What is Wattspeed?

Wattspeed is a synthetic monitoring tool that helps you to discover the low-hanging fruit for improving your web pages. If you're a developer, marketer or merely own a website, Wattspeed can help you measure and monitor the performance of your web pages.

What can I do with Wattspeed?

Using Wattspeed you can monitor your website's performance, page source and security, so you will know exactly what's going wrong with every aspect of your website before anyone else does.

Is Wattspeed FREE?

Wattspeed has a FREE version that allows you to monitor an unlimited number of web pages within a total of 10 snapshots per month. However, the free plan will lack some of the most important features.

What is a snapshot?

A Wattspeed snapshot is a capture of your web page that includes Lighthouse report, page source info (technologies list, HTML validation, DOM size, mixed content and more), CrUX data for the last 12 months and security audit.

Credits explained
One snapshot consumes a variable number of credits, based on its settings. Minimum snapshot requirements are 1 location & 1 device, which account to 1 credit.

Running an on demand snapshot from the United States flag United Stated for mobile will consume 1 credit.
  • Each additional location costs 1 credit per snapshot
  • Each additional device costs 1 credit per snapshot
  • Daily frequency will consume 30 credits (provides 30 snapshots / month)
  • Historical CrUX costs 30 credits for the first time update, 3 credits per month thereafter
Calculation for 3 location, 2 devices, daily frequency and historical CrUX data enabled:
(3 locations * 2 devices * 30 daily update frequency) + 30 CrUX = 210 credits per month
