Conclave is built entirely from scratch in Rust. No Chromium. No telemetry. No data selling. Just a browser that works for you.
Built from scratch in Rust. Windows first, currently in development.
Most browsers make money by watching what you do. Conclave makes a different promise: your activity is yours alone.
Conclave
Every component, built in-house
From the network stack to the rendering engine, Conclave is engineered top to bottom. No black boxes, no borrowed engines.
A purpose-built parser and layout engine written in Rust, designed for correctness, speed, and predictable memory behavior.
A scripting layer engineered for safety and isolation, keeping page logic sandboxed away from your system.
A custom TLS 1.3 implementation with HSTS, no reliance on third-party crypto crates, and full control over every byte on the wire.
A hand-written GPU compositor that paints pages with hardware acceleration and zero external graphics dependencies.
Per-site partitioned cookie jars built on CHIPS, so cross-site trackers cannot follow you between domains.
Built-in protections that warn you about dangerous sites without shipping your browsing history to a third party.
// Custom TLS 1.3 handshake, no third-party crypto crates pub fn establish_secure(host: &str) -> Result<Connection> { let policy = Policy::strict() .require_hsts(true) .min_version(Tls::V1_3) .block_telemetry(true); let conn = Connection::handshake(host, &policy)?; // No analytics. No reporting. No exceptions. Ok(conn) }
The same in-house engineering that protects your privacy is what makes Conclave fast.
Frequently used code compiles straight to native machine code, so scripts run at full speed instead of being interpreted line by line.
When the page changes, Conclave repaints only the region that moved and reuses the rest from cache, instead of redrawing everything.
Page loading and scripts run on a separate thread from the interface, so the window keeps responding even while a heavy page is working.
Finished frames are composited on the graphics card, for smooth scrolling and fluid animation.
A clear look at how Conclave compares to the browsers most people use every day.

Conclave is in early access and growing fast. Here is an honest look at what is shipped, in progress, and planned.
Conclave is engineered top to bottom in-house: 412,000+ lines of Rust across 45 purpose-built crates, with zero trackers shipped. No Chromium fork, no borrowed engine, no advertiser sitting between you and the web. Follow development on X as the first build takes shape.
Conclave is funded by people who believe browsing should not come at the cost of your privacy. Every contribution keeps development independent.
Conclave is independent and privacy-first: no ads, no trackers, no data deals. It is built by people who want a browser that does not monetize its users, and backing from companies and individuals is what keeps development focused and free of those incentives.
