Comparison
Schemato vs json2ts
"json2ts" refers to a family of small online tools that turn a JSON payload into a TypeScript interface. Schemato does the same — and a dozen other things. Here's how they line up.
TL;DR
- • Use Schemato when you also need Zod / Pydantic / Go / Rust output, or when your input is JSON Schema / OpenAPI / SQL instead of raw JSON.
- • Use json2tsif all you ever convert is JSON to TypeScript and you don't want extra options on the page.
- • Both run free in the browser; pick the one whose URL you remember.
Feature-by-feature
| Feature | Schemato | json2ts (typical) |
|---|---|---|
| Input formats | 10 (JSON, JSON Schema, OpenAPI 3.x, GraphQL, SQL DDL, Protobuf, Prisma, TypeScript, Mongoose, Avro) | Mainly JSON |
| Output languages | 15 (TS, Zod, Yup, Joi, Pydantic, Python dataclass, Go, Rust, Swift, Kotlin, Java, C#, Dart, PHP, Ruby) | TypeScript only (per the name) |
| Zod / Yup / Joi outputs | Yes — first-class | No (TypeScript types only) |
| Per-conversion permanent URL | Yes — every X→Y has its own page | Single tool URL |
| Multiple sample tabs | 3-5 real-world samples per input (User profile, e-commerce order, GitHub issue, Stripe charge, etc.) | Single default field |
| Step-by-step usage guide | /guides/json-to-zod and 3 more | Minimal docs |
| Browser-only, no server | Yes — all conversion is client-side | Some implementations submit input to a backend |
| Open source | MIT, GitHub-hosted | Multiple tools share this name; some are open source, some aren't |
| Familiarity / search rank | Newer (less name recognition) | Common search term — many tools rank for it |
| Single-purpose simplicity | Multi-format menu | If you only ever do JSON → TS, the focused UX is fine |
Pick Schemato if you ever need…
- • Zod / Pydantic / Yup / Joi. json2ts produces TypeScript types only. Schemato adds the four most popular validation libraries.
- • Inputs other than raw JSON. JSON Schema, OpenAPI, GraphQL, SQL, Protobuf, Prisma, Mongoose, Avro.
- • A URL you can pin in a runbook. Each conversion has its own page so you can drop a permalink into your team docs.
- • Step-by-step guides. Schemato's /guides section walks through real workflows like fetch validation and React Hook Form integration.
