Nordigen (now part of GoCardless) pioneered free PSD2 account information services in Europe. But as the open banking landscape matures in 2026, developers and small teams are evaluating alternatives for good reasons: pricing changes after acquisition, rate limits on free tiers, and the question of whether you need an aggregator at all versus connecting directly to bank APIs.
This guide compares the main Nordigen alternatives for accessing European bank account data, with a focus on what matters to developers and small businesses: cost, certificate requirements, bank coverage, and self-hosting options.
Why Look Beyond Nordigen?
Nordigen was acquired by GoCardless in 2022, and since then the product has been integrated into the GoCardless platform. For developers who originally chose Nordigen for its free, developer-friendly API, several shifts have prompted a search for alternatives:
- Pricing uncertainty: The free tier has become more restrictive, and pricing for production use is less transparent than it was as an independent company.
- Aggregator dependency: Every request routes through Nordigen's infrastructure. If their service degrades, your application degrades.
- Data sovereignty: Some teams prefer to hold bank API connections directly rather than routing through a third party.
The Key Question: Aggregator or Direct API?
Before comparing specific alternatives, it's worth understanding the two architectural approaches:
Aggregators (Nordigen, TrueLayer, Tink, Salt Edge) provide a unified API that abstracts away individual bank APIs. You integrate once and get access to hundreds of banks. The trade-off is an additional layer between you and the bank, plus per-API-call costs.
Direct API / Self-hosted approaches let you connect to bank APIs yourself using PSD2 open banking standards. This eliminates the aggregator middleman and per-call fees but requires you to handle bank API differences, authentication flows, and — traditionally — an eIDAS QWAC certificate.
Nordigen Alternatives Compared
1. TrueLayer
TrueLayer is the most prominent Nordigen competitor in the UK and European markets. They offer a polished API with strong documentation and broad bank coverage.
- Coverage: 1,500+ banks across Europe
- Pricing: Free sandbox; production pricing is usage-based, starting around £0.10-0.30 per successful API call depending on endpoint
- Certificate required: No — TrueLayer handles PSD2 compliance
- Best for: Teams that want a premium managed API and can absorb per-call costs
2. Tink (Visa)
Tink was acquired by Visa in 2022 and offers account aggregation, payment initiation, and data enrichment. Their API is well-regarded for data quality and categorization features.
- Coverage: 6,000+ banks globally (including non-PSD2 markets)
- Pricing: Enterprise-focused; limited free tier
- Certificate required: No — Tink handles compliance
- Best for: Larger teams needing enrichment and cross-market coverage
3. Salt Edge
Salt Edge has been operating since 2013 and covers both European PSD2 banks and global banks outside the PSD2 framework.
- Coverage: 500+ banks in Europe, plus global coverage
- Pricing: Tiered plans; developer sandbox available
- Certificate required: No
- Best for: Teams needing coverage outside Europe alongside PSD2 banks
4. GoCardless (Formerly Nordigen)
After acquiring Nordigen, GoCardless integrated the open banking data API into their broader payment platform. The Nordigen API still works but is increasingly bundled with payment initiation products.
- Coverage: 2,300+ banks in 31 European countries
- Pricing: Free tier still available (with limits); paid tiers bundled with GoCardless payment products
- Certificate required: No
- Best for: Teams already using GoCardless for direct debit payments
5. open-banking.io (Cert-Free Direct API)
For developers who want to connect to European bank APIs directly without an aggregator — and without the eIDAS certificate cost — open-banking.io provides a PSD2-compliant API layer that handles the bank connection protocol without requiring you to purchase a €2,000-6,000 annual QWAC certificate.
- Coverage: European banks supporting Berlin Group NextGenPSD2 or UK Open Banking standards
- Pricing: No per-call fees; self-hostable
- Certificate required: No — the cert-free architecture is the core differentiator
- Best for: Developers, self-hosters, and small businesses that want direct bank connections without aggregator markups or certificate overhead
Comparison Summary
| Feature | Nordigen/GoCardless | TrueLayer | Tink | open-banking.io |
|---|---|---|---|---|
| Pricing model | Free tier + usage | Per-call | Enterprise | No per-call fees |
| Certificate needed | No | No | No | No |
| Self-hostable | No | No | No | Yes |
| Bank coverage | 2,300+ EU | 1,500+ EU/UK | 6,000+ global | EU PSD2 banks |
| Data enrichment | Basic | Yes | Advanced | No |
| Payment initiation | Yes (via GoCardless) | Yes | Yes | Read-only focused |
How to Choose
Choose an aggregator (TrueLayer, Tink, Salt Edge) if you need:
- Maximum bank coverage with a single integration
- Data enrichment (merchant identification, categorization)
- Payment initiation alongside account data
- A managed service with SLAs
Choose a direct/self-hosted approach (open-banking.io) if you need:
- No per-call or per-account fees
- Full control over your data pipeline
- Self-hosting on your own infrastructure
- Read-only account information without payment initiation complexity
Stay with Nordigen/GoCardless if you:
- Are already integrated and the API meets your needs
- Use GoCardless for payments and want unified billing
- Need the free tier for low-volume use
The Certificate Question
The single biggest barrier to direct PSD2 API access has been the eIDAS QWAC (Qualified Website Authentication Certificate) requirement. These certificates cost €2,000-6,000 per year and require an extended validation process with an eIDAS-qualified trust service provider.
This is precisely why aggregators like Nordigen gained traction: they absorb the certificate cost and complexity. The emerging alternatives — including cert-free approaches — aim to remove this barrier so that individual developers and small businesses can access bank data directly.
Conclusion
The Nordigen alternative landscape in 2026 is healthy and diverse. Managed aggregators like TrueLayer and Tink offer convenience and enrichment at a per-call cost. Direct API approaches like open-banking.io offer independence and cost predictability for teams willing to handle integration themselves. The right choice depends on your team size, budget, and whether you value managed convenience over architectural control.
