VTubing on Linux
Linux is not an afterthought here, it is the main platform: this is built and tested on it every day, on Arch and on Debian. Hologramu runs natively, without Wine, and registers itself through V4L2 — OBS simply sees it as a webcam.
Hologramu
Your light, your stage.
The 3D VTuber app that sees more than your face: pick up your phone and your avatar picks up theirs. Tracking is completely free — on Linux and Windows.
Not released yet — Hologramu is still in development.
- Tracking completely free
- VRM & Minecraft skins
- Linux-first
- No account, no subscription
What only Hologramu does
All captured from the running app — nothing staged.
01
Real objects, real hands
Pick up your phone and your avatar does too. Hologramu spots a phone, mug, bottle or controller in the camera image and puts the matching model in your avatar's hand — the fingers wrap around it instead of passing through. The keyboard and mouse on their desk move with your real keystrokes and mouse movements.
Free, with any webcam. Your own 3D models can be picked up too.
Phone picked up — the avatar does the same
02
Real depth from multiple cameras
A single webcam only sees a flat picture — stretch your arm straight towards it and it cannot tell how far. Add a second camera at the side and Hologramu merges both views into a real 3D pose: your avatar reaches exactly as far forward as you do.
Free. Cameras are detected automatically, and calibration measures where they stand.
Arm stretched forward — with two cameras the depth is right
03
A webcam and a microphone to the system
Hologramu registers itself as a camera and as a microphone. In OBS, Discord, Zoom or the browser you simply pick “Hologramu” — your avatar's picture, plus your changed voice and soundboard. No window capture, no green screen, no fiddling with audio cables. When no scene is open, the camera shows a picture or video of your choice.
Both built in on Linux. On Windows, OBS captures the recording window with a transparent background, and the audio goes through a virtual audio cable such as VB-Cable.

04 Creator
Animation Studio
Record movements live or build them bone by bone in the keyframe editor. Only what you keyed is locked — everything else keeps following your tracking. So your avatar waves at the press of a key while face and head stay live. Props appear, move and vanish with the animation.

05
A real 3D stage
Your avatar does not stand in front of a picture but inside a room: lights with shadows, particles that collide with them, wind, objects of your own and several cameras with image filters — switchable by hotkey mid-stream.
All of it in the free version, without a watermark.

Why Hologramu
What else speaks for Hologramu — all of it in the free version.
Tracking without a paywall
Face, hands, full body, multiple cameras, calibration: all free and without a watermark. An ordinary webcam is enough — no iPhone, no trackers.
Native on Linux
Developed and tested on Linux, on Arch and Debian — no Wine, no workarounds. Windows gets the same app.
Featherweight
Written in Rust and built to stay small. Your GPU and CPU stay free for the game you are actually streaming.
VRM & Minecraft
Any VRM model with expressions, costumes and physics for hair, ears and tail — or your Minecraft skin, fetched by player name.
Hair that plays along
Hair, ears and tails swing on their own, wind blows through them, accessories swing with them — and the idle motion keeps you alive between takes.
Fits your setup
Send and receive VMC: keep using tracking from VSeeFace or Warudo, or send the finished pose on to other apps.

The free version is a real VTuber app
If you are just starting out with VTubing, Free really is all you need. Load an avatar, track — even with several cameras —, build your stage and go live as a webcam in Discord or OBS. No watermark, no time limit, no account.
Want to build your own animations? Get Creator with the Animation Studio. The Streamer Edition comes later — with Twitch interactions that let your chat play along.
What is Hologramu?
Hologramu is VTuber software: it moves your head, face and hands from a webcam onto a 3D avatar and hands that avatar to OBS, Discord or anything else as a virtual camera. No green screen, no tracking hardware, no account.
3D VTubing with VRM
Your avatar is a real 3D model in the VRM format: blendshapes for the face, physics for hair, ears and tail, swappable costumes and cameras you can place anywhere. Prefer something pixelated? Load a Minecraft skin instead.
Start for free
The free version is a complete app, not a demo: load an avatar, track face, hands and body, build a stage, go live. An ordinary webcam is enough — and an existing setup carries over from VSeeFace or Warudo via VMC.
Frequently asked questions
When is Hologramu released?
It isn't out yet — Hologramu is still in development and there's no download link on this page for that reason. Linux (tested on Arch and Debian) and Windows 10/11 land first.
Is the free version any good?
Yes — it is a complete VTuber app, not a trial. Complete tracking including full body and multiple cameras, interactive objects, virtual camera and microphone, the scene editor, voice and soundboard all run without a watermark.
What does it cost?
The app costs nothing, forever. On top there are two optional Steam DLCs as one-time purchases: Creator with the Animation Studio (price at launch) and, later, the Streamer Edition with Twitch interactions. There are no subscriptions anywhere.
What is the watermark exactly?
If you use a DLC feature in the free version, a tiled “Hologramu” appears over the picture. Nothing is switched off and nothing expires — you can try it for as long as you like. Buying removes it for good. Tracking never triggers a watermark.
Does it really run on Linux?
Linux is the main platform. Hologramu is developed and tested on Linux daily, and the Linux build ships at the same time as Windows.
Does it work with OBS?
Yes. On Linux, Hologramu registers as a camera via v4l2loopback — in OBS, Discord, Zoom or the browser you simply pick it as your webcam, and the virtual microphone along with it. On Windows, OBS captures the recording window with a transparent background.
Why multiple cameras?
One camera only sees you from the front and has to guess how far something is towards it or away from it — to it, an arm stretched forward looks almost like a bent one. A second camera at the side provides exactly that depth, and Hologramu merges both views. One camera is still perfectly fine; the second is an extra.
Do I need special hardware?
No. Any ordinary webcam will do — tracking runs on MediaPipe. A second webcam improves depth but is optional. If you already have a setup, you can also drive Hologramu from VSeeFace or Warudo via VMC.
Is there any VTuber software for Linux?
That is exactly why Hologramu exists. Most VTubing programs are Windows-only, or run on Linux through Wine at best — Hologramu is built natively for Linux and developed there. Coming from VSeeFace or Warudo, you can keep your setup over VMC.
Which avatars are supported?
VRM, the standard format for VTuber avatars, and Minecraft skins — either fetched by username or uploaded as a file.
Is it actually lightweight?
That's the point of the whole project. Hologramu is written in Rust and built to stay out of the way, so the machine's headroom goes to your game and your encoder instead of your avatar.
