I work on code generator that creates TypeScript SDKs from OpenAPI specs and Zod (
https://zod.dev/) is a critical building block that I chose to power runtime validation in those SDKs. Depending on the complexity of a Zod schema, the resulting validation error message can contain a wall of JSON text - the serialised issues that were recorded during validation.
I wanted to try and create a small tool to help me better visualise and parse these errors. In code and the command line, we do also have the ability to pretty-print the errors but I still wanted a web UI which can let me share URLs for visualised errors.
I'm still iterating on it but would love any feedback if you do get to try it out.
