Why we built this

Every developer has been there — you need to quickly format some JSON, decode a JWT, or check a colour contrast ratio, and you end up on a random site that makes you sign up, pastes ads everywhere, or — worse — uploads your data to a server you don't control.

tinybench.dev exists to fix that. Every tool runs client-side in your browser using JavaScript. Your data never leaves your machine. No accounts, no tracking, no nonsense.

Our principles

⚡

Instant

No server round-trips. Everything happens in milliseconds, right in your browser tab.

🔒

Private

Your code, keys, and data stay on your machine. We never see what you type.

🧹

Clean

No popups. No modals demanding your email. No dark patterns. Just the tool.
