Knock
Knock adds single-step test runs and retries for failed workflow runs.
A side-by-side editorial comparison of Aviator and WireMock — release velocity, themes, recent moves, and the top alternatives to consider.
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.
WireMock 4.0 is on its 41st beta, mostly fixes and dependency bumps after a big API rework.
WireMock is the standard Java tool for mocking HTTP APIs, and its 4.0 line is still in beta. The latest betas are dominated by Dependabot bumps and targeted fixes such as honoring the HTTPS trust-store type and making resetAll() clear message stubs. Beta.40 carried one breaking change: journal stores now enforce maxEntries themselves.

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.
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.

The structural work landed in June. Beta.35 introduced a unified Entity body abstraction across stubs, webhooks and messages, and added breaking-change reporting on the published API. Since then the releases have been stabilization, with message channels getting most of the attention. The project is converging, not expanding.
Expect more betas that fix message channels and the journal, with the breaking-change reports gating a 4.0 release candidate. The entries give no date for GA.
