The short version

  • Only Zeplo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Salt Edge coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.; 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: Salt Edge covers Account information, Zeplo covers URL prefix interface.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Salt Edge

  • A fintech that wants an aggregator not owned by a card network because its use case competes with card productsnot Zeplo
  • An accounting or treasury product that needs bank feeds in markets the large aggregators do not servenot Zeplo
  • A bank that must publish PSD2-compliant APIs and would rather buy the compliance layer than build itnot Zeplo

Zeplo

  • A Vercel or Cloudflare Workers application that needs retried background jobs without deploying a separate always-on workernot Salt Edge
  • A team that wants a webhook receiver protected by a concurrency limit so a burst does not overwhelm a downstream APInot Salt Edge
  • A small product needing cron jobs against HTTP endpoints without adding a scheduler to its infrastructurenot Salt Edge
  • A developer adding idempotent retries to an unreliable third-party API call with a one-line URL changenot Salt Edge

Where each one falls short

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

Salt Edge

  • Coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.
  • Pricing is not published and is usage-based, so two providers cannot be compared without running both sales processes, and cost grows with the connected user base rather than with revenue.
  • Support and engineering are distributed across Eastern Europe and Canada, and buyers in other time zones report slower turnaround on connection-specific breakages than they get from a domestic provider.
  • PSD2 consent rules require customers to reauthenticate periodically, and Salt Edge cannot change that, so any product depending on continuous data must design for consent expiry and the drop-off it causes.
  • United States coverage is weaker than Plaid or Mastercard Open Banking, so a company with meaningful US volume ends up running two aggregators and normalising between them.

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

Salt Edge: Who owns Salt Edge?

It is independently owned, unlike Tink (Visa), Finicity (Mastercard) or Yodlee (Envestnet), which matters if your use case competes with the owner.

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.

Salt Edge: Is all coverage direct bank API?

No. Inside PSD2 markets connections use regulated APIs; elsewhere coverage relies on direct connections whose reliability depends on the bank not changing its systems. Ask for a per-institution answer.

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.

Salt Edge: Does it do payments as well as data?

Yes, payment initiation is supported in European markets where PSD2 applies.

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.

Salt Edge: What does it cost?

Not published. Pricing is usage-based and quoted, though the sandbox is free.

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.
