What is Wattspeed?

Wattspeed is a synthetic monitoring tool that helps you to discover‌ the‌ ‌low‌-hanging‌ ‌fruit‌ for improving your web pages.

Who is this for?

If you're a developer, marketer or merely own a website, Wattspeed can help you measure and monitor the performance of your web pages.

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.

What is a snapshot?

A Wattspeed snapshot is a capture of your web page that includes Lighthouse scores, technologies list, HTML validation, DOM size, mixed content info, and more.

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
