Rocket Validator

I'm the creator of Rocket Validator, a subscription-based site-wide markup validation tool built with Elixir, Phoenix, LiveView and Oban.
Rocket Validator is composed of a main Elixir / Phoenix application that uses Oban to handle the background queue and LiveView to provide real-time updates on the UI. It communicates with Node.JS services running on Vercel and AWS Lambda and the W3C Validator running on Docker instances to coordinate the web page checks. A JSON API provides tools to integrate into custom client workflows.
Offered as a subscription-based SaaS, Rocket Validator is used by developers, companies, and organizations worldwide, including the Agência para a Modernização Administrativa in Portugal or the Australian Web Awards. [link]
