People who search “VTuber app” usually want one download that makes an anime face move on stream. The truth is quieter: a working Virtual YouTuber setup is a short stack of apps—tracking, sometimes a model editor, and a broadcast tool—not a single magic installer.
This page is the app-first guide. It tells you which VTuber app to open for which file, what belongs on the PC versus the phone, and how names like VTube Studio, Live2D, VSeeFace, PRISM, and OBS fit together. For a deeper product comparison, use best VTuber software. For the career path around the apps, read how to become a VTuber and what VTubing is.
What “VTuber app” actually means
A VTuber app is any program that helps you appear as a live avatar:
- Tracking app — reads your face or body and moves the model (VTube Studio, VSeeFace, Warudo, VNyan, PRISM’s avatar layer)
- Model app / editor — builds or edits the avatar (Live2D Cubism, Blender, VRoid)
- Broadcast app — encodes avatar + game + alerts to Twitch or YouTube (OBS Studio, PRISM Live Studio)
- Helper apps — PNGTuber tools, mobile face bridges, alert overlays
Search engines lump all of that under “VTuber app.” Your job is to pick the tracking app that matches your model, then a broadcast app. You only need Cubism or Blender if you are making the art yourself.
Best VTuber apps by job (quick picker)
| If you have… | Open this VTuber app first | Then broadcast with |
|---|---|---|
Live2D / .vtube.json model | VTube Studio | OBS Studio (or PRISM) |
| 3D VRM model | VSeeFace (free) or Warudo | OBS Studio |
| Still PNG frames | A PNGTuber app / plugin | OBS Studio |
| No model yet | Do not buy Cubism first — get a premade or commission | Practice mic + OBS |
Wrong picks are common: installing VSeeFace for Live2D, or buying Live2D Cubism thinking it is the live VTuber app. Cubism does not replace VTube Studio on stream.
VTube Studio: the default Live2D VTuber app
VTube Studio (VTS) is what most English-speaking indie Virtual YouTubers mean by “the VTuber app” when their avatar is 2D. It tracks a webcam or phone, plays hotkeys (jumps, tears, toggles), and outputs a transparent character for OBS.
VTS is a runtime. It does not draw the character. You load a finished Live2D model someone already rigged. That is why “I installed the VTuber app and I still have no avatar” is so common—the art is a separate purchase or commission.
Use VTube Studio when:
- Your file is Live2D-based
- You want hotkeys and expression toggles live
- You stream Just Chatting / games with a facecam-style crop
Skip it when your only file is a 3D VRM—use a 3D VTuber app instead.
VSeeFace and Warudo: 3D VTuber apps
VSeeFace is a free Windows app for VRM avatars. It is the usual first 3D VTuber app for indies who want dancing, room streams, or VR-adjacent movement without a big budget.
Warudo (and similar paid/show-oriented tools) add scenes, props, and effects when VSeeFace feels too bare for concert-style shows.
Rule: model type picks the app. Live2D → VTube Studio. VRM → VSeeFace / Warudo. They are not ranked “better”; they are different file pipelines. More detail sits in the software comparison.
Live2D Cubism is not your stream VTuber app
Live2D Cubism appears in every “VTuber app” search result because the format is named Live2D. Cubism is the editor for illustrators and riggers. Streamers who only bought a finished model never need to open Cubism to go live.
If you are an artist building avatars, Cubism is core. If you are a performer, your VTuber app is VTube Studio (or PRISM), not Cubism.
OBS Studio and PRISM: broadcast apps every VTuber uses
OBS Studio is free and remains the default way to mix avatar, game, alerts, and chat browser sources for Twitch or YouTube. The tracking VTuber app feeds OBS a window or transparent capture; OBS is what the platform receives.
PRISM Live Studio is an all-in-one some creators prefer: streaming features plus avatar support in one package. It can replace or reduce OBS for beginners who want fewer windows.
Neither OBS nor PRISM replaces a model. They are the broadcast half of the VTuber app stack.
Mobile VTuber apps and phone tracking
Phones show up in two ways:
- Face tracking bridge — an iPhone (often with VTube Studio’s companion flow) sends stabler face data to the desktop VTuber app
- Mobile-only experiments — lighter avatar apps for short vertical video; fine for TikTok tests, weak as a full Twitch/YouTube desk setup
For a serious Virtual YouTuber channel, treat the phone as a tracker, not as the whole studio. Desktop tracking + OBS still runs the show.
PNGTuber apps: the fastest first VTuber app
If you have no Live2D yet, a PNGTuber tool (image swap on voice or hotkey) is a valid first VTuber app. Many people debut that way while a custom model is in queue. You are still a VTuber; the app is just simpler. See VTubing for beginners and how to become a VTuber.
How to choose a VTuber app in five minutes
- What file do you own? Live2D, VRM, or PNG.
- Match the tracking app to that file (table above).
- Install OBS (or PRISM) and send a test scene to an unlisted/private stream.
- Fix audio first — a great VTuber app with a bad mic still loses chat.
- Upgrade later — Warudo, iPhone tracking, and Cubism are optional until the basics work.
Also confirm your model license allows monetized streams before you rely on any paid VTuber app for income. Model rights are covered in the models directory.
VTuber app vs “Virtual YouTuber software”
Marketers use VTuber app, VTuber software, and Virtual YouTuber program for the same stack. On BeTuber:

- VTuber Wikipedia — terms for creators, platforms, and culture
Common VTuber app mistakes
- Downloading Cubism expecting a moving avatar on Twitch tonight
- Installing VSeeFace for a Live2D folder (or VTS for a VRM-only file)
- Skipping OBS and wondering why the platform only sees a desktop wallpaper
- Buying three tracking apps before commissioning a licensed model
- Assuming a phone TikTok filter is the same as a full VTuber app pipeline
What to do next
Pick the tracking VTuber app that matches your file, pair it with OBS, and practice off-platform. Then read best VTuber software if you are comparing paid upgrades, what is a VTuber if you still need the role definition, and agencies vs indie if you are deciding whether an agency will even supply the model for you.
A VTuber app does not make you a Virtual YouTuber by itself. A model you can legally stream, a tracker that fits that model, and a broadcast tool you have tested once—that is the download list that actually matters.
