About SchemaInterface
The infrastructure required for deterministic data contracts.
The Problem
In microservice architectures, data structures mutate over time. An enum value is added; a required field is dropped; a string format narrows. When these changes occur without explicit, machine-readable contracts, downstream services fail unpredictably.
JSON Schema was designed to solve this. However, the ecosystem around it is fragmented. Validators disagree on edge cases. References ($ref) are handled inconsistently. Code generators often resort to any types when encountering complex polymorphism.
Our Mandate
SchemaInterface was built to provide absolute determinism. If our engine marks a schema as valid according to Draft 2020-12, it is strictly valid. We do not support loose parsing, legacy fallbacks, or proprietary extensions without explicit configuration.
Telemetry in Open Tools
Our web tools execute entirely in your browser. We log absolutely nothing about your data structures.
Test Suite Coverage
Our core engine passes the official JSON Schema test suite for core, validation, and format requirements.
The Team
We are a small team of infrastructure engineers who spent too many years debugging TypeError: Cannot read property of undefined in production environments resulting from undocumented API payload changes. We believe contracts should be enforced by tooling, not human vigilance.
Join the effort
We are hiring systems engineers with deep knowledge of parsers and compilers.
