01Details

Questions to ask in a Stainless sales call

01

What is the price per live SDK at our publishing cadence?

02

What changes if we add a third or fourth language?

03

How does pricing change if we host docs through Stainless's docs platform?

04

What's the annual commitment vs monthly?

02Details

What changes if Sourced replaces Stainless

01

Per-API-project pricing — easier to budget against.

02

TypeScript and Python covered today; other languages on the roadmap.

03

Migration report runs before any publish; old Stainless package can stay live during cutover.

03Switching path

If the pricing math favors Sourced, here's the four-step migration path

Reversible — nothing reaches a customer until you approve the report.

  1. 01

    Upload OpenAPI + stainless.yml

    Sourced reads both, preserves package names and auth env vars, and inventories the resources your current SDK exposes.

  2. 02

    Read the compatibility report

    Sourced diffs the generated TypeScript and Python SDK against your current Stainless package. Zero missing methods is the target.

  3. 03

    Preview docs and SDK output

    Hosted preview at a private URL. Downloadable SDK packages. Customers see nothing.

  4. 04

    Publish on your timeline

    Prepare repo-sync, registry readiness, and docs cutover checks; external writes stay behind approval.
