Nano FaceSwap Pro
The best diffusion-based face swap for photos and videos — running 100% locally on your GPU. Try it free online, no sign-up fees.
A private, offline alternative to Roop, FaceFusion, Rope, Reactor, Deep-Live-Cam, DeepSwap, Akool, and HeyGen — built on the latest diffusion research (InstantID, PuLID, IP-Adapter FaceID, PhotoMaker, InsightFace).
Why a diffusion face swap is different
Most popular open-source face swap tools — Roop, FaceFusion, Rope, Reactor, Deep-Live-Cam — share the same underlying GAN (InsightFace inswapper_128). Nano FaceSwap Pro is built on a modern diffusion stack.
Diffusion-based identity pipeline
Not another inswapper_128 GAN. Our pipeline draws on InstantID, PuLID, IP-Adapter FaceID, and PhotoMaker research — delivering native high-resolution output, stronger identity lock-in, and natural skin texture.
100% local, 100% private
The desktop app runs entirely on your GPU. No cloud uploads, no telemetry, no per-minute fees. Unlike DeepSwap, Akool, HeyGen, or Reface, your photos and videos never leave your machine.
Temporally-consistent video
Video FaceSwap Pro uses optical-flow-guided identity propagation for frame-to-frame stability — smoother motion than Roop-Unleashed, FaceFusion, or Rope, even on long clips and fast head motion.
Fast on consumer hardware
Tuned for 8 GB NVIDIA GPUs and Apple Silicon (M2–M5). Batch a folder of images, swap a full-length video, or run the online demo in your browser — no data-center required.
Better lighting & color match
Most GAN-based swappers paste a face on; diffusion re-synthesizes it in context. Lighting, shadow direction, white balance, and film grain are preserved far better than Roop, Reactor, or SimSwap.
Image + video in one app
Most tools pick a lane — Roop for video, FaceFusion for both, InstantID for single images. Nano FaceSwap Pro unifies image and video swap in a single polished desktop app, with a shared identity model.

Frequently asked questions
Technical details on our diffusion face-swap pipeline and how it stacks up against the best tools in the world.
Is Nano FaceSwap Pro really free to try?
Yes. The online Image FaceSwap Pro and Video FaceSwap Pro demos are free for every signed-in NanoPocket account — no credit card, no watermarks on test outputs. The Pro desktop app also includes a free trial.
What makes Nano FaceSwap Pro a 'diffusion' face swap?
Most open-source tools (Roop, FaceFusion, Rope, Reactor, Deep-Live-Cam) are built on the InsightFace inswapper_128 model — a GAN with fixed 128×128 identity output. Nano FaceSwap Pro uses a diffusion-based identity pipeline inspired by InstantID, PuLID, IP-Adapter FaceID, and PhotoMaker research, combined with our own identity encoder. The result is higher resolution, better lighting adaptation, and far more natural skin texture.
Does Nano FaceSwap Pro run locally?
Yes. The desktop app runs 100% on your own GPU — NVIDIA CUDA on Windows and Apple Silicon (M2–M5) Metal on macOS. Your photos and videos never leave your machine. The free online demo is hosted by us for quick testing.
How is Nano FaceSwap Pro different from Roop, FaceFusion, or Rope?
Roop, Roop-Unleashed, FaceFusion, Rope, Rope-Live, and Deep-Live-Cam all share the same underlying inswapper_128 GAN, which caps output quality at 128×128 before upscaling. Nano FaceSwap Pro uses a native high-resolution diffusion pipeline, giving sharper skin detail, better lighting match, and stronger identity preservation — with a polished desktop UI instead of a Gradio script.
Is this a DeepSwap, Akool, or HeyGen alternative?
Yes. DeepSwap, Akool, HeyGen, DeepBrain, and Reface are cloud-based — they upload your video to their servers and charge per minute. Nano FaceSwap Pro runs entirely on your own hardware, with a one-time license, no per-minute fees, and no uploads.
Does it handle video face swap with temporal consistency?
Yes. Video FaceSwap Pro uses a temporally-aware pipeline with optical-flow-guided identity propagation, similar in spirit to DeepFaceLab and Rope-Live but built on a diffusion backbone. Faces stay stable frame-to-frame, even with strong head motion.
What hardware do I need?
Any modern NVIDIA GPU with 8 GB+ VRAM on Windows, or Apple Silicon (M2 and newer) with 16 GB+ unified memory on macOS. For the online demo, any modern browser works — the compute runs on our server.
Is diffusion-based face swap legal and ethical?
Nano FaceSwap Pro is a creative tool for consented use — portrait photography, film VFX, concept art, and personal projects. Non-consensual use of anyone's likeness is prohibited by our Terms of Use. Because it runs locally, you retain full control of every output.
