Paywall is a free Chrome add-on developed by Mark Crandall. It falls under the category of Browsers, specifically Add-ons & Tools. This handy tool is designed to help users identify paywall sites by displaying the links as "$$$". It also preserves the original text of the link while replacing it with the "$$$" text.

With Paywall, users can easily recognize paywall sites and make informed decisions about whether they want to access the content behind the paywall. This can be particularly useful for users who frequently visit news websites or other platforms that have paywalls.

In addition to identifying paywall sites, Paywall also flags sites that do not work with adblockers. This feature ensures that users are aware of websites that may not function optimally when adblockers are enabled.

It is important to note that Paywall does not in any way circumvent paywall sites or logon restrictions. Instead, it simply serves as a warning that a particular link leads to a paywall site. This allows users to decide whether they want to proceed or look for alternative sources of information.

Overall, Paywall is a useful tool for those who want to easily identify paywall sites and be aware of websites that may not work well with adblockers. Its simple yet effective functionality makes it a valuable addition to any Chrome user's toolkit.
