About Hansel by Seedling
Hansel by Seedling is a self-hosted, privacy-focused alternative to traditional email services like Gmail and Outlook. Designed specifically for teams that prioritize ultimate security and absolute data ownership, Hansel runs entirely on your own server. This guarantees that your email database remains completely under your control, ensuring no external company or provider can ever lock you out of your communications.
The platform is built with security at its core, utilizing device-side encryption to ensure that messages are encrypted before they leave your device, meaning the platform itself cannot read them. Additionally, Hansel implements an architectural solution to spam: without your cryptographic key, unauthorized messages simply cannot arrive on your server.
Beyond standard email functionality, Hansel provides a comprehensive suite of collaboration and productivity tools, including encrypted messaging, custom domain support, an integrated calendar, notes, and robust enterprise admin tools.
