Build fast, efficient websites and web apps

Ensure your development efforts lead to high-performing, reliable websites - without the guesswork.
Performance is everything

Great developers prioritize speed and efficiency

You work hard to build websites and apps that are fast, responsive, and user-friendly. But if your site slows down due to bloated scripts or unoptimized assets, your users will feel the pain. PageVitals ensures that your code stays optimized, giving you real-time insights into performance.

With instant alerts, you'll know right away if something breaks - via email, Slack, Teams or a custom webhook - so you can debug and fix issues before they affect users. Stay ahead of the game by catching problems early, whether it's a slow-loading page or a problematic third-party script.

Stay on top of every script marketing adds

We know marketing means well, but dropping third-party scripts all over the website without consulting you can wreak havoc on performance. The good news? You'll no longer be in the dark when this happens.

PageVitals monitors your site around the clock, alerting you immediately when a new marketing script starts slowing things down. Whether it's a tracking pixel, a new ad tag, or another slow-loading script, you'll know right away. This lets you step in quickly to address performance issues before they affect user experience or conversions.
