Quick answer
CurrencyBeacon - CurrencyBeacon wins for most builders because its free tier is much larger, allows commercial use, and has a clearer path to moderate paid usage, while Currencyapi.com is mainly the better choice only if you need a tiny, no-card starter plan.
How the free tiers compare
The two free tiers solve the same general problem, but they are aimed at different stages. Currencyapi.com is a very small, low-friction sandbox: 300 requests a month, one key, private use only, and no card required. It is enough to test an integration or run a tiny internal tool, but it runs out fast and the commercial restriction matters. CurrencyBeacon gives you a more usable starter lane: 5,000 requests, commercial use allowed, hourly updates, conversion, and historical data back to 1995. That makes it fit a real prototype or small production feature better. The tradeoff is that CurrencyBeacon does not explicitly say no card is required, so it may be a slightly more normal signup flow. After the free tier, both are flat-priced, but Currencyapi.com jumps from 300 requests to $9.99 for 15,000, while CurrencyBeacon starts at $10 for 50,000, so CurrencyBeacon stays cheaper per request as you grow.

After you outgrow the free tier
Both products use flat monthly pricing for their first paid tiers, so the main difference is the step up in included volume. Currencyapi.com starts at $9.99 for 15,000 requests, then $39.99 for 600,000 and $79.99 for 1.7 million. CurrencyBeacon starts at $10 for 50,000 requests, then $99 for 500,000 and $599 for 2 million. For small-team usage, CurrencyBeacon is the cheaper scale-up because the $10 tier covers more traffic than Currencyapi.com’s $9.99 tier. Beyond that, Currencyapi.com remains cheaper at some midpoints, but B includes more requests per dollar at the starter level.

Bottom line
For the most common builder use case, CurrencyBeacon is the better free-tier pick because it gives you enough room to actually build and test a real integration, not just a toy demo. The commercial-use allowance and 5,000-request cap matter more than Currencyapi.com’s no-card signup for most teams. Currencyapi.com is the better niche pick if you only want a tiny private sandbox and care most about avoiding credit-card friction before you commit.
