Website Validator

This program validates the html of an entire website at the press of a button. It's free. No ads, no tricks. I made it because I needed it at work and thought I might as well share it with others.

Download Website Validator
v. 1.1.1
(0.5 MB)
for Windows (requires Java 8)

Validating a small website

You could use W3C Markup Validation Service url: https://validator.w3.org/

  1. Download and install Website Validator (WV)
  2. Start WV, using https://validator.w3.org/ as Validator url

Validating a large website

You should install vnu, running it on your computer in order to avoid getting black listed at the W3C Markup Validation Service due to heavy traffic:

  1. Download the latest vnu<version>.jar (zip) from GitHub: Nu Html Checker (v.Nu)
  2. Extract the zip-file to a folder on your computer.
  3. Create a file called run-vnu.cmd in the same folder and put this command inside it:
    java -cp vnu.jar nu.validator.servlet.Main 8888
  4. Double click/run run-vnu.cmd
  5. Point your browser to http://localhost:8888 to make sure it runs
  6. Download and install Website Validator (WV)
  7. Start WV, using http://localhost:8888 as Validator url

Report

After validation a report is displayed and saved in c:\users\<username>\Website Validator report. Make sure to copy reports you want to save, otherwise it will be replaced the next time you use WV.
