What is Kurrier
Introduction to Kurrier and how to get your first instance running.
Kurrier is a modern, self-hosted communication hub — a unified interface for email, calendars, and contacts — built for people who want the power and privacy of running their own stack without the complexity of maintaining one.
Kurrier connects directly to your existing providers using open standards:
- Email: IMAP / SMTP / SES / SendGrid / Mailgun / Postmark
- Calendars: CalDAV
- Contacts: CardDAV
This lets you bring any provider, any identity, and any domain into one fast, integrated interface — searchable, synced, and fully under your control.
Kurrier runs entirely on your own infrastructure, ensuring your mail, events, contacts, and credentials stay private. It’s lightweight, API-first, cloud-ready, and designed to fit smoothly into personal setups, multi-domain environments, or fully custom workflows.
So whether you're looking for a simple unified inbox, a private Google like experience, or a way to manage multiple email identities across providers, Kurrier gives you a complete, modern, extensible platform.
Why Kurrier?
Kurrier is built as a next-generation alternative to traditional webmail and PIM suites — minimal, extensible, and designed for modern infrastructure:

⭐ Unified web interface
A clean, consistent UI for email, events, and address books across multiple identities and domains.
