The short version

  • Only Stoplight 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.; Stoplight the free plan allows one project and one user
  • They diverge on capability: Salt Edge covers Account information, Stoplight covers API Design.
  • 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.

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

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.

Stoplight: How much does Stoplight cost?

Stoplight starts with a free plan (1 project, 1 user), then Basic at $56/month per user (or $44/year), Startup at $147/month per user (or $113/year), Pro Team at $453/month per user (or $362/year), and Enterprise at custom pricing.

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.

Stoplight: How many included users are in each Stoplight plan?

Basic includes 3 users, Startup includes 8 users, and Pro Team includes 15 users. Additional users beyond the included count cost $14/month for Basic and Startup, or $27/month for Pro Team.

Salt Edge: Does it do payments as well as data?

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

Stoplight: Does Stoplight offer a free trial?

Yes, all paid Stoplight plans include a 14-day free trial. The free plan has no trial period as it is always available.

Salt Edge: What does it cost?

Not published. Pricing is usage-based and quoted, though the sandbox is free.
