Plaid is strongest in North America (US and Canada) and is widely used for account linking, transaction data, income verification, and identity signals. It also offers UK and European coverage. TrueLayer is UK- and Europe-focused and is often chosen for payment initiation (pay-by-bank, instant bank-to-bank payments) as well as account information. Both offer a single API to many banks.

Choose Plaid if your primary market is the US or Canada or you need deep data and verification features; choose TrueLayer if you are building in the UK or Europe and need strong pay-by-bank or a payments-first API. The Open Banking Tracker compares API aggregators by country and product type (AIS/PIS) so you can evaluate both and others.
