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; Ozone API it provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • They diverge on capability: GraphQL Playground covers Query building, Ozone API covers Multi-standard support.

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

Ozone API

  • It provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • Value is driven by regulatory obligation, so an institution not under a mandate struggles to build a business case for the spend.
  • It is a small UK vendor selling to large regulated institutions, which raises procurement and vendor viability questions during bank due diligence.
  • Premium API monetisation is a genuine capability but few banks have found real demand, so revenue projections used to justify the purchase often do not materialise.
  • Standards evolve continuously and each revision means a change programme in your own systems, even where Ozone absorbs the specification work at the API edge.
