Sentry implementations for Next.js, React, and backend services — release health, performance traces, and alerts that reach the right engineer.
Sentry for full-stack teams — errors plus performance
Sentry captures exceptions, breadcrumbs, and distributed traces across browser, mobile, and server runtimes. We instrument Next.js App Router, API routes, edge functions, and workers with consistent release tags.
Performance monitoring ties slow transactions to database spans — so "site feels slow" becomes actionable N+1 queries or third-party script delays.
SDK setup, source maps, and release health
Minified production stacks need source maps uploaded in CI — not committed to public buckets. We wire `@sentry/nextjs` with hidden source maps and auth tokens scoped to the project.
Release health tracks crash-free sessions and adoption per deploy — giving product confidence to roll forward or roll back.
Issue grouping, fingerprinting, and noise control
Default grouping floods teams with duplicates. We configure fingerprint rules, inbound filters, and ignored errors (browser extensions, bots) so on-call pages are rare and meaningful.
Ownership rules route checkout errors to payments squad and CMS errors to content platform — via `CODEOWNERS` sync or manual team rules.
Self-hosted Sentry vs SaaS — when each fits
Sentry SaaS (US or EU region) is default for speed and maintenance. Self-hosted suits strict data residency or air-gapped deploys — with explicit ops cost for Postgres, Redis, Kafka, and upgrades.
We document data retention, PII scrubbing, and relay options for hybrid setups sending events through your VPC.
Integrations: Slack, Jira, Linear, and PagerDuty
Alert rules escalate by environment: staging → Slack thread, production → PagerDuty with runbook links. Issue automations create tickets with stack trace, user impact count, and suspect commit.
Cron monitors and uptime checks cover batch jobs Sentry SDKs do not see — scoped when silent failures matter.
Security, PII, and compliance configuration
Before-send hooks scrub emails, credit card patterns, and auth headers. Session replay (if enabled) masks input fields and requires explicit consent configuration on public sites.
