ReplayMac
A menu bar app for macOS 15+
The best clips happen while you're not recording.
ReplayMac quietly keeps the last few minutes of your screen and audio in memory. When something worth keeping happens — a boss kill, a bug you can't reproduce, a moment — press one hotkey and save it. After the fact.

In practice
Leave it running
A badge in the menu bar shows it's buffering — 15 seconds to 5 minutes in memory, or up to 30 minutes rolled to disk. Set it to launch at login and forget it exists.
The moment happens
You weren't recording. Nobody ever is. There's no scramble for a record button, because the recording already exists.
Press the hotkey
A normal MP4 lands in ~/Movies/ReplayMac/. No project files, no editor, no upload. Trim it, tag it, or turn it into a GIF in the built-in library — if you feel like it.
↑ the whole app lives here. saved badge, buffered time, one click to the last clip.
I occasionally game on my Mac, and I miss the feature on my PS5 that lets me easily save clips from the past few minutes. ReplayMac essentially recreates this for me. Good work.

Free and source-available. Built by one person — if it saves your moment, a coffee is appreciated.
Honest small print: GitHub builds are notarized and open like any other app — they just don't update themselves. Grab new releases from GitHub when you feel like upgrading. The Mac App Store version, once it lands, will handle updates for you.
