Helpful Tools V2 - Privacy-focused local developer toolkit, a gift to all devs

As developers, we constantly switch between online tools for formatting JSON, testing regex, comparing text, and more. But these tools often: - Send your data to external servers - They are cluttered with ads - Require sign-ups So I built Helpful Tools v2 - a privacy-focused developer toolkit that runs entirely on your local machine as a Python process. Just install, clone the project, and execute the start.sh inside the project. I have added a ton of test cases to verify the accuracy of the tools in the frontend and backend. I will continue to add more and refine. What's included: - JSON/YAML formatters & validators - JSON-YAML-XML converter - Text diff viewer - Regex tester with live highlighting - Cron expression parser - Scientific calculator with graphing - JWT decoder - Data sources manager (S3, HTTP, SFTP) - And more to come... Why use it? - Privacy-first - All processing happens locally, your data never leaves your machine - No ads, no tracking - Just tools that work - Fully configurable - Enable/disable tools as needed - Modern UI - Clean, responsive interface - Open source - MIT licensed, contributions welcome Tech stack: Python, Flask, JavaScript If you find it useful, a star on GitHub would mean a lot! #OpenSource #DeveloperTools #Python #Flask #WebDevelopment #Privacy #Programming #SoftwareEngineering #ClaudeCode #JSON #DevTools #CSS #Regex #HTML
