Developer Tools FAQ
Do these developer tools send data to a server?
Most tools process data in your browser. The link shortener is the exception because it needs a redirect service.
Can I use generated passwords safely?
Passwords are generated locally and are not transmitted. Use a password manager for storage.
Will HTML minification break my page?
Standard minification is usually safe, but always test important production code before deploying it.
