As of 2026, GatherOS is a free public beta you can download for Mac. The team has not announced paid tiers or prices yet, so expect that to change as it leaves beta.

Does GatherOS work on Windows, the web, or mobile?

No. GatherOS is a Mac-only desktop app with a companion Chrome extension. There is no Windows build, web app, or mobile app, and your library lives on a single machine. Stashr runs in any browser on any device.

Which platforms can GatherOS capture from?

It auto-syncs your X bookmarks and Instagram saves, and its Chrome extension can clip images and full pages from anywhere on the web. Stashr auto-captures across X, Reddit, Instagram, and TikTok.

Does GatherOS keep permanent copies?

Yes. It stores saved tweets, images, and video as real files locally on your Mac, so they survive even if the original is deleted. The catch is that everything is local and Mac-only, with no cloud backup or cross-device access.

Stashr vs GatherOS

GatherOS is the one rival that matches Stashr's save-and-it-just-appears mechanic, pulling your X bookmarks and Instagram saves into a local library the moment you tap save. It is a lovely, designer-first Mac app with a Figma-like canvas, and it keeps real media files, video included, on your machine. The trade-offs are reach and access: it is Mac-only with no web or mobile, covers two social platforms plus a web clipper, and your library lives on one computer with no cloud sync.

Common questions

The verdict

If you are a designer who lives on a Mac and wants an open canvas to arrange visual inspiration, GatherOS is the real deal, and it is the only tool we have found that matches our capture-on-save mechanic for X and Instagram. It also stores real local files, so it archives video where Stashr keeps only a poster frame and the source link. Where Stashr pulls ahead is reach and access: we auto-capture across X, Reddit, Instagram, and TikTok, run in any browser on any device with your library in the cloud, and add search that finds saves by meaning rather than by color or visual similarity. Pick GatherOS for a single-Mac moodboarding workflow, and pick Stashr if you want one searchable library of everything you save, available everywhere.
