Paste a trace string from the crash reporter to remap it to source code:
What is this?
We made this little tool to help debug panics and crashes in Bun.
Instead of bloating Bun's binary with hundreds of megabytes of debug symbols, we put the version, platform, and stack addresses into a VLQ-encoded URL.
On a panic or crash, we print the URL to this page, which this tool re-maps into a stacktrace. From there, we redirect to a GitHub issue prefilled with the stack trace.
This is similar in spirit to a JavaScript sourcemap.
Note: these URLs contain no source code or personally-identifiable information (PII). The stackframes point to Bun's open-source native code (not user code), and are safe to share publicly and with the Bun team.
