Backends: rustfava runs the rustledger engine as an in-process WebAssembly component, so the wasmtime Python package ships as a dependency and the default backend works out of the box — no separate install needed.

To opt back into the legacy JSON-RPC engine (RUSTFAVA_RUSTLEDGER_BACKEND=jsonrpc), you must install the wasmtime CLI separately (it is not a Python dependency); the component backend does not need it:

curl https://wasmtime.dev/install.sh -sSf | bash

Other Installation Methods

Method	Command
Docker	docker run -p 5000:5000 -v /path/to/ledger:/data ghcr.io/rustledger/rustfava /data/main.beancount
PyPI	uv tool install rustfava (requires Python 3.13+; the wasmtime runtime is installed automatically)
Nix	nix run github:rustledger/rustfava#desktop

Quick Start

Desktop App

1. Download the app for your platform
2. Double-click to launch
3. Open your .beancount file

Command Line

rustfava ledger.beancount
# Then visit http://localhost:5000

What is this?

rustfava is a fork of Fava that replaces the Python beancount parser with rustledger, compiled to WebAssembly for faster parsing and processing.

The desktop app bundles everything into a native application using Tauri, so you get a fast, lightweight app with no dependencies.
