Instantly audit & slash your Microsoft licensing bills.
Upload an RVTools export or run our lightweight scanner. WinSQLTool calculates every compliant Windows Server and SQL Server licensing path and surfaces the cheapest one — in minutes, not weeks.
How It Works
From raw inventory to optimized licensing plan in three steps.
Upload or Scan
Upload an RVTools .xlsx/.csv export directly from your vSphere environment. Our single-file scanner, winsqlscan.exe, ships with the pilot program — no agents, no installs either way.
Engine Calculates
Our backend applies Microsoft's exact core-licensing minimums — Datacenter vs. Standard, physical host vs. per-VM, SQL Enterprise cluster-wide vs. per-VM — and finds every legal savings path.

Full details, sample payload, and our data-handling commitments: Security & Privacy
Built for infrastructure teams
No sales calls. No consultants. Just upload your data and get answers.
Inspect before you upload
The scanner runs entirely on-premise and writes a plain JSON file you can open in Notepad. Nothing is transmitted until you choose to upload — and the payload contains no credentials, IPs, or PII.
Windows Server Datacenter vs. Standard
The engine models both paths: blanket Datacenter licensing on physical hosts vs. per-VM Standard licensing — and shows exactly where each wins.
SQL Server core-license optimizer
Compares per-VM Enterprise core licensing against whole-host licensing for your clusters. Standard Edition enforces the 4-core minimum. All math is shown.
RVTools import
Already have an RVTools export? Drop the .xlsx or .csv on the dashboard and we parse vInfo, vCPU, and vHost tabs automatically.
Auditor-ready output
Every report shows the applied Microsoft licensing rules, billable-core math, and per-scenario costs — ready to walk your LAR through line by line.
Results in minutes
Environments up to 10,000 servers process in a single upload. Most complete in under a minute.

Audits start at $500/year — and every additional year is half price. A single harvested Windows Server Standard license typically covers the fee.
