Deploy Radicale in one click installation.
Lightweight self-hosted CalDAV and CardDAV server for syncing calendars and contacts across all your devices.
What you can build with Radicale
Radicale is a small, simple, hassle-free CalDAV (calendar) and CardDAV (contact) server written in Python. It speaks the standard protocols that every modern operating system supports natively — iOS, macOS, Android, Thunderbird, Outlook, GNOME, KDE — so calendars and contacts sync to your devices without installing custom apps or browser extensions.
Self-hosting Radicale on your VPS keeps every event, address, and shared calendar on infrastructure you control rather than handed to a calendar SaaS. The server stores collections as plain files on disk, requires no database, and runs comfortably alongside other apps thanks to its tiny Python footprint.
Key features of Radicale
Standard CalDAV and CardDAV
Native sync with iOS, macOS, Android, Thunderbird, Outlook, GNOME, and KDE without third-party clients — every modern OS supports the protocols out of the box.
File-based storage
Calendars and contacts live as plain iCalendar and vCard files on disk — easy to back up, version-control, or migrate without database dumps.
Multi-user with sharing
Each authenticated user gets their own collections, with optional sharing rules for shared family or team calendars.
Tiny resource footprint
Pure-Python server with no database starts in seconds and uses tens of megabytes of memory — perfect for the smallest VPS plans.
Web admin interface
Built-in browser UI lets users browse collections, copy CalDAV/CardDAV URLs for client setup, and verify everything is working.
Reverse-proxy friendly
Designed to sit behind nginx, Apache, or Traefik with HTTPS termination upstream so deployment is simple and secure.

Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
