Extension FAQs
Frequently asked questions specifically about the browser extension.
Is it really completely free and local-first?
Yes, 100%. The extension is fully private and local-first. We do not have servers to transmit your screenshots to. All screenshot files, library folders, and annotations reside exclusively inside your browser's sandboxed IndexedDB storage and never leave your machine.
Does the extension show any browser debugger notifications?
No, absolutely not. Unlike legacy tools that require the `debugger` browser API (which shows a persistent banner stating "Supashot is debugging this browser"), Supashot uses standard sandboxed visible-tab capture and offscreen stream decoding fallbacks. You will never see annoying debugger warnings.
Does it support Arc, Brave, and Edge?
Yes! Because those browsers are built on the Chromium open-source project, Supashot is 100% compatible. You can download and run it directly from the Chrome Web Store on Arc, Brave, Microsoft Edge, Opera, and Vivaldi.
What host permissions are required for the extension?
To guarantee capture triggers from the service worker behave correctly without falling out of permission bounds, standard host permission for http/https sites is utilized. This enables regional overlays and scrolling captures to be injected instantly on your active tabs without timing delays or gesture locks.
