SimpMusic

A simple, open-source music app

SimpMusic is a GPL-3.0 music player that streams from YouTube Music and adds synced and translated lyrics, SponsorBlock skipping, and offline downloads. It runs on Android, including Android Auto, and ships desktop builds for Windows, macOS and Linux. Version 2.1.0 added Apple Music animated artwork with a Spotify Canvas fallback, delay and reverb audio effects, and custom playlist cover cropping. The app is free with no paid tier, ad-free inside the app, and distributed as APKs and desktop installers from GitHub releases plus a FOSS flavour for F-Droid.

Markdown

Tabula

Real-time collaboration for Markdown knowledge bases

Tabula opens a local Markdown folder as a live workspace in the browser, with no signup and no repository required. One encrypted room link lets other people and MCP-capable AI agents such as Claude or Codex edit the same files, leave comments, and see changes in real time. It follows Markdown links, backlinks, Wikilinks, and embeds, and searches both content and frontmatter metadata. The work is exported back out as portable Markdown files when the session is done.
