Meduza Music
Ultra-low memory, zero-telemetry native YouTube Music client engineered in Rust & Kotlin Multiplatform.
Modern desktop streaming clients (Electron-based) routinely consume 500MB+ of RAM just to stream compressed audio. Meduza was engineered from scratch in Rust and Kotlin Multiplatform to deliver an audiophile-grade, lightning-fast streaming interface with an absolute memory ceiling of 35MB.
Architecture
Meduza splits responsibilities between a headless native Rust audio daemon (built with Rodio, Symphonia decoders, and Tokio async runtime) and an ultra-light Kotlin Compose Multiplatform GUI. Inter-process communication operates via zero-copy shared memory and fast binary protocols, ensuring 120 FPS buttery UI render loops without ever interrupting audio decoding threads.
Mainstream music clients are heavy Chromium shells that consume excessive battery, collect user tracking telemetry, and introduce noticeable UI and buffer latency. Users on resource-constrained development machines or Linux laptops suffer degraded battery life and thermal throttling.
Key Decisions
Bypassed standard web/CEF audio pipelines in favor of direct ALSA, PipeWire, and CoreAudio drivers through Rust.
Impact: Reduced end-to-end audio buffer latency to 8.4ms with zero frame drops during heavy CPU load.
Cached decoded audio chunks directly on NVMe/SSD using memory-mapped files (`memmap2`) instead of SQLite blobs.
Impact: Instantaneous track scrubbing and seeking without memory reallocation spikes.
All YouTube metadata queries are proxied and cleansed locally; zero outbound analytics or fingerprinting.
Impact: Guaranteed user privacy and completely offline metadata playback capabilities.
