About DevKit

DevKit is a collection of 14 focused tools for everyday programming tasks, from formatting JSON to checking CIDR ranges. No account is required.

Tool inputs are processed by JavaScript in your browser. Each tool documents examples and supported behavior. The aim is useful, understandable output with explicit errors when an input cannot be handled.

This is an early release. Check important results against your application requirements, especially when working across shell environments and timezones.
