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 pushes past the editor into an agent platform — automations, cloud agents, and its own models.
Cursor is expanding well beyond the IDE. In a dense stretch it shipped an automation platform (/automate) with GitHub and Slack triggers and computer use, cloud agents that set up dev environments and iterate autonomously, SDK extensibility with custom tools and nested subagents, and faster, cheaper Bugbot reviews powered by its in-house Composer 2.5 model. Design Mode adds point-and-voice UI editing in both the browser and canvases.

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
6.3INFRA · APIS
Cursor pushes past the editor into an agent platform — automations, cloud agents, and its own models.
◆ Current state
Cursor is expanding well beyond the IDE. In a dense stretch it shipped an automation platform (/automate) with GitHub and Slack triggers and computer use, cloud agents that set up dev environments and iterate autonomously, SDK extensibility with custom tools and nested subagents, and faster, cheaper Bugbot reviews powered by its in-house Composer 2.5 model. Design Mode adds point-and-voice UI editing in both the browser and canvases.
◆ Where it's heading
The direction is clear: Cursor is becoming an agent orchestration platform, not just an editor. External triggers and computer use turn agents into always-on automation, cloud environments and long-horizon iteration move work off the developer's machine, and the SDK opens the runtime to custom integrations. Owning the model layer with Composer 2.5 lets Cursor tune cost and speed on core features like code review.
◆ Prediction
Expect deeper automation triggers and tighter computer-use integration, more autonomous cloud-agent workflows, and continued Composer model rollouts powering more of the product beyond Bugbot.
