Everyday developer utilities — JSON formatting, regex testing, JWT decoding, SQL generation, CSS tools and a full HTTP status reference. Built for quick, no-context-switch lookups while you're actually coding.
Frequently Asked Questions
Is it safe to paste tokens or credentials into these tools?
Formatting and decoding tools (JSON, JWT, regex, YAML) run entirely in your browser — nothing is sent to a server. As general practice, still avoid pasting production credentials into any online tool.
Does the AI SQL generator work with my specific database?
It generates standard SQL compatible with MySQL, PostgreSQL and SQLite — always review generated queries against your actual schema before running them, especially anything that modifies data.
Can I use these tools without an internet connection?
Client-side tools like the JSON formatter, regex tester and color tools work offline once the page has loaded. AI-powered tools like the SQL generator need a connection.
