# Bibel-Vergleich Pro

> Free web app to compare 1000+ Bible translations side-by-side. Includes Luther, Elberfelder, Schlachter, KJV, NIV, ESV, BSB, WEB, NET, ASV and many more. Notes, reading plans, highlights, offline mode, verse-as-image sharing — no signup, no ads, no tracking beyond optional anonymous analytics.

Bibel-Vergleich Pro is a static vanilla-JS PWA (Progressive Web App) running entirely in the browser. All Bible data is fetched from the open bible.helloao.org API. User data (notes, highlights, plans, bookmarks) stays in the local browser via IndexedDB.

## Why it exists

YouVersion is excellent but cloud-tied and account-required. SwordSearcher is desktop-only. BibleHub is web but cluttered and ad-heavy. Bibel-Vergleich Pro is the minimal contrast: open the browser, click a translation, read or compare. No account, no install (optional PWA), no ads, no tracking unless you opt in to anonymous Umami analytics.

## What it is NOT

- Not a study Bible with built-in commentary (commentary is linked via translation modal, lazy-loaded)
- Not a cloud-sync service — all user data is local-only by design
- Not a paid product — donations welcome via lern-digital.de but no upsell
- Not affiliated with any specific church or denomination — translations span Catholic, Protestant, Orthodox, evangelical, scholarly editions
