What can you build with JSON storage?

JSON storage is a Developer Tools API. Developers commonly use developer tools APIs for:

  • automating code review and quality checks
  • integrating CI/CD pipelines and build systems
  • managing feature flags and A/B tests
  • monitoring errors and application performance
  • generating and validating test data

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. JSON storage is free to use, making it a low-risk choice to experiment with.
