About Us

ToolUniverse is a collection of free, browser-based developer utilities — currently 6 tools, including a JSON formatter and validator, Base64 encoder and decoder, JWT decoder, regex tester, and YAML toolkit. Every tool runs entirely in your browser: nothing you paste is uploaded, logged, or stored on a server.

Why this exists

Most developers reach for the same handful of small utilities dozens of times a week — formatting a JSON blob, decoding a JWT to check a claim, testing a regex before committing it, converting a value to or from Base64. Existing tools for these tasks are often cluttered with intrusive ads, require an account, or quietly upload your input to a server you have no visibility into. ToolUniverse exists to be the opposite: fast, free, no login, and transparent about the fact that your data never leaves your machine.

Who’s behind it

ToolUniverse is built and maintained by Rishabh Choksi. It’s an independent project, not a venture-funded product — the goal is a dependable set of tools that stays fast and gets out of your way, funded by unobtrusive advertising rather than subscriptions or your data.

How the tools are built

Every tool follows the same design: a plain-text input, an immediate action, and a copyable result — no multi-step wizards, no required sign-up, no watermarked output. Keyboard shortcuts (Ctrl/Cmd+Enter to run the primary action, Ctrl/Cmd+Shift+C to copy) work the same way across every tool, so once you’ve learned one, you know them all.

What’s next

ToolUniverse is actively growing. New tools are added regularly, each held to the same bar: genuinely useful, fast, private by default, and consistent with everything already on the site. If there’s a tool you’d like to see built, or feedback on an existing one, we’d like to hear it — see the Contact page.
