A Linux x86 web browser built on WebKitGTK and Rust, designed around sovereign identity instead of the traditional web's permissioned infrastructure. Identity, messaging, and relay operations are handled through Nostr, powered by the local rust_core_lib workspace crates.

Note: This project is a port to Rust from the original C99 project Sovereign_Browser. The Nostr functionality previously provided by the C library nostr_core_lib is now provided by the Rust workspace crates (nostr_core, nostr_relay, nostr_nips, nostr_signer, nostr_services).

Features

WebKitGTK-based browser shell with tabs, bookmarks, history, and search
Sovereign identity via Nostr keys (local + nsigner support)
Custom nostr:// and local:// URL schemes
Tor integration (tor_control + tor_scheme)
Built-in agent system: chat, conversations, skills, tools, MCP, LLM bridge, and an agent server
Site downloader and offline content embedding
FIPS / process / profile / settings management UIs

Architecture

The browser is organized into the following modules (see src/lib.rs):

Browser shell — tab_manager, menu, session, web_context, webkit_data
Nostr integration — nostr_bridge, nostr_inject, nostr_scheme, nostr_url, relay_fetch, key_store
Agent system — agent_loop, agent_chat, agent_conversations, agent_skills, agent_tools, agent_mcp, agent_server, agent_llm
Services — tor_control, net_services, site_downloader, settings_sync, fips_control

Building

Requirements: Rust (stable), GTK3, WebKitGTK 4.1, and the local rust_core_lib workspace at /home/user/lt/nostr_core_lib_rust.
