EZTools for Web Developers
A curated collection of free developer tools to speed up your workflow — from JSON formatting and JWT debugging to regex testing and diff checking.
Modern web development involves constant context switching between APIs, configuration files, and debugging sessions. EZTools is built to eliminate that friction. Every utility runs in your browser with zero server uploads, so your code and data stay private.
Why Developers Choose EZTools
- Zero latency: No network requests mean instant feedback as you type.
- Privacy first: Your source code, tokens, and payloads never leave your machine.
- Always available: Offline-capable PWA means these tools work on airplanes, coffee shops with bad Wi-Fi, or locked-down corporate networks.
Essential Tools for Daily Development
JSON Formatter
APIs speak JSON, but raw payloads are rarely readable. Paste messy JSON into the JSON Formatter to validate syntax, beautify structure, and locate errors down to the exact character.
JWT Decoder
Debugging authentication flows requires inspecting tokens. The JWT Decoder splits any JWT into its header, payload, and signature — instantly and safely.
Regex Tester
Regular expressions are powerful but notoriously hard to get right. The Regex Tester lets you test patterns against live input with real-time match highlighting.
Diff Checker
Reviewing code changes or comparing configuration files? The Diff Checker highlights insertions and deletions with a clean side-by-side view.
