Generation config, overlays, and workflow files need a portability check.
Provider migration
Migrate from Speakeasy to Sourced
Speakeasy is OpenAPI-native and powerful, so the buyer question is not raw generation. It is whether your release workflow, SDK surface, and docs output remain stable when you switch. On this page: what to scan in your Speakeasy setup, the migration checks Sourced runs, and a preview of the generated SDK and docs you would get.

What to check
SDK runtime behavior should be compared language-by-language.
Publishing setup for npm, PyPI, Maven, or Go needs a dry run.
CLI, Terraform, and MCP targets may need separate plans.

Migration checklist
Inventory every overlay file (.speakeasy/overlays/*) — Sourced inlines spec edits or runs them as a pre-build, not via runtime overlays.
List every generated SDK target (typescript, python, go, java) and run the compatibility report per language before publishing.
Capture the .speakeasy/workflow.yaml CI integration so the same publish trigger maps to Sourced's release flow.
For each MCP / Terraform target, decide whether to retire (Sourced roadmap), keep on Speakeasy, or move to a single-target generator alongside.
Dry-run the package publish to each registry (npm/PyPI/Maven) against a scratch package before swapping the real ones.
03Details
Why Sourced fits
Sourced packages docs + SDKs as one workflow; Speakeasy users typically bolt docs on separately.
Compatibility report ships breaking-change detection as a written artifact, not just a CLI exit code.
Pricing scales per API project, not per language target — no $600/mo/lang line item.
Currently TypeScript + Python first-class; Go/Java/Ruby on the roadmap (honest trade-off vs Speakeasy's breadth).
