Developer toolsListed Nov 1, 2026
Visit mailpit.axllent.orgMailpit catches every email your app sends during development and shows it in a clean web inbox, so nothing reaches real users. It checks HTML rendering, links and spam scores, and offers an API for automated tests. It ships as a single small binary or Docker image and is maintained by an independent developer.
