Free Online Generators
Some things you need in every project but don't want to build from scratch: unique IDs, cron schedules, properly formatted meta tags, server configs. These generators produce exactly what you need with correct syntax so you can paste and ship instead of debugging typos in config files.
The cron generator is particularly useful because cron syntax is notoriously hard to read. Instead of guessing whether */5 * * * * means every 5 minutes or every 5th minute, you build the schedule visually and see the next 5 run times before committing to it. Same idea with .htaccess: pick your redirects and caching rules from dropdowns instead of memorizing Apache directives.
Everything runs client-side. Your UUIDs, hashes, and environment variables stay on your machine.
