Case Study: fastlane achieves dramatically reduced build times and faster releases with CircleCI

Fastlane Chooses CircleCI to Power its Open Source Mobile Developer Tools

fastlane, an open‑source continuous delivery solution for iOS and Android (acquired by Google), faced high testing latency and slow builds that delayed feature and bug releases. Using prior CI tools like Jenkins, maintainers sometimes waited up to 20 minutes for machines to provision, which hindered rapid responses to issues and slowed delivery of value to customers.

fastlane switched to CircleCI for its faster Mac performance, reliable machine provisioning and responsive support, automating build, test and deploy pipelines for its Ruby/Swift stack. The move dramatically reduced build times and eliminated provisioning-related failures, enabling faster releases (running ~2,100 tests/day) and confident deployments to AWS and Heroku.
