As a web developer, I frequently work with large JSON payloads, API responses, and sensitive config files.
One thing that always bothered me was pasting confidential API payloads, customer data, or JWT tokens into random online JSON formatters. Many popular online tools send your data to remote cloud servers for formatting, creating an unnecessary privacy and compliance risk.
To solve this, I built ToolInPocket — a free suite of in-browser productivity utilities built with modern JavaScript and HTML5 APIs.
The Client-Side Advantage
Our core tool, the JSON Beautifier & Formatter, executes 100% inside your local browser's V8 engine:
- Zero Server Requests: Your payloads never leave your computer or device.
- Instant Speed: Real-time syntax validation, indentation formatting (2-space, 4-space, tabs), and minification without network latency.
- Safety: Safe for enterprise tokens, HIPAA, and GDPR environments.
We also built companion tools like a side-by-side Text Diff Checker and client-side Base64 Codec.
I would love to hear feedback from the developer community! What utilities or features would you find most useful?
