The short version

  • Only Zeplo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Vodeno its actual regulatory backing differs by geography, Aion Bank in continental Europe versus NatWest in the UK, so a customer must understand which entity and licence they are actually contracting under rather than assuming one uniform Vodeno product.; 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: Vodeno covers Core banking infrastructure, Zeplo covers URL prefix interface.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Vodeno

  • Its actual regulatory backing differs by geography, Aion Bank in continental Europe versus NatWest in the UK, so a customer must understand which entity and licence they are actually contracting under rather than assuming one uniform Vodeno product.
  • Pricing is entirely unpublished across both the European and UK businesses.
  • The scale of NatWest's investment (up to roughly £120 million) signals a business still working toward profitability, with NatWest itself targeting breakeven within five years of the venture launching, which is a meaningful timeline risk for a customer building long-term infrastructure dependency on it.
  • As banking-as-a-service infrastructure, any customer remains dependent on Vodeno's underlying bank partner maintaining its own licence and risk appetite, which is a layer of dependency beyond Vodeno's own commercial terms.
  • Product scope, such as lending and BNPL availability, may differ between the UK and European entities, so a company operating in both markets should not assume identical capability across the two.

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

Vodeno: Does Vodeno hold its own banking licence?

No, it operates through partner banks, Aion Bank in continental Europe and NatWest in the UK.

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.

Vodeno: Is the UK business the same as the European business?

They are related but distinct entities backed by different bank partners, with different investment structures.

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.

Vodeno: How much has NatWest invested?

A capped commitment of up to roughly £120 million into the UK entity, plus a separate roughly €58 million investment in Vodeno Group for an 18% stake.

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.

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.
