Markr

Canonical version: Markr.

Markr is a tiny desktop timer that lets you bookmark moments while you record, so editing means jumping to marks instead of scrubbing the whole clip. Mark the moment as it happens, not after. Electron/React/TypeScript, MIT.

The workflow it fixes: you record a video or stream, something good happens, and later you waste time scrubbing back and forth hunting for it. Markr drops a timestamp the instant it happens, even with the app in the background, so the highlights are already located before you open the editor.

How it works

• Session timer. Start to zero the elapsed clock; the running time is what marks are stamped against.
• Mark button + global hotkey. Cmd+M (macOS) or Ctrl+M (Windows/Linux) logs a timestamp in mm:ss, and the hotkey fires even when Markr isn't focused, so you never break recording flow.
• In-memory, no accounts. No database, no login; stopping freezes the timer and keeps the marks for review; a new session resets.

Deliberately minimal: Electron with React, electron-vite, Tailwind v4, and shadcn/ui; global hotkeys via Electron's globalShortcut. Prebuilt installers for macOS, Windows, and Linux (unsigned, so you confirm the first-launch security prompt).

It pairs with a recorder like OBS Studio: OBS captures, Markr indexes the moments worth keeping.
