# Barc

> Barc is a free, open-source Arc browser alternative for macOS. Native WebKit, zero telemetry, no built-in AI, sleeping profiles and direct Arc import.

Barc is a personal, open-source web browser for macOS made by one developer who missed Arc and didn't want to learn a new browser. It recreates Arc's sidebar-first workflow on Apple's WebKit engine. Current version: 0.0.6 (released 28 October 2026). Requirements: macOS 14 or later, Apple Silicon or Intel.

## Key facts

- Rendering engine: WebKit, the engine built into macOS (no bundled Chromium).
- Native macOS app written in Swift 6; app bundle about 9.6 MB (local build).
- Telemetry: none. No usage analytics, no crash-report uploads, no update pings.
- No built-in AI assistant.
- Pages in inactive profiles hibernate after 1 minute (configurable: never, 1, 5 or 10 minutes).
- Background tabs above 2 GB of memory (default limit) sleep heaviest-first.
- Turning off generic element hiding saves about 18–19 MB per web process.
- Website passwords are stored in a local AES-256-GCM vault protected by one macOS Keychain item; no cloud sync.
- Imports from Arc: Spaces, nested folders, favourites, archives, history, bookmarks, passwords, cookies, local storage, addresses and search shortcuts.
- Imports passwords from Apple Passwords via CSV export.
- Known gaps in 0.0.6: passkeys not yet supported; builds are ad-hoc signed and not notarized; no automatic updates.
- Open source under Apache-2.0; a fork of Kylmora with full history and attribution.
