**Company:** Etsy

Etsy has two sets of mobile apps: buyers shop on one, and sellers run their businesses on the other.

In 2025, Etsy replaced the crash reporter behind their buyer app with Sentry. The migration was led by Jay Henry, a Senior Engineering Manager on the platform engineering side whose three teams cover CI, build, test, release, observability, and SRE for mobile apps. Etsy ran Sentry alongside the previous crash reporter through the 2025 holiday season before shutting the old one off.

Etsy confirmed that Sentry matched their existing solution in speed and accuracy, but with much-needed improvements in actionability and visibility.
