Hey everyone 👋 I built Multi DevTools because I was constantly switching between different tools for simple tasks like formatting JSON, converting data, or minifying code. It felt slow and frustrating. So I decided to put everything in one place — fast, simple, and free. One thing I found interesting while building this: converting JSON to TOML can actually help reduce payload size, which is useful when working with AI tools and APIs. Would love your feedback, suggestions, or even criticism 🙌
