Benchmark your site against your competitors

Knowing which of your competitors are faster than you is a fantastic way to get web performance buy-in throughout your organization. Bonus: It's super easy to set up! Extra bonus: You can also generate great visualizations – like side-by-side videos and filmstrips – to share with your team.

Correlate web performance with user experience

User engagement charts let you use your own data to understand the impact of page slowdowns on your site's bounce rate.

Correlate performance

Measure when your most important content renders

Not all pixels and page elements are equal. Measure the rendering speed of the content your visitors care about most. Headlines, hero images and any other elements you choose.

Content rending

Track the impact of web performance on your business metrics

How do page slowdowns affect your business? Track any metrics you want – including cart size, A/B tests, and conversion rate.

A/B performance tests

Test continually

Use the SpeedCurve Deploy API as part of your CI/CD process, and track the impact of code changes between deploys. Track pixel level changes to your UX with visual diffs.

Visual diffs and deploys

Create performance budgets and get alerts

Performance budgets and alerts are a vital tool in your web performance toolbox. They take the hassle out of monitoring your pages by notifying you when your most important metrics cross a defined threshold.

Performance budgets

Debug web performance issues at the page level

Find and fix what matters most. Along with Google's Lighthouse & PageSpeed Insights audits, we'll give you a curated list of performance rules, stacked and color-coded in their order of importance. Tick them off and improve your speed.

Performance recommendations

See the performance impact of ads and third parties

The scripts and stylesheets that come with ads, analytics, and social widgets can block the main content on your pages from ever being seen by your users. To help identify this issue, we created third-party waterfall charts to show you where your roadblocks are.

Compare synthetic and RUM data
