The short version

  • Only Zeplo has a free tier, so it costs nothing to try first.
  • Each has a real cost: 10x Banking engagements are multi-year core replacement programmes with costs dominated by migration and integration, so the licence is a minority of what you actually spend.; 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: 10x Banking covers SuperCore ledger, 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.

10x Banking

  • Engagements are multi-year core replacement programmes with costs dominated by migration and integration, so the licence is a minority of what you actually spend.
  • The customer list is small and concentrated in large institutions, which makes reference checking and benchmarking difficult before committing.
  • It is a smaller vendor than Temenos or Finastra carrying a systemically important workload, and bank procurement teams treat that concentration as a genuine risk.
  • Product configuration replaces code but shifts complexity into configuration governance, which banks must staff and control just as carefully as software releases.
  • Value only appears after migration, so a programme cancelled or paused mid-transition leaves the bank running two cores and paying for both.

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

10x Banking: Who is 10x Banking for?

Large incumbent banks running core replacement, not challengers or fintechs looking for a quick launch.

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

10x Banking: How long does implementation take?

Years rather than months. Migration design and coexistence with the legacy core dominate the timeline.

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.

10x Banking: Is pricing published?

No. It is a quoted multi-year enterprise licence scaled by accounts, transaction volume and product lines.

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.
