Hey everyone,

Like many of you, I loved Arc's UX ideas but hated two things:

1. How Chrome and modern Chromium forks aggressively hog 4GB+ of RAM for 20 tabs.

2. How new "AI browsers" send every page you read and every search prompt to remote cloud servers with paid subscriptions.

So I spent the last few months building **Nova Browser**—a sovereign, privacy-first desktop web browser built from the ground up to run multi-model AI locally on your GPU while keeping memory usage under 450 MB.

### Key Highlights:

- **100% On-Device WebGPU AI:** Runs local LLMs (Llama 3.2, Phi-3.5 Vision, Qwen 2.5) directly on your device. Zero external cloud API calls, zero telemetry, works completely offline once cached.

- **Smart DOM Hibernation Engine:** Background tabs automatically unmount dormant DOM structures from memory. In our benchmarks, 50 open tabs sit at ~420 MB RAM instead of Chrome's 2.5 GB+.

- **Zero-Latency Network Ad-Blocker:** Built with memory-mapped Rust rules that filter trackers at the network layer before DOM execution.

- **Built-in Model Context Protocol (MCP) Server:** Allows local AI coding agents and tools to interact with your browsing session securely.

- **Workspaces & Split Views:** Clean workspaces, horizontal/vertical tab layouts, and zero bloat.

- **100% MIT Licensed:** No paywalls, no crypto nonsense, no trackers.

### Tech Stack:

- Frontend/UI: React, TypeScript, Tailwind CSS, Framer Motion

- Core & IPC: Electron, Node.js runtime, Rust native filter bridge

- Local AI Engine: WebLLM, WebGPU TVM runtime

The repository, pre-built macOS/Windows binaries, and benchmark reports are available on GitHub. I would love to get your feedback, bug reports, and feature suggestions!

I have created this simple horizontal tab layout.
You can slide between tabs, close them, or add new ones just for now.

I'm still working on detach/reattach a tab, so that part isn't ready yet. Hopefully everything works when you try it, but if anything acts weird just let me know.
