JSON Schema is at the core of your governance program, but working with it shouldn't be a headache. Our self-hosted registry eliminates the complexity of operating schemas at scale. Led by a member of the JSON Schema Technical Steering Committee.

Great organisations rely on our tooling
Designed to solve schema management at scale
We live and breathe JSON Schema—as expert consultants, book authors, award-winning researchers, and open-source maintainers. This isn't just another registry; It's the result of years of insights operating JSON Schema in production.
Browse, search, and dereference your collections of schemas, even across multiple GitHub repositories, from a single place

Stop reinventing the wheel. We ship hand picked industry standard ontologies that you can plug into your API specifications right away

Dependency-free (not even a database), stateless, horizontally-scalable, and customisable with a simple JSON configuration file

Written in C++ and powered by Blaze, the world's fastest JSON Schema validator, proven by research to be at least 10x faster that alternatives

Forget about JSON Schema drafts and dialects. Use the version you know and let us convert to any target your tooling demands, on the fly
Level up your API Governance program with ever-evolving statistics to flag anti-patterns, invalid schemas, overly loose schemas, and more

I'm Juan Cruz Viotti, founder of Sourcemeta, member of the JSON Schema Technical Steering Committee, O'Reilly author, and award-winning University of Oxford alumnus.
I'd love to discuss how JSON Schema, OpenAPI, and Sourcemeta tooling can help you build world class APIs.
- Over 75% of API developers make use of JSON Schema
- Over 90% of those developers waste time with substandard schema tooling
- Over 80% of those developers get stuck when writing non-trivial schemas

JSON Schema is ubiquitous and critical to our operations, yet so many of us have barely scratched the surface when it comes to putting the specific to work, let alone getting our house in order
