Platform Migration
Unit Commander has been retired and rebuilt from the ground up as MilSim.io - a faster, more powerful platform for managing MilSim communities, units, applications, members, and operations.
Looking for Unit Commander Pro? You're in the right place. MilSim.io is the new home for Unit Commander communities.
Migration guide
Unit Commander served milsim communities for years before the platform was deprecated. MilSim.io C2 was built to replace it — same problem space (rosters, ranks, applications, operations) with a modern stack, a real API, and a public profile layer that doubles as a recruitment surface. If you used Unit Commander, the migration path is direct: your data model maps cleanly to C2.
What carried over
C2 covers the same surface UC did — rosters, ranks, applications, events, communications, attendance — and adds the discovery layer UC never had. Your public community profile on MilSim.io becomes your recruitment landing page, indexed by Google, accessible to recruiters without an account.
For former UC admins
The free tier covers community profiles and basic roster management. The Captain tier unlocks applications and attendance. Most units that ran UC at full capacity land on Captain. C2's pricing is per-community, not per-seat.
Unit Commander has officially moved to MilSim.io.
Rather than continuing to maintain two separate platforms, Unit Commander has been rebuilt into a newer, faster, and more capable system under the MilSim.io name. Existing Unit Commander communities can move to MilSim.io to keep managing members, applications, roles, recruitment, and day-to-day community operations.
MilSim.io gives the platform a stronger foundation for the future. It is designed around how modern MilSim communities actually work, with better performance, cleaner workflows, and room for features that were not practical in the original Unit Commander stack.
MilSim.io brings community management, recruiting, and operations workflows together in one modern platform.
