About Acento
Acento is a suite of free developer tools that run 100% in your browser. No accounts, no uploads, no tracking on the tools themselves.
How it works
Every tool uses native Web APIs — JSON.parse, crypto.subtle.digest, TextEncoder, crypto.randomUUID. When you format a JSON or compute a SHA-256 hash, the computation happens on your device. Your input never leaves your browser.
Languages
Available in English, Spanish, Portuguese, German, and French, with localized URLs and content for each language.
Technology
- Astro 5 for static HTML generation
- React 18 islands for interactive components
- Tailwind v4 for styling
- Cloudflare Pages for hosting
