Liveblocks

Liveblocks is developer infrastructure for adding real time collaboration to an application, so that people and AI agents can work on the same shared data without overwriting each other. Its sync engine stores data across sessions and merges concurrent edits automatically using CRDTs, with presence, live cursors, offline support and multiplayer undo and redo included. The platform is aimed at engineering teams building collaborative products such as document editors, whiteboards, design tools and AI assistants. Beyond sync, it offers ready made building blocks for comments and notifications, delivered through React components and SDKs, plus a global edge network that runs realtime rooms close to users. Security features listed include SOC 2 Type 2 compliance, and the Enterprise tier adds multi region hosting, self hosting, SCIM and directory sync, and advanced permissions. Pricing is published on the vendor site. The Free plan is for personal development and testing, with 3,000 realtime collaboration minutes, 200 comments and 1 GB of data storage included each month. Pro costs $25 per month billed annually and includes $30 of monthly credits and removal of Liveblocks branding. Team costs $500 per month billed annually and includes $600 of monthly credits, extended version history and more simultaneous connections. Usage beyond the included amounts is metered, for example $0.002 per collaboration minute and $0.01 per comment. Enterprise pricing is custom.
