The Denpasoft app

What the app does

Download your games, keep your saves, and pick up where you left off. The everyday things, done properly.

• Download & install in one place

  Your downloads resume if the connection drops, and every file is checked before it installs. Pause one, come back later, and the app keeps track of what you own.

• Your whole library, organized

  Continue Playing puts your most recent game one click away. Playtime adds up across titles, and when a drive fills up you can install the next one to another drive.

• Encrypted cloud saves

  Your saves sync between your devices. They're encrypted on your own machine with a recovery phrase only you hold, so we can't read them. Keep the phrase safe; it's the only key.

• Sign in without a password

  Pair the app to your Denpasoft account from the web in one tap. You never type your password into the app, and you can unpair a device whenever you want.

• Already downloaded? Import it

  Already have the files on your disk? Point the app at them and it checks them and adds them to your library. No downloading what you already have.

• Optional Discord presence

  Let friends see what you're playing, if you want. It stays off until you turn it on, and you choose per title whether to show the real name or hide it.

Under the hood

The app is a small native core written in Rust (Tauri), with the same Astro and Cloudflare stack as the storefront for the interface. Here's what's inside, and why it matters for your library and your privacy.

• Tauri + Rust core

  A small, native core — not a heavy Electron shell. The sensitive work happens in Rust, not the web layer.

• AES-256-GCM encryption

  Your cloud saves are encrypted on your own machine before they ever leave it.

• A recovery phrase only you hold

  Your save key is derived from a recovery phrase that lives only with you — write it down once, and you're the only one who can unlock your saves. Your key, not ours.

• OS-backed credential vault

  Your login lives in the operating system's secure store, never in a plain file on disk.

• SHA-256 verified downloads

  Every file is checksum-verified before it installs, so what you run is exactly what we shipped.

• WebRTC streaming

  Your PC streams straight to your device — through your own machine, not a middleman.

On the roadmap

Your library shouldn't be locked in. We're building on open metadata, so your Denpasoft titles can show up and launch inside other launchers you already use. Here's what we're working toward.

• Researching

  Playnite

  List and launch your Denpasoft titles inside Playnite, next to your Steam, GOG, and Epic games.

• Researching

  Steam shortcuts

  Add titles to your Steam library and Big Picture so they launch from the same place as everything else.

• Researching

  Lutris (Linux)

  One-click install scripts so Linux players can grab a title straight from Lutris.

• Researching

  Linux app

  A native Linux build, with compatibility layers (Proton-GE) for Windows-only titles.

• Researching

  macOS app

  Mac support, with a compatibility layer for Windows titles where it's needed.

• Researching

  Open launcher metadata

  Documented deep links and per-title manifests so any launcher — not just these — can list and launch your library.

Everything here is exploratory. It's all still TBD — early research, not built, committed, or scheduled, and each would need real research and implementation before it's real. What ships, and when, may change. Want to nudge something up the list? Tell us in the Discord.
