## What it is
DevToys is a free, open-source, offline desktop application bundling 30+ small developer utilities such as converters, encoders/decoders, formatters, generators, testers, and text tools. It runs on Windows, macOS, and Linux, supports clipboard-based Smart Detection, a CLI mode, and an SDK for building extensions.

## Use cases
- convert json to yaml offline
- decode base64 or jwt without websites
- format and validate json sql xml
- generate hashes passwords and uuids
- compare two text files
- test regex expressions
- compress png jpeg images locally
- run dev utilities from the command line in ci

## When to choose
- you want offline, privacy-focused alternatives to random web tools
- you need a single cross-platform app for many small dev tasks
- you want clipboard-aware smart tool detection
- you want to extend a tool suite with your own utilities via an SDK

## When to avoid
- you need a single deeply specialized tool rather than many small ones
- you require a purely terminal-only workflow with no GUI
- you need tools on mobile or in the browser
