Unofficial mirror · offline-first mesh

bitchat

App stores can be blocked. Phones talking over Bluetooth are much harder to silence. This mirror keeps bitchat’s Android APKs reachable when upstream is throttled, taken down, or censored.

Install & verify

Sideload

  1. Allow your browser to install apps: Settings → Apps → Special app access → Install unknown apps.
  2. Install the APK, then open bitchat.
  3. Grant Nearby devices / Bluetooth. Location may be requested — that is an Android BLE scanning rule, not GPS tracking by the app.

Verify

  1. Copy the SHA-256 shown next to the file (or open checksums).
  2. Run sha256sum your.apk and compare.
  3. Source for each build is the linked upstream commit. bitchat is GPLv3 — you can inspect and rebuild it.

How this works

Upstream APKs are mirrored to Cloudflare R2 on a schedule. This site is static HTML on Vercel — the UI loads here; APKs download from R2.
