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
