Web Performance Analysis Platform
Submit a URL. We crawl every page, run Lighthouse on each, and give you a complete performance report with scores, Core Web Vitals, and actionable recommendations.

What we measure
Every page on your site is analyzed across the four core Lighthouse categories.
Loading speed, interactivity, and visual stability. We measure LCP, CLS, INP, and TTFB for every page.
ARIA attributes, color contrast, keyboard navigation, screen reader compatibility, and semantic HTML structure.
HTTPS usage, safe JavaScript, image aspect ratios, deprecation warnings, and modern web standards compliance.
Meta tags, crawlability, structured data, mobile-friendliness, and search engine optimization fundamentals.
How it works
Four automated steps. No configuration needed.
Enter your website address. That's all we need to get started.
Our crawler discovers every page using breadth-first search with Playwright.
Each discovered page is analyzed individually with Google Lighthouse.
Get aggregated scores, per-page breakdowns, Core Web Vitals, and recommendations.

Capabilities
A complete toolkit to monitor, analyze, and improve your websites.
Automatic breadth-first crawl with Playwright discovers every page on your site, following internal links.
LCP, CLS, INP, and TTFB measured for every page. See which pages drag down your overall performance.
Track how your scores evolve over time. Detect regressions early and measure the impact of your optimizations.
Compare two scans side by side. See exactly what changed between deployments or optimization rounds.
Set up daily, weekly, or monthly automated scans. Get notified when scores drop below your threshold.
Trigger scans programmatically, fetch results via REST API, and receive webhook notifications on completion.
Deployment
We're building goWebPerf with flexibility in mind. Choose the deployment model that fits your needs.
Run goWebPerf on your own servers — on-premise, VM, or any Docker-compatible infrastructure. Full control over your data, scans, and results. No external dependencies.
Don't want to manage infrastructure? We're planning a hosted version where you can start scanning in minutes, with zero setup required.
