Maker
📌
Hey Product Hunt 👋
I’m an independent developer from Indonesia and the solo maker behind CodingTool.dev.
I started building CodingTool.dev because I was constantly jumping between different websites for small but recurring tasks—formatting JSON, converting data, comparing code, testing regular expressions, generating mock data, and many other everyday development workflows.
Many existing tools were cluttered with ads, required an account, uploaded data to a server, or only solved one very specific problem. I wanted to build a single place where developers could quickly find and use practical tools without unnecessary friction.
Today, CodingTool.dev includes 70+ free browser-based tools for developers, designers, QA engineers, and technical teams.
Some of the principles behind it:
⚡ Fast and focused tools for everyday technical tasks
🔒 Local processing whenever browser APIs make it possible
🚫 No signup or account required
🧰 Coding, conversion, testing, debugging, design, and productivity tools in one place
📱 Accessible from both desktop and mobile browsers
What started as a small personal project has gradually grown tool by tool, based on recurring problems I encountered while working and feedback from other developers.
CodingTool.dev is still actively evolving, and I’d really appreciate your feedback:
• Which tool is the most useful to you?
• What developer workflow is still missing?
• Is there anything that feels confusing, slow, or unnecessary?
Thanks for checking it out — I’ll be here throughout the launch to answer questions and hear your suggestions 🙌

A dark mode toggle would be really nice for those late-night coding sessions when the bright white background gets harsh on the eyes.

Honestly the no-signup thing is kind of a game changer, just opened it and used the JSON formatter in like two seconds. Running everything locally in the browser is a nice touch too.

Finally a dev toolkit that respects my time. Tried the JSON formatter and it was instant, no ads or upsells blocking the screen.
Really exciting to see CodingTool.dev launch! Free, Fast & Easy Developer Tools in One Place feels like a thoughtful approach. Congratulations, and best of luck today! 🚀
