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.
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 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.
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 has moved well past AI code editor into multi-agent development infrastructure.

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.
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.
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.
