Maildev
Maildev is a simple, self-hosted SMTP server designed for testing and debugging emails in development environments. It captures all outgoing emails and provides a web-based UI to view, inspect, and test them. Maildev supports real-time email updates, allowing developers to see emails as they are sent. It also includes an API for programmatic access to emails and supports multiple inboxes for testing different email scenarios. Maildev is lightweight, easy to set up, and works seamlessly in local development and CI/CD pipelines.
