Image and video decision
Livesync
A technical user can build a limited, single-GPU self-hosted replacement (real-time swapping and streaming) using existing open-source projects, but reproducing Livesync's scale, polished UI, avatar ecosystem, and enterprise SLAs is non-trivial and likely not practical for a one-person effort.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Livesync alternatives, with the arithmetic →
What a replacement has to do
- Capture webcam video -> send frames to a server that runs a real-time face-swap model -> composite swapped face into output frames -> deliver encoded stream to user/RTMP (OBS/YouTube/Zoom).
What it still won’t have
- Polished multi-device UI and onboarding flows
- Large avatar library and curated personas
- Priority support, SLAs and enterprise integrations
- Production-grade queueing/scale for many concurrent streams
- Ethics/safety tooling and company-managed moderation
What remains hard
- Brand trust
Trusted by 25,000+ creators worldwide
- Infrastructure at scale
Utilizing multiple GPUs, it delivers top performance affordably, allowing scalable usage without costly hardware.

Runnable build prompt
Build a minimal self-hosted real-time face-swap streaming service using Node.js + Express for signaling, a lightweight React web client using WebRTC for webcam capture, and a GPU worker in Python (PyTorch) that integrates an open-source real-time face-swap repo (hacksider/Deep-Live-Cam) for inference. Core features in scope: 1) one-click avatar selection and mapping from a single reference image, 2) live webcam -> server -> GPU inference -> composited WebRTC/RTMP output to OBS/YouTube, 3) per-minute credit accounting and a simple admin UI to view usage, 4) containerized deployment (Docker) and a Terraform script to provision a single GPU instance. Out of scope: multi-tenant autoscaling, enterprise SLA, curated avatar marketplace, advanced moderation/ethics tooling. Include error handling for dropped frames, GPU OOMs, degraded inference, and end-to-end tests for signaling, inference, and encoding.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
