Bugfender offers in-app logging and bug tracking. Its SDK sends device logs, errors, and crash reports back to the developer, allowing real-time monitoring of app behavior and debugging even when no crash has occurred. It alerts developers to issues with detailed context (stack traces, logs, device info) so they can be fixed quickly. The company claims over 35,000 apps use Bugfender. It also highlights security compliance (ISO 27001, GDPR) for its service.
