Helpful Tools v2 is a comprehensive web-based developer toolkit built with Flask that provides simple, fast, and privacy-focused utilities for developers. The application runs entirely locally, ensuring that no data is sent to external servers while offering a range of essential development tools.
The toolkit includes 11 developer tools covering various needs: JSON/YAML formatters and converters, text diff viewer, regex tester, cron parser, scientific calculator, JWT decoder, sources manager, and AWS Step Functions viewer. Each tool maintains history tracking capabilities, allowing users to save and retrieve their work across sessions. The system is fully configurable, enabling users to enable or disable specific tools based on their requirements.
The application operates entirely locally using Flask framework, processing all data on the user's machine without external dependencies for core functionality. This privacy-first approach ensures sensitive data like JSON payloads, JWT tokens, and regular expressions never leave the local environment.
Benefits include improved developer productivity through consolidated tool access, enhanced data privacy through local processing, and customizable workflows via tool configuration. Use cases span JSON/YAML formatting and validation, regular expression testing and debugging, text comparison for code reviews, JWT token analysis, and AWS Step Functions visualization.
The toolkit targets developers, system administrators, and technical professionals who need reliable, privacy-conscious development utilities. It integrates with various data sources including local files, S3 buckets, SFTP servers, and HTTP endpoints through its sources manager functionality.
