Does Floccus Support Mobile Devices and Tab Syncing?

Yes, Floccus supports both mobile devices and tab syncing, but with an important limitation on mobile. Floccus offers apps for iOS and Android that sync your bookmarks and tabs, and it also provides tab-syncing guides. However, on mobile the app currently syncs only to a folder inside the Floccus mobile app — not to mobile browsers — and Floccus support across available mobile browsers is described as sparse. Safari is not supported at all due to technical limitations.

Mobile support: what you actually get

Floccus provides apps for browsers, iOS, and Android. The mobile app is the part that matters for phones and tablets, and its scope is narrower than the desktop browser extensions.

The practical consequence: if your goal is to have the same bookmarks appear inside Chrome or Firefox on your phone, the mobile app does not do that today. What it does give you is a synced copy of your bookmarks and tabs inside the Floccus app itself, which you can consult on the go.

Why the mobile limitation exists

Floccus works by syncing bookmark data through a storage backend you choose. On desktop, browser extensions can read and write the browser's own bookmark store. On mobile, the app keeps its synced data in its own folder rather than writing into each mobile browser's bookmark system — which is why the sync stops at the app boundary. The site states this directly and also notes that Safari is excluded for technical reasons.

Tab syncing

Tab syncing is a supported feature, not an afterthought. The site points readers to dedicated guides for it, and the feature matrix lists tab-related capabilities alongside bookmark sync. If tab syncing is your main reason for looking at Floccus, check the guides before committing, since what syncs depends on the storage service you pick (see below).

Storage backends and what they affect

Floccus does not store your data itself. It syncs through a service you choose, which is also how it keeps privacy in your hands: no ads, no data collection, and free and open source software. The feature matrix shows which services support which capabilities, including end-to-end encryption (E2EE) and order preservation.

Two takeaways from this table:

• If E2EE matters to you, Nextcloud is the only listed service with a clear ✅. WebDAV, Google Drive, and Dropbox show a parenthesized (✅), which suggests conditional support rather than a firm yes — treat those as "check the details" rather than guaranteed.
• If you want self-hosting, Nextcloud, Linkwarden, Karakeep, WebDAV, and Git over HTTPS all fit; Google Drive and Dropbox are the low-effort hosted options. OneDrive is listed as planned, so don't count on it yet.

Choosing based on your situation

• You want bookmarks inside your phone's browser. Floccus does not currently deliver this. Look elsewhere, or accept the app-folder workflow.
• You want a private, self-hosted sync across desktop browsers, plus a mobile reference copy. Floccus fits well — pick Nextcloud if E2EE is a priority, or WebDAV/Git if you already run that infrastructure.
• You mainly want tab syncing. Supported, with guides available; confirm your chosen backend's tab behavior in the feature matrix first.
• You use Safari. Not supported. This applies on desktop and mobile alike.

Getting started

The site offers a download link, a "Get started" entry point, and an intro video. The project is volunteer-run — led by creator Marcel Klehr — and accepts issues, pull requests, and translation help if you want to contribute.
