Modify, measure & monitor.
SideQuick helps you quickly prototype any change on any live URL effortlessly, measure its impact whilst following experts best practices, and monitor your site's Core Web Vitals to prevent surprises.
Modifiers
Change anything on any live URL – effortlessly.
Quickly prototype any changes you want to any live URL, and see whether it looks good, it works as expected, and/or it improves your intended metric, without wasting any time on a proof of concept.
Original vs Modified
Get 2 URLs in return – one with all the modifications enabled and the other without any changes applied. 1 means on, 0 means off – both go through the proxy to ensure a fair comparison.
+40 free recipes to choose from
Add or replace any HTML in the page, see if inlining CSS improves First Contentful Paint, confirm whether a 3rd-party script is affecting INP, and many more.
Use your own tools/workflows
Open them on your own browser, your personal devices, your favourite lab tools, or even discuss them with your team. Validate the change works as expected or continue iterating until it does.
Write your own
Subscribers can write and deploy their own custom code with all the flexibility and none of the awkward fiddling to set things up properly.
Measurements
Run tests like experts do
Check the performance of multiple URLs in one fully-customizable dashboard. Pull data from Google Chrome User Experience, Page Speed Insights (Lighthouse) and our own scriptable Puppeteer (for user journeys beyond page load).
+50 widgets and counting
You can simply copy and paste from our docs directly into your own dashboard.
Beyond just page loading
Use Chrome DevTools Recorder to record user journeys that can be tested using Puppeteer. You can scroll and interact with elements to profile INP/CLS beyond just the initial page loading.
Build your own dashboards
A single performance score based on lab conditions can confuse people. Create your own score gauges (f.e. using CrUX data) or none at all, depending on what you/your clients should focus on.
Share dashboards with anyone
Make your dashboards public and anyone can start using them on their own measurements.
Monitors
Set up alerts for Core Web Vitals
Track your website's Google Core Web Vitals with customizable dashboards. Get alerted if any regression slipped through and it's impacting your users.
A table to rule them all
Track multiple sites (and/or multiple pages inside a single site scanning its sitemap) in a table that refreshes data from CrUX API every 24 hours.
Build your own dashboards
Use any of our +50 widgets to focus on the specific data you're interested on.
Share dashboards with anyone
Make your dashboards public and anyone can start using them on their own monitors.
Configurable alerts
Set up email notifications for any Web Vital. Get notified when metrics cross thresholds you define, like any Core Web Vital stops passing or mobile LCP > 1500ms.
