Top 10 European Open Banking Platforms

Nordigen, now operating as GoCardless Bank Account Data following its 2022 acquisition by GoCardless, offers free-tier account information services. This offering supports over 3,000 developers, which is a distinctive feature in the open banking landscape. The platform combines Nordigen's EU-wide coverage with GoCardless's global direct debit network, facilitating seamless data access for applications like credit scoring and verification. While the free tier for account information is a significant advantage, the integration with GoCardless means its primary focus has shifted towards bank account data and direct debits, potentially specializing its services rather than offering a comprehensive open banking suite.

Token.io focuses on open payments, connecting 500 European banks to enable real-time account-to-account transactions for merchants and PSPs.
