Pricing

Free Tool Suite

Free, no account required, no rate limits. Ad-supported.

JSON/YAML formatting, Base64, JWT decoding, CSV/XML conversion, diffing, and more — see the full tool list.

Living Types

Currently free, no account required, during initial launch. Paste sample API responses, get inferred TypeScript types and Zod validators, save a snapshot, and catch contract drift when a real response changes shape.

A paid Pro tier with additional features is planned for later — nothing you build with the free tier today will be taken away or paywalled retroactively. Try it at /generate.
