rustledger

rustledger is a complete rewrite of Beancount in Rust, designed as a drop-in replacement for the original Python implementation. It parses and processes Beancount ledger files up to 10x faster while maintaining 100% compatibility with existing .beancount files.

Key features:

• Drop-in replacement - Works with your existing Beancount files without any modifications. Same syntax, same semantics.
• 10x faster - Rust implementation dramatically speeds up parsing and queries, especially noticeable on large ledgers.
• Single binary - No Python runtime or dependencies required. Just download and run.
• Full toolchain - Includes rledger-check, rledger-format, rledger-query, rledger-report, and more.
• WebAssembly support - Try it directly in your browser at rustledger.github.io before installing.
• Works with Fava - Compatible with the Fava web interface for Beancount.

Perfect for developers and power users who love plain text accounting but want better performance from their tooling.
