The short version
- Only curl has a free tier, so it costs nothing to try first.
- Each has a real cost: curl open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply; Moov the 500 US dollar monthly minimum makes Moov unattractive below roughly 80,000 dollars a month of card volume, since the minimum rather than the rate becomes your effective price.
- They diverge on capability: curl covers HTTP/HTTPS, Moov covers Interchange-plus card acceptance.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
curl
- Open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply
- Commercial support costs hidden: site references 'commercial support available' but pricing is not detailed or accessible from homepage
- No SaaS model: curl is a command-line tool and library; costs are limited to optional commercial support contracts (pricing unknown)
- Self-support burden: free software means customers rely on community forums or undisclosed commercial support pricing
Moov
- The 500 US dollar monthly minimum makes Moov unattractive below roughly 80,000 dollars a month of card volume, since the minimum rather than the rate becomes your effective price.
- The 50 cent monthly charge per active wallet penalises platforms with many end users who transact rarely, and that cost grows with your user base rather than your revenue.
- United States only, so any platform with international sellers or buyers needs a second provider and a second reconciliation process.
- At very high volume the published interchange-plus markup is less competitive than a directly negotiated acquiring relationship, so success eventually creates a reason to leave.
- The ecosystem of prebuilt integrations, plugins and third-party tooling is far smaller than Stripe's, so anything outside the core API, from tax handling to subscription logic, is work you build yourself.
