Where each one falls short

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

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.

Treblle

  • No free tier is offered; the entry-level Core plan starts at $233/month billed yearly.
  • Growth and Enterprise pricing is custom and not published, requiring a sales conversation to budget.
  • Core plan is limited to 1 workspace and only 30 days of data retention.
  • SSO and on-prem/BYO cloud deployment are reserved for the top Enterprise tier.
