Sentry

Sentry provides comprehensive application performance monitoring and error tracking, designed for developers to resolve issues quickly. It helps you pinpoint the exact line of code causing an error, understand the impact on users, and automate your workflow with integrations like Slack, Jira, and GitHub. The platform goes beyond simple error reporting, offering a suite of powerful tools:

• Full-Stack Tracing: Visualize the complete path of data through your distributed system to find and fix performance bottlenecks.
• Session Replay: See what your users experience with a visual replay of their session, including console logs and network requests, all while protecting user privacy.
• Code Coverage: Analyze test coverage directly within your pull requests to catch potential issues before they reach production.

Trusted by over 4 million developers, it provides the context needed to not just observe problems, but to actively solve them.
