Why Mast exists

Your machine runs a web of things.
Mast draws the lines between them.

Every terminal tab knows one piece. lsof sees ports. git status sees branches. docker ps sees containers. Mast correlates all of them into a single live chain.

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.

Every verb, inline

Expand a row and the verbs appear under it. No sub-pages, no context switches. Git operations run with their real commands — git stash push -u, git reset --hard HEAD && git clean -fd.

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.

leonhoulier-site:3000 → vite

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.
