FAQ
What is OpenSlides and who is it for?
OpenSlides is a free, open-source offline desktop app that turns code into polished slides with smooth Magic Move transitions, aimed at content creators, educators, developers, and anyone needing to present code beautifully without subscriptions or internet.
How do I install OpenSlides on macOS?
Download the appropriate Apple Silicon or Intel .dmg from the Releases page, drag OpenSlides to Applications, then right-click the app → Open to launch. If macOS blocks it, clear the quarantine flag with `xattr -dr com.apple.quarantine /Applications/OpenSlides.app` and try again.
What are the Linux installation options for OpenSlides?
OpenSlides provides .deb, .rpm, and AppImage packages. For Debian/Ubuntu install required runtime libraries (`libwebkit2gtk-4.1-0 libgtk-3-0 libscrypt0 libayatana-appindicator3-1 librsvg2-common`) then install the .deb. For Fedora/RHEL install `webkit2gtk4.1 gtk3 libappindicator-gtk3 librsvg2` then install the .rpm. AppImage requires FUSE; you can run with `--appimage-extract-and-run` or set `WEBKIT_DISABLE_DMABUF_RENDERER=1` on Wayland if needed.
Can I run OpenSlides from source, and what are the prerequisites?
Yes. You need Bun (or newer), a stable Rust toolchain with Cargo, and Tauri 2 platform dependencies. Clone the repo, run `bun install`, then `bun run tauri dev` to start the app, or `bun run dev` for a browser-only interface.
What technologies power OpenSlides?
The desktop shell is built with Tauri 2 and Rust. The UI uses Svelte 5 (runes), TypeScript, Vite 7, and Tailwind CSS 4, complemented by bits-ui, paneforge, @lucide/svelte, @tanstack/svelte-query, svelte-spa-router, persistent rune stores, Svelte transitions/springs, svelte-dnd-action, custom drag‑and‑drop, Shiki and shiki-magic-move for code rendering, and SQLite (via sqlx) for local storage.
