Standout Differences

A data API, a planning platform, and a spend platform — not three rivals

currencylayer answers 'what's the exchange rate,' Datarails answers 'what should we spend and forecast,' and Divvy answers 'how do we actually spend and track it.' They sit at different points in a finance workflow rather than competing for the same budget line.

currencylayer, Datarails, Divvy

currencylayer's precious-metals coverage is a genuine differentiator

Beyond 168 world currencies, currencylayer also covers precious metals pricing in the same JSON API, which is a less common feature among general-purpose FX rate APIs and worth noting for developers who need both in one integration.

Datarails plans ahead, Divvy captures what already happened

Datarails is forward-looking — budgeting, forecasting, and scenario planning built on top of consolidated ERP, CRM, accounting, banking, and HR data. Divvy is largely backward- and real-time-looking — corporate cards and AI-powered expense tracking that captures spend as it happens. Together they could form a plan-and-execute loop rather than compete for the same use case.

Datarails, Divvy

Very different corporate backing and pricing exposure

currencylayer is an apilayer product now owned by Idera Inc., Datarails is an independently operated, Tel Aviv-founded company with custom enterprise pricing, and Divvy has been absorbed into BILL as a free-forward product. Their ownership structures signal how each is likely to price and support you long-term.

Cons

  • Pricing is not published and requires a sales conversation
  • Implementation often requires a separate, sizable professional services engagement
  • Still fundamentally tied to Excel, unlike fully cloud-native FP and A tools

Divvy

Frequently Asked Questions

Are currencylayer, Datarails, and Divvy actual alternatives to each other?

No. They were grouped by category metadata rather than genuine overlap. currencylayer is a foreign-exchange rate API for developers, Datarails is an Excel-native FP&A platform, and Divvy is a spend-management platform with corporate cards. A buyer typically needs at most one of the three for a given problem.

Which is best for a startup that needs free corporate cards?

Divvy (now sold as BILL Spend & Expense). It's a free spend-management platform combining corporate cards, budgeting tools, and AI-powered expense tracking, aimed squarely at small and midsize businesses.

Which is best for a finance team that lives in Excel and needs better forecasting?

Datarails. It's built specifically to let finance teams keep working inside Excel while consolidating data from accounting, ERP, CRM, banking, and HR systems for automated reporting, budgeting, forecasting, and scenario planning.

Is currencylayer useful for anything besides currency conversion?

Yes. In addition to real-time and historical rates for 168 world currencies, currencylayer's API also delivers precious metals pricing in the same JSON format, which is uncommon among comparable FX rate APIs.

Could a company reasonably use more than one of these tools together?

Yes. A common combination would be Divvy for day-to-day corporate card spend and expense capture, Datarails for consolidating and forecasting that spend inside Excel-based FP&A models, and currencylayer if the company needs to build custom multi-currency conversion into an internal tool.
