How often are my sites checked?
Each plan has its own fastest interval, down to one minute on the higher plans. You choose the interval per monitor, up to what your plan allows.
What kinds of things can I monitor?
Websites and API endpoints over HTTP(S) (status code, optional text on the page, response time), server ports over TCP, and scheduled jobs through a heartbeat URL your job calls. The monitor types available depend on your plan.
What is speed monitoring?
A real browser loads your page on a schedule and records the load time, first byte, first paint, largest paint, layout shift, page weight and number of requests. You see the results for desktop and mobile side by side, with a chart over time, and can get an alert when the page gets slower than a limit you choose.
How do screenshots work and how long are they kept?
On the schedule you set for each site, we take a full-page screenshot in a desktop view and in a mobile view and add it to a gallery. The fastest interval and the number of days they are kept depend on your plan or add-on.
Which devices are used?
Every speed check and screenshot is taken twice: once with a desktop-sized browser window and once as a phone-sized mobile browser. Measurements are taken from our servers without network throttling.
Can I buy add-ons on the Free plan?
Yes. Speed monitoring and screenshots are add-ons you can buy on any plan, including Free. They stack with whatever your plan already includes, and you can cancel an add-on at any time.
How will I be alerted?
By email on every plan. WhatsApp alerts are included on paid plans. You get a message when a monitor goes down, reminders while it stays down, and another when it recovers.
Is there really a free plan?
Yes. The free plan includes a limited number of monitors with email alerts, and there is no credit card to enter. Upgrade whenever you need more.
How does billing work?
Paid plans and add-ons are billed through Stripe, monthly or yearly. You can change plan, update your card, download invoices or cancel from your billing page.
Can I monitor any website?
You may only monitor systems you own or are authorised to monitor. Addresses on private networks can't be monitored. See our Terms of Service.
