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; Volt account-to-account payments carry no chargeback mechanism, so consumers lose scheme dispute protection and merchants lose a familiar framework for handling claims.
  • They diverge on capability: Stoplight covers API Design, Volt covers Pay by bank.
  • 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

Volt

  • Account-to-account payments carry no chargeback mechanism, so consumers lose scheme dispute protection and merchants lose a familiar framework for handling claims.
  • Refunds are outbound payments rather than reversals, which changes treasury handling and means a refund can fail for reasons a card refund never would.
  • Conversion is lower than a stored card because the shopper must complete a bank authentication journey, and drop-off varies significantly by bank.
  • Core pay by bank pricing is per transaction but refunds, payouts, virtual IBANs, Verify and fraud tooling are billed separately, so the real cost is a stack of line items.
  • Bank API availability and quality vary across markets, and an outage at a major bank removes a slice of your checkout with no fallback unless you keep cards live.
