6 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers. Learn more.
Browser errors were logged to the console

Quick overview:
Installable
Does not use HTTPS

Current page does not respond with a 200 when offline
If you're building a Progressive Web App, consider using a service worker so that your app can work offline. Learn more.

Links do not have a discernible name

Contrast
These are opportunities to improve the legibility of your content.
