Validity
Click the icon in the address bar or press Alt+Shift+V to validate the current page. Results can be seen in Chrome's JS console.
Validity can be used to quickly validate your HTML documents from the toolbar.
Just click the icon in the toolbar to validate the current document without leaving the page. The number of validation errors can be seen in the tool tip and the detail can be seen in the console tab of Chrome's developer tools.
Validity also gives you the option to use your own installation of the W3C Validation Service. (For more information on installing the W3C Validation Service see the documentation at http://validator.w3.org/docs/install.html).

Its super and it can run offline too, works with web designs locally via localhosts too. I'm using since 2017, and I found it very right? Never faced a single problems. Please start it back anyhow?
It stopped working. They must remove it from the Chrome Web Store.

Doesn't work. Complains about character encoding not declared. But it is declared and W3-Validator shows no problems. So: Useless Extension

Lacks an option to ignore certain error/warning types which is important since the official validator flags errors for non-standard attributes which are still VALID under HTML 5. Makes the results very hard to use for anyone using AngularJS or similar on their site.

This helped me a lot, I think I'll use it from now on for all of my projects. It showed me a lot of problems I didn't see before, and the usage of the Console of the Dev Tools is really nice. Really good work, thank you very much for this addon!

Great extension. How can i set rule for validation domain with all third-subdomains? For example: www.example.com test.example.com a.example.com b.example.com a-b-c.example.com

Хрень по-моему, в w3c validator хоть какой-то кусочек кода показывают - тут вообще только строка и столбец. Ну и что мне делать с этим, если у меня html сжатый в одну строку, искать 5456 столбец? Как? Копировать в редактор и смотреть столбец? Короче бесполезное приложение, надеялся на какую-то интерактивность, типа подсвечивание на странице "view-source:", раз устанавливается как приложение в бразуер - но нет. w3c validator online выполняет те же функции, да еще удобнее.
Doesn't show where the error in the source file is. Doesn't work properly with local files which is main reason for using something like this. For non local files just run it through validator.w3.org and it will give you far more useful output

Good app, but it is too week... 1. It does not display, where is error occured. The message in console is not informative.. just number of line.. 2. It can not work with local pages (file:// ...) Seems, like this app is just a wrapper around https://validator.w3.org
