About Developer Tools
Developers spend a huge portion of their time on repetitive tasks — formatting JSON, encoding strings, generating UUIDs, testing regular expressions, and decoding JWT tokens. Our Developer Tools category eliminates that friction with 29 free, fast, browser-based utilities that cover the most common development workflows.
Core utilities like the JSON Formatter, Base64 Encoder, and URL Encoder/Decoder handle everyday encoding and formatting tasks. Debugging aids such as the JWT Decoder, Regex Tester, and Diff Checker speed up problem diagnosis. Code productivity tools including the SQL Beautifier, HTML Formatter, CSV to JSON converter, and Cron Job Generator save significant manual effort. Infrastructure and security tools like Hash Generator, UUID Generator, and Chmod Calculator round out the collection.
All tools work entirely in the browser — sensitive tokens, private keys, and proprietary data never leave your machine. Bookmark this category as your go-to developer toolkit for tasks that are too small to warrant a dedicated application but too fiddly to do by hand.
