Open Bank Project review
An open-source API platform for banks exposing data and services to third parties.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Open Bank Project is an open-source API platform from TESOBE GmbH for financial institutions, regulators and fintech companies. It connects to an organisation’s systems and exposes data and services through prebuilt, standardised endpoints. The product is aimed at banks and other institutions that want to share data with third parties, integrate external services, or manage access to banking APIs—not teams seeking an account-aggregation service that connects to bank feeds. It supports cloud and self-hosted deployment, and is available through web and API interfaces.
Its API-management scope is broad: an API gateway provides access control and rate limiting, while the API manager covers connected applications, roles and entitlements. A developer portal handles API registration and access requests; the browser-based catalogue includes documentation and endpoint testing. Authentication and consent flows, usage analytics and monitoring, and a sandbox with synthetic data support the surrounding work of publishing and testing APIs. The platform supports UK Open Banking and Berlin Group standards, with data types including accounts, payments, KYC, FX and products. This makes it a fit for institutions building an API programme rather than a narrow connector.
According to the vendor’s pricing model, prospective customers should contact sales; the published information does not give a plan-by-plan comparison. The product is open source and can be self-hosted, while cloud deployment is also offered. The listed support channel is community, so buyers should evaluate whether that fits their operational needs, especially for larger deployments. Open Bank Project suits mid-market and enterprise organisations seeking control over API exposure and management. Buyers whose priority is a direct-feed aggregator, or who need a clearly specified commercial tier before engaging with a vendor, should consider alternatives.
