What is Hatchet?

Hatchet takes durable tasks serverless, with handlers for Cloudflare Workers, Vercel and Node.

Hatchet's new @hatchet-dev/serverless 0.1.0 runs tasks on Cloudflare Workers, Vercel and Node. An in-engine operator delivers them by signed POST or by an invocation websocket that also carries durable sleeps, waits and child runs. Around it, the engine shipped three patches in a day: DAG replays no longer take an advisory lock, worker shutdown now waits for durable tasks, and status queries use partition pruning. The API now declares 429 with Retry-After on every authenticated call.

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.

Hatchet takes durable tasks serverless, with handlers for Cloudflare Workers, Vercel and Node.

◆ Current state

Hatchet's new @hatchet-dev/serverless 0.1.0 runs tasks on Cloudflare Workers, Vercel and Node. An in-engine operator delivers them by signed POST or by an invocation websocket that also carries durable sleeps, waits and child runs. Around it, the engine shipped three patches in a day: DAG replays no longer take an advisory lock, worker shutdown now waits for durable tasks, and status queries use partition pruning. The API now declares 429 with Retry-After on every authenticated call.

◆ Where it's heading

Until now, running Hatchet meant running long-lived workers. The serverless package removes that requirement, so durable execution can run where JavaScript teams already deploy. The engine work points the same way: rate limits declared in the spec, safer worker acks, cheaper status queries. Patch cadence is still very high, often several engine tags a day, and much of it fixes durable-task edge cases.

◆ Prediction

Expect quick 0.1.x serverless releases as early users hit edge cases on each platform, and possibly matching Python handlers. More engine patches on durable-task shutdown and replay are likely.

4.4

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.
