Ledgerline Stack — the dev stack in your menu bar

A macOS app that replaced the team’s terminal menu: start, update, seed and watch the whole local stack with buttons, and see its health right in the menu bar.

Ledgerline Stack popover under its menu-bar dot: a green ECG heartbeat line reading 3/3 services up, four services with uptime strips, and Quick start, Start all, Update all and Kill all buttons

problem: Running four services locally meant a terminal menu, tmux panes and remembered commands — and when a service died, nobody noticed until something broke.
built: The whole tool, solo (111 of 112 commits): a CLI for machines with a typed JSON/NDJSON contract; a loopback HTTP server with token auth, a single job lock and SSE; a React UI that works in any browser tab; an Electron shell with “Rebuild & relaunch” (atomic swap and rollback), a menu-bar status dot, notifications and a popover with an ECG-style heartbeat and six tabs — Stack, Jobs, Watcher, Caffeine, Git, Settings. A watcher daemon restarts failed services. A demo mode over a made-up stack made the promo video possible without real data.
result: 111 / 112commits — built solo6popover tabs over one CLI contract

Brand name changed under NDA — the work and the numbers are real.

Ledgerline Stack main window: the Core service selected — healthy, its branch, port and tmux session — with its live logs streaming, and a sidebar of stack actions, apps and tools

The Jobs tab of the Ledgerline Stack popover: duration bars of the recent runs, with a failed run in red unfolded to show the step that broke
