Bugsnag is an application stability monitoring platform specialising in error detection, classification, and prioritisation — used by development teams to monitor application health and catch bugs before they impact a critical number of users. SmartBear acquired Bugsnag, positioning it within the broader SmartBear quality tooling portfolio alongside SwaggerHub and TestComplete. AI Error Grouping uses ML to cluster related error occurrences intelligently — reducing the alert noise of thousands of duplicate errors to manageable prioritised issues without requiring manual grouping rule configuration. Stability Scores provide app-wide health metrics — measuring the percentage of user sessions that are error-free, providing a single metric for application stability management rather than monitoring error counts alone. Severity Scoring uses ML to assess the business impact of errors — considering error frequency, affected user count, user segment (premium vs. free), and session disruption to prioritise which errors to fix first rather than treating all errors equally. Release Health Tracking monitors stability changes across new releases — identifying whether a new deployment improved or degraded application stability. Breadcrumbs capture the user events and application state leading to each error — providing the context that makes root cause identification faster than stack traces alone. With customers including Airbnb, Shopify, and Yelp across accommodation, e-commerce, and local discovery, Bugsnag validates across major consumer applications for mobile and web stability.
Bugsnag AI runs as ml platform software built around data and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, ios (sdk), and android (sdk), with API access for teams that want to embed it into their own products.
