about typetools
typetools was built to eliminate the repetitive, error-prone manual transcription of raw data contracts into static and runtime types.
core engineering principles
zero-telemetry client execution
Developers regularly process sensitive production payloads and schemas. TypeTools performs 100% of parsing and AST synthesis inside the browser's Web Worker. Zero bytes are uploaded.
edge-case defense by default
Online converters often collapse under edge cases. We account for IEEE 754 64-bit integer limits, camelCase versus snake_case aliases, and Apache Avro union ordering constraints.
