Mergify is a merge queue and CI automation service for pull requests. Its merge queue batches pull requests and tests them together so that the main branch stays green. Related features include CI Insights for pipeline observability and automatic retries, and Test Engine for detecting flaky tests. It is offered as a hosted service with a web dashboard.
Mergify SAS is a French company with its head office in Toulouse, so it is established in the EU, and its privacy policy states that customer data is subject to the GDPR. The policy says subprocessors are bound by written data protection agreements and are listed on a trust portal, but their hosting locations are not stated on the pages reviewed. Whether the core product is open source was not confirmed. European organisations should check the subprocessor list and confirm the hosting region before connecting private repositories.
