Real-time error tracking assists the QA team in swiftly identifying and reporting bugs
One of the greatest advantages of Sentry is its support for Azure Web Services, which New Relic does not support. Sentry integrates with common developer communication platforms like Discord and WhatsApp, which allows developers to easily track notifications and findings in the applications. Real-time error tracking helps our Quality Assurance team easily identify the root causes of problems or bugs and promptly inform the developers about specific issues.
