Clip-based online tools avoid the hardware, but you upload, wait and download — nothing happens live. ## The cloud approach [LiveFaceSwapVideo](https://livefaceswap.video/) moves the heavy work to the cloud: - You pick one reference portrait (yours, or one you have permission to use) and open your webcam. - Frames travel over an encrypted WebRTC connection to realtime models (Lucy 2.5 or XMAX 2.0). - The transformed stream comes back to the browser at interactive latency; the feed is not recorded or stored. Besides face swap there is Live Try-On (change outfits) and Live Restyle (anime or illustration looks). ## Getting it into streaming and meeting apps The browser studio is enough to try it. For streaming or calls, the free Windows 11 desktop app installs a [face swap virtual camera for OBS and Zoom](https://livefaceswap.video/desktop) — it also shows up in Google Meet, Teams, Discord and other apps that let you choose a camera. macOS is coming soon. ## Cost 100 free credits on signup; Lucy uses 20 credits/s and XMAX 3 credits/s, billed only after the AI video appears. Plans start at $14.90/month. ## Ground rules Consent first: your own face or an authorized portrait only. No public figures, no minors. More: https://livefaceswap.video/ --- ## Summary LiveFaceSwapVideo enables real-time face swapping on ordinary laptops by processing video frames through cloud-based AI models via encrypted WebRTC connection, with results streamed back to the browser at interactive latency. The service offers a free browser tool and a Windows desktop app for integration with streaming and meeting platforms, with pricing starting at $14.90/month after free trial credits. ## Themes - cloud-based face swap - accessibility without GPU - real-time video processing - consent and ethics ## Key takeaways - LiveFaceSwapVideo processes face swap in real-time by sending webcam frames over encrypted WebRTC to cloud models and returning transformed video at interactive latency. - The service offers three distinct features: face swap, Live Try-On for outfit changes, and Live Restyle for anime or illustration effects. - A free Windows 11 desktop app creates a virtual camera compatible with OBS, Zoom, Google Meet, Teams, and Discord. - Lucy 2.5 model costs 20 credits per second while XMAX 2.0 costs 3 credits per second, with 100 free credits on signup and plans starting at $14.90 per month. - The service requires consent: users may only swap their own face or an authorized portrait, prohibiting use with public figures or minors. ## Insights - The service shifts computational burden from user hardware to cloud infrastructure, making real-time face swap accessible to ordinary laptops. - Integration with existing streaming and meeting platforms through a virtual camera driver significantly expands practical use cases beyond the browser studio. - The pricing model charges only for processed output rather than input frames, aligning costs with actual service consumption. ## Open questions / gaps - What is the typical latency experienced by users, and how does it compare to local GPU-based solutions? - What specific technical measures ensure the encrypted WebRTC connection and prevent frame storage or recording?
