The short version

  • Only Zeplo has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Zeplo zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • They diverge on capability: Bud Financial covers Transaction enrichment, Zeplo covers URL prefix interface.
  • Prices and features above were last checked on 31 August 2026.

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  • Pricing is unpublished and blends a committed fee with usage, so an institution whose enriched volume grows faster than the value it extracts can find the contract repricing against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

Zeplo

  • Zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • The free Developer tier includes only 500 requests a month and one team member, so it is a demonstration allowance rather than a usable free plan for anything real.
  • Overage on the Developer tier is 20 US dollars per 100,000 requests, two hundred times the marginal rate on the Company tier, so exceeding the free allowance without upgrading is expensive.
  • Team members cost 15 US dollars each beyond the plan allowance, which is an odd charge on an infrastructure product billed by request volume.
  • Log retention is 30 days on both published tiers, so anything requiring longer audit trails on job execution has to be logged separately.

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.

Zeplo: How does Zeplo work?

You prefix your endpoint URL with zeplo.to and add query parameters for retries, delay, cron or concurrency. No SDK or broker is needed.

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.

Zeplo: What does it cost?

Free for 500 requests a month; 39 US dollars a month for a million requests, then 10 dollars per additional million.

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.

Zeplo: Is it suitable for critical jobs?

It is a small vendor in your execution path with no published SLA below Enterprise, so weigh that against the convenience.

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.

Zeplo: Does it work with serverless platforms?

Yes, that is its main use, covering Vercel, Cloudflare Workers, Netlify and similar environments that lack long-running workers.
