This is the honest, non-marketing version of what breaks when you move high-volume error tracking off a per-event platform, and the dual-write safety net that made the breakage survivable. #glitchreplay #errortracking https://glitchreplay.com/blog/migrating-50m-events-off-sentry 4/4

Real protection requires a zero-trust posture — scrubbing at the ingest edge, server-side, before data ever touches storage. The full article walks through three concrete failure modes and what to do instead. #privacyfirst #errortracking #glitchreplay #errortracking 4/5

Sometimes a thousand events that look different are all the same root cause. When have you had to override the default grouping on an issue, and what was the signal that told you the fingerprint was wrong? #glitchreplay #errortracking #bugmonitoring #errorgrouping #fingerprinting #rootcause 2/2

Where do you draw the line—do you scrub at the SDK level, at ingest, or both? And what's the one field you always strip no matter what? #glitchreplay #privacyfirst #errortracking #sentryalternative #piiscrubbing #dataprivacy 2/2

Replay is extraordinary for frontend and interaction bugs. For race conditions in distributed systems, it's the wrong tool, and pretending otherwise costs you time you don't have. #glitchreplay #sessionreplay #errortracking #distributedsystems #debugging #backendbugs 3/3

The replay shows you the actual visual state the user experienced, and that's usually the whole answer. #glitchreplay #sessionreplay #errortracking #bugmonitoring #frontenddebugging #cssbugs 3/3

By the numbers — source map storage:
- 10 MB limit per map file
- LRU 32 parsed maps cached in-isolate
- Storage path: {project_id}/{release}/{basename}.map
- Re-upload same key: overwrites silently
