Buildstash vs Firebase App Distribution comparison

Firebase App Distribution helps developers share pre-release Android and iOS builds with groups of managed trusted testers for feedback and stability insights. It has good integration support including for Gradle, fastlane, and a number of CI/CD tools.
Buildstash is a platform for software binary and release management, supporting not just mobile apps, but also desktop, games, XR, and embedded. It offers extensive collaboration features, QA workflows, and more extensive options for distribution across not just distribution groups, but quick share links, notification automations, and custom-branded download portals.
