Works on webcam, video, or a photo
Use a live webcam feed, load an uploaded video file, or run detection on a single still photo — same pipeline either way, on desktop or mobile.
Nothing ever uploaded
All detection runs locally via WebAssembly computer vision — no camera frame, video, or photo leaves your device.
Export what you track
Record tracked video in WebM or MP4 up to 1440p, export a PNG frame sequence, or pull frame-by-frame coordinate data as CSV.
Streams live to TouchDesigner
Broadcast blob IDs, coordinates, bounding boxes, and velocity as live JSON telemetry over OSC/WebSocket to TouchDesigner, Max/MSP, or Ableton.
Audio-reactive visuals
Sync any visual style to the loaded video's own audio track or a live microphone input via real-time FFT frequency modulation.
Touch-optimized mobile UI
A bottom-sheet quick-style bar, swipe-between-modes gestures, and full mobile camera support — not a shrunk-down desktop layout.
What is Vis Exo?
A free, web-based computer vision tool inspired by TouchDesigner's Blob Track TOP. It runs real-time blob, motion, face, object, pose, person, and hand tracking with 35 visual styles, entirely in your browser.
Is it actually free?
Yes — every tracking mode, visual style, and export option is free with no signup, watermark, or usage limit.
Do I need to install anything?
No. It runs entirely in your browser via WebAssembly computer vision — open the page and start tracking immediately, on desktop or mobile.
Is any video or webcam footage uploaded to a server?
No. Every tracking mode runs locally on-device — no camera frame, video, or photo ever leaves your browser, and there's no account to send it to in the first place.
Can I export the tracked video?
Yes — record in WebM (VP9/VP8) or MP4 (H.264) up to 1440p, export a PNG frame sequence, or download frame-by-frame coordinate telemetry as CSV. See the tracking data export guide for details.
Does it work with TouchDesigner?
Yes — enable the built-in OSC / WebSocket panel to stream live JSON tracking telemetry straight into TouchDesigner, Max/MSP, or Ableton. See the TouchDesigner alternative guide.
What is the blob tracking effect?
It's the look of boxes, labels and connecting lines following shapes around a video — made by detecting blobs in each frame and tracking them over time. Vis Exo generates it live on a webcam or any video, free.
Is there a free blob tracker online?
Yes — Vis Exo is a free blob tracker that runs in your browser with no install. Load a video or use your webcam, then export the result as MP4 or the tracking data as CSV.
Can I make face, body or hand tracking effects too?
Yes — the same app tracks faces, whole bodies, hands and anything that moves, with the same styles and export options. See the face tracking effect, body tracking effect and hand tracking effect guides.
Can I color grade video or use my own LUT?
Yes — pick from 33 built-in cinematic LUTs or import your own .cube file, then fine-tune with Lift, Gamma, Gain, Offset, temperature, tint and vibrance. See the color grading guide.
Can I change effects at specific times in a video?
Yes — the Keyframe editor in the Clip Editor animates nearly 40 settings along a video's timeline, or switches an effect on for a set time range. See the keyframes guide.
