The short version

  • Only Stoplight has a free tier, so it costs nothing to try first.
  • Each has a real cost: Stoplight the free plan allows one project and one user; Zimpler pricing is not published and is set by industry and risk profile, so smaller merchants cannot benchmark a quote and often discover they are paying well above a general-purpose provider.
  • They diverge on capability: Stoplight covers API Design, Zimpler covers Bank payments.
  • 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.

Stoplight

  • The free plan allows one project and one user
  • Private projects, multi branch support and custom domains start at the Startup plan, $113 a month billed annually
  • SSO and shared style guides are Pro Team only, at $362 a month billed annually
  • Seats beyond each plan's allowance are $11 to $27 each per month depending on tier and billing period

Zimpler

  • Pricing is not published and is set by industry and risk profile, so smaller merchants cannot benchmark a quote and often discover they are paying well above a general-purpose provider.
  • As a payment facilitator carrying merchant risk, it declines or offboards merchants on risk grounds, which makes it a dependency you cannot assume will persist.
  • Its strength is concentrated in the Nordics, and coverage in southern and eastern Europe is thinner than pan-European account-to-account specialists.
  • Revenue concentration in iGaming ties the provider to a sector under constant regulatory change, so licence changes in one market affect the supplier as well as the merchant.
  • Bank transfers have no chargeback protection, so disputes are handled commercially and consumers used to card protections may resist the payment method.
