Why Mast exists

The web developer's
favourite menu bar.

Watch your git. See what's on localhost. Pick up exactly where you left off. Hand the repo to Claude Code, Codex, or Cursor. All one click from the menu bar, all day.

01
Monitor your git
Every repo's branch, upstream, dirty count, ahead / behind, PR count — live. No git status loop.
02
See localhost
Every listening port mapped to the repo that owns it. Open :3000 pill, one click, browser tab.
03
Pick up where you left off
Your last branch, last commit, last dirty files — already on screen the second you click the tray icon.
04
Open in Claude
Or Codex or Cursor. Sparkles button opens the repo in your AI agent, already cd'd in.
What's in the menu bar

One list. Every verb.

The popover shows every repo on your machine in one scrollable list — branch, upstream, dirty files, open PRs, and the primary action you'd take next. No tabs, no dashboards, no stat tiles.

The Repos list

Auto-discovered repos in your dev roots. Each row shows the status dot, branch → upstream, time since last commit, open PRs, dirty count, and the action you'd click next — Open :<port> when a dev server is live, Start otherwise.

Status at a glance

The menu bar icon itself is the first signal. Gray is quiet. Green is all clear. Yellow and red earn your attention.

The full git loop, inline

Expand a row and every verb you'd normally type appears under it — grouped into Git, Open, and Info. Destructive actions (Push, Discard, Undo, Amend) arm on first click, fire on the second within 3 s. Real commands, no wrappers.

Pull Fetch Commit Push ↑2 Undo Amend Stash Discard Create PR
Ports, correlated in

Mast watches lsof, maps listening processes back to their cwd, and surfaces the match as an Open :<port> pill on the repo that owns it. No separate ports list to manage.

devdash:8765 → electron-vite
leonhoulier-site:3000 → vite
api-gateway:4100 → express
Hand the repo to your AI agent
NEW

Every repo row has a sparkles button that opens that repo in your configured AI coding agent — Claude Code, Codex, or Cursor — in a fresh Terminal window or the Cursor GUI. One click, already cd'd into the right working directory, ready to prompt. Pick the default on first launch; change it in Settings later.

Companion CLI

Same data. In the terminal.

When your hands are on the keyboard, mast renders the popover as ANSI. Same rows, same dots, same verbs.
