Your site's speed, on watch around the clock
Vita is an always-on Core Web Vitals agent that watches LCP, INP, CLS and TTFB on every page and device. It marks every notable change, good or bad, and tells you where, when and why.
Your page speed moves every day.
Most of it is noise.
Vita calls only the real ones.

It tells you why.
Regressions don't wait for your next audit
A new script, a heavier template or a slow device can drag one page down for weeks while the site-wide score still looks fine. Vita is there the moment it starts.
Always-on monitoring
Vita watches LCP, INP, CLS and TTFB on every page and device, around the clock. Slow templates and low-end phones can't hide in a site-wide average.
Every notable change, both ways
Regressions show up in red, improvements in green, on one 90-day timeline - so you also see which fixes actually worked.
Alerts with context
When a metric really slips, Vita emails you the affected page, the metric, when it changed and the likely cause - not just a red number.
Built to hand off fixes
Vita runs on the same Uxify snippet as the other agents, so a regression can go straight to the agent built to fix it.
Every notable change, on one timeline
Vita ignores the day-to-day noise and marks only the changes that matter, in both directions. Open any of them and you have what you need to act.
- Regressions in red, improvements in green
- The page, device and metric, before and after
- When it happened
- What most likely caused it

Every bar is a notable change on one metric and device. Open any of them to see the page, when it happened and the likely cause.
From the first slip to the right fix
Watch
Once the Uxify snippet is on your site, Vita measures LCP, INP, CLS and TTFB from real visitors on every page and device.
Detect
When a metric moves on one page or one device, Vita marks it as a notable change before it disappears into the site-wide average.
Explain
Each change comes with the page, the metric, when it happened, before and after, and what most likely caused it.
Hand off
Where an agent can fix it, Vita hands it over - an INP regression, for example, is the job INProve was built for.
Vita works alongside INProve, Navigation AI and Carter on one snippet. See the full agent lineup.
Most common questions
What is Vita?
Vita is Uxify's always-on Core Web Vitals agent. It monitors your site on every page and device, marks every notable change - regressions and improvements - and tells you where it happened and what changed before a problem spreads.
Which metrics does Vita monitor?
The three Core Web Vitals - Largest Contentful Paint (LCP), Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS) - plus Time to First Byte (TTFB), which often explains a slow LCP. Google considers a page good when LCP is 2.5 seconds or less, INP is 200 milliseconds or less and CLS is 0.1 or less.
What counts as a notable change?
A shift in a metric big enough to matter for a page or device, in either direction. Day-to-day blips are ignored as noise. Regressions are shown in red and improvements in green, each with the before and after value, so you can see what broke and confirm what your fixes achieved.
Do I need to install anything new?
No. Vita runs on the same single Uxify snippet as Navigation AI, INProve and Carter. If the snippet is already on your site, you can switch Vita on from the dashboard.
Can Vita fix the problems it finds?
Vita's job is to catch and explain changes. Because it shares the Uxify setup with the optimizing agents, it can hand a problem off to the agent built to fix it - for example, INProve for slow interactions.
