Every agent.
One window.

Four agents.
Pick per session.

Every terminal you spawn targets the agent you choose. Mix them across tabs and the grid; a brand mark on every session shows what is running.

$ claude

Claude Code

The quickest start. Session restore, resume by id, and Claude-only flags are first-class.

$ codex

Codex

OpenAI’s coding agent, auto-detected the moment it lands on your PATH.

$ agent

Cursor

The Cursor CLI agent, running in its own native terminal next to the rest.

$ agy

Antigravity

Google’s cloud-backed agent, mixed freely into tabs and grid cells.

Only one agent is required to get started. The rest are auto-detected once installed; Settings shows exactly what is on your PATH.

Built for parallel work.

One sidebar, every session

Session cards are the single switcher: drag to reorder, pin, duplicate, split into the grid, or tear off into a new window. An unread dot tells you the moment an agent needs you.

Up to 8 sessions on screen

A smart grid with selectable layouts and mixable agents per cell. Your manual layout pick sticks until the grid is actually full; arrow keys move focus.

A worktree per session

Spin up a git worktree from the new-session dialog, and choose merge, squash, or discard when the session closes. The branch chip always shows where you are.

Review work hunk by hunk

A verified review cockpit for agent output: stage individual hunks, accept or reject at diff level, and group related changes into changelists.

Setups you save once

Profiles carry a working directory, per-agent arguments, and env vars. They are agent-agnostic: Claude-only flags are stripped automatically when another agent launches.

Close the app, keep the conversation

Sessions are re-attached by id on restart, so a Claude Code conversation survives a reboot. Save a named workspace to restore a whole layout at once.

F1 for everything

A command palette for actions, F2 for session history, and a full keyboard map underneath. Built for people who never touch the mouse.

Native by construction

Tauri and Rust, not Electron. A small signed binary with real PTYs, SQLite storage, desktop notifications, and auto-updates from GitHub releases.

Free. Open source.
Direct from GitHub.

Requires Node.js 22+ and at least one agent CLI installed globally. Claude Code is the quickest start; Codex, Cursor, and Antigravity are auto-detected once on your PATH.

npm i -g @anthropic-ai/claude-code

Builds are not code-signed yet. On macOS, right-click the app then choose Open (or run xattr -dr com.apple.quarantine /Applications/Agentrium.app). On Windows, SmartScreen shows a warning: click More info, then Run anyway. The source is on GitHub.
