Mergify
What Mergify is
Mergify automates pull request merging for teams that want changes to reach a green main branch through merge queues, CI insights, flaky-test tools, and merge protections. Its queue rebases each pull request onto the latest main and merges it only when CI passes against the combined state. Teams can batch pull requests into one CI run; if a batch fails, Mergify can bisect it to find the cause.
CI Insights reports unreliable jobs, retries them automatically, and provides data for investigating root causes. Merge Protections supports custom rules, scheduled merge windows, freeze periods, and exceptions for urgent fixes. Merge Queue works with any CI system that reports status checks to GitHub, while deeper CI Insights integrations are available for selected providers. Listed integrations include GitHub, GitHub Enterprise, GitHub Actions, Jenkins, Buildkite, Slack, Datadog, and Terraform, alongside test frameworks.
The Free / Open Source plan costs nothing for open-source projects or private teams of up to five users and includes all four products with email support. Max costs $21/user/mo, billed per seat per month, and includes up to 100 users, all four products, 30-day data retention, and a 14-day free trial. Enterprise pricing is custom, with unlimited users, custom data retention, optional on-premise deployment, and dedicated support. Mergify was founded in 2018 and is headquartered in Toulouse, France.
