Developer Tools
Everything related to coding, formatting data, and styling websites.
Developer Tools covers the everyday chores of building and debugging for the web: formatting and validating markup, converting between data formats, and inspecting the systems your code talks to. Start with the JSON Formatter or the SQL Formatter when you need to make messy data readable, check a pattern before it ships with the Regex Tester, translate a schedule with the Cron Generator, and reach for the DNS Lookup when a domain will not resolve. Every tool runs in your browser, so nothing you paste is uploaded.
