Code Generators
Paste data in, get production-ready code out — TypeScript interfaces, schemas, boilerplate and more.
Stop writing boilerplate by hand
Repetitive code — type definitions, interface declarations, schema boilerplate — is some of the most tedious work in software development. Code generators automate the translation from one format (like a JSON API response) into the code you actually need (like a TypeScript interface), letting you spend time on the logic that matters.

Frequently asked questions
Yes, but review them first. The generators infer types from the data you provide — if a field is null in the sample but could be a string in production, you will need to widen the type manually. Always treat generated code as a starting point, not a final answer.
No. All code generation runs entirely in your browser using JavaScript. Your data never leaves your device.
Not yet, but merging types from multiple samples is on the roadmap. For now, use the most complete sample you have — one that has all optional fields populated.
