DevT Pro

DevT Pro brings more than 100 everyday developer tools into one fast, keyboard-friendly desktop app. Convert, format, validate, inspect and generate data without sending anything to a server.

• Convert between JSON, XML, YAML, CSV, TSV, TOML and TOON
• Generate Java, C#, TypeScript, Python, Dart and Kotlin models from JSON
• Format, minify and validate JSON, XML, YAML, SQL, HTML, CSS and JavaScript
• Encode and decode URLs, Base64 and JWTs, with tree and table viewers for structured data
• Generate hashes, encrypt text, and create UUIDs, ULIDs, passwords and secret keys
• Test regular expressions, compare text, convert timestamps and parse cron expressions
• Generate and read QR codes

Quickly find any tool with the command palette, work across multiple tabs, and drag files directly into supported editors.

DevT Pro is free to use with a limited set of tools. A one-time license key, bought from a link in the app, unlocks every tool, the devtpro command line, the MCP server and deep links.
