Nexus
Developer Mission Control

Command the swarm,
not the windows.

A desktop command center for AI-assisted engineering. Describe a task, dispatch it to Claude Code or Copilot in an isolated worktree, and review what comes back — across every repo, from one pane. Not an editor. A mission control that sits beside it.

AI agents are fast. Window-juggling is the bottleneck.
✗
Context switching kills flow

Alt-tabbing between terminals, editors, and browser tabs destroys the focus an agent run depends on.

✗
One terminal per agent per repo

Five repos, three agents each — that's fifteen windows you're supposed to track in your head.

✗
You can't review what you can't find

Diffs scattered across worktrees mean changes slip through unreviewed.

Features

Start a run

Describe the task in plain language, pick a provider, and Nexus spins up an isolated worktree and drops you into a live session — reviewing in minutes, not after a manual branch dance.

Project Rail

Switch repos in one click. Every entry shows live git state — current branch, dirty file count, worktree count, and how many agents are running — so the whole fleet is legible at a glance.

Live telemetry

Agent status is parsed straight from terminal output — no API calls, no polling endpoints. Model, live/idle state, elapsed time, and CPU surface in the rail and status bar.

Code Review

Move through an agent's changed files hunk by hunk. Approve & Next keeps you in flow; J K A R S N drives the queue without leaving the keyboard.
