Install

mnem ships a single mnem binary plus optional Python and HTTP daemons. Pick the source that matches your platform.

From Cargo (any platform with Rust toolchain)

cargo install --locked mnem-cli
mnem --version

Requires Rust 1.95+ (see rust-toolchain.toml).

From npm (Node.js users)

npm install -g mnem-cli
mnem --version

# or one-shot via npx
npx mnem-cli --version

Downloads the prebuilt native binary for your platform at install time. Node 18+ required. No Rust toolchain needed.

From PyPI (Python users)

pip install mnem-cli
mnem --version

The PyPI package ships the same mnem binary as a manylinux / macOS / Windows wheel.

From a release binary

Download the platform tarball from the latest GitHub release:

curl -L https://github.com/Uranid/mnem/releases/latest/download/mnem-linux-x86_64.tar.gz | tar xz
sudo mv mnem /usr/local/bin/
mnem --version

Replace linux-x86_64 with linux-aarch64 / macos-x86_64 / macos-aarch64 / windows-x86_64.zip as appropriate.

Per-OS package managers

After v0.2.0, mnem ships only via Cargo and PyPI. The Homebrew tap, AUR, Nix, winget, and scoop channels have been dropped in favour of a lean three-channel model (cargo / PyPI / npm). The Cargo channel supports bundled-embedder, bundled-embedder-cuda, bundled-embedder-directml feature flags.

# npm (Node 18+, no Rust toolchain needed)
npm install -g mnem-cli

# Cargo (any platform with Rust 1.95+)
cargo install --locked mnem-cli --features bundled-embedder

# or via cargo-binstall (faster, downloads prebuilt)
cargo binstall mnem-cli

# PyPI (Python users)
pip install mnem-cli

docker run --rm -p 9876:9876 ghcr.io/uranid/mnem:latest http serve

cargo build --release --target wasm32-unknown-unknown -p mnem-core

Verify

mnem --version
mnem doctor

mnem doctor probes embedder, store, and config - useful first command after install.
