What is Liveswap?
Liveswap is a real-time face-swap service for Twitch and YouTube Live streamers that runs as an OBS browser source. Paste one URL into OBS Sources, pick an avatar, and go live. The swap adds under 100 milliseconds of latency at 1080p60 and works with NVENC hardware encoding on any RTX-class GPU.
How it works
Three steps from paste to live.
No install. No plugin. No driver. Works with your existing scene setup.
- 01
Paste the URL
Copy your signed browser-source URL from this page. Add it in OBS: Sources → + → Browser → 1920×1080.
- 02
Pick a face
Preview any avatar on your own webcam live. Bind swap-to-avatar to a Stream Deck key if you like.
- 03
Go live
Hit Start Streaming in OBS. Viewers see the swapped face. You see your own cam in the preview window.
Features
Built inside the streamer workflow
Every feature lives where you already work — OBS Sources, Stream Deck keys, scene switches. Nothing you have to learn from scratch.

Who Liveswap is for
Built for Twitch, not for a pitch deck.
The first wave of real-time face-swap tools was built for cinematic post-production. Expensive GPUs, long bake times, broadcast clients who paid in five figures. That's not a streamer's workflow.
Liveswap is the inversion. Server-side GPUs so your rig stays free for the game. One URL into OBS because that's already how every streamer adds a new source. A Stream Deck binding because you already own the device and you're going to hit the key anyway.
Pricing is the contract, not a claim. If we don't hit <100 ms at 1080p60 on the rig you say you have, the session is free — no credit card argument.

FAQ
FAQ
Do I need to install an OBS plugin?
No. Liveswap is a standard OBS browser source. You paste a URL into Sources → Add → Browser, set the width to 1920 and height to 1080, and you're done. No .zip, no admin rights, no driver.
How much latency does it add on my rig?
We measure 72 ms added at 1080p60 on a Ryzen 7 7700 + RTX 4070, 96 ms at 720p60 on an RTX 3060, and 140 ms worst case on 2019-era hardware. If your measured latency is higher than our published number for your rig tier, the session is free.
Is real-time face swap allowed on Twitch and YouTube?
Yes, as of the 2026-04 TOS review. Twitch community guidelines allow face alteration for entertainment; impersonation of specific real people without consent is not allowed and Liveswap avatars are all licensed original portraits. YouTube Live has a similar stance. Our /policy page keeps the current TOS citations.
Can I bind swap actions to my Stream Deck?
Yes, on the Creator and Partner plans. We expose a JSON endpoint that Stream Deck's System > Website or a custom plugin can call. Common bindings: SWAP FACE 01-03, NEXT AVATAR, RESET FACE, SCENE: CAM_ONLY.
Will it eat my GPU while I'm gaming?
No. The face swap runs on our servers. Your local machine is doing only OBS browser-source rendering, which costs a few percent of CPU. Your NVENC / AV1 encoder keeps the full budget for the game capture.
Can I upload my own face as an avatar?
On Partner. We license it, verify consent, and add it as a slot in your account. Turnaround is 72 hours. On Creator you pick from the 50+ built-in avatars, which refresh monthly.
Your OBS URL is one click away.
