Nacre is a free and open-source web browser for Windows, built on Chromium (Electron). Tor is on by default, with bridge support. Each workspace has its own cookies and storage. Ads and trackers are blocked locally, and phishing checks don't send the sites you visit anywhere. No account, no sync, no telemetry.

Nacre 1.0 is a beta: the installer is not signed yet and some protections are partial. If your safety depends on anonymity, use Tor Browser.

Features

  • Tor on by default, with obfs4 and Snowflake bridges
  • Separate cookies and storage for each workspace
  • Local ad and tracker blocking, with per-site controls
  • Local phishing warnings (visited sites are not sent anywhere)
  • Private tabs and clear site data on close
  • Bookmark import from Chrome, Edge, Brave, Vivaldi, Opera and Firefox
  • 20 interface languages
  • No account, no sync, no telemetry
