Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bud Financial

  • It is an enrichment and intelligence layer, not connectivity, so most buyers also pay an aggregator and the total cost of the open banking stack is higher than the Bud contract suggests.
  • Categorisation accuracy is market specific, and merchant coverage tuned for the UK does not transfer cleanly to other countries, so non-UK buyers should insist on accuracy testing against their own data.
  • Sending complete customer transaction histories to a third party triggers a data protection and vendor risk review at any bank, and that process routinely takes longer than the technical integration itself.
  • Pricing is unpublished and blends a committed fee with usage, so an institution whose enriched volume grows faster than the value it extracts can find the contract repricing against it at renewal.
  • The product set spans enrichment, decisioning, staff analytics and consumer features, which means a buyer wanting only enrichment may be steered towards a broader platform commitment than the problem requires.

Spring Cloud Gateway

  • Released under the Apache 2.0 license, free and open source with no commercial tier

Answered from the vendors’ own pages

Bud Financial: Does Bud provide open banking connections?

It can, but its differentiator is enrichment of transaction data. Many customers already have the data and buy Bud to make it usable.

Spring Cloud Gateway: Is Spring Cloud Gateway free?

Yes, Spring Cloud Gateway is free and open-source software. It is part of the Spring ecosystem and available through GitHub repositories with open-source dependencies like spring-cloud-starter-gateway-server-webflux and spring-cloud-starter-gateway-server-webmvc.

Bud Financial: Is it UK only?

It is UK founded and its merchant coverage is strongest there, with expansion into the US. Accuracy outside the UK should be tested on your own data.

Spring Cloud Gateway: What enterprise support is available for Spring Cloud Gateway?

Tanzu Spring provides optional enterprise support including Day 0 access to security patches for organizations requiring guaranteed support, but specific pricing is not published on the Spring Cloud Gateway project page.

Source
Bud Financial: What does it cost?

Not published. Typically a recurring committed fee plus usage-based charges, priced by product mix and enriched transaction volume.

Bud Financial: Why not build categorisation in house?

Because it is not a one-off build. Merchant naming changes continuously and an in-house model degrades unless someone maintains it permanently, which is the cost most institutions underestimate.
