Reactive 2D avatars for your streams & videos.
Upload a few PNGs, pick your mic, and StreamSprite becomes a little avatar that talks, blinks and reacts — dropped straight into OBS. No rigging, no VTuber setup.
macOS 13+ · Apple Silicon & Intel · free updates
A whole VTuber-lite studio, minus the complexity.
Set up in minutes. No bones, no timelines, no rigging.
Mic-reactive mouth
Your character's mouth moves with your voice in real time. Voice-focus mode cuts background noise and keyboard clicks.
Your own art
Upload transparent PNG frames — you only need a closed and open mouth to start. It falls back gracefully for anything you skip.
Drops into OBS
A transparent, always-on-top overlay you capture as one clean window. Green-screen mode too, for any setup.
Custom states + hotkeys
Make your own states — name them, give them art, bind any key. Flip to BRB, rage, or coffee mid-stream.
Alive, not static
Idle float, breathing, bounce and a talking bob. Random blinking. Subtle motion that makes it feel like a little creature.
Optional head-tracking
Turn on the webcam and your avatar leans and looks with your head. Mic-only works perfectly without it.
A clean, native Mac app.
No clutter. Everything a page or two away.
Drop in transparent PNG frames with a live preview, test buttons and a checklist of what you've added.
From PNGs to on-stream in minutes.
Upload your frames
Drag in transparent PNGs — closed mouth, open mouth, and any extras you want.
Pick your mic
Grant mic access and watch the meter. Tune sensitivity and voice-focus to taste.
Go live in OBS
Start the overlay, position it, and capture the “StreamSprite Overlay” window. Talk.
On your stream in seconds.
No plugins. Capture one clean window and you're live.

Good questions.
What do I need to make a character?+
Transparent PNG frames of your character at the same canvas size. The bare minimum is a closed mouth and an open mouth; add small/medium/wide, blink and expressions for more life.
Does it work with OBS?+
Yes. Start the overlay, then add a Window Capture in OBS and pick the “StreamSprite Overlay” window. There's a transparent mode and a green-screen mode for chroma keying.
Do I need a webcam?+
No. Mic-only works great — your voice drives the mouth. Head-tracking with a webcam is an optional extra for leaning and looking.
Which Macs are supported?+
macOS 13 (Ventura) and later, on both Apple Silicon and Intel. It's a signed, notarized universal app.
Is it really one payment?+
Yes. $20 once, no subscription. Updates are free through the app's built-in updater.
Can I sell characters I make?+
A creator marketplace is on the way — you'll be able to list and sell your sprite packs. For now, you can export characters as a single file to share or back up.
