🧬 SDXL Node Merger — Visual Model Merging Tool

Hey everyone! It's been a while.

I'm excited to share a tool I've been working on — SDXL Node Merger.

It's a free, open-source, node-based model merging tool designed specifically for SDXL. Think ComfyUI, but for merging models instead of generating images.

Why another merger?

Most merging tools are either CLI-based or have very basic UIs. I wanted something that lets me visually design complex merge recipes — and more importantly, batch multiple merges at once. Set up 10 different merge configs, hit Execute, grab a coffee, come back to 10 finished models. No more babysitting each merge one by one.

Key Features

🔗 Visual Node Editor — Drag, drop, and connect nodes with beautiful animated Bezier curves. Build anything from simple A+B merges to complex multi-model chains.

🧠 11 Merge Algorithms — Weighted Sum, Add Difference, TIES, DARE, SLERP, Similarity Merge, and more. All with Merge Block Weighted (MBW) support for per-block control.

⚡ Low VRAM Mode — Streams tensors one by one, so you can merge on GPUs with as little as 4GB VRAM.

🎨 4 Stunning Themes — Midnight, Aurora, Ember, Frost. Because merging should look good too.

📦 Batch Processing — Multiple Save nodes = multiple output models in one run. This is a game changer for testing merge ratios.

🚀 RTX 50-series ready — Built with CUDA 12.x / PyTorch latest.

Setup

Just clone the repo, run start.bat, and it handles everything — venv, PyTorch, dependencies. Opens right in your browser.

Would love to hear your feedback and feature requests. Happy merging! 🎉

Update: bugs related to saving checkpoints in complex multi-layer schematics and memory leaks have been fixed. Next up are fixes for a couple of visual bugs.
