One app to manage
all your AI agents
Terminal-centric project manager where each task gets its own git worktree, tmux session, and full terminal — all orchestrated from a Kanban board.
dev-3.0
Terminal-centric project manager where each task gets its own git worktree, tmux session, and full terminal — all orchestrated from a Kanban board.
You're running 5+ agents across different terminals, repos, and branches. Switching context takes forever. You lose track of what's where.
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.
When you start a task, dev-3.0 creates a fresh git worktree. Every agent works in its own copy of the repo — zero conflicts, full isolation. Your setup script runs automatically.
Click any task to enter its terminal — powered by Ghostty's rendering engine with tmux preconfigured. Split panes, scroll history, copy-paste — everything you expect from a real terminal. AI agents run natively, with all their 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.
Run the same task with different agents or configs. Compare approaches side-by-side and pick the best result.
Configure a setup script per project. Install deps, seed data, start services — runs automatically for each new task.
dev-3.0 is a native desktop app. Download the DMG, drag to Applications, and you're ready. No build steps, no dependencies, no configuration.
