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 SavvyCal?
SavvyCal keeps polishing scheduling ergonomics on a slow, steady cadence.
SavvyCal is a scheduling tool competing on booking-experience quality. Its changelog moves at a measured pace — roughly one release a month — and the recent run is a series of contained refinements: duplicating workflows, locking links against last-minute changes, per-event buffer control, multi-language booking pages, and improvements to booking on behalf of others.

Hatchet
6.3INFRA · APIS
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.
SavvyCal
2.5INFRA · APIS
SavvyCal keeps polishing scheduling ergonomics on a slow, steady cadence.
◆ Current state
SavvyCal is a scheduling tool competing on booking-experience quality. Its changelog moves at a measured pace — roughly one release a month — and the recent run is a series of contained refinements: duplicating workflows, locking links against last-minute changes, per-event buffer control, multi-language booking pages, and improvements to booking on behalf of others.
◆ Where it's heading
The through-line is control and convenience for the host and for assistants who schedule for others: workflow reuse, guardrails on rescheduling, richer contact records, and localized booking pages. Nothing here shifts the product's category; it is deliberate incrementalism aimed at making the existing scheduling surface more flexible and reliable.
◆ Prediction
Expect more of the same — small, self-contained booking and workflow refinements on a monthly rhythm — absent any signal of a larger platform or AI move in these entries.
