About


Dear Ajv users!
I ask you to support the development of Ajv. 🙏

Since 2015 Ajv has become widely used, thanks to your help and contributions:
  • 🏗 90 contributors
  • ⚙️ 5,000 dependent npm packages
  • ⭐️ 7,000 GitHub stars, from all over the world
  • 🚀 5,000,000 dependent projects on GitHub
  • 💯 120,000,000 npm downloads per month! 

Your donations will fund further development - small and large improvements, support of the next versions of JSON Schema specification, and, possibly, the code should be migrated to TypeScript to make it more maintainable.

I will greatly appreciate anything you can help with to make it happen! 🙏
