01Plans
What both plans give you
Docs previews with custom-domain launch plans.
Editor and collaboration features.
Public and private docs.
02Pricing
Where the pricing models differ
GitBook scales by site and seats — common for knowledge-base teams.
Sourced scales by API project — fits when API docs are the product, not a section.
If you publish docs for many products, GitBook may be cheaper at small scale.
If you publish docs for one or two APIs, Sourced is simpler.
03Teams
What changes for SDK-shipping teams
GitBook does not generate SDKs.
If you also need TypeScript and Python SDKs, you're buying two tools with GitBook; one with Sourced.
Migration reports, llms.txt, and compatibility checks are Sourced-only.
·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.
