Blit is a tool that lets you take screenshots of websites on a schedule. Try it free.

You can upload your screenshots directly to your cloud storage through Apps. The Slack App allows you to receive your captures in a Slack channel.

To start sending captures as Slack notifications, follow these steps:

  1. Create an App in Slack.
  2. Create a Slack App in Blitapp.
  3. Add your new App to any capture.

Blitapp takes all captures in high resolutions, up to 2,000px by 20,000px. Full-page screenshots usually don’t fit on a screen. Therefore, your web browser scales down the image to fit the screen. A full-page capture would look like this in your browser – a small image with a plain black background:

With the automation steps, you can now log in to a website and take multiple screenshots of different pages. The automation steps can handle complex login over multiple pages.

In this post, we’ll show you how to log in to a website, Browshot, and take a screenshot after authentication.

To log in from the home page of, a user must click on *Login*. This displays a login form where the user has to enter his username and password. Then the user clicks on "Login" to obtain access to his dashboard.

Find the element to interact with

We're going to build the different steps to log in; then we'll navigate to a different page in the dashboard and take a screenshot. The hardest part of the process is to get the identifier (called CSS selector) for each element we want to interact with: the button to click on, the input box in which to enter our username, etc. In order to find this identifier, we need to use the Developer Tools from your web browser. Press F12 to open the Developer Tools. Navigate to In the Developer Tools, click on the mouse cursor in the top left corner (highlighted in red below). more...

With Blitapp, you can inject JavaScript in any page to log in, click on elements, etc. To expand the range of possible interactions, and simplify them, we have added automation steps.

On this blog, we will post several examples using automation steps, including:

  • Complex login to a website
  • Log in to a site and take screenshots of multiple pages
  • Take screenshots of a carousel with all the elements
  • Select multiple elements in a page

Automation steps

The automation steps describe the list of commands that the browser must execute. Unlike the injected JavaScript, these steps can be carried out over multiple pages and can generate multiple screenshots. Each step contains:

  • a command:
    • type: type text, like a username or password
    • click: click on an element
    • javascript: execute and JavaScript
    • sleep: wait for a number of seconds
    • navigate: navigate to a new URL
    • screenshot: take a screenshot of the current screen, page or specific element
  • element (optional): a CSS selector targeted by the command, for example, the input field to type a username, the element to click on, etc.
  • value (optional): the number of seconds to sleep, the text to type, the URL to navigate to or the JavaScript code to execute

To remain compliant with our e-mail provider, we must block invalid e-mail addresses, addresses that have bounced, etc. Every day, we get reports about such e-mail addresses and add them to our blacklist. These e-mails cannot receive any notification from us, including information about a capture, a password reset, etc.

Now you will see a warning if your account e-mail address has been blocked and if any e-mail recipient of your capture is on our blacklist. You can open a support ticket to solve the issue and get the e-mail whitelisted again.

If your own account e-mail address is blacklisted, you will find this warning at the top of each page and under Account:

Your e-mail is blocked

If a capture contains an e-mail address that is blocked, you will see a similar warning at the top and bottom of the capture page:

Your e-mail is blocked

Check that the e-mail address is spelled correctly, and contact the owner to determine whether they recently had an issue (e.g., mailbox full, change of e-mail, etc.) or whether they have blocked messages from
