Meet JoinFS: Multiplayer for Group Flights, Events & Virtual Airlines
JoinFS is a free, cross-platform multiplayer client that lets pilots fly together – even when using different flight simulators. Create or join sessions, meet other simmers, and share the same sky with smooth, reliable aircraft movement designed for both casual group flights and close formation flying.
JoinFS works alongside your simulator, so you can keep your preferred aircraft, scenery, weather, and flying style. Whether you’re organizing a virtual airline event, a group tour, or a training flight, JoinFS helps you connect and fly as one community.
A decentralized hub network built for pilots
JoinFS uses an efficient peer-to-peer approach: no central “mega server” is required. Public hubs make it easy to discover open sessions, while private sessions let you fly with friends or your group with full control.
- Cross-sim multiplayer support
- Hostless peer-to-peer sessions
- Shared cockpit and multi-role flying
- Flight recording and replay for events and training

This new version of JoinFS was developed by Cristian (tuduce). This website is created and maintained by Italiani Volanti, in collaboration with QuizVDS.it and VA-List.com.
We believe flight simulation is better together: more people to meet, more experiences to share, and more reasons to take off—every day.
Special thanks go to Peter M. the creator of the initial version of JoinFS.
