Small utilities that run entirely in your browser. Nothing gets sent to a server. Nothing gets logged. For full products, see /apps.
For working with SQL, timestamps, structured data and everything else that runs through a data pipeline. Everything client-side.
Paste ugly SQL, get clean, readable, dialect-aware SQL. Postgres, MySQL, SQLite, BigQuery, Redshift, and more. Every option you'd expect from your IDE.
Generate UUIDs (v1, v3, v4, v5, v7) in any format. Batch up to 1000, download as TXT/CSV/JSON, or grab SQL-ready INSERT rows. Public API included.
Convert between Unix timestamps and human dates in any timezone. Seconds, milliseconds, ISO 8601, RFC 2822. Batch mode and live current-time.
For generating and checking secrets. Passwords, API keys, entropy. Nothing you type or generate ever leaves your browser.
Random passwords, easy-to-read variants, pronounceable passwords, or diceware passphrases. Runs entirely in your browser.
Paste any password and see how strong it really is. Entropy, estimated crack time, and specific suggestions. Never leaves your browser.
Cryptographically secure API keys with prefixes, minimum-character rules, 11 output formats (env, YAML, JS, Python, .NET, Java, PHP, Bash, more), QR transfer, and a paste-in validator.
