Stop defending spreadsheets
at change board.

You author the design. VCF Designer runs 122 validation checks, sizes every domain, and assembles the HLD — so you arrive at change board with evidence, not estimates.

Audience

Built for VCF Practitioners

Independent consultants

Import your Planning Workbook or RVTools export. Every constraint validated, topology visualised, HLD assembled. Arrive at delivery with a defensible design, not a best-effort spreadsheet.

Consulting firms

Consistent, traceable design quality across every team and engagement. Every architect working to the same 122-rule standard — so designs survive change board, not just peer review.

Internal platform engineers

Design with the same rigour as external specialists. Every rule traceable to published VMware by Broadcom by Broadcom specifications — a complete audit trail from design decision to documented maximum.

Design workflow

Where the Planning Workbook Stops

Design errors caught here cost nothing. The same errors surfaced at change board cost credibility, rework, and project time.

  1. 01
    Manual resource calculations. CPU, memory, and storage totals computed by hand. Errors propagate silently across sheets.
  2. 02
    No live validation. Configuration maximums checked after the fact, or not at all.
  3. 03
    Document generation is separate. The workbook captures data. The HLD is authored in Word. Keeping the two in sync is manual effort.
  4. 04
    No fleet-scale design. Multi-instance deployments require duplicating and cross-referencing multiple workbooks.
  5. 05
    No version history. Changes between design iterations tracked by filename or memory.

Common questions

FAQ

A browser-based design and validation tool for VMware Cloud Foundation by Broadcom. Import a Planning Workbook, validate against 122 rules, and export a client-ready HLD. Nothing leaves your machine.

Nowhere. VCF Designer is browser-only: your designs live in your browser's local storage on your machine. There is no backend that receives, stores or processes your environment data — nothing about your infrastructure ever reaches our servers. The honest one-liner for your security team: the data is stored wherever you put the file, and nowhere else.

There is usually nothing to review. No data leaves the browser, so there is no data-processing agreement to negotiate, no vendor infrastructure to assess and nothing to provision. The optional environment collector is a read-only PowerCLI script you run yourself — a few hundred lines of readable PowerShell, not a binary — which writes a JSON file locally that you drag into the app. Credentials are held in memory for the run only and never written to disk.

Yes. After the initial page load, no backend connection is required.

VCF 9.0 is fully supported today. VCF 9.1 support is in active development and will land alongside 9.0 — nothing you build on 9.0 goes away. All validation rules are version-specific.

Yes. Planning Workbooks import directly, including multi-file import for fleet instances. RVTools is also supported for VM inventory.

Word (.docx), Excel, JSON, Draw.io, and .vcfdesign native format. All exports carry your configured company branding.

Yes. VCF Designer includes a licensing estimate calculator that factors in core counts, base VCF subscription costs, and add-on features such as VMware Firewall, vSAN capacity, Tanzu, and disaster recovery. It gives consultants and clients a realistic view of what the full architecture — including optional feature sets — could cost to license.

All resource requirements are sourced from official VCF 9.0 specifications. Capacity validation includes HA headroom across all 8 appliance types.

Yes — stretched vSAN, Availability Zones, multi-rack networking (L2/L3), NSX Federation with Global Manager, and cross-site RTEP.

Yes. A step-by-step wizard captures project context, business requirements, and infrastructure settings — your design is pre-configured from the answers.

A panel of 10 senior VCF architects and certified specialists scored it 8.4/10 on production readiness. All 10 said they would use it.

Auto-saved to browser storage. Export as .vcfdesign or JSON to share. Version history keeps the last 5 snapshots with readable diffs.
