Think iTerm2 meets Kanban meets tmux. A next-gen terminal with built-in task management for any shell-based AI coding agent. No opinionated workflows, no magic — just proper infrastructure for running N agents at once.
You're running 5+ agents across different terminals, repos, and branches. Switching context takes forever. You lose track of what’s where. We tried every tool in the space — each had cool ideas, but something was always missing. So we built our own.
Dozens of terminal tabs, each running a different agent in a different branch. Finding the right one is a nightmare.
Every time you switch between agents, you waste minutes remembering where you left off and what each one is doing.
Multiple agents editing the same repo. Constant merge conflicts. No isolation between parallel workstreams.
Projects, tasks, and terminals — each layer gives you more control over your AI-powered workflow.
Create tasks, drag them between columns, and see at a glance what every agent is doing. Each task is a unit of work — a feature, a bugfix, a refactor. You stay in control of the big picture.
Every task on the board gets its own isolated git worktree. Inside that worktree you can run as many agents as you want — in parallel, same codebase, without stepping on each other’s toes. Claude, Cursor, Codex, Gemini — all at once on the same task if needed.
Each task opens a real terminal powered by Ghostty’s rendering engine with tmux preconfigured. Split panes to run several agents side by side in the same worktree — Claude, Gemini, Codex, whatever you need. Scroll history, copy-paste, all native features intact.
Every feature is designed around one goal: managing many AI agents across many tasks without losing your mind.
Hover over any task card on the Kanban board to see a live preview of its terminal — without switching views. Instantly check what each agent is doing. The preview updates in real-time, every second.
Full repo isolation. No merge conflicts between parallel agents. Each task works on its own branch and copy.
Each task launches with tmux and your preferred command. Split panes, persistent sessions, full terminal power.
Agents send a bell when they need your attention. Red badges appear on task cards so you never miss a prompt.
Move tasks between status columns with drag-and-drop. Visual feedback, smooth animations, intuitive flow.
Organize tasks with colored labels (Bug, Feature, Refactor…) and find anything instantly with full-text search. Create tasks from remote branches — just paste a branch name, hit Fetch, and the agent starts working on it.
Don’t know exactly how something should look? Run the same task 3, 5, or 10 times — with different agents, models, or prompts. Each attempt gets its own isolated worktree. Browse the results, keep the winner, delete the rest.
Check out any remote branch and toggle “PR review” to pre-fill a structured code-review prompt. The agent reviews — not modifies — the code.
Configure a setup script per project. Install deps, seed data, start services — runs automatically for each new task.
Launch your app straight from the task’s worktree with a single click. Restart or stop instantly — no terminal juggling. Configure the dev command per project and every task gets its own isolated server, ready in seconds.
Define your own pipeline: AI Review, PR Review, On Hold — whatever stages your team needs. Move tasks through your custom flow with a click.
Full theme support. Switch between dark and light modes to match your environment and preference.
Clone node_modules, .venv, and other heavy directories into worktrees instantly with near-zero disk usage. Auto-detect finds well-known paths across 12+ ecosystems.

Built on a native webview runtime, GPU-accelerated terminal, and the fastest JS runtime available. Instant startup, minimal memory footprint, and a silky-smooth experience.
Native macOS webview runtime. Lightweight, fast startup, tiny memory footprint.
All-in-one JS runtime. Fast installs, native APIs, built-in bundling. Main process runs in Bun.
GPU-accelerated terminal rendering engine. Buttery smooth, true-color, fast as native.
Battle-tested terminal multiplexer. Persistent sessions, split panes, keyboard-driven workflow.
dev-3.0 doesn’t integrate with agents — it hosts them. Any tool that runs in a terminal works out of the box. When agents ship new features — like Claude’s multi-agent teams — you get them instantly, no update needed.
