The short version

  • 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; React Native the JavaScript bridge has historically been a bottleneck for animation-heavy and list-heavy screens, though the New Architecture addresses much of it
  • They diverge on capability: curl covers HTTP/HTTPS, React Native covers Renders to native components.
  • Prices and features above were last checked on 30 August 2026.

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

React Native

  • The JavaScript bridge has historically been a bottleneck for animation-heavy and list-heavy screens, though the New Architecture addresses much of it
  • Upgrading between versions has a reputation for being painful, particularly with many native dependencies
  • Anything the framework does not wrap requires native code in Swift or Kotlin, so a purely JavaScript team can still get stuck
  • Because it renders to real platform components, small behavioural differences between iOS and Android surface in your code rather than being hidden

Answered from the vendors’ own pages

curl: How much does curl cost?

curl is free and open-source software under the GPL 3.0 license. There is no cost to download, use, or modify the software.

Source
React Native: Is React Native free?

Yes. React Native is open source from Meta with no licence fee, and it is free for commercial use.

curl: Is commercial support available for curl?

Yes. The curl website references 'commercial support available,' but pricing and details are not disclosed on the homepage and require visiting the support page.

Source
React Native: Does React Native produce a real native app?

Yes. JavaScript primitives render to the platform’s own UI components using the same native APIs a Swift or Kotlin app would call, rather than to a web view.

curl: Can I sponsor curl financially?

Yes. The curl website offers an option to 'Sponsor curl financially.' Visitors can donate to support curl development, but the donation link must be accessed through the site's support section.

Source
React Native: Which well-known apps use React Native?

Meta cites Facebook, Microsoft Office, Teams and Outlook, Amazon Shopping, Discord, Coinbase and Tesla among thousands of apps built with it.

React Native: Should I use Expo or plain React Native?

Expo handles builds, updates and native configuration for you and is the recommended starting point. Plain React Native gives full control of the native projects, which matters when you need native code the managed workflow does not cover.
