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 Nextflow?

Nextflow just made AI agents a task type, alongside processes and containers.

Nextflow ships on two tracks — dated edge releases carrying new work and 25.10.x/26.04.x stable lines taking backports — and the split is visible in every window: the edge builds run to dozens of commits while the stable patches are often plugin bumps alone. The current edge, 26.08.0-edge, introduces an agent primitive that makes AI agents first-class tasks, on top of steady work hardening the v2 config parser and type system. Cloud-executor plumbing, particularly for Seqera's own scheduler, is the other constant.

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.

Nextflow

6.3

Nextflow just made AI agents a task type, alongside processes and containers.

◆ Current state

Nextflow ships on two tracks — dated edge releases carrying new work and 25.10.x/26.04.x stable lines taking backports — and the split is visible in every window: the edge builds run to dozens of commits while the stable patches are often plugin bumps alone. The current edge, 26.08.0-edge, introduces an agent primitive that makes AI agents first-class tasks, on top of steady work hardening the v2 config parser and type system. Cloud-executor plumbing, particularly for Seqera's own scheduler, is the other constant.

◆ Where it's heading

Two arcs run in parallel. One is language maturity: the v2 parser, record types, typed outputs and the formatter have absorbed fix after fix across every release here, which is what a language does before it declares a syntax stable. The other is consolidation around Seqera — nf-tower folded into nf-seqera at 1.0.0, scheduler run identifiers propagate to Platform, and per-user CPU caps and secret references now cross that boundary. The agent primitive is the newest and least settled direction, arriving in edge rather than a stable line.

◆ Prediction

The agent primitive lands in an edge build, so the near-term question is whether it survives into a stable line unchanged or is reshaped first; the 26.04.x and 25.10.x branches show no sign of it yet. Expect the next edge releases to iterate on its interface while the stable branches continue taking parser and executor backports.
