Palmr is an open-source file-sharing platform designed for secure, efficient, and user-friendly file transfers. Built with performance and privacy in mind, it serves as a robust alternative to services like WeTransfer, SendGB, Send Anywhere, and Files-fm. The platform, currently in version 3, offers features such as password-protected uploads, user management, and integration with S3-compatible storage providers for flexible and scalable file storage. Palmr includes a streamlined interface with accessibility improvements, a built-in configuration panel for easy SMTP setup. Its lightweight design and focus on security make it ideal for both individual and enterprise use, with a simple process for uploading files and managing users. In this step by step guide I will show you how to install Palmr on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Palmr v3.0.0 release.
