This means you can define your conversion funnels retroactively in the dashboard using data that was already captured, without a single new deploy. Get started at glitchreplay.com #glitchreplay #sessionreplay #errortracking #bugmonitoring #conversionrate #productanalytics 2/2

Every phantom failure is a customer who tried to give you money and couldn't, but because the stack trace only pointed to the final API call, the real cause remained invisible for weeks. #glitchreplay #errortracking #sessionreplay #bugmonitoring #developerproductivity #softwareengineering 2/2

By the numbers — session pruning:
- 3 days: retention for sessions not linked to an error
- Tier-based: retention window for error-linked sessions

It turned out to be a specific interaction with the browser's autofill layer that didn't trigger a crash, but malformed the payload before it ever hit the API. #glitchreplay #errortracking #sessionreplay #bugmonitoring #webdev #iossafari 2/2

Field data is the aggregated experience of real users over the last 28 days, accounting for real-world device throttling and network latency that a clean lab environment simply cannot simulate. #glitchreplay #errortracking #sessionreplay #webperformance #corewebvitals #frontendperformance 2/2

What is the most 'works on my machine' bug you've ever encountered that only decided to appear once the code hit a production CDN or a specific mobile browser?

When you're tracking a new user flow, do you prefer starting with broad tags to define funnels later, or do you go straight to manual instrumentation for precise, named steps from day one?

You end up with an unresolved trace exactly when you need the stack trace most to fix a production outage. #glitchreplay #errortracking #sessionreplay #sourcemaps #observability #debugging 2/2

If your site feels fast in DevTools but ranks poorly in Google, you're likely seeing the gap between lab simulations and actual device thermal throttling. #glitchreplay #errortracking #sessionreplay #bugmonitoring #webperf #rum 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

Two requests in the log, two completely different root causes depending on what the user saw. The replay was the only artifact that could disambiguate. #glitchreplay #sessionreplay #errortracking #bugmonitoring #uxdebugging #frontend 3/3
