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  • Pricing is unpublished and blends a committed fee with usage, so an institution whose enriched volume grows faster than the value it extracts can find the contract repricing against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.

curl

  • Open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply
  • Commercial support costs hidden: site references 'commercial support available' but pricing is not detailed or accessible from homepage
  • No SaaS model: curl is a command-line tool and library; costs are limited to optional commercial support contracts (pricing unknown)
  • Self-support burden: free software means customers rely on community forums or undisclosed commercial support pricing

curl: Can I sponsor curl financially?

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.
