VDX turns any amd64 server into a self-hosted VDI cluster node. Boot one ISO, get browser desktops, built-in video calling, and horizontal scale — for 1/10th the cost of Citrix.
Linux desktops only. Intentionally. No per-device CALs, no Microsoft licensing maze.
One Go binary. One ISO. Every session is a KVM-accelerated Linux VM running your squashfs image.
No modules, no per-feature licensing, no hidden costs.
Full Linux desktop in any browser tab via Guacamole. Webcam, microphone, clipboard, audio — zero plugin, zero client install. Works on iPad.
WebRTC audio/video calling between portal users. Browser-to-browser, no Zoom subscription, no external SFU. Works on LAN without internet. PSTN gateway via Asterisk (Enterprise).
Add nodes to the cluster; sessions auto-place on the least-loaded node. mDNS discovery, gossip replication — no central coordinator.
uftp multicast distributes squashfs OS updates to every cluster node in the time it takes to send to one. Flat bandwidth cost regardless of node count.
OIDC client for Okta, Azure AD, and Google Workspace. AD group → VDX role mapping. Session-to-user binding with display name injection via cloud-init.
Sessions backed by ZFS zvols with lz4 compression and optional dedup. Snapshots, live resize, TRIM passthrough. Full root union or /home-only — your call.
Every node gets two browser-trusted HTTPS addresses — one public (acme.vdxcloud.com, anywhere in the world) and one internal (acme.internal.vdxcloud.com, resolves to your LAN IP). Let's Encrypt cert issued automatically. No internal CA, no warnings, no port forwarding.
QEMU live migration between cluster nodes. Move running sessions between hosts for maintenance or load balancing — session continues without disconnect.
WireGuard config file in → guest VMs get a second interface on your corporate LAN. SMB/CIFS, internal DNS, file servers — all accessible from the browser desktop.
VDX vs the incumbents — on your hardware

Citrix/Horizon pricing estimated for 25-seat on-prem deployment, Jan 2026 list price. Azure VDI includes AVD + M365 Business Basic.
Every registered VDX node gets a permanent public subdomain and a LAN-local subdomain — both backed by a real Let's Encrypt certificate. No self-signed warnings, no internal CA to distribute, no firewall exceptions.
acmecorp.vdxcloud.comPublic — works anywhere via WireGuard tunnel. Hotel NAT, CGNAT, ships, aircraft.
acmecorp.internal.vdxcloud.comInternal — public DNS resolves to your LAN IP (e.g. 10.20.5.50). Browser connects directly. Full wire speed. No tunnel overhead.
Let's Encrypt issues certs via DNS-01 challenge — your server never needs to be internet-reachable. Same technique Tailscale and Teleport use for internal nodes.
All tiers include browser desktop, audio, webcam, and built-in peer calling. Linux-only — no Windows CAL maze.
