The short version

  • Only Stainless has a free tier, so it costs nothing to try first.
  • Each has a real cost: Skaleet the installed base is in the tens rather than the hundreds, so the pool of consultants and systems integrators who know the platform is small and expensive.; Stainless starter and Pro plan prices are not published and require contacting the company.
  • They diverge on capability: Skaleet covers Cloud-native core, Stainless covers SDK generation.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Skaleet

  • The installed base is in the tens rather than the hundreds, so the pool of consultants and systems integrators who know the platform is small and expensive.
  • Speed references are mostly greenfield launches inside large groups, which is an easier problem than migrating an existing book off a legacy core.
  • It is European-centric, with payment rails and regulatory work concentrated on SEPA and EU requirements rather than global coverage.
  • As a smaller vendor carrying a bank core, it attracts hard concentration and viability questions in procurement that larger competitors do not face.
  • Pricing is unpublished and scaled by accounts and transactions, so a bank whose volumes grow faster than forecast faces cost escalation it did not model.

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.
