Practical tools for everyday development

Snappo brings common developer utilities together in one place: format and validate JSON, test regular expressions, preview cron schedules, generate passwords, and inspect color values without installing another app.

Many tools run directly in your browser. Each tool page explains how its input is handled, so you can check before working with sensitive data.
