Liveblocks
Hosted collab rooms; Free $0 pauses at the cap
Comms / Realtime · Freemium · 4.7k
What's Good
Free is $0, no credit card. Caps: 3,000 collab minutes, 200 comments, 1 GB realtime storage, 512 MB files, 10 connections/room, 3 dashboard seats. Watermark required. Presence, comments, Yjs, storage. Pair with /skills/liveblocks-best-practices for the cookbook — this page is the product Catch, not the skill.
The Catch
Free pauses at the cap until the next cycle — not PAYG. Pro is $30/mo (credits + drop branding). Self-host is an Enterprise add-on, not the OSS path. Distinct from Socket.IO (you run the server) and Centrifugo (Go binary you operate).
Verdict
Hosted collab with a real $0 Free. Caps pause the feature; Pro is $30; self-host is sales.
