DeepSpace is a full-stack SDK and hosting platform for real-time React and TypeScript apps. One npm package, deepspace, includes a real-time database, sign-in, presence, collaborative editing, file storage, and Stripe payments. One command, npx deepspace deploy, puts the frontend and backend live at <name>.app.space.

DeepSpace is designed for AI coding agents. New projects include an agent skill, and CLI commands can return JSON. Permission checks, identity verification, and payment flows are handled inside the SDK, so agents do not rewrite them for each project.

Liveblocks describes itself as "the realtime infrastructure to handle concurrent edits on shared data, so people and AI agents can collaborate without breaking your app." Its products are Sync, Comments, and Notifications.

Liveblocks works with Yjs and has integrations for the Tiptap, Lexical, and BlockNote editors, React Flow, Redux, and Zustand. Its client libraries are open source under Apache 2.0, and its server is open source under AGPL-3.0. As of October 2026, Liveblocks does not offer self-hosting for production.

The main difference is scope. Liveblocks is a collaboration layer that you add to an app with its own database, auth, and hosting. DeepSpace is the whole app platform, with collaboration built in.

Liveblocks has more prebuilt collaboration UI, and it fits into any stack. DeepSpace includes the parts of the app around collaboration, so there are fewer services to connect.

Both handle presence, live cursors, shared state, and collaborative text. Liveblocks has the deeper set of collaboration features. It offers prebuilt Comments and Notifications, React UI components, and integrations for several editors and React Flow.

In DeepSpace, the usePresence and usePresenceRoom hooks show who is online and broadcast cursors and typing state. Collaborative text runs on Yjs. A Tiptap editor and a shared canvas with undo and redo are available as add-on features. DeepSpace also includes public chat channels with reactions and read receipts.

Usually yes. Liveblocks stores shared state for each collaboration room. Your users, accounts, and other app data live in your own database and backend.

DeepSpace includes the app database. Each collection is a typed table, and the useQuery hook keeps components in sync over a WebSocket. Queries filter by exact match, sort, and limit. For full SQL, a DeepSpace app can attach a Cloudflare D1 database. Scheduled tasks, background jobs, and your own API routes run in the same Cloudflare Worker.

Liveblocks does not include user sign-in. You authenticate users in your own backend and give Liveblocks a token that identifies them. Liveblocks then applies access permissions for each room.

DeepSpace includes Google and GitHub sign-in, and the platform manages sessions. Permissions are role-based rules, such as viewer, member, and admin, declared next to each collection's schema and enforced on the server.

DeepSpace has payments built in. You declare subscription plans and one-time products in code, and they sync to Stripe when you deploy. Hooks and a pricing table component handle checkout. Server helpers check subscriptions and handle refunds and cancellations.

Liveblocks does not handle payments. With Liveblocks, billing is part of your own backend.

Both support coding agents. Liveblocks offers an MCP server and agent skills. Its product also treats AI agents as collaborators that edit shared data next to people.

A DeepSpace project includes an agent skill, and the CLI returns JSON for scripting. An agent can build and deploy the frontend, backend, sign-in, and payments together. You connect a Stripe account once before taking payments. With Liveblocks, the agent also has to set up the database, auth, and hosting.

Both have free plans. DeepSpace is free to start building and deploying, and paid plans add more deployed apps and usage.

As of October 2026, the Liveblocks free plan includes 3,000 collaboration minutes, 200 comments, and up to 10 simultaneous connections per room. Pro starts at $30 per month, and Team starts at $600 per month. Usage is metered, for example $0.002 per collaboration minute and $0.01 per comment. The database, auth, and hosting that run next to Liveblocks are billed separately.

Choose Liveblocks when you already have an app and want to add collaboration to it. It is also the better fit when you want prebuilt comments, notifications, or editor integrations, or when your frontend, backend, and auth are already decided.

Consider DeepSpace when you are building a new real-time app and want the database, sign-in, payments, and hosting on one platform with collaboration included.
