Developer.
Professional developer utilities built for speed and privacy. JSON validation, SQL formatting, Base64 encoding, and RegEx pattern testing — all executed locally, zero data leakage.
JSON Code Health
Validate, prettify, and minify JSON with RFC 8259 compliance checking. Inline error reporting, one-click copy output, and 100% client-side execution — your API keys never leave the browser.
Query Forge
Prettify and minify SQL queries instantly. Keyword capitalization, newline formatting, and whitespace normalization for SELECT, JOIN, WHERE, GROUP BY, and all major SQL clauses.
Safe Cipher
Encode plaintext to Base64 or decode Base64 sequences back to readable text. Error-tolerant with clear invalid-sequence reporting. Safe for production data strings and binary buffers.
RegEx Sandbox
Test PCRE2 patterns with live match highlighting. Supports i/m/s flags, shows match text and offsets, and includes quick-load presets for Email, URL, Digits, and IPv4 patterns.
