getsentry/sentry ? reverse-engineered prompt

I'd like to build a full-stack, self-hostable application for error tracking and performance monitoring, something like Sentry. The primary goal is to give developers a central dashboard to see, debug, and resolve issues in their code as they happen in production.

It should support a wide range of languages and frameworks through small SDKs that developers can easily add to their projects, like JavaScript, Python, Java, and mobile apps. When an application crashes or has an error, the SDK should capture the full context—stack traces, user environment, etc.—and report it back to my platform.

The web UI should be clean, allowing users to view aggregated issues, see performance traces to identify bottlenecks, explore logs, and get alerts for new problems. A really important feature would be session replay, so we can watch what a user was doing right before an error occurred. Use Python for the backend and a modern JavaScript framework for the frontend dashboard.
