Development licenses are provided for free with the purchase of one or more BrowserHawk licenses for use on production servers.

Please note that BrowsrHawk development licenses contain the following restrictions that make these licenses unsuitable for production use:

• Development licenses will only allow BrowserHawk to process up to five unique user agent strings. A user agent string is a unique string transmitted by each browser to identify itself.
• If more than five user agent strings are processed, BrowserHawk will cause a 10 second delay before the requested web page loads. In addition, a warning notice is displayed in the browser stating that the allowed usage has been exceeded, and that the site will resume in 10 seconds.

  Once resumed, one of the other five user agents processed earlier is "bumped" from the list and the last user agent string processed is added to the allowed list. This process repeats itself as new user agent strings beyond the fifth one are processed by BrowserHawk.

• Information about your license and serial number are transmitted in the page headers. This information of course is not publicly accessible when used on private development machines as this license is intended for.

Rarely do developers test their sites during development with more than five different browsers so these restrictions typically will not be seen at all during development.
