Questions, answered
Everything you need to know about what FreeSDN is, what it supports, and how it keeps your infrastructure safe.
Frequently asked questions
Is FreeSDN really free?
Yes. FreeSDN is open source under AGPL-3.0 with no per-device fees, no seat licensing, and no cloud subscription. You self-host it and own your data. Every edition (Lite, Pro, and Max) is free.
What does FreeSDN actually manage?
FreeSDN unifies networking (switches, access points, WiFi, VLANs, PoE), firewalls and gateways, IP cameras and NVRs, VoIP/PBX, access control, compute (Proxmox), and storage (TrueNAS): 10 modules across 12 vendor adapters, under one dashboard and one API.
Which vendors and devices are supported?
12 vendor adapters today: TP-Link Omada, Ubiquiti UniFi, MikroTik, OpenWrt, OPNsense, pfSense, Hikvision, ONVIF, FreePBX, Grandstream, Proxmox, and TrueNAS. A typed plugin SDK lets you add more.
How does FreeSDN keep my devices safe from accidental changes?
Every device write rides a staged-change pipeline: changes are staged, then applied behind a dual gate (read-only flag plus an explicit force), with an atomic claim, full audit record, and saga-style rollback. Nothing touches device config without double confirmation.
Is it secure and multi-tenant?
Yes. FreeSDN uses application-layer, fail-closed tenant isolation (organization → site → device) with role-based access control (5 assignable roles) and per-user site grants. Credentials are encrypted at rest with Fernet (AES-128-CBC + HMAC-SHA256). See the Security & Trust page for the honest posture, including what is and isn't claimed.
Is FreeSDN production-ready?
FreeSDN is a pre-production / testing release intended for evaluation, testing, and homelab use today. It is not yet recommended for production or business-critical deployments; production readiness will be announced in a future release.
Can I extend it or build integrations?
Yes. FreeSDN ships a typed plugin SDK with a sandboxed, permission-declared runtime and a signed marketplace, plus Fabric, a universal app-interconnect that wires events to actions across apps. There's also a multi-provider AI assistant with a permission-gated tool registry.
Does it phone home or require the cloud?
No. FreeSDN is fully self-hosted and air-gappable. There is no telemetry requirement and no cloud dependency. The public demo even runs entirely in your browser with zero backend calls.
