Nordic open banking payments and data, now with UK coverage through Ordo

The short version
- Only curl has a free tier, so it costs nothing to try first.
- Each has a real cost: curl open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply; Neonomics coverage outside the Nordics and the UK is comparatively shallow, so a pan European merchant will find gaps and inconsistent bank behaviour in southern and eastern markets.
- They diverge on capability: curl covers HTTP/HTTPS, Neonomics covers Payment initiation.
- 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.
curl
- Open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply
- Commercial support costs hidden: site references 'commercial support available' but pricing is not detailed or accessible from homepage
- No SaaS model: curl is a command-line tool and library; costs are limited to optional commercial support contracts (pricing unknown)
- Self-support burden: free software means customers rely on community forums or undisclosed commercial support pricing
Neonomics
- Coverage outside the Nordics and the UK is comparatively shallow, so a pan European merchant will find gaps and inconsistent bank behaviour in southern and eastern markets.
- It is a small company relative to Tink and TrueLayer, so supplier viability and the depth of engineering support behind bank API changes are genuine procurement questions.
- Payment initiation only means the merchant handles settlement, reconciliation and refunds, and there is no chargeback framework to fall back on.
- Integrating a recently acquired UK business means two regulatory entities and, for a period, two technology stacks, so cross market feature parity is a promise rather than an existing state.
- Conversion is governed by each bank's own authentication experience, and Nordic BankID flows behave differently from UK app redirects, so a single UX cannot be assumed across the footprint.
