Hi HN!<p>We posted a Show HN 73 days ago about extension.dev. In the 73 days since our last post, we interviewed 70 of you over Zoom. With your help, we designed, built, and shipped V1 of extension.dev. We are now ready to help everyone build and share their own custom extensions.<p>V1 of extension.dev focuses on helping engineers at companies build Chrome extensions to make their teammates more productive. We've seen early users create context-aware Sidebars to reduce context switching, add buttons to their internal dashboards, and even modify the DOM by removing intrusive elements.<p>We are excited to invite the HN community to join the developer preview before we make a public release!<p>Kevin, Will, James
