The short version

  • Only Apidog has a free tier, so it costs nothing to try first.
  • Each has a real cost: Apidog free plan is capped at 4 users, limiting larger teams from using it at no cost.; Codat the accounting platforms are metering developer access themselves, with Xero introducing tiered connection based developer pricing from 2 March 2026, so a cost you do not control has been inserted between you and the data and it scales with the number of customers you connect.
  • They diverge on capability: Apidog covers API design and documentation, Codat covers Normalised accounting API.
  • 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.

Apidog

  • Free plan is capped at 4 users, limiting larger teams from using it at no cost.
  • Faster scheduled imports and unlimited projects require the Professional tier or higher.
  • Smaller community and plugin ecosystem compared to long-established tools like Postman.
  • Advanced enterprise security controls require the top-tier Enterprise plan.

Codat

  • The accounting platforms are metering developer access themselves, with Xero introducing tiered connection based developer pricing from 2 March 2026, so a cost you do not control has been inserted between you and the data and it scales with the number of customers you connect.
  • Pricing is opaque and enterprise shaped for a product developers expect to evaluate technically first, so build decisions get made before anyone knows the unit economics.
  • Normalisation hides but does not remove the underlying differences between accounting systems, and edge cases in multi-currency, journals and tax handling surface as data quality problems that your team must reason about in each source system anyway.
  • Data quality depends on the small business keeping its books properly, so a lender using ledger data for underwriting inherits the bookkeeping standard of its worst borrower and needs its own validation layer regardless.
  • Connection breakage from expired tokens and platform API changes is an ongoing operational load, and a borrower whose connection lapses stops being monitored silently, which is the failure mode that matters most in a lending portfolio.

Apidog: Can I try paid plans before subscribing?

Paid plans include a 14-day free trial, giving teams full access to premium features before committing to a subscription.

Codat: Is pricing published?

No. It is quoted by connected companies, data types and products, and users consistently describe it as opaque.

Codat: Does it replace bank data aggregation?

Not entirely. It covers banking alongside accounting and commerce, but lenders commonly run it beside a bank aggregator for transaction level cash flow.
