Why It’s Awesome

This new WordPress-specific check is a quick, automated report that detects common problems before launch. You can also use WordPress Launch Check to monitor the health of your site post-launch. The result is improved site speed, performance and reliability—no installation required. It’s also in beta, so please send us your feedback after testing it out in the wild.


  • Detects whether your Wordpress site is properly set up for session handling and provides a fix if necessary

  • Looks for insecure and vulnerable code using WordPress’ scan database

  • Ensures caching is configured properly for better performance

  • Flags plugins that are known to cause problems in cloud environments

The Pantheon Dashboard

Sharing the Love

Here at Pantheon we’ve always been big proponents of open source and the awesomeness that is shared knowledge. Because of this love, we’re sharing WordPress Launch Check with the world as a WP-CLI plugin available on GitHub. Power users rejoice!
