OP here to introduce my new tool for web developers. Most devs are hopefully familiar with Lighthouse and maybe some other testing tools to make sure your website is configured correctly and follows best practices. Lighthouse is a great start, but it doesn't test everything (DNS records, for example). There are many different tools that check different things, but there wasn't any single tool that brought them all together into one test suite. This is why I built Validbot.com. Its aim is to run a comprehensive suite of tests against a public website to look for mistakes or areas for improvement.

Currently there are over 100 tests with plans to add many more in the near future. It currently tests the domain registration, DNS records, SSL, lighthouse tests, server response headers, meta tags, email authentication (SPF, DKIM, DMARC), Favicons, robots.txt file and more. To check all these things without Validbot you would need to manually run your website through a dozen different testing websites and tools.

Happy to take suggestions or answer questions.
