ZeroDrop

ZeroDrop is an email testing infrastructure that provides instant, disposable inboxes for developers to verify OTPs, magic links, and other authentication emails directly from code. It solves the problem of manually checking throwaway inboxes or setting up local email servers like MailHog. The service targets software developers and engineering teams building auth flows, particularly those using test frameworks like Playwright, Cypress, and pytest. It is positioned as a cloud-based alternative to local email testing tools, offering no Docker, no signup, and SDKs for multiple languages, with sub-second email delivery via SSE.
