#lossless

Multithreaded PNG optimizer written in Rust

A YAML 1.2 parser and serialiser for Rust: zero unsafe, full serde integration, lossless CST editing, JSON Schema validation, 406/406 on the official test suite. Core of a six-crate ecosystem with a CLI, LSP, MCP server, WASM bindings, and a serde_yaml drop-in.

Lossless compression C library built for ultra-fast decode. Faster than LZ4 (40-75%+ on ARM64), at a better ratio. Official Rust, Python, Node.js, Go and WASM bindings. Write-once/read-many, with optional seekable archives for O(1) random access.

Power system compiler infrastructure

Python module to fetch Spotify track metadata and retrieve matching lossless audio through configurable Tidal, Qobuz, Deezer & Amazon Music providers.

Telegram bot that turns a song name into a lossless file in your library: resolves it on Spotify, searches Soulseek through slskd, ranks the copies and lets you hear them first. Chat delivery sends the track in Telegram instead. Docker-ready.
