Nerd Crawler was built because we wanted to know when new original comic art was ready to buy from our favorite artists and dealers, but we were wasting so much time refreshing sites so we wanted to find a way to automate this. We developed a proprietary technology to crawl for updates on our favorite original comic art sites, and now we're making it available for other comic art fans to use!

Yes! Nerd Crawler will always have a free plan that you can use to crawl up to 3 pages once per day. If you'd like to crawl more than 5 pages or increase frequency of crawls, you can upgrade to one of our paid plans.

A "crawl" is defined as every time we check a website to see if there's an update. When we crawl and detect an update to the page you wanted us to crawl, we'll email you. You can also receive text message alerts when an update is detected by upgrading to any of our paid plans. When you tell us what site page you want us to monitor and how often you want us to check it, you've made a "crawler".

Free users can crawl a page once per day. If you upgrade to a paid plan, you change the frequency to one of the following: Every 1, 5, 10, 20, or 30 minutes, Every 1, 3, 6, or 12 hours, Every Day, Every Week, or Every Month.

Yes! You can manually test any crawler at any time when you create an account. Test crawls are always free no matter what plan you're on. Test crawls may not send an alert if there is no update detected.

This can happen for a variety of reasons including 1) items on the page were edited, removed, or sold out but no new items were added and 2) an update was detected but someone already bought the new item and it was removed before you visited the site. If you think there's a bug with your crawlers, please email us right away at hello@nerdcrawler.com.

Yes! Please email your site request to hello@nerdcrawler.com. Our product is built by comic art fans so we'd be happy to investigate and add your site if possible.
