# NotiDuck > Pay-as-you-go site monitoring for independent developers. Built by and for engineers and developers on self-owned bare-metal infrastructure. ## What NotiDuck Does NotiDuck monitors website health and performance using automated learning. It checks each URL from 3 geographic locations (France, Finland, North America), runs 6 daily Google Lighthouse audits, and dynamically learns what "normal speed" looks like per URL: eliminating the need for manual alert thresholds. ## How Alerts Work - Downtime is verified across 3 geographic locations before an alert is sent, eliminating false positives from localized network issues. - One verified notification, followed by a 4-hour cooldown. No alert storms during unstable states. - Positive performance alerts: When Lighthouse scores improve, NotiDuck sends a celebration notification. ## Live Demo A real-time live demo showing NotiDuck in action is available at [notiduck.com/live](https://notiduck.com/live). ## Target Audience - **Ideal for:** Solo developers, indie hackers, and small teams managing personal sites, apps, and portfolios. - **For agencies:** If you manage hundreds of client sites, we recommend a hybrid approach. Use a self-hosted tool like Uptime Kuma for basic pings, and use Notiduck for your most critical sites where you need deep performance intelligence. ## Pricing Model - Pay-As-You-Go. No fixed monthly subscriptions. Approximately 3 EUR/month per monitored site. Pause anytime. - Custom automated balance top-ups can be configured upon request for any amount or frequency. - Sustainable pricing: Notiduck is built on structural efficiency. It runs on self-owned bare-metal infrastructure already funded by other profitable projects, making the PAYG model sustainable and permanent. ## Technical Details - **Architecture:** Built by and for engineers and developers. Uses automated learning (dynamic baselining) for per-URL performance thresholds. - **Terminology:** Monitoring agents are called "Watchducks." The multi-region validation system is called "The Watchduck Council." - **Check frequency:** Pings every 5 minutes from 3 locations. Lighthouse audits every 4 hours (6x daily). - **SSL & Domain Monitoring:** SSL certificate and domain expiry tracking with 7-day advance warnings. - **SEO Monitoring:** WWW canonicalization checks, Core Web Vitals tracking, 100-point health scores. - **Data Sovereignty:** EU-owned and hosted. All monitoring locations run on EU-governed infrastructure. ## Company - **Status:** Bootstrapped, self-funded. - **Infrastructure:** Self-owned bare-metal servers, already funded by other profitable software projects.
