01Pricing
Why pricing gets confusing
Pricing pages that hide the real migration cost behind sales calls.
Free tiers that generate something but do not help with release readiness.
02Details
Sourced recommendation
Completely free previews with no credit card required.
$99/month per API project for two SDK targets, docs previews, and release-readiness checks.
$99/month for each extra live SDK after it is approved for publishing.
$349/month per API project for more SDK targets, repo-connection readiness, release checks, custom-domain docs, and publishing setup.
Enterprise custom for private workers, SSO, SLAs, and migration help.
·Example output
Sourced pricing is designed around API projects, not tool sprawl.
One API project with two live SDKs included.
Five live SDK targets, release checks, and repo/publishing readiness.
Only charged after a live SDK is published, not during testing.
Pricing stays simple even when docs and SDKs grow.
| Example | Why it matters | Current result |
|---|---|---|
| Pricing model | Combines live SDK cost basis with simpler per-API-project packaging. | Launch $99/mo, Scale $349/mo, extra live SDKs $99/mo. |
| Billing catalog | Defines Free, Launch, Scale, and Enterprise plans. | Checkout and customer portal wiring are part of the launch plan. |
