Why SpotLight?

I love Spotify, but I don't love how a background music player can easily eat up a gigabyte of RAM and unnecessarily drain my laptop's battery. The official desktop app is built on web technologies (CEF/Electron), which is great for cross-platform development, but terrible for resource efficiency.

I wanted something native, fast, and incredibly light. No embedded web browsers, no Javascript engines. Just pure Rust.

The primary goal of this app is not to have the most features or the most beautiful UI, but rather to function in the most lightweight and resource-efficient way possible.

The Numbers Speak for Themselves:

Because SpotLight is built with egui, the UI completely goes to sleep when you aren't interacting with it. No wasted GPU or CPU cycles.

Features

• Native Playback: Full audio playback powered by librespot (Spotify Premium required).
• Perfect Synced Lyrics: Real-time, time-synced lyrics that automatically scroll exactly like the official app (powered by LRCLIB).
• Custom Themes: Unhappy with the default green? Pick any accent color you want straight from the settings.
• Native Media Controls: Full integration with Windows System Media Transport Controls (SMTC) and MPRIS. Play, pause, or skip tracks right from your keyboard.
• Privacy First: Your Spotify credentials and API tokens are never sent to a third-party server. Everything is encrypted and safely stored in your native Credential Manager.

Getting Started

Since SpotLight relies on Spotify's Web API and playback infrastructure, you need to provide your own Spotify Developer credentials. Don't worry, it only takes a minute.

1. Create a Spotify App

1. Go to the Spotify Developer Dashboard.
2. Log in and click "Create App".
3. Name it SpotLight (or whatever you prefer) and set the description.
4. Crucial Step: Set the Redirect URI to exactly http://127.0.0.1:8888/callback.
5. Check the Developer Terms of Service and hit Save.
6. Open the app settings to view your Client ID and Client Secret.

2. Run SpotLight

You can download the latest standalone executable from the Releases page, or compile it from source:

cargo run --release

On first launch, SpotLight will ask you for the Client ID and Client Secret you just generated. Paste them in, click "Login", and authorize the app in your browser. You're good to go!

Tech Stack

This wouldn't be possible without the incredible Rust open-source ecosystem:

• egui: The immediate mode GUI library that makes this app so snappy.
• librespot: The open-source Spotify client library handling the heavy lifting of audio playback.
• tokio: For handling asynchronous API requests smoothly.
• keyring: To ensure your API secrets are stored securely in the OS vault.
