Code Mappings connect errors to the source code in a repository. And since errors can have paths that are different from the tree structure of the repository, Code Mappings determines the accurate path through a combination of a repository URL and a path transformation.
Sentry uses Code Mappings to serve issue context on the issue details page.
We’re making Session Replay generally available to all Sentry users. Remove the guesswork from troubleshooting by seeing video-like reproductions of what users experience leading up to and after an error or performance issue. Session Replay supports all web-based platforms.

Our developers easily identify and resolve performance bottlenecks – like querying the database while iterating over a collection rather than prefetching –, resulting in up to orders of magnitude fewer database queries, and shorter response times.
