Where each one falls short

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

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.

Janus Gateway

  • No commercial pricing published; open-source project without official commercial offerings
  • Community-supported only; no vendor commercial support or SLA available

Answered from the vendors’ own pages

Codat: What is changing with Xero in 2026?

Xero is introducing a tiered, usage based developer pricing model effective 2 March 2026, with tiers based on the number of customer connections an app holds. That is a new cost in the chain for anyone reading Xero data at scale, whether directly or through Codat.

Janus Gateway: How much does Janus Gateway cost?

Janus Gateway has no pricing model; it is a free open-source WebRTC server developed by Meetecho. The general-purpose server is available for download at no cost. There are no subscription tiers or commercial licensing fees.

Codat: Can Codat write data back?

Yes. It supports pushing bills, payments and journal entries into accounting systems, not only reading from them.

Janus Gateway: Is Janus Gateway supported commercially?

Janus Gateway is community-supported open-source software with no official commercial support or SLA from the vendors. While Meetecho developed the project, users must rely on community documentation and forums for assistance.

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.
