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
