthly token limit and a per-reply ceiling. The app shows what the week's work cost in tokens and in replies.

Where the agents live

An agent can run in an isolated Linux in Docker. It can run on your computer directly. It can also run in a browser of its own. That browser is a Chrome window you can watch and take over. On macOS, Windows and Linux, an agent can also use your installed apps. That part runs on agent-desktop, Vercel Labs' open source library.

Tucano speaks the Model Context Protocol. Adding Jira, GitLab, Linear, Figma, Notion, Datadog or a company's internal server is one entry on the Connectors page. Routines run work on a calendar, or when a new issue, a failing monitor or an email shows up.

Code review turns into the slow step once writing code is cheap. This app gives the review step its own agent. That agent has its own tools and its own ceiling on what it can do without asking.
