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 (zip)
version 1.2.1
for Windows/Linux/Mac

Installation

1. Download the zip file
2. Unzip it to a folder
3. Double click the jar file to run it (on Linux you might instead have to run the attached script)

Note: Requires Java

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 (.sh for Linux, .command for Mac) in the same folder and put this command inside it:
   java -Xss1024k -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 your home folder in subfolder "Website Validator report" (in Windows: c:\users\<username>\Website Validator report).
