Developer tools that stay in your browser

Format, decode, test and convert. Every tool runs entirely in your browser: nothing you paste is uploaded, and there is no account to create.

Featured tools

Design a schema, generate the code, and convert between formats: real engineering work, done in your browser.

cURL to Code
Turn a curl command into fetch, Axios, Laravel Http or Guzzle code, in your browser.
Database Schema Studio
Design tables visually and get Laravel migrations, models and more, live.
JSON to Types
Turn a JSON sample into TypeScript, Zod or PHP types, privately in your browser.
SQL to Laravel Migration
Turn MySQL CREATE TABLE statements into Laravel migrations, privately in your browser.

Format, validate, minify, inspect and convert JSON and other structured data in your browser.

Private by design
Your input is processed on your device. There is no upload, no account and nothing stored on a server.
Fast, even offline-ish
Each tool loads only its own code, and heavy work runs in the background so typing stays smooth.
Free, no strings
No sign-up, no limits, no watermarks. Open a tool, use it, close the tab.
