Command & Control
Without Compromise
ODIN is a free, open-source Command and Control Information System. Built for tactical mapping, situational awareness, and distributed coordination — with or without an internet connection.
Built for the Field
Everything you need for tactical planning and coordination, designed to work in challenging environments.
MIL-STD-2525C Symbology
Full support for military standard symbols. Drag, drop, and position tactical graphics with intuitive controls.
Offline-First
Self-host your map tiles and search services. ODIN works reliably without an internet connection.
Real-Time Collaboration
Built on the Matrix protocol for distributed, federated coordination across teams and organisations — with no central authority.
End-to-End Encrypted
All collaboration data encrypted by default using Megolm/Olm — the same proven crypto stack used by Signal. Not even the server can read your data.
Flexible Data Sources
Import WMTS, WMS, and GeoJSON layers. Export your work in standard formats for interoperability.
Productive Editing
Copy/paste, undo/redo, and tags for organizing layers. Link features to external URLs to extend your data without complexity.
Cross-Platform
Available for Windows, macOS, and Linux. Use it on the hardware you already have.
End-to-End Encryption
ODIN now encrypts all collaboration data by default. Your operational plans, tactical graphics, and situational data are protected with military-grade cryptography — from the moment they leave your device until they reach your team members.
Encryption keys never leave your devices. Not the server operator, not the network provider, not even Syncpoint can read your data.
Megolm/Olm — the same audited crypto stack used by Signal, Element, and adopted by NATO, the German Bundeswehr, and the French government.
When new members join, encryption keys are securely shared via encrypted channels. Full access to project history without compromising security.
SAS emoji comparison to verify device identity and prevent man-in-the-middle attacks. Trust is established between devices, not accounts.
