What is Aviator?

Aviator's MergeQueue now has an LLM tell flaky failures from real ones and rerun them.

Aviator is a merge queue and stacked PR platform; MergeQueue batches and validates pull requests to keep trunk green. The October 1 beta uses an LLM to read a failed check's logs, separate flaky failures from real ones, rerun the flakes and keep the PR queued instead of resetting everything behind it. September brought dark mode and merge timing metrics exportable to Prometheus or Datadog, and August added support for GitHub's native stacked pull requests.

What is Uptrends?

Synthetic monitoring built for people who script their checks, not click them.

Uptrends is a synthetic and digital experience monitoring service, and its recent releases cluster around multi-step API monitoring: bearer token authentication per API call, JWT encode and decode functions for signing and reading tokens, and a 30-second check interval for new Enterprise accounts. Around that sit account and workflow improvements — duplicable custom integrations, maintenance-period filtering by schedule attributes, SSL certificate monitors gaining the same HTTP and TLS version options as HTTPS monitors, and automatic SSO redirect at login. The August entry is a support-matrix change rather than a feature: Windows Server 2019 is no longer offered for new private location installations.

Aviator's MergeQueue now has an LLM tell flaky failures from real ones and rerun them.

◆ Current state

Aviator is a merge queue and stacked PR platform; MergeQueue batches and validates pull requests to keep trunk green. The October 1 beta uses an LLM to read a failed check's logs, separate flaky failures from real ones, rerun the flakes and keep the PR queued instead of resetting everything behind it. September brought dark mode and merge timing metrics exportable to Prometheus or Datadog, and August added support for GitHub's native stacked pull requests.

◆ Where it's heading

After exposing stacked PRs to AI coding agents in April, Aviator is now applying an LLM inside the queue itself, attacking the main cost of merge queues: one flaky test stalling every PR behind it. The timing metrics export points the same way: the product is being tuned for teams measuring queue throughput, and AI is used to raise it.

◆ Prediction

Expect the flaky test beta to move toward general availability, likely with flake reporting surfaced in Inbox or the metrics export. The entries do not indicate timing.

Synthetic monitoring built for people who script their checks, not click them.

◆ Current state

Uptrends is a synthetic and digital experience monitoring service, and its recent releases cluster around multi-step API monitoring: bearer token authentication per API call, JWT encode and decode functions for signing and reading tokens, and a 30-second check interval for new Enterprise accounts. Around that sit account and workflow improvements — duplicable custom integrations, maintenance-period filtering by schedule attributes, SSL certificate monitors gaining the same HTTP and TLS version options as HTTPS monitors, and automatic SSO redirect at login. The August entry is a support-matrix change rather than a feature: Windows Server 2019 is no longer offered for new private location installations.

◆ Where it's heading

The product is being shaped around authenticated, scripted API checks rather than simple uptime pings, and the pieces arriving are the ones that make a monitor look like a real client — token signing, per-call authentication, sub-minute frequency. The second direction is outward: OpenTelemetry export lets monitoring results land in Elastic, New Relic, Splunk, Prometheus or ITRS alongside application and infrastructure telemetry, and the Terraform Hub can emit import blocks for individual resources. Both point at customers who already run an observability stack and want Uptrends inside it rather than beside it.

◆ Prediction

Expect the Enterprise tier to keep receiving the sharper capabilities first, since both the 30-second interval and OpenTelemetry export shipped that way, and expect further authentication methods for multi-step API monitors given the run from bearer tokens through JWT functions.
