Developer Utilities — Timestamp, UUID, Cron & More

Seven browser-based utilities for everyday engineering work: Unix timestamps, UUIDs, cron next runs, regex testing, password generation, slugify, and number-base conversion. For encoding helpers see Base64.

Back to developer utilities on the hub

Unix Timestamp

Convert epoch seconds or milliseconds to ISO dates and back — UTC or local timezone.

UUID Generator

Generate UUID v4, v7, or nil with hyphen, case, and bulk count options.

Cron Parser

Parse 5- or 6-field cron expressions and list the next fire times.

Regex Tester

Test JavaScript regular expressions with flags, groups, and replace preview.

Password Generator

Generate strong passwords with CSPRNG — length, charset, and ambiguous exclusion.

Slugify

Turn titles into URL-safe slugs with separator, casing, and length options.

Number Base Converter

Convert integers between bases 2–36 with optional byte endianness for hex/bin.

Free developer tools platform — minify, convert, encode and format code online. Fast, modern, and privacy-friendly.
