Nacre

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
