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 Railway?
Railway's weekly cadence is building a PaaS for AI agents: MCP, Cloud Agents, no-barrier entry.
Railway ships at roughly weekly cadence across two clear vectors: agentic infrastructure and frictionless entry. Cloud Agents—persistent, resumable background agents—are now live across dashboard, CLI, and mobile. Alongside that, Railway has progressively eliminated signup friction: no-account deployment for sites and databases, free Sandboxes, and now free VMs, all on the same production-grade stack.

Liveblocks

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.
Railway
6.3INFRA · APIS
Railway's weekly cadence is building a PaaS for AI agents: MCP, Cloud Agents, no-barrier entry.
◆ Current state
Railway ships at roughly weekly cadence across two clear vectors: agentic infrastructure and frictionless entry. Cloud Agents—persistent, resumable background agents—are now live across dashboard, CLI, and mobile. Alongside that, Railway has progressively eliminated signup friction: no-account deployment for sites and databases, free Sandboxes, and now free VMs, all on the same production-grade stack.
◆ Where it's heading
Railway is converging its entry-tier and production-tier moves on a single architecture: Cloud Agents as the deployment primitive, MCP as the agent-accessible interface, and a growing roster of AI coding tools (Claude, ChatGPT, Grok, OpenCode) wired directly into that stack. The bet is that developers building agentic applications will want infrastructure that agents can deploy to and operate autonomously. Database management maturity (MySQL/Redis/Postgres HA, PITR, one-click major version upgrades) provides the backend layer that agentic workloads depend on.
◆ Prediction
The next likely move expands Cloud Agents further—persistent memory, inter-agent communication, or dedicated agent compute pricing. Each new AI coding tool integration (OpenCode is the latest) follows the same pattern; expect more.
