What is FireHydrant?

On-call overrides now survive a schedule edit — and are the only way to change a shift.

FireHydrant shipped a real override layer for on-call schedules. Overrides now survive schedule edits made from either the web UI or the API, always win against an overlapping generated shift, can be stacked, and can be cancelled to restore the original system-generated shift. Reassignment, coverage requests, and shift deletion no longer mutate the generated schedule at all — each creates an override instead, which is what makes every change cleanly undoable. The constraint is historical: restoring a shift requires knowing what it originally looked like, and that data has only been tracked since 24 July 2026, so older rotations need a one-time regeneration first.

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.

On-call overrides now survive a schedule edit — and are the only way to change a shift.

◆ Current state

FireHydrant shipped a real override layer for on-call schedules. Overrides now survive schedule edits made from either the web UI or the API, always win against an overlapping generated shift, can be stacked, and can be cancelled to restore the original system-generated shift. Reassignment, coverage requests, and shift deletion no longer mutate the generated schedule at all — each creates an override instead, which is what makes every change cleanly undoable. The constraint is historical: restoring a shift requires knowing what it originally looked like, and that data has only been tracked since 24 July 2026, so older rotations need a one-time regeneration first.

◆ Where it's heading

The last year reads as one project — making an incumbent-grade on-call product safe enough to switch to. Customizable retrospective exports, authenticated status pages, consolidated analytics, an EU instance, MS Teams support, then the Signals Migrator that automates the move off PagerDuty and Opsgenie. Overrides fit the same pattern: a feature teams assume already exists, previously broken badly enough that admins learned not to touch a schedule once coverage was arranged. The work is closing table-stakes gaps ahead of a migration window, not opening new surfaces.

◆ Prediction

Expect the override model to be pushed out to the API and Terraform surfaces next, along with prompts to regenerate stale rotations before Opsgenie's April 2027 deletion date drives migration volume.

6.3

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.
