Comparisons

How free NexCMP compares for CloudStack billing

NexCMP is a free, self-hosted billing panel and cloud control panel for Apache CloudStack and Proxmox VE in one build. Here is how that compares to the products that usually cover just one of those jobs.

Methodology: Public vendor pricing and feature pages, accessed 2026-09-27–28. Only entries confirmed against an official source are shown. Prices are as published by each vendor and may exclude tax or VAT. Where a vendor does not publish a price, this page says "Contact sales" or "Not published" instead of guessing.

Where NexCMP fits

Most billing panels stop at the invoice and most VPS/cloud panels stop at provisioning. NexCMP covers orchestration and billing together for Apache CloudStack and Proxmox VE, in one self-hosted build.

Diagram: three product categories most vendors cover separately, and NexCMP spanning all of them.

Architecture: what each product runs on

NexCMP is a Rust binary with an embedded database. The PHP billing panels below document a PHP runtime, a database and more. This compares architecture only, not features or speed.

  • NexCMP

    Built with
    Rust server (axum, tokio), Vue 3 portal and admin, Go node agent
    What you install and run
    One binary with the web interface embedded and an embedded SQLite database; nginx in front, set up by the installer. No PHP, no ionCube Loader, no separate database server.

  • WHMCS

    Built with
    PHP
    What you install and run
    PHP 8.2, 8.3 or 8.4 with the ionCube Loader (15 or newer); MySQL (MariaDB may also work); a cron job; validated on the Apache web server.

  • HostBill

    Built with
    PHP
    What you install and run
    PHP 8.1 or newer (8.3 recommended) with ionCube Loaders 14.x or later; MySQL 5.7 or later with strict mode disabled.

  • Blesta

    Built with
    PHP (its own minPHP framework)
    What you install and run
    PHP 8.2, 8.3 or 8.4 (8.3 recommended) with ionCube Loaders v15+; MySQL 5.7.7+ or MariaDB 10.2.2+; a cron job every minute.

Vendor requirements are quoted from each vendor's own documentation, read on 2026-10-30, and change between versions; check the vendor. WHMCS, HostBill and Blesta also have large module ecosystems and cover general web-hosting billing that NexCMP does not.

How NexCMP is built

The CloudStack ecosystem

NexCMP connects to Apache CloudStack — an open-source project with its own ecosystem of specialist partners and add-ons, shown here for context rather than as a head-to-head comparison.

ShapeBlue

An Apache CloudStack integrator and partner, not a billing or CMP vendor. Its services span 24/7 infrastructure support (quote-only SLA subscription), IaaS consulting and design, official CloudStack training and certification ($100 per exam), custom software engineering for the CloudStack core, and a VMware-to-CloudStack migration tool (ShapeBlue Migrate) available to its customers.

StackBill / StackOrbit — StackWatch, StackVault & StackObject

StackBill (now StackOrbit) is compared directly above. Its StackWatch (monitoring), StackVault (backup/DR) and StackObject (Ceph-based S3 object storage, multi-tenant/reseller-ready) are paid add-ons sold alongside the StackBill CMP, not standalone products, and none publishes an independent price.

Where others are stronger

An honest comparison cuts both ways — here is where the products above are ahead of NexCMP today.

  • Module and integration ecosystems: WHMCS lists 500+ third-party integrations, and HostBill lists native modules for a wide range of platforms (CloudStack, OpenStack, Proxmox, Virtualizor, VMware vCloud Director, SolusVM 2, Virtuozzo).
  • Multiple hypervisors out of the box: Virtualizor manages KVM, OpenVZ, Xen PV/HVM, XenServer, LXC and Virtuozzo from one panel, and Xen Orchestra covers XCP-ng and XenServer — NexCMP sells VMs from Apache CloudStack and, since 1.3.0, Proxmox VE; OpenStack is in development, and there is no connector for Xen, VMware or OpenVZ.
  • Dedicated CloudStack partner services: ShapeBlue offers 24/7 SLA support, consulting, training/certification and custom engineering for CloudStack — a specialist layer NexCMP does not offer.
  • Maturity and high availability: established billing panels have years of production use across many providers; NexCMP is newer, and its control plane is a single-node process pair with no high-availability mode.
See the plan to address these gaps: November 2026–December 2027
