Every feature works on one machine for free, forever. Pro is only for organizations that need a central control plane across multiple machines.
All features included — nothing is paywalled for single-machine use.
Everything in Free, plus multi-machine orchestration.
14-day free trial when available. Powered by Stripe.
Free is genuinely free. We don't cripple the CLI to upsell you. Pro only adds fleet (multi-machine) capabilities.

No. Every feature works on one machine with zero restrictions — monitoring, scheduling, reports, fixes, compliance mapping, all of it. There's no trial period, no feature gates, no "upgrade to unlock." Free means free.
Pro is exclusively for fleet management — when your organization needs a central control plane to monitor and manage multiple Windows machines. If you only have one machine, you never need Pro.
No. Every audit module is deterministic .NET code hitting real Windows APIs — zero network calls. The optional AI advisor talks to a local Ollama instance. No OpenAI, Anthropic, or any third-party LLM is ever called. On Pro, only machines you explicitly connect to the fleet dashboard push results — and you control redaction.
Pro scales by how many machines report to the fleet dashboard: 25 nodes = $29/mo, 100 nodes = $79/mo, unlimited = contact us. You pick the tier that fits; no per-seat math.
Yes — pay annually and save 17%. The 25-node tier is $290/year (effectively $24.17/mo) and the 100-node tier is $790/year. Toggle the billing switch at the top of this page to see annual pricing.
Yes — 30-day, no-questions-asked refund on Pro. Cancel directly in Stripe (link in your purchase receipt) and we'll auto-refund the last charge.
Stripe Checkout is being wired up right now. If you click "Get Pro early access" before launch, you'll go straight to the waitlist and get a one-time invite when Pro opens.
