BugSnag vs EAS Observe

BugSnag monitors mobile and web applications to help development teams find errors, resolve them, and deploy stable releases. Its error inbox groups issues by root cause and sorts them by user impact. Captured diagnostics can include stack traces, threads, breadcrumbs, device details, and user information. Stability Center provides a 30-day stability score and trend analysis for each application, while performance monitoring captures app starts, screen loads, and Web Vitals. BugSnag provides error-reporting libraries for more than 50 platforms, including Android, iOS, JavaScript, macOS, Flutter, and React Native. Integrations named include Slack, Microsoft Teams, PagerDuty, OpsGenie, GitHub, GitLab, Jira, Splunk, and Amazon SQS. The Free plan lists one user, 7,500 events and 1 million spans per month, and seven days of data retention; a 14-day free trial is also listed. Select and Preferred list 60 days of retention. Enterprise offers custom retention and can be hosted on customer infrastructure or a cloud instance. Enterprise security features include two-factor authentication, SAML single sign-on, sensitive data management, and user audit logs.

EAS Observe is a production performance monitoring service for apps running on real devices and conditions. It records cold and warm launch times, time to first render, time to interactive, bundle load time, and EAS Update download time. Measurements can be compared across app versions and over-the-air updates to help identify regressions. Expo Router and React Navigation integrations add render and interactive timings for individual routes. Apps can send user-defined events with Observe.logEvent and analyze them with performance data. Results appear in the EAS dashboard or can be queried from the terminal with EAS CLI commands. EAS Observe supports Android, iOS, and tvOS, but requires Expo SDK 55 or later and an app linked to an EAS project. It is unavailable in Expo Go and needs a development or production build. JavaScript error and native crash reporting are preview features. Plans include Free at $0/month, Starter at $19/month plus additional usage, and Production at $199/month plus additional usage; Enterprise pricing is custom. Retention is 90 days.
