The VPS hosting platform
built under your brand.
Multi-tenant, white-label SaaS that lets hosting companies sell and manage VPS services. Proxmox automation, billing, and client portals — shipped, ready.
BUILT ON BATTLE-TESTED OPEN SOURCE
Django Proxmox VE React PostgreSQL Redis GraphQL
Everything you need to run a hosting business
Stop building infrastructure from scratch. Start selling servers.
Multi-tenant by design
Fully isolated environments per hosting company — data, branding, billing, and pricing all separate.
White-label branding
Custom domains, logos, colors, themes, TOS. Your clients see your brand, not ours.
Proxmox automation
Native Proxmox VE API integration for VM provisioning, cloud-init, snapshots, backups, bandwidth.
Billing built-in
Invoices, account balance, gift cards, auto-renewal, tax handling. No separate billing system needed.
Security hardened
2FA, brute-force protection, rate limiting, HMAC webhooks, encrypted credentials, CSP headers.
VNC console
Full browser-based VNC console with paste support. Your clients manage servers without leaving the portal.
Client self-service
Complete client portal: VPS management, billing, profile, 6-step order wizard, OAuth login.
GraphQL API
65+ operations, fully typed. Integrate with your existing stack or build custom automations on top.
