NEXUS is a desktop browser built from scratch in Rust — an encrypted vault, a native
AI assistant you bring your own key to, and one-click Tor / WARP routing.
No company behind it, no data leaving your machine unless you send it.
No bundled search deals, no upsells, no "recommended by NEXUS" cards. Just the parts a browser is actually for.
Passwords are sealed with AES-256-GCM and an Argon2id-derived key. Your master password never leaves the device — there's no cloud to breach.
Route any tab through Tor or Cloudflare WARP with one click, or point NEXUS at a proxy you already trust. No extra client to configure.
Point it at Claude, GPT, Qwen, GLM, or any compatible endpoint. Prompts go straight from your machine to that API — never through a NEXUS server.
A shared, tuned connection pool and automatic tab suspension mean a background tab costs you almost nothing until you click back to it.
NEXUS polyfills chrome.runtime, so many Manifest-style extensions install and run with no rewrite needed.
Bookmarks come in through the standard Netscape HTML export, so moving from Chrome, Firefox, or Edge is one file — not an account migration.
An honest comparison — including where NEXUS is still catching up.

// NEXUS uses the OS's native WebView rather than shipping Chromium — that's most of the memory savings, and the occasional compatibility gap.
NEXUS isn't a company with a browser as its product. It's a Rust codebase anyone can read, fork, and build on. There's no telemetry to disable because none was ever wired in — and no roadmap driven by a term sheet, because there isn't one.
For everyday browsing — reading, search, video, most web apps — yes. NEXUS runs on your OS's native WebView instead of shipping Chromium, which is where the memory savings come from. A small number of very complex web apps may behave slightly differently than they do on Chromium.
You provide your own API endpoint, key, and model — Claude, GPT, Qwen, GLM, or anything else that speaks a compatible API. Requests go directly from your machine to that provider. NEXUS never sees your prompts and has no server in between.
Yes. NEXUS has a one-click toggle to route a tab through Tor or Cloudflare WARP, but it needs their official client running in the background — NEXUS doesn't bundle or replace either one.
No company — an individual maintainer plus whoever from the community wants to contribute. There's no roadmap dictated by investors, and no plan to monetize it later.
