Can I use it on several devices?

Yes. There is a single copy of your state on the server, so read state matches wherever you open it.

If I clear my browser data, do I lose my subscriptions?

No. Subscriptions and read state live on the server. Signing in again restores the same view.

Can I move to another service later?

Yes. OPML and a JSON export including read state, stars and tags are both available at any time.

What a cloud RSS reader is

The subscription list and read state live on the server, so every device you open it from sees the same thing.

Two approaches

RSS readers split mainly on where they keep state: inside the device as an app or browser extension, or on a server that you reach through a browser. The second is what "cloud" means here.

Keeping state on the device is self-contained, which is its appeal. The cost is that an article read on a laptop is still unread on a phone, and clearing browser data can take the subscription list with it.

Not synced — there is only one copy

With a cloud reader there is exactly one copy of the subscriptions, the read state and the stars, and it is on the server. No per-device copies are reconciled, so nothing drifts and you are never asked which version to keep.

Starting on a laptop and finishing on a phone works without ceremony. Signing in on a new device shows the same state again.

Fetching runs server-side too

A reader running on your device can only fetch while it is open. Leave it closed for a while and updates from that period are simply missed.

A cloud reader keeps fetching while your devices are shut. Scheduling — widening the interval for feeds that rarely update, not fetching ones that never do — also happens on the server.

What to check before committing

You are handing state to someone else, so what matters is whether you can take it back. Check that the subscription list exports as OPML, and ideally that read state and stars come out too.

Here, alongside OPML, a JSON export containing subscriptions, read state, stars and tags can be downloaded at any time.

What "free" covers

Fetching and storage cost money, so cloud readers commonly set limits or sell a paid tier. Since the boundary differs from service to service, the feed limit and the paid-only features are the two things worth checking first.

This service is funded by advertising and has no paid plan. Up to 1,000 feeds, with rules, full-text search and HTML-to-feed generation available to everyone on the same terms.
