The short version

  • Each has a real cost: Payload CMS payload is a Next.js fullstack framework and installs into a Next.js app, so it is not framework-agnostic; Stainless starter and Pro plan prices are not published and require contacting the company.
  • They diverge on capability: Payload CMS covers REST API, Stainless covers SDK generation.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Payload CMS

  • Payload is a Next.js fullstack framework and installs into a Next.js app, so it is not framework-agnostic
  • Database support is limited to MongoDB and Postgres
  • SSO is an Enterprise-only feature
  • Publishing workflows, the visual editor, static A/B testing and AI auto-embedding are listed as Enterprise features
  • Enterprise is sold through a Schedule a Demo form with no published price
  • Free support is through a Discord community rather than a vendor support channel

Stainless

  • Starter and Pro plan prices are not published and require contacting the company.
  • The free plan caps APIs at 25 endpoints, which excludes larger production APIs.
  • Overage charges apply per SDK/endpoint/month once limits are exceeded, which can make costs unpredictable at scale.
