Nevision — One script. Replay, errors, uptime, metrics.

Session replay, JavaScript error tracking, uptime monitoring, Core Web Vitals, web analytics, and server metrics — in a single script under 1KB gzipped.

The Observability Problem

Sentry catches your errors. LogRocket records your sessions. Datadog watches your servers. Plausible counts your visitors. Four tools, four scripts, four bills, four dashboards.

When something breaks, you bounce between tabs trying to correlate the error to the session to the deploy to the traffic spike. The context is split across vendors that don't talk to each other.

Nevision puts it all on one page. One script, one dashboard, one bill — and full context the moment something goes wrong.

What Nevision Does

Session Replay

Watch sessions exactly as users experienced them — 60fps full-DOM reconstruction, including hovers, clicks, and form input.

Error Tracking

Catch JavaScript errors before users report them. Auto-grouped by stack trace with source map support and the session replay attached.

Uptime Monitoring

Minute-level uptime checks from multiple regions. Email alerts the moment your site goes down — no extra service to wire up.

Core Web Vitals

Real-user LCP, INP, and CLS broken down by page, device, and country. See exactly where your performance budget is leaking.

Web Analytics

Visitors, page views, bounce rate, devices, browsers, referrers — without installing a second SDK or breaking your CSP.

Logs & Server Metrics

Structured backend logs and real-time CPU, memory, and request metrics — so frontend and backend issues live in one place.
