What is Liveblocks?

Liveblocks is rebuilding multiplayer collaboration around AI agents as first-class users.

Liveblocks shipped a six-week run of directional change: a brand-new React Flow SDK for collaborative node-graph editing, a Chat SDK adapter, a Feeds API explicitly framed for "Agent Workflows," a Python SDK for backend use, and v3.18 with breaking changes plus a mutateFlow() API that lets servers mutate diagrams from Node.js. The accompanying blog stream — "AI agents are becoming native users of software," feeds and APIs for agent workflows, n8n nodes — leaves no doubt about where the team is pointing. Underneath, the v1→v2 storage engine migration is in the long tail.

What is Cursor?

Cursor launches Projects: a coordinator agent that runs thousands of subagents in the cloud indefinitely.

Cursor has moved well past AI code editor into multi-agent development infrastructure. It now coordinates parallel subagents on cloud machines, hosts code natively via Origin Repos, and maintains persistent project context that grows across sessions. The Projects launch adds a coordinator layer that can delegate tasks to thousands of subagents, run without a local machine, and react to external triggers like Slack or GitHub PRs.

Liveblocks is rebuilding multiplayer collaboration around AI agents as first-class users.

◆ Current state

Liveblocks shipped a six-week run of directional change: a brand-new React Flow SDK for collaborative node-graph editing, a Chat SDK adapter, a Feeds API explicitly framed for "Agent Workflows," a Python SDK for backend use, and v3.18 with breaking changes plus a mutateFlow() API that lets servers mutate diagrams from Node.js. The accompanying blog stream — "AI agents are becoming native users of software," feeds and APIs for agent workflows, n8n nodes — leaves no doubt about where the team is pointing. Underneath, the v1→v2 storage engine migration is in the long tail.

◆ Where it's heading

Liveblocks is no longer just "realtime presence and comments for documents." It is positioning itself as the substrate where humans and AI agents share state — diagrams, chat threads, feeds — with the same primitives. The room.history.disable() API for hiding agent-generated writes from the undo stack is the small detail that gives the strategy away: the team is designing for a world where most edits in a room come from agents, and humans need to be shielded from that noise.

◆ Prediction

The next two minors should bring more agent-shaped APIs (auth scoping for agents, read-only agent participants, server-driven LiveObjects mutations from non-Node runtimes) and broader framework adapters beyond React Flow and Handsontable. Expect Liveblocks to pitch the Chat SDK adapter as a path off OpenAI's hosted threads when teams want agent conversation state stored on their own infra.

Cursor launches Projects: a coordinator agent that runs thousands of subagents in the cloud indefinitely.

◆ Current state

Cursor has moved well past AI code editor into multi-agent development infrastructure. It now coordinates parallel subagents on cloud machines, hosts code natively via Origin Repos, and maintains persistent project context that grows across sessions. The Projects launch adds a coordinator layer that can delegate tasks to thousands of subagents, run without a local machine, and react to external triggers like Slack or GitHub PRs.

◆ Where it's heading

Every release since mid-2026 has added a new layer of the autonomous-software-pipeline stack: code hosting (Origin Repos), always-on event-driven agents (Subscriptions), parallel subagent execution (team pools, per-VM isolation), and now a coordinator agent that owns long-running Projects end-to-end. The pattern is consistent — each release removes a human touchpoint that previously required manual intervention.

◆ Prediction

The next move is likely billing and governance for agent-compute at scale. Projects running thousands of parallel subagents implies compute costs that don't fit per-seat pricing; enterprise contracts around agent-hours or compute credits are the natural next step, especially with the self-hosted pool infrastructure already in place.
