No catch, no upsell, no lock-in
There is no commercial edition hiding behind these profiles. The promises below hold for Lite, Pro, and Max alike. They're properties of the project, not a plan you pay for.
AGPL-3.0 open source
The entire platform is free and open under AGPL-3.0. Inspect it, fork it, extend it, forever.
No seat or per-device licensing
Manage one device or ten thousand. There are no seats to count and no per-device fees in FreeSDN's licensing.
No cloud lock-in: air-gappable
FreeSDN is fully self-hosted with no telemetry requirement and no cloud dependency. Run it offline.
Your data stays yours
Configs, credentials, and telemetry live on your infrastructure. By default nothing leaves your network; opt-in cloud integrations are yours to control.
Editions are deployment footprints, not feature gates
Every edition ships the full set of 10 core modules and all 12 vendor adapters. Nothing is locked behind a higher tier. What changes between Lite, Pro, and Max is the deployment footprint: how many moving parts you run, and whether you add background workers, multi-tenant RBAC, and high-availability infrastructure as your estate grows.
Start on a single node with Lite, then grow into Pro and Max without re-platforming.
Same modules, same 12 adapters, same typed API across every profile.
The difference is footprint and HA: workers, multi-tenancy, and scale-out, not paywalled features.
Pick a profile and deploy
Start with Lite on a single node, or plan a Pro/Max deployment, all free, all self-hosted.
