Frequently asked questions

How long does a screenshot take?

Usually 2 to 5 seconds, depending on the page. Pages get 15 seconds to load.

Can it screenshot pages behind a login?

No. The browser isn't signed in to anything, and cookies or credentials can't be passed in.

Is there a free tier?

Yes. 10 renders per day per IP without a key, or 50 a day with a free API key from your Cuelark account. There's no paid plan.
