Tommy ParnellI've been using @SpeedCurve for only about a week, and I'm 100% sold. If you really care about front end #performance, get your boss/company to pay for this tool. Holy crap is it amazing. I'm just glad I can easily graph my #lighthouse scores over time.
Simão FreitasSpeedCurve just keeps on giving. Just helped me find another big performance bottleneck. This tool is a no brainer ❤️
Tim KadlecI love @SpeedCurve for correlating RUM data to business metrics. They have some out of the box stuff around bounce rate, and it's easy to add custom business metrics to graph and track.
Andrew Del PreteStill getting a kick out of SpeedCurve. The individual result views are fantastic. They'll even load in Chrome Dev Tools and WebPageTest.
