About Localhost Banner Alert

Localhost Banner Alert is your companion for local development! This Chrome extension adds a visible banner to your browser to remind you when you're browsing localhost sites. The banner is displayed if the URL of the current tab contains one of these elements: * localhost * .local * 127.0.0. * .test You can manage several parameters. Simply click on the extension button and then on "Go to settings": * Banner enabled: Yes / No * Banner Text : the text on the banner *(default: Localhost)* * Banner Position : Top Left / Top Right *(default)* / Bottom Left / Bottom Right * Banner Theme : Orange *(default)* / Red / Yellow / Blue / Purple / Green * Exclude URLs : fill in the URLs that should not have the banner. One URL per line without http(s). The extension does not collect any user information or other information. Only extension-related parameters are stored.
