What is Aviator?

Aviator moves from merging code to judging it: Verify checks PRs against their stated intent.

Aviator is a merge queue and stacked PR platform. On October 20 it introduced Verify, which checks each pull request against what the change is supposed to do and the team's standing rules, so reviewers weigh evidence instead of reading the whole diff. That follows the October 1 beta in which an LLM separates flaky check failures from real ones and keeps PRs queued, plus September's queue timing metrics and August's support for GitHub's native stacked PRs.

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.

Aviator moves from merging code to judging it: Verify checks PRs against their stated intent.

◆ Current state

Aviator is a merge queue and stacked PR platform. On October 20 it introduced Verify, which checks each pull request against what the change is supposed to do and the team's standing rules, so reviewers weigh evidence instead of reading the whole diff. That follows the October 1 beta in which an LLM separates flaky check failures from real ones and keeps PRs queued, plus September's queue timing metrics and August's support for GitHub's native stacked PRs.

◆ Where it's heading

The arc runs from moving PRs (MergeQueue, stacks, Inbox) to deciding whether they are correct. April exposed stacks to AI coding agents, October 1 put an LLM inside the queue, and Verify now puts one in front of review, with criteria the agent writes after building. Aviator is positioning itself as the control layer for agent-written code between commit and merge.

◆ Prediction

Expect Verify results to feed the merge queue as a gate, since the same company owns both steps. The entries give no timing, and the docs fragments suggest the feature is still early.

Hatchet

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.
