Overview

Bugsnag is an error monitoring platform that captures JavaScript exceptions and application crashes. Development teams use it to detect, diagnose, and prioritize production errors in real time.

What This Script Does

The Bugsnag notifier script captures unhandled JavaScript exceptions and sends error reports to Bugsnag's servers. Each report includes the error message, stack trace, browser environment (user agent, OS, browser version), and user breadcrumbs (recent actions that led to the error). Bugsnag does not set advertising cookies, does not build behavioral profiles, and does not collect data for marketing purposes. It may optionally include a user identifier if configured by the development team for error correlation.

Consent & Compliance

Consent category: Functional

Bugsnag serves a technical monitoring function essential for application quality. Under GDPR, error monitoring for service reliability can qualify as a legitimate interest. The data collected (error details, browser environment) is used solely for debugging. Under ePrivacy, if Bugsnag does not set tracking cookies, no cookie consent is required. If user identifiers are attached to error reports, this should be disclosed in the privacy policy.

Should You Block This Without Consent?

No. Bugsnag is an error monitoring tool that collects only technical error data. It does not track users for marketing or analytics purposes. It can be loaded as a functional script without consent.

Frequently Asked Questions

Do I need consent to run Bugsnag on my website?

Conditional. Bugsnag is a functional error monitoring tool — it captures crashes and exceptions to help developers fix bugs. It does not build advertising profiles or set tracking cookies. Under GDPR, error monitoring tools that collect minimal technical data may not require explicit consent, but you must disclose them in your privacy policy.

What data does Bugsnag collect from site visitors?

Bugsnag captures unhandled JavaScript exceptions and sends error reports including stack traces, browser type and version, OS, and user breadcrumbs (recent actions before the error). It does not set advertising cookies or track behavioral data for targeting purposes. Reports are sent to Bugsnag's dashboard for developer review.

How does ConsentStack manage Bugsnag on my site?

ConsentStack detects the Bugsnag notifier script and classifies it as functional. Functional scripts may load without marketing consent under many consent frameworks. ConsentStack allows Bugsnag to run by default in functional-allowed configurations, but it can be gated behind consent if your policy requires it.
