What Is It
An online live-stream sticker watermark tool that brings anti-piracy, anti-recording and forensic tracing to public-facing live streams.
Everything runs in the browser — no local software to install: lay out your watermark stickers in the web editor, copy the render URL, and add a single browser source in OBS (or your streaming companion app). The watermark is overlaid on your stream instantly — with transparent background support, truly plug-and-play.
From that moment, every frame of your stream carries your mark. Screen recordings, screenshots, re-uploads — every copy that leaves your stream carries it too.
Why Live Streams Need Watermark Stickers
Pirated streams and re-uploaded recordings are problems every public streamer eventually faces:
- Courses, coaching sessions and community content get screen-recorded and resold;
- Stream highlights get re-uploaded to other platforms, siphoning off your traffic;
- Pirates impersonate you on live streams, diverting your fans and damaging your reputation.
Ex-post enforcement is expensive; ex-ante deterrence is the highest-ROI defense. A watermark permanently on screen means every recording, every re-upload carries traceable evidence — most would-be pirates will think twice before hitting the record button.
To be clear (stated on the product page as well): watermarks cannot 100% prevent piracy. Their value is deterrence, tracing and evidence — dramatically raising the cost of piracy and leaving verifiable evidence when disputes arise.
Core Features
Dynamic Forensic Variables: Not Just a Watermark — a Traceability Chain
Insert dynamic variables into stickers:
{time}— real-time timestamp{date}— current date{session}— session number{channel}— channel code{random}— random identifier
Combine several variables in one watermark to build a complete traceability chain: the pirated footage itself carries “which session, which channel, what time”. Distribute a unique channel code per recipient and the leak source is one lookup away.
21 Behavior Effects, Including AI-Repair-Resistant Drift
A static watermark dies to one screenshot crop — so the stickers move:
- Scrolling, jumping, breathing, blinking, rotating, shaking, pulsing, ghosting and more — 21 behavior effects;
- Three independent overlay channels, no interference;
- Built-in scene presets, one-click apply;
- Trajectory drift moves the watermark position over time — AI-based repair or cropping against it costs far more effort.
Text + Image Stickers, Pixel-Accurate Layout
- Free text stickers (CJK and Latin fonts) and image stickers (logos, QR codes);
- Drag, scale and rotate from any corner, positioned to the pixel;
- Multi-sticker compositions; one configuration reusable across multiple stream projects.
Seamless Green-Screen Blending
Green-screen / solid-background mode is supported. Window captures and assets without alpha channels blend seamlessly into your stream — no extra asset processing needed.
Free-Form Canvas, up to 4K
- Canvas up to 4K, plus portrait and arbitrary sizes;
- One-click tile across the full frame, or pin to all four corners;
- Landscape streams, portrait e-commerce, course recordings — one editor covers them all.

FAQ
Q: Do I need to install anything? No. Everything runs in the browser; OBS only needs one browser source.
Q: Which streaming software is supported? OBS Studio and platform streaming companions (Douyin / Kuaishou / WeChat Channels, etc.) — anything with browser-source support.
Q: Can the watermark be cropped out? With trajectory drift and multi-channel effects, simple crops rarely get everything. That said — as stated above — no watermark can guarantee 100% protection; the value lies in raising piracy costs and preserving forensic evidence.
Q: Will it slow down my stream? The watermark renders as a browser source and doesn’t compete with game/camera capture for encoding resources. Under normal configurations the impact on stream performance is negligible.
