Developer Tools

Developer Tools on ToolsForge is a collection of 50 free, fast utilities — including JSON Formatter, JSON Validator and JSON Minifier — built to run in your browser wherever technically possible, so your files stay on your own device. No installs, no sign-up, and no cost.

About Developer Tools

Developer Tools brings together every tool you're likely to need for this kind of task in one place, so you don't have to bounce between different websites — each with their own upload limits, ads, and account walls — to get a simple job done.

Wherever technically possible, tools in this category are built to run entirely in your browser using modern web technology such as WebAssembly and Web Workers. That means faster results (no upload wait) and stronger privacy (your file never leaves your device). For the rare tool that needs server-side processing, we clearly label it and apply strict automatic deletion — see our Data Processing Policy for details.
