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 CircleCI?

CircleCI's SSH reruns now open from the browser, through one trusted address.

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

Aviator vs CircleCI: editorial side-by-side

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.

CircleCI

6.3

CircleCI's SSH reruns now open from the browser, through one trusted address.

◆ Current state

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

◆ Where it's heading

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.

◆ Prediction

Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.
