Optional Section

📝 Notes

Closest existing entry is ZeroKit.dev (also DevTools, Completely Free). Acento differs in two ways:

1. Multilingual coverage — 9 languages (EN, ES, DE, FR, PT, NL, SV, DA, IT) vs English-only.
2. Includes financial/health calculators (mortgage, loan, BMI, TDEE) in addition to dev tools (JWT decoder, JSON formatter, base64, hash, regex tester, UUID).

🧠 Why this tool?

• 100% client-side — tokens, JSON, regex input never leave the browser
• No signup, no rate limits, no ads tracking cookies (cookieless analytics only)
• Cross-language URL routing with hreflang for international devs

📊 Evidence of Maintenance

Active site with regular content updates. The 432 content files were refreshed on 2026-05-04 across all 9 supported languages. New tools shipped monthly.
