What are credits and how are they used?

Credits are the unit of consumption in Liveswap. Each minute of active Backstage session (face swap running) uses one credit. Credits reset monthly on your billing date.

Can I use Liveswap without a GPU?

Yes — that's the core benefit. All face swap processing happens in Liveswap's cloud infrastructure. Your local device only needs a browser and a webcam.

What makes Liveswap different from other face swap tools?

Most face swap tools require a powerful local GPU and complex setup. Liveswap runs entirely in the cloud, works on any device, and is ready in seconds with a single click.

How does Liveswap handle my privacy and data?

Your video stream is processed in real time and not stored unless you explicitly enable recording. All data is encrypted in transit and at rest.

What happens if I run out of credits?

Your Backstage sessions will pause until your credits renew at the start of the next billing cycle. You can also upgrade your plan at any time to get more credits immediately.

Is there a free plan I can try first?

Yes! The Free plan gives you 10 credits per month, 480p quality, and up to 10 minutes of recording — no credit card required.

Twitch Face Swap: The 2026 Streamer's Guide

The short answer: in 2026 you can stream on Twitch with a real-time AI face swap running as an OBS browser source. Liveswap generates a signed URL that you paste into OBS as a new Browser source; the browser source renders your webcam feed with the swapped face applied and sends that video into your OBS scene, which then gets encoded and sent to Twitch. Sub-100ms added latency on consumer hardware, no GPU upgrade required.

Why real-time face swap matters for streamers in 2026

Twitch's total face-on-camera time has been steadily increasing since 2022. Just Chatting remains the single largest category, and per-streamer watch time correlates strongly with camera uptime: streamers who keep the camera on retain audiences longer than those who hide behind game footage alone. That's the demand side.

The supply side of "camera on" has an obvious gatekeeping problem. Not every streamer wants to show their real face, every stream, forever. Traditional solutions — VTuber rigging, static PNG avatars, filters — either require significant setup time (rigging a Live2D model can take weeks) or lack expression fidelity (a static PNG can't react).

Real-time face swap sits between those two extremes. Setup is browser-based (under 5 minutes from cold start to first stream), and the swap inherits your real micro-expressions because it's operating on your actual webcam frames, not an animated skeleton.

The 2025 legal update from Twitch's community guidelines explicitly called out AI-generated or face-swapped content as allowed for original creative use, provided you're not impersonating a specific real person in a deceptive way. The guidelines were updated again in early 2026 to clarify that AI avatars using the streamer's own performance (voice, expressions, timing) are within the allowed creative-tool category. The short version: face swap is on-platform; impersonating a real named person to deceive viewers is not.

How Liveswap integrates with OBS

Liveswap runs as a Browser Source inside OBS — the same mechanism that powers chat overlays, alert boxes, and most visual plugins in the modern streamer stack. There's no OBS plugin to install; if your OBS version has browser-source support (OBS 29+), you have what you need.

The flow:

You go to liveswap.live/live and sign in (or start a trial session).
You pick a face avatar from the gallery — or upload your own source photo.
Liveswap generates a signed browser-source URL valid for your session.
You paste that URL into OBS: Sources → + → Browser → URL.
The browser source asks your browser for camera permission, which OBS handles by prompting through the browser source's embedded context.
The browser source now renders your webcam feed with the swapped face applied, at the resolution and frame rate you specified in OBS.
You drag the browser source into your scene; it composites with your game capture, chat overlay, and alerts like any other OBS source.

End-to-end added latency on consumer hardware (a mid-tier gaming PC from 2023 or newer) is under 100 milliseconds. That's within the latency envelope Twitch's live chat already tolerates — viewers won't detect a sync lag between your voice and your swapped face.

Step-by-step: your first OBS face-swap stream

Assumes: OBS 29+ installed, Twitch account with streaming configured, a webcam. Time to first live stream: ~5 minutes.

Step 1 — Get your Liveswap session URL

Open liveswap.live/live in your browser. If you're on the free trial, pick any avatar from the gallery (browse → preview → "Use this avatar"). On the Pro tier, you can upload a custom source face.

Click "Get OBS browser-source URL". The app generates a signed URL that expires with your session. Copy it.

Step 2 — Add the browser source in OBS

In OBS, click Sources → + → Browser.
Name it "Liveswap face" (anything you want).
URL: paste the signed URL from Step 1.
Width × Height: match your scene resolution. 1920×1080 for full-HD streaming, 1280×720 for 720p.
Custom frame rate: 30 FPS is safe; 60 FPS works if your upload bitrate supports it.
Shutdown source when not visible: optional but recommended — frees the webcam when you switch to a different scene.

Click OK. The browser source appears in your scene list.

Step 3 — Grant camera permission

The first time the browser source loads, it needs camera permission. OBS handles this by showing the browser source in a small preview window; accept the camera prompt there. The swapped feed will then render in your scene.

If you don't see a camera prompt:

Right-click the browser source → Refresh cache of current page to re-trigger.
Check OBS preferences → General → "Allow permissions for browser sources."

Step 4 — Test locally before going live

Always test the full stack locally before hitting "Start Streaming." In OBS, open Preview for your full scene. Check:

Does the swapped face track your real-time expressions?
Is there visible latency between your voice and mouth movement?
Does the face swap survive large head rotations (±30°)?

If lag is visible, drop the browser-source frame rate from 60 to 30. If the swap fails on large rotations, a different avatar from the gallery may be more rotation-robust.

Step 5 — Go live

Start Streaming in OBS. Twitch chat sees the swapped face. Your session runs until your Liveswap time pack expires (free: 15 minutes; paid: 1 hour or longer). A countdown in the browser source warns you 2 minutes before expiry.

Per-game integration notes

The face-swap layer sits independently of your game capture, so in principle any game works. Some categories have quirks worth knowing:

Just Chatting. The ideal category — the face is the focus, so a well-dialed swap pays off most here.
FPS games (Valorant, Apex, CS2). Fast head movements and stress reactions are where the swap's expression tracking is most tested. We recommend avatars with clean, front-facing source photos — strong jaw-line geometry tracks better during high-motion moments.
Survival / sandbox (Minecraft, Terraria, Sons of the Forest). Long sessions (2+ hours) are common; grab a 60-minute Liveswap pack and plan for a short swap reset between sessions.
Fighting games / co-op. Viewers notice facial expression more during hype moments. The swap picks this up naturally — if you pop off, so does your avatar's face.
IRL / outdoor streaming. The swap currently requires a stable indoor webcam angle. Outdoor / mobile streaming support is on the 2026 roadmap but not yet live.

Latency: the real numbers

We measure latency end-to-end — from a pixel leaving your webcam to the same pixel (with a swapped face applied) appearing in OBS's preview pane.

Hardware tier	Median latency	99th percentile
High-end (RTX 4070+ / M3 Pro+)	55 ms	90 ms
Mid-range (RTX 3060 / M2 / Ryzen 5 + iGPU)	75 ms	110 ms
Low-end (older laptop, integrated graphics)	110 ms	180 ms

All three tiers are within the latency envelope where viewers don't perceive desync between your voice and your swapped face. The bigger determinant of end-to-end quality is actually your Twitch encoder latency — set to "Low latency" or "Ultra low latency" in Twitch settings to keep the audience-side lag as small as possible.

Network conditions matter: Liveswap streams the face-swap inference from our cloud GPU pool. A stable 10 Mbps upstream is the floor; 25 Mbps+ is comfortable. If your ISP serves asymmetric fiber (1000 down / 50 up), you're fine. If you're on rural DSL, Liveswap will work but occasional frame drops are possible.

Streamlabs, OBS Studio, Streamer.bot — which to use?

Liveswap's browser source works with any OBS-family streaming tool that supports Browser sources. Notes per tool:

OBS Studio (recommended). The reference implementation. Fastest updates to the browser-source feature set. Free, open source.
Streamlabs Desktop. Based on OBS but with their own UI. Browser sources work identically. Some Streamlabs-specific plugins may conflict with heavy browser-source CPU load; monitor encoder drops during setup.
Streamer.bot. Not a streaming encoder itself — it's an automation layer. Liveswap is compatible with any automation triggered through Streamer.bot (e.g., trigger a face swap change based on a chat command).

For streamers just starting: OBS Studio is the safest recommendation. Once you're comfortable, Streamlabs adds UI polish if you want it.

Community reaction: how streams change with face swap

Data from 50 mid-tier streamers (10K–50K follower range) who adopted face swap for at least 4 weeks:

Median chat message rate: +18%. Viewers engage more when the avatar's facial expressions react to chat moments.
Median clip rate: +24%. The avatar reaction face during "oh my god" moments is inherently clip-worthy.
Subscriber-retention change: -2% to +8%. No significant direction — existing subscribers don't churn and don't gain at scale. The face swap is a growth tool, not a retention tool.
New-follower conversion (viewers → followers): +15%. This is the meaningful number. A novel face — consistent across streams — is a recognizable brand asset; new viewers remember who they just watched.

The qualitative feedback is also useful: viewers who know about the face swap find it charming; viewers who don't realize it's AI sometimes think the streamer has found an especially expressive filter. Both reactions are on-brand for the product.

Twitch TOS compatibility — what's explicitly allowed and what's not

Allowed:

Using a face-swap avatar as a consistent creative identity
Switching between multiple avatars within a stream
Interacting with chat / other streamers using your avatar
Monetizing the stream (subs, bits, donations) using your avatar
Playing ANY game (no game has banned face-swapped streams as of 2026-Q2)

Not allowed:

Impersonating a specific real person with intent to deceive. Don't pick "Elon Musk" as your avatar and claim to be Musk. The avatar as a creative tool is fine; using it for identity fraud is not.
Avatars that depict minors. Liveswap's gallery is 18+ avatars only; uploading a source photo of a minor violates our TOS regardless of Twitch's.
Avatars designed to harass specific real people. Don't target a specific real person's face for the purpose of ridiculing them.

The governing principle is intent. A creative tool used creatively is allowed; a creative tool used for harm is not.

Frequently asked questions

How do I face swap on Twitch?

Go to liveswap.live/live, pick an avatar from the gallery, copy the generated OBS browser-source URL, and paste it into OBS Studio as a new Browser source. The browser source renders your webcam with the face swap applied; add it to your scene and start streaming. Total setup time: under 5 minutes.

What's the best OBS face swap plugin?

Liveswap runs as an OBS Browser Source — no plugin needed. Browser sources are native to OBS 29+. If you're comparing to actual OBS plugins like FaceRig, OBS Studio's built-in Virtual Camera, or NVIDIA Broadcast, the browser-source approach is simpler (no installation) and hardware-agnostic (no NVIDIA RTX requirement).

Can I stream YouTube Live with a face filter?

Yes. Liveswap's browser source is agnostic to the streaming destination. Configure OBS to stream to YouTube Live (same encoder, different RTMP endpoint), and the face swap applies identically. We've tested Twitch, YouTube Live, Kick, and Trovo as of Q2 2026 — all work.

Is real-time face swap allowed on Twitch?

Yes, for creative use. Twitch's community guidelines allow AI avatars and face-swapped content for original creative expression. The restriction is on impersonation: don't use the face swap to pretend to be a specific named real person with intent to deceive viewers. Creative use is fully on-platform.

How much latency does a face swap add to an OBS stream?

End-to-end added latency (from your webcam frame to OBS preview) is under 100ms on mid-tier hardware. On high-end hardware it's under 60ms. Twitch's total stream latency (your voice to viewer's ear) is typically 3–15 seconds depending on settings; the face-swap contribution is negligible within that envelope.

Can I use Liveswap with Streamlabs Desktop?

Yes. Streamlabs Desktop is OBS-based and supports the same browser-source mechanism. Paste the Liveswap URL into a new Browser source within Streamlabs and it works identically.

Do I need an NVIDIA GPU?

No. Liveswap runs the face-swap inference in our cloud GPU pool. Your local machine just needs enough CPU to handle the browser source (any modern laptop suffices) and enough upload bandwidth to stream the encoded output to Twitch (10 Mbps+).

How much does Liveswap cost?

Free trial: 15 minutes per session, community avatars only. Paid sessions: $1.99 for 15-minute Quick Session, $4.99 for 60-minute Extended Session. Monthly subscription: $19/mo unlimited sessions + custom avatar uploads. No annual contract.
