Pay per active learner.

A distinct learner who launches at least one session within your 30-day billing period — counted once, no matter how many launches, sessions, or courses they touch. Note this is a different unit than SCORM Cloud's "registration", which is one learner on one course — there, a learner who takes three courses counts three times. Launches, xAPI statements, and storage are fair-use guardrails, never the thing you budget against.

Rustici literally published a post titled "SCORM Cloud Pricing Tiers: The Edge of the Cliff" — on registration-bucket plans, crossing a threshold means paying per-registration overage (up to $3.60 per registration on smaller plans) or jumping to a much bigger plan. We removed that. Once you pass your included learners, you simply pay per learner, and that per-learner rate drops across self-serve plans: $0.15 on Starter, $0.08 on Growth, and $0.05 on Scale. Enterprise overage terms are custom.

On any paid plan, nothing breaks — caps are soft. Your product keeps serving learners and the extra ones bill at your plan's overage rate. We alert you at 70%, 90%, and 100% of your allotment so there's no surprise. The Free plan is the only hard cap: the 26th distinct learner in a period is blocked with an upgrade prompt.

Two ways. Usage alerts at 70/90/100% keep you ahead of overage. And on Scale and Enterprise you can pre-buy a learner-credit balance that overage draws down — configure it to either alert-and-stop (a hard ceiling, no bill shock) or continue metered. Annual commitments are available on Scale and Enterprise for procurement-driven buyers.

Growth and up. The sub-tenant / child-workspace API lets a parent-scoped key mint and manage isolated workspaces programmatically, with rolled-up billing and per-child quotas — what you need to run a multi-tenant SaaS or an AI builder that provisions a workspace per customer. Scale and Enterprise add full white-label.

No — they're not metered. They exist as fair-use guardrails to prevent abuse, but you're billed on active learners only. This is deliberate: it's the unit your buyers already understand, and it means a learner who runs ten courses doesn't cost you ten times more.

Two differences. First, the unit: SCORM Cloud meters registrations (one learner on one course), sold in paid tiers with 10, 50, 100, 300, 4,000, 10,000, or 50,000 registrations from $40 to $5,000/mo and published overage from $3.60 down to $0.10. We meter active learners — one learner counted once per period, no matter how many courses — so multi-course learners don't multiply your bill. Second, SCORM Cloud charges a learner-course association when it is created, while relaunches of that existing association do not create another registration.

Yes — free forever, no credit card. 25 active learners (resettable monthly), 5 GB storage, the fully-featured API and GPT Actions. Output is watermarked and packages expire after 30 days, so it's built for development and testing, not production. When you ship, $49 takes the watermark off.
