The short version

  • Only GraphQL Playground has a free tier, so it costs nothing to try first.
  • Each has a real cost: GraphQL Playground apollo's own documentation states GraphQL Playground is officially retired and no longer recommended, directing users to Apollo Sandbox instead; 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.
  • They diverge on capability: GraphQL Playground covers Query building, Salt Edge covers Account information.
  • Prices and features above were last checked on 31 August 2026.

  • A fintech that wants an aggregator not owned by a card network because its use case competes with card productsnot GraphQL Playground
  • An accounting or treasury product that needs bank feeds in markets the large aggregators do not servenot GraphQL Playground
  • A bank that must publish PSD2-compliant APIs and would rather buy the compliance layer than build itnot GraphQL Playground

Where each one falls short

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

GraphQL Playground

  • Apollo's own documentation states GraphQL Playground is officially retired and no longer recommended, directing users to Apollo Sandbox instead

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.

Answered from the vendors’ own pages

GraphQL Playground: Is GraphQL Playground free to use?

GraphQL Playground is a testing tool for Apollo Server and is free to use as part of the Apollo Server documentation. However, the broader Apollo GraphQL platform has various paid tiers available for production use.

Source
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.

GraphQL Playground: Is GraphQL Playground part of a paid product?

GraphQL Playground is a testing tool within the Apollo ecosystem. While Playground itself is free, Apollo offers paid tiers starting at $5 per million requests for the Developer tier, with Standard and Enterprise plans available at custom pricing.

Source
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.

GraphQL Playground: What is the cost structure for Apollo GraphQL's paid plans?

Apollo uses volume-based tiered pricing for requests: first 250M operations cost $5.00 per million plus $2.00 for performance add-on; next 750M operations are $4.25 per million plus $1.50 add-on; additional tiers scale down to $3.00 per million plus $0.50 add-on for operations over 5 billion.

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

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

Salt Edge: What does it cost?

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