HTML Validators

Wolfram Kriesing - April 26, 2020 - tagged with: #html #tidbit

Various HTML validator I found:

validator.nu seems to be the same used at validator.w3.org. Describes itself as "Validator.nu is validation 2.0".
Structured Data Linter, linter.structured-data.org "The Linter understands the microdata, JSON-LD and RDFa formats according to their latest specifications." they say
yandex's Structured data validator "it also checks if the markup meets the requirements of Yandex's services".
Bing Markup Validator requires a sign-in and than it "shows the markup we’ve discovered, including HTML Microdata, Microformats, RDFa, Schema.org, and OpenGraph".
Google's structured data testing tool verifies the schema.org (structured data) validity, I assume they validate as it is relevant for their search engine.
