MRLess node

Rust node for MRLess, an experimental messenger for local and invite-based mesh networks. There is no central server: every device runs its own node and stores its own identity, messages, contacts, groups, and file cache.

Responsibilities

• UDP and mDNS discovery on the local network
• TCP peer links with flood/relay routing and hop limits
• WebSocket API for the UI
• Local storage and an outbox for retryable delivery
• Invite codes for peers outside the current LAN
• Native library and application shells for macOS, iOS, Android, and Windows

The companion SolidJS client lives in MRLess UI.

Quick start

cargo run --release -- --name Alice

For the normal desktop workflow, keep both repositories next to each other and run bun run app from the UI repository. It builds this node when necessary, then starts the UI and connects it to the local WebSocket endpoint.

Platform builds

The repository contains the native shells and build scripts for macOS, iOS, Android, and Windows. The full workflow is documented in the UI repository's build guide.

Examples:

./scripts/build-macos.sh
./scripts/build-ios.sh
./scripts/build-android.sh
./scripts/build-windows.sh

Platform builds require their native toolchains. Apple builds require Xcode; Android builds require the Android SDK and NDK.

Status

Personal experimental project. The wire protocol is currently version 3 and the protocol, storage format, and platform packaging may change.
