  • Our PR generator cranks out 200 PRs/hour and submits them to Trunk Merge Queue to be tested and merged into protected branch
  • Parallel mode: Merge Queue analyzes each PR's Bazel impacted targets to create dynamic parallel graph—PRs with non-overlapping target sets test simultaneously
  • CI runtime: 5 minutes per PR
  • 10% of PRs have flaky tests (pass 30% of the time)
  • 1% have logical merge conflicts (always fail)
  • Merge queue batches: 4 PRs at a time

Guess how many PRs Trunk Merge Queue can process in 4 hours

Make Your Guess

Merge Queue

The only merge queue that leverages your Bazel build graph to create parallel merge lanes - guaranteeing main stability while maximizing throughput.

Parallel Queues

Run unrelated changes through CI at the same time. Thanks to built-in support for tools like Nx and Bazel, Trunk Merge Queue groups and tests related PRs in a single queue while unrelated PRs are run in parallel.

Flaky Tests

Cache-aware flaky test detection built for Bazel's complexity.

Direct BEP ingestion means we understand your remote execution environment and can distinguish test flakiness from cache issues.
