Know how your site
actually feels
Drop in one script tag. Get Core Web Vitals from real visitors — not synthetic tests. Zero config, privacy-first, from $0/mo.
Everything you need,
nothing you don't
Real user metrics, per-route breakdowns, privacy by default. Built for developers who ship.
Zero config setup
Add one script tag to your site. That's the entire setup. Metrics start flowing in seconds with sensible defaults that work out of the box.
Real user metrics
LCP, INP, CLS, FCP, TTFB — collected from actual visitors on real devices. Not Lighthouse estimates running on a server somewhere.
Route-level insight
Break down performance by URL, country, and device type.
Privacy-first
No cookies. No fingerprinting. No PII. GDPR compliant by design.
Email alerts
Get notified when performance degrades past your thresholds.
Edge-native
Built on Cloudflare Workers. Sub-10ms ingestion worldwide.
Integration
Works in minutes,
not hours
Copy one script tag into your HTML. No build step, no npm package, no framework plugin. Create a project when you're ready for production.
<script defer
src="https://bilis.app/b.js"
data-project="proj_xxx"></script>What you get
- P75, P90, P95 percentile metrics
- Per-route performance breakdown
- Country and device segmentation
- Real Experience Score (RES)
- Historical trends and email alerts
Same metrics. Fraction of the price.
Real user monitoring shouldn't cost more than your hosting.
