FreeResend
An open-source, self-hostable email API alternative to Resend, built with Node.js and Express.
Overview
FreeResend is an open-source, self-hostable email API built with Node.js and Express.js, designed to serve as an alternative to commercial email sending platforms like Resend. It empowers developers to manage their email infrastructure directly, providing a programmatic interface to send emails without relying on external vendors. This approach offers greater control over data, customization options, and potentially lower costs for high-volume senders.
The tool works by integrating with an existing SMTP provider (which the user must configure) and exposing a simple RESTful API. Developers can send emails by making HTTP requests to their self-hosted FreeResend instance. While currently focused on core email sending functionality, the roadmap includes features like email templating, analytics, and webhooks to enhance its capabilities and provide a more comprehensive email solution.
