# BuzzKit vs OneSignal. The same job, nothing to assemble.

OneSignal is a hosted messaging service across push, email, SMS and in-app. BuzzKit is the open source layer that does the push part completely: sending, segments, scheduling, preferences, workflows and a ledger, from one API.

- You automate from events your backend and app already emit.

- You want a vendor with a long enterprise track record today.
- You need SDKs for every platform today, not iOS first.

## Questions

### Can I move from OneSignal to BuzzKit?

Yes. Device tokens belong to your app, so register them with BuzzKit through the iOS SDK or the subscriptions API, identify subscribers by your own ids, and recreate segments as expressions.

### Does BuzzKit support Android?

Not yet. BuzzKit starts with a complete iOS experience. Android sits on the same core and follows.

### Is the hosted version free?

The hosted version is free while BuzzKit is in beta, and self-hosting stays free. Existing workspaces will be told before any billing starts.
