Raygun Crash Diagnostics

| Limitation | Diagnostic Impact | Mitigation | |------------|------------------|-------------| | | Unreadable stack traces | Upload source maps to Raygun | | Cross-origin errors | Script error. (no details) | Add crossorigin="anonymous" + CORS headers | | Native crashes (C/C++) | Limited to signal + register dump | Pair with Breakpad / Crashpad integration | | Async call chains | Incomplete stack | Use raygun.trackAsyncCrash() API |

In today's digital landscape, ensuring the stability and performance of software applications is crucial for delivering a seamless user experience. One tool that has gained significant attention in recent years for its crash diagnostics capabilities is Raygun. In this post, we'll explore the features and benefits of Raygun's crash diagnostics, and how it can help developers identify and resolve errors efficiently.

Raygun’s SDK adds ~2–5 ms overhead per transaction when crash reporting is active. For high-throughput systems (>10k req/sec), asynchronous batching prevents blocking. However, during memory pressure scenarios, the SDK may drop crash reports before transmission, leading to false negatives. raygun crash diagnostics
