Developer Tools

Every tool here runs entirely in your browser — your code, data, and inputs never leave your device. There are no server-side API calls, no telemetry, no logging. This makes these tools safe for sensitive data like production credentials, internal SQL queries, or customer JSON payloads.

The JSON, XML, and HTML formatters use the browser's native parsers (JSON.parse, DOMParser) for maximum accuracy. The SQL formatter uses a custom keyword-aware indenter supporting 30+ SQL clauses. The Regex tester wraps the native RegExp with match highlighting and capture group display.

Prefer keyboard shortcuts? Press Ctrl + Enter to run the primary action, Ctrl + L to clear input, and Ctrl + S to download the output.
