The short version

  • Only Bruno has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bruno native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month; 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: Bruno covers API Testing, Ozone API covers Multi-standard support.
  • 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.

Bruno

  • Native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month
  • OpenAPI syncs are capped at 5 a month on the free tier
  • SSO, SCIM and user management require Ultimate at $11 per user per month
  • Private workspaces are a paid feature
  • Advertised prices are annual rates

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.

Pro ($6/month) includes native Git integration and unlimited workspaces. Ultimate ($11/month) adds SSO/SCIM support, audit logs, 24-hour support (vs. 48-hour), and an account manager. Ultimate supports unlimited OpenAPI syncs while Pro is limited to 5 per month.

It provides the standards-compliant API surface and adapters, but connecting your core is an integration project you scope separately.

The vendor claims Ultimate saves teams more than 70% versus Postman, though this comparison is promotional rather than a specific cost metric.
