The short version

  • Only WSO2 API Manager has a free tier, so it costs nothing to try first.
  • Each has a real cost: Salt Edge coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.; WSO2 API Manager the free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • They diverge on capability: Salt Edge covers Account information, WSO2 API Manager covers API Gateway.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Salt Edge

  • Coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.
  • Pricing is not published and is usage-based, so two providers cannot be compared without running both sales processes, and cost grows with the connected user base rather than with revenue.
  • Support and engineering are distributed across Eastern Europe and Canada, and buyers in other time zones report slower turnaround on connection-specific breakages than they get from a domestic provider.
  • PSD2 consent rules require customers to reauthenticate periodically, and Salt Edge cannot change that, so any product depending on continuous data must design for consent expiry and the drop-off it causes.
  • United States coverage is weaker than Plaid or Mastercard Open Banking, so a company with meaningful US volume ends up running two aggregators and normalising between them.

WSO2 API Manager

  • The free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • A commercial production licence is not part of the free download and comes only with a subscription
  • No subscription price is published; Basic Support and Enterprise Support both require contacting sales for a quote
  • 24x7x365 coverage requires Enterprise Support; the general query SLA is one business day
  • A Customer Success Manager is a paid optional add on covering business hours only
  • Consulting services and WSO2 Private Cloud hosting are quoted separately

Answered from the vendors’ own pages

Salt Edge: Who owns Salt Edge?

It is independently owned, unlike Tink (Visa), Finicity (Mastercard) or Yodlee (Envestnet), which matters if your use case competes with the owner.

WSO2 API Manager: How is WSO2 API Manager priced?

WSO2 API Manager pricing is not published on their website. As an enterprise API management platform, pricing is custom-quoted based on deployment model and organizational requirements.

Salt Edge: Is all coverage direct bank API?

No. Inside PSD2 markets connections use regulated APIs; elsewhere coverage relies on direct connections whose reliability depends on the bank not changing its systems. Ask for a per-institution answer.

WSO2 API Manager supports multiple deployment options including on-premises and cloud, but pricing structures for different deployment models are not publicly disclosed.

Yes, payment initiation is supported in European markets where PSD2 applies.

WSO2 API Manager: What deployment flexibility does WSO2 API Manager provide?
