About DevPlaybook

What is DevPlaybook?

DevPlaybook is a collection of free, fast, and privacy-focused developer tools that run entirely in your browser. No data is ever sent to servers — everything happens locally on your device.

Our Tools

• JSON Formatter: Format, validate, and minify JSON with syntax highlighting
• Base64 Encoder/Decoder: Encode and decode Base64 with URL-safe option
• UUID Generator: Generate UUIDs in various formats (v1, v4, v7)
• Hash Generator: Generate MD5, SHA-1, SHA-256, and other hashes
• JWT Decoder: Decode and verify JSON Web Tokens

Why Privacy First?

Many online developer tools send your data to servers for processing. This can be a security risk, especially when working with sensitive data like API keys, tokens, or confidential information.

DevPlaybook processes everything in your browser using JavaScript. Your data never leaves your device, making it safe to use with any data.

Open Source

DevPlaybook is built with modern web technologies including Vue.js, Nuxt, and TypeScript. We believe in transparency and the power of open source software.
