Main stays green.
Your team stays fast.
Two PRs pass CI. Both merge. Main breaks.
Mergify tests every PR against the real state of main before it merges. The bigger your team, the more it matters.
PRs pass CI individually.
Together, they break main.
When PRs are developed in parallel, each passes CI against its own base. But when both merge, their combined changes conflict in ways that no diff can show. The more engineers you have, the more often this happens.
Every PR tested against the real state of main
Mergify updates each PR to the latest main and retests it before merging. If the combined state would break, Mergify catches it and notifies the author. No broken main, no manual triage.
Automatic rebase and retest
Every PR is rebased on the latest main and retested before it merges. No stale bases, no surprises.
Automatic conflict resolution
When PRs conflict, Mergify picks the right one to merge and notifies the author of the other. No manual triage needed.
Mergify is a no-brainer. If you want to have your main branch always working then you have to introduce some merge queue functionality.

Your CI bill keeps growing but
your merge rate doesn't
Running full CI on every pull request regardless of merge readiness wastes compute and money. Most of those runs are thrown away.
Batch processing
Group PRs 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.
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.

Your queue is the bottleneck
With 30-minute CI and a serial queue, you top out at ~48 PRs per day. In a monorepo, it's worse: unrelated changes block each other for no reason.
Your team writes code faster than the queue can merge it.
Parallel queues and scopes remove the bottleneck
Mergify tests multiple PRs concurrently against predicted future states of main. Scopes let you tag PRs by area (frontend, backend, infra, docs) so unrelated changes merge independently. A CSS fix no longer waits behind an API migration.
Speculative checks
If PR #3 depends on #1 and #2 succeeding, Mergify builds that speculative state and tests against it. No waiting in line.
Scope-based merge lanes
Define scopes based on file paths or labels. Each scope gets its own queue. PRs in different scopes merge independently without blocking each other.
Higher merge throughput
Teams go from merging 10 PRs a day to 50+ without adding CI capacity. The queue stops being the thing everyone complains about.
Already using GitHub's merge queue?
See exactly where it falls short and what Mergify adds: batching, priorities, two-step CI, monorepo scoping, and more.
Most teams can't explain why
their queue is slow
Mergify gives you full visibility into throughput, wait times, failure rates, and batch outcomes. You see what's slowing you down and fix it with data.

Built for pipelines that take hours, not minutes
Firmware builds, OS validation, hardware-in-the-loop testing, multi-stage deployments. 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. Batch processing groups PRs together and bisects on failure to avoid waste.
Hotfixes stuck in line
A critical fix shouldn't wait behind 20 feature PRs. Priority queues let urgent changes jump ahead and merge first.
Real teams, real results
Engineering teams we helped merge faster, safer, and cheaper
Move faster. Break less.
Purpose-built for teams who take delivery speed and reliability seriously.
