Bitrise is a continuous integration and delivery platform built specifically for mobile app development, automating how iOS and Android apps are built, tested, code-signed, and distributed. Teams define pipelines from a large library of prebuilt steps or with configuration files, and Bitrise runs them on hosted macOS and Linux machines so there is no need to maintain a Mac build farm, with features for managing signing certificates and provisioning profiles, running unit and UI tests including on real devices, and deploying builds to testers, the App Store, and Google Play. It supports native, React Native, Flutter, and other frameworks, integrates with the common Git hosts and issue trackers, and provides build analytics and insights to spot flaky tests and slow steps. Bitrise is used by mobile teams from startups to large enterprises, and it has added capabilities around release management and, more recently, tooling that connects mobile CI with broader developer platforms. The company is independent and venture-backed, and it opened a European data center for customers with data-residency requirements. Bitrise offers a free tier for small and open-source projects, with paid plans priced by build concurrency, machine type, and usage, plus enterprise agreements.
