You can sign up and use Simply Testable for 30 days without having to enter any credit card details.
If you provide your card details before your trial ends you will continue with the plan you chose. You will be billed monthly from the end of your trial.
If you don't provide card details you will be downgraded to a free basic account with the option to upgrade to a paid plan at your convenience.
Performing a HTML validation, CSS validation or JSLint analysis on a single URL requires one credit.
Performing all three on a 10 page site would require 30 credits.
The number of monthly credits you have available depends on the plan you choose.
Credits don't roll over from one month to the next.
All plans are month to month.
You can cancel at any time. If you cancel during a billing cycle (which is quite likely unless you time things very well) we will refund you for the remainder of the month not yet used.
