Hey everyone 👋
I built TonuDevTool to solve a simple problem — developers waste a lot of time switching between different websites for small tasks like formatting JSON, minifying CSS, or encoding data.
So I created a single platform with 200+ tools that are fast, free, and run entirely in the browser — no login, no tracking.
The goal is simple: save time and make developers more productive.
I’d really love your feedback 🙌
