Merge Queue

Stop breaking main

Two PRs pass CI. Both merge. Main breaks. Sound familiar?

Mergify's merge queue tests every PR against the actual state of your main branch before it merges.
Broken builds never reach production.

Why PRs that pass CI still break main

When two PRs are developed in parallel, each passes CI against its own base. But when both merge, their combined changes can conflict, not just textually but semantically. Mergify's merge queue catches this by updating each PR to the latest main before running CI.

Up-to-date pull requests & test run

Every PR is rebased on the latest main and retested before it merges. No stale bases, no surprises.

Intelligent retesting

If a PR would break main, it gets caught before it merges. Not after.

Conflict resolution

When PRs conflict, Mergify picks the right one to merge and notifies the author of the other. No manual triage needed.

Early on, as the team, tests, and CI complexity grew, it was quite clear that we needed an automated tool to resolve bottlenecks. Our team loves the way Mergify solved our growing pains.

Stop paying for CI runs that don't matter

Running CI on every pull request regardless of merge readiness wastes compute and money.

Batch processing

Group PRs by scope and test them together in a single CI run. If a batch fails, bisect-on-failure finds the culprit automatically.

Two-step CI

Run fast checks on every push. Save the full test suite for PRs that are actually ready to merge. Less CI waste, faster feedback.

Mergify is a no-brainer. If you want to have your main branch always working then you have to introduce some merge queue functionality.

See exactly where it falls short and what Mergify adds: batching, priorities, two-step CI, monorepo scoping, and more.

Built for pipelines that take hours, not minutes

Firmware builds, OS validation, hardware-in-the-loop testing. When CI runs are expensive, every wasted minute compounds.

Long test cycles

Multi-hour pipelines make every failure expensive. Two-step CI runs lightweight checks first.

Flaky tests at scale

One intermittent failure can stall dozens of engineers. Auto-retry and quarantine keep the queue moving.

CI costs spiral

Big jobs plus reruns multiply your bill. Batching tests PRs together and bisects on failure to avoid waste.

Rigid queues

No two-step validation, no smart batching, no priority lanes. Mergify gives you all of these out of the box.

With dozens of engineers and long-running CI jobs, Mergify turned what used to be a daily bottleneck into a background process. Our teams focus on hardware, not merge logistics.
