Why Nivio

Built for games that ship every week

F95Zone titles update constantly. Most managers re-download the entire game each time — we treat builds like a software repo. Push only what changed; cache the rest.

Smart delta patches
We chunk every build with content-defined hashing (xxh128) and ship only the differences. Typical 5 GB game → 200 MB update.
Auto-fetch from F95Zone
Nivio's parser watches threads in real-time. New version drops? Your client knows in minutes — no more refreshing forum tabs.
Per-build version history
Every release is preserved. Roll back to a known-good build with one click when an update breaks your save.
~6 MB client, not 200
Built on Tauri (Rust + native webview), so we skip the bundled Chromium most launchers ship. The Windows installer is 6 MB; macOS ~10 MB. Boot is instant and idle RAM stays under 100 MB.
How it works

From "new version posted" to "playing" in three steps

One desktop app, one library. Pick a game, click install — Nivio handles the rest.

1

Install the client

One small download, ~30 MB. Sets up your library folder and connects to the F95Zone update feed.

2

Add games

Browse the catalogue or paste an F95 thread URL. The first install grabs the full build from our CDN.

3

Updates apply themselves

When a new version lands, the client fetches only the changed chunks and patches your local files in place. Nothing redownloaded.

FAQ

Frequently asked

Is this affiliated with F95Zone?

No — Nivio is an independent project. We mirror publicly available builds linked in F95Zone threads and cache them as delta patches. All credit and traffic for game discovery still belongs to the original developers and the F95Zone community.

How are delta patches built?

Every build is split into content-defined chunks (4 MB target, identified by xxh128 hash). Two builds share most chunks, so an update is just the list of new ones plus a manifest. The client verifies, downloads, and applies in place.

What about adult content?

F95Zone's catalogue is 18+ by definition. Nivio is for adults. The client gates everything behind a one-time confirmation; the catalogue is never shown on this landing page. If you're under 18, this isn't for you.

Mac & Linux?

Windows is the priority during beta because most F95 games are Windows-only. Native macOS & Linux builds (unsigned) are next on the roadmap.

Will this stay free?

The client is and will remain free. Bandwidth costs scale with usage — if Nivio outgrows what we can host, we'll add an optional supporter tier for power users. The default plan stays free forever.

Why is the download so small (~6 MB)?

Nivio's client is built with Tauri (Rust + the OS's native webview), not Electron. That means we don't ship a copy of Chromium with every install — we use the WebView2 runtime that already ships with Windows and the WKWebView that ships with macOS. Result: a 6 MB Windows installer and a ~10 MB macOS bundle, instead of the usual 100–200 MB you'd get from an Electron-based launcher. RAM and CPU footprint are smaller too, and updates to the client itself are fast.

Stop wasting bandwidth on full reinstalls.
