One integration. Complete visibility. Spanary cuts through the clutter with opinionated, integrated insights — so you can focus on building, not debugging dashboards.
The Lens SDK
An intent-based API that covers every angle — from user clicks to system health. Most tracking is automatic. You just focus on shipping.
Track UI behaviors, clicks, and navigation. Auto-captured clicks, page views, and form submits — manual tracking only when you need custom events.
Track milestones like "Order Completed" or "User Signed Up". Entity + Action pattern for consistent, queryable business analytics.
Catch errors with automatic normalization and stack trace extraction. Unhandled errors captured automatically — use this for explicit handling.
Track internal operations — HTTP requests, background jobs, cache operations. Full infrastructure visibility for backend services.
LCP, INP, CLS, TTFB — all Core Web Vitals tracked automatically. Route-based metrics for SPAs. Custom timing support when you need it.
Drop-in plugins for popular frameworks. HTTP requests and errors tracked automatically. Optional fetch wrapping for external calls.
See It In Action
Users, errors, and performance — all connected. No switching between tools.
That slow checkout? See the error rate spike, the users who bounced, and the server load — all in one view.
Why Spanary
Great observability isn't about more features — it's about fewer, better insights. We're opinionated about what you need to see so you can stay focused on building.
Stop stitching together analytics, errors, performance, and events across 4 different tools. Lens gives you the full operational story in one place.
No enterprise bloat. No sales calls. No feature walls you don't need. Just the right observability for teams who ship fast and stay lean.
The Difference
We believe most teams drown in dashboards they never look at. Spanary surfaces signals and filters noise.
