FlashSeekBrowse – A Privacy-First macOS Browser

Why FlashSeekBrowse?

Blocks fingerprinting techniques, WebRTC IP leaks, and access to canvas & WebGL. Automatically upgrades to HTTPS where possible.

FlashSeekBrowse is written entirely in Swift using WKWebView, optimized for macOS. No cross-platform bloat — just clean native performance.

Built-in JavaScript console, source viewer, and support for Chrome-style extensions (planned).

No telemetry, no background sync, and no invasive UI. Just a browser that respects your choices.
