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.
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.
