Hey Product Hunt 👋 I built Tool127 as a free, local-first collection of browser-based developer tools for everyday coding workflows. It includes tools for JSON formatting, text comparison, JWT analysis, encoding and decoding, UUID generation, QR code generation, password generation, mock data generation, and color conversion. I created it because these utilities are often scattered across many different websites, with inconsistent interfaces and unclear privacy behavior. Tool127 focuses on: - No login required - Local-first processing where possible - No unnecessary server uploads - Fast access to common developer tools - A clean and consistent interface I’m still improving the platform and would love feedback from developers, QA engineers, technical writers, and product teams.
