Open Finance Aggregators Compared: Plaid, MX, TrueLayer, Tink and More
One consented API instead of thousands — and what to do where aggregators don't reach
============================
INTRODUCTION
--------------------
Open finance is bigger than open banking: it spans banking, investments, pensions, insurance, credit and tax. Between your product and thousands of financial institutions sit the data aggregators — providers presenting one consented API instead of many. They are the fastest route to coverage, where they operate. But regulations and aggregators reach only a fraction of the world's finance apps, which is why knowing who covers what — and what to do about the gaps — matters before you build.
POPULAR PROVIDERS
--------------------
The major open-finance aggregators and API providers profiled in the directory:
• Plaid — the best-known US aggregator, covering US, Canada, UK and Europe with bank and card account data via one consented API.
• MX — a major US aggregator for US and Canada, emphasising data quality and enhancement, closely aligned with the FDX standard.
• TrueLayer — a leading UK/European open-banking aggregator for account data (AIS) and payment initiation (PIS), built on PSD2.
• Tink — a major European aggregator now owned by Visa, with broad EU/UK account-data coverage over PSD2 rails.
• Yodlee (Envestnet) — a long-standing US aggregator with deeper investment and wealth-data reach than most.
• Akoya — a US, bank-owned aggregator connecting over FDX-aligned APIs only, with no credential scraping.
• Finicity (Mastercard) — strong in US/Canada consumer-permissioned data for lending and credit decisioning.
• Belvo — the leading open-finance aggregator for Latin America, covering bank, tax and employment data in Brazil and Mexico.
• Salt Edge — unusually broad geographic reach, with thousands of institutions across Europe and Asia-Pacific.
• Yapily — open-banking infrastructure for the UK and Europe, aimed at teams building products on top of the rails.
WHAT CAN BE INTEGRATED
--------------------
• Bank and card account data through one consented API (Plaid, MX, Akoya, Finicity)
• Account information services (AIS) and payment initiation (PIS) over PSD2 rails (TrueLayer, Tink, Yapily)
• Investment and wealth data beyond plain bank accounts (Yodlee)
• Tax and employment data in Latin America (Belvo)
• Consumer-permissioned data for lending and credit decisioning (Finicity)
• Authorized, protocol-layer data-export integrations for apps no aggregator reaches
USE CASES
--------------------
[1] Credit and lending — consumer-permissioned account data feeds underwriting and credit decisioning models.
[2] Personal finance products — aggregate bank and card accounts from thousands of institutions behind one API.
[3] Payment initiation — trigger account-to-account payments over UK/EU PSD2 rails instead of cards.
[4] Wealth and investment tools — pull holdings and investment data, not just checking balances.
[5] Coverage gaps — for the specific banking, investing, lending or insurance app you actually need, where official APIs fall short, an authorized protocol-layer integration delivers a documented data export you run in your own environment.
WHY AUTHORIZED INTEGRATION
--------------------
✓ Consent-based by design — aggregators and FDX-aligned providers like Akoya avoid credential scraping entirely.
✓ Standards-aligned — FDX, PSD2 and the UK Open Banking Standard keep integrations maintainable as rails evolve.
✓ Fastest route to coverage — one aggregator API replaces thousands of bespoke bank connections, where it operates.
✓ A real answer for the gaps — where no aggregator reaches, authorized protocol-layer analysis yields a documented integration you control.
CONCLUSION
--------------------
Choosing an aggregator comes down to geography, data type and standard: Plaid or MX for North America, TrueLayer, Tink or Yapily for UK/Europe, Belvo for Latin America, Salt Edge for broad multi-country reach. And for the finance apps none of them cover, authorized protocol-layer integration fills the gap.
