V1
Free guided checks, local progress, hints, and solution reveal tracking.
Account placeholder
Free labs first. Accounts and paid packs later.
V1 is intentionally anonymous and backend-free. The first sellable product should be premium lab packs: advanced checks, downloadable manifests, full solutions, and architecture review worksheets.
V2
Premium lab packs with downloadable kits, advanced scenarios, and review worksheets.
V3
Hosted labs only after auth, abuse controls, sandbox lifecycle, and cost limits are designed.
Premium labs later
Advanced solutions, downloadable kits, and review worksheets will become the first paid product.
