Case Study: Carousell scales automation 13x and cuts regression testing from a day to an hour with BrowserStack

Asia’s Largest Classified Marketplace Uses BrowserStack to Scale Automation

Carousell, Asia’s largest classified marketplace, was releasing features weekly but release days were stressful: a small QA team, a difficult-to-maintain in-house device lab and a restrictive device farm meant slow, flaky test feedback. To get stable, scalable automation and continuous testing in their CI pipeline, Carousell evaluated and chose BrowserStack (using App Automate and BrowserStack Real Device Cloud) to replace their infrastructure bottlenecks.

By integrating BrowserStack’s App Automate/Real Device Cloud, Carousell scaled automation runs 13x, cut regression testing from a day to an hour, and reduced average manual regression effort from ~35 hours to ~5 hours (about a 7x improvement). BrowserStack’s reliable, on-demand infrastructure eliminated false positives, freed testers to build higher‑coverage automation, and made stress‑free, potentially daily releases possible.
