Pay for what you
switch on.
Five monitors. Switch them on per site, right here, and the bill adds itself up. Nothing recurring.
Nothing is switched on, so there is nothing to price. Pick at least one line.
$4.80 per site, per monthMix them per site inside the app. For example, Visual Changes and Renewals on a brochure site, and everything on for a shop.
Prices are in US dollars, and the price you see is the price you pay.
No card needed. Two weeks of full monitoring on your first site.
Top up. Then forget it.
You buy credits up front, and each site spends its own once a day for whatever it has switched on. One credit is one cent, so the prices above are the arithmetic you already did.
Credits do not expire while your account is open.
Within 14 days of buying a pack, its unspent credits refund for cash at what that pack charged for them.
Prices are in US dollars, and the price you see is the price you pay.
What each line actually buys.
There are no plan tiers. What moves the price is how many sites you run and which monitors each one has on. Reporting, your team and your history are not charged separately.

Frequently asked questions
New accounts start with enough credits to run one site with every check switched on for about two weeks. No credit card required.
Monitoring stops for the sites that were still switched on, and you are warned on the way down rather than after the fact. Your dashboard, your history and your past reports stay where they are. Add credits and the checks pick up again as soon as the next one is due, which is often the same day.
No. There is no subscription and no card kept on file. You buy credits when you want them, and each site draws its own down once a day for whichever monitors it runs. Credits do not expire while your account is open.
One hostname is one site. For example, example.com is one site. SiteLetter automatically discovers and monitors up to 15 of your most important pages from your sitemap.
SiteLetter automatically selects your top 15 pages by importance (homepage and top-level pages first). Choosing which pages those are is not available today.
Yes, per site, whenever you like. Switch a monitor off and that site stops paying for it from the next day. Switch it back on and it starts again. Page Scores and Content Health run on the daily page visit Visual Changes makes, so switching Visual Changes off switches those two off with it. There is nothing to cancel, because there is nothing recurring.
Within 14 days of buying a credit pack, that pack refunds the cash value of its unspent credits, priced at what that pack charged for them. Monitoring already delivered is kept and paid for.
Yes. Send alerts to any combination of email addresses and Slack channels via Incoming Webhooks. An email destination has to already be in your organisation address book, which today means your own team.
