About DevTool.group

DevTool.group is a collection of free developer tools built around one idea:a good tool should open instantly, do one job well, and respect your privacy.

How it works

Every tool on this site runs entirely in your browser. Nothing you type — timestamps, dates, data — is ever sent to a server, because there is no server. The pages are static HTML delivered from a global CDN, and all conversion logic executes locally on your device.

Principles

• Free forever. No paywalls, no premium tiers, no locked features.
• No sign-up. No accounts, no email capture, no newsletter pop-ups.
• Privacy-first. Client-side only. We don't track you and have nothing to sell.
• Fast. Zero-JS pages wherever possible; interactive islands only where needed.

The stack

Built with Astro and Tailwind CSS, hosted on Cloudflare Pages. Open source and MIT licensed.
