DevTools - 23 free browser-based dev tools. Nothing leaves your browser

by•
SAM Toolkit is a collection of 23 free developer tools — JSON formatters, converters, encoders, and more — that run 100% in your browser. No file uploads, no server processing, no data collection. Everything happens client-side, so your code and data never leave your machine. Built with Blazor for a fast, snappy experience without the usual "paste your sensitive data into a random website" anxiety. Would love your feedback — what tools would you want added next?

Hey Product Hunt! 👋 I built SAM Toolkit because I was tired of using online dev tools that quietly send your data to a server — especially annoying when you're working with anything sensitive (API keys, internal JSON, etc). Every tool here runs entirely in your browser using Blazor/WebAssembly. I'm actively adding new tools based on what people ask for, so drop a comment if there's something you use daily that you wish existed as a quick browser tool. Thanks for checking it out!
