A rising tide lifts all boats. -- United States President, John F. Kennedy (borrowed from the New England Council)

Inspired by the proverb “A rising tide lifts all boats”, when we lower the barrier of entry to writing and choosing quality code for enough people, it will lift the quality of code across the whole WordPress ecosystem. Tide’s vision is to make it easy to improve the quality of code throughout the WordPress ecosystem and help WordPress site owners make better choices about plugins and themes.


Tide is an automated tool to provide insight into WordPress code and highlight areas to improve the quality of plugins and themes.

Tide services are responsible for the following:

  • The Sync Server polls the API's for themes and plugins to process and writes them to a queue.
  • The PHPCS Server reads messages from a queue and runs reports against both plugins and themes, then sends the results back to the Tide API.
  • The Lighthouse Server reads messages from a queue and runs Google Lighthouse reports against the themes only, then sends the results back to the Tide API.
