For years the stack was simple: an analytics tool for behavior, and Sentry for errors. But when your analytics SDK already sits in every session, capturing errors there too starts to make a lot of sense. So do you still need a dedicated error tool? It depends on what you actually do with errors.
What Sentry does well
Sentry is excellent at the engineering side of errors: grouping, stack traces, source maps, release health, alerting. If your job is to fix the bug, it gives you what you need to reproduce it.
What a stack trace doesn’t tell you
A stack trace tells you what broke. It rarely tells you what the user was doing, where they came from, which funnel step they were in, or whether the error actually cost you a conversion. That context lives in your analytics — a different tool, a different tab, a different mental model.
Errors as analytics events
When errors are captured by the same SDK as your product analytics, an error becomes just another event on the user’s timeline. You see the clicks leading up to the crash, the device and location, the identified user, and the funnel it interrupted. Nohmo auto-captures JavaScript errors, unhandled promise rejections, failed fetch/XHR requests, and native app crashes — each tied to the session that produced it.
When you still want dedicated error tooling
Be honest about your needs. If you rely on deep release-health dashboards, per-commit regression tracking, or sophisticated alerting workflows, a specialist tool still earns its place. For most product teams, though, the goal is simpler: know that something broke, for whom, and in what flow.
The consolidation case
Running analytics and Sentry side by side means two SDKs, two dashboards, and two invoices. If your analytics already captures errors with full user context, one of those tools is doing work the other could absorb. Consolidation isn’t about “errors as a feature” — it’s about seeing every crash inside the journey that caused it, and paying one flat bill for the privilege.
