ffmpeg exists, if you don't like it and can't use (don't want to learn) the shell and ffmpegs commands, there is OBS with all those features and more. I don't see the usecase.

FFmpeg and OBS are extremely powerful tools, but they require local installation, CLI knowledge, and manual configuration. Showesome is a Chrome extension that records screen, tab, or camera entirely in-browser, with built-in zoom/highlight effects. Lightweight, zero-install, and free — ideal for quick demos or tutorials without extra setup.

Every demo video I see now has the zoom effect that seems to have been popularized by https://screen.studio. Screen studio is $29/month.

The OP's software appears to be similar but free. There is definitely a use case for this.

Yearly licenses are 9$/month, so a lot cheaper if you use it on a regular basis. Not affiliated.

Sounds neat, but I'm not installing a screen recorder browser extension that's not open source…

Fair point. I’m not open-sourcing it, but it doesn’t collect or send any data — everything runs locally.

Not sure about other folks, but I'd never trust a privacy-friendly tag on an indie software that's not open-source. Even for popular and trusted software (e.g., Obsidian) it gives me chills.

Totally get it — open source definitely helps build trust. That said, getting the Chrome Web Store Featured Badge means the extension passed their strict review, including privacy rules.

Privacy and Chrome are incompatible with one another.

Fair take. Everyone has different privacy thresholds, and that’s totally fine. Just sharing the tool for those who find it useful.
