Switching from Keygen to Keymaster is mostly a matter of following the same three steps every OneTimeSuite app uses — buy once, deploy or install, bring your workflow over.
Step 1: Buy once on Whop
One-time $49 for the packaged, ready-to-run version with a Windows installer and priority support.
Step 2: Deploy and integrate
docker compose up on a $5 VPS, then drop the 20-line verification snippet into your app with your public key embedded at build time.
Step 3: Issue keys, ship builds
Issue or bulk-issue licenses from the dashboard, wire the webhook into Stripe or Whop, and let customers download through expiring signed URLs.
What to expect during the switch
Keymaster covers the same core workflow as Keygen, so most people are productive within the first session — see the full feature list and FAQ on the product page before you commit.
Why make the switch at all
Keygen runs from $99/mo, forever. Keymaster is $49, once. Against Keygen's $99/mo entry tier, Keymaster pays for itself in 15 days. Against Gumroad's 10% cut, it pays for itself on your first ~$500 of sales.
Try Keymaster — $49, once
