| Question | Answer | Source |
|---|---|---|
| Is it actively maintained? | active v3.24.5 on 2026-10-23; rebranded Storage as 'Liveblocks Sync'; server open-sourced (AGPL) in Feb 2026 for local dev/testing | 2026-10-25 |
| How is the main thing licensed? | stands apart copyleft or source-available with restrictions v4: from the map's own 'license' question. Clients Apache-2.0, server components AGPL-3.0; production service proprietary | source 2026-10-25 |
| How is it mainly sustained? | company with a paid product, tier, or ads v4: from the map's own 'business' question. | source 2026-10-25 |
| Can it run entirely on your own device or infrastructure, without the maker's servers? | stands apart partly (some features need the maker's servers) v4: from the map's own 'self_host' question. @liveblocks/server (AGPL) and dev server exist, aimed at local dev/CI; production self-hosting not documented | source 2026-10-25 |
| Do you need an account to use it? | stands apart account required Hosted service; quickstart needs a public API key; free plan still requires sign-up. | source 2026-10-26 |
| Who is it for? | developers v4: from the map's own 'audience' question. | source 2026-10-25 |
| Which shared standard or format does it mainly build on? | none of these (its own format or interface) Own Storage model; Yjs is an option, not the default. | source 2026-10-26 |
| Does an app built on it keep working fully offline, for both reads and writes? | stands apart partly (reads only, or only data that was cached) Optimistic local edits queue while offline and merge on reconnect, but no durable client database by default | source 2026-10-25 |
| What does it need to sync between devices? (first that applies) | stands apart the maker's hosted cloud service | source 2026-10-25 |
| If the company behind it disappeared, would apps keep working? | stands apart no Data lives in Liveblocks' hosted storage | source 2026-10-25 |
| Is end-to-end encryption built in? | no | source 2026-10-25 |
| What shape of data does your app read and write? | JSON-like documents Rooms holding LiveObject/LiveList/LiveText or Yjs docs | source 2026-10-25 |
| How are concurrent edits resolved? (first that applies) | a server decides (it rebases or rejects client writes) Figma-style 'CRDT-like' model with Liveblocks as source of truth; Yjs option is a true CRDT | source 2026-10-25 |
| Where does synced data live on the server side? | in its own sync server or relay Liveblocks hosted storage; REST API/webhooks to export | source 2026-10-25 |
| Where does it keep data on the client by default, on its main platform? | stands apart in memory or its own files | source 2026-10-25 |
| How much data syncs to each client? | whichever documents or stores the app opens Per room | source 2026-10-25 |
