Page Speed Analyzer

Measure TTFB, total payload size, and core web vitals instantly. Identify exactly what's slowing your websites down.

Public Cloud APIs

When analyzing a single URL, our platform delegates the massive computing power required for rendering to public Cloud APIs. This results in incredibly accurate Core Web Vitals with zero latency added to your experience.

Headless Chromium Engines

When analyzing massive CSV files, we utilize dedicated Python workers equipped with Playwright headless browsers. They physically navigate to every URL in the background, intercept network payloads, and calculate exact loading times.

Frequently Asked Questions

TTFB stands for Time to First Byte. It measures the milliseconds it takes for a user's browser to receive the very first byte of data from your server after requesting the page. A high TTFB usually means a slow server or missing caching layer.

To guarantee zero impact on your local network, our platform dispatches a secure request to our high-performance server engines. This simulates a real desktop environment loading your page using headless Chromium, returning highly accurate metrics without external API rate-limits.

To prevent rate-limits, uploading a massive CSV will transfer the workload to our backend servers. We dynamically spin up headless Chromium browser instances using Playwright to physically load every URL, record the network traffic, and generate your exportable CSV.
