LocalOnly: toolkit for JSON & developers - The privacy-first toolkit for JSON & developers - localonly

Hi Product Hunt 👋 I'm Kiran. I built LocalOnly because I kept pasting API responses, JWTs and config files into online tools without knowing where that data went. LocalOnly puts 37 developer tools in one place, and every one of them runs in your browser. You can format and compare JSON, test JSONPath queries, convert between JSON, YAML, CSV and XML, decode JWTs, generate UUIDs, hash files and draw PlantUML diagrams, all without uploading what you paste. What makes it different: The PlantUML editor renders diagrams in your browser, with no server and no Java, and exports PNG and SVG Share links carry the data inside the link itself, optionally protected with a password It works offline once loaded, and you can install it as an app Every tool has a guide with tested JavaScript and Python examples It's free and needs no account. I'd love your feedback, especially on which tool you'd like next. 👉 https://localonly.dev/
