Why BugSpray Outperforms Legacy Recorders
Unlike older recorders that rely heavily on continuous DOM serialization on the main thread, BugSpray moves compression and serialization into a dedicated WebAssembly WebWorker.
This guarantees that your web application maintains a smooth 60 FPS frame rate and optimal Interaction to Next Paint (INP) scores.
