Rubbrband – A hosted ComfyUI alternative for image generation
Hey HN! My friends and I built a new platform for generating images. The app is easy to use for people who find ComfyUI hard to use, or just simply don’t have a GPU to use it on. For those not familiar, ComfyUI is a great tool for using open-source models like Stable Diffusion. It’s primarily great because it’s a node-based tool, which means you can chain together models, upscalers, prompting nodes, etc… which let you create images in the exact aesthetic you want. There’s also a vibrant dev community behind ComfyUI, which means that there are a ton of nodes and customizability. We’re users…

In plain words
Rubbrband is a hosted web-based platform for generating images using open-source models like Stable Diffusion. It simplifies ComfyUI's node-based workflow for users without access to powerful GPUs or those who find the original interface difficult. The platform allows users to chain together models, upscalers, and prompting nodes to create customized images, making advanced image generation accessible to those without high-end hardware.

Hey HN! We’re the founders of Rubbrband (https://www.rubbrband.com/), a evaluation platform for image generation models like Stable Diffusion. We provide a monitoring application to detect deformed human features in AI generated images at scale. For example, we automatically flag images of people with deformed eyes or hands. We’ve worked with several companies leveraging generative image models in production, and found that one of the main problems is that it’s hard to filter images for good quality sample at scale. Typically, teams will have to manually look through the…
A free text-to-image website that supports SDXL Turbo2023 · comfyuiweb.com · ▲35The homepage of the website allows for free image generation, and in the workflows, there are introductions to nodes related to ComfyUI. In the AI tools section, Pixart-Alpha is currently available for free use. I am still updating this website, and feedback and communication are welcome.
InvokeAI, an open source Stable Diffusion toolkit and WebUI2022 · github.com · ▲414Hey everyone! Excited to be able to share the release of `InvokeAI 2.0 - A Stable Diffusion Toolkit`, an open source project that aims to provide both enthusiasts and professionals a suite of robust image creation tools. Optimized for efficiency, InvokeAI needs only ~3.5GB of VRAM to generate a 512x768 image (and less for smaller images), and is compatible with Windows/Linux/Mac (M1 & M2). InvokeAI was one of the earliest forks off of the core CompVis repo (formerly lstein/stable-diffusion), and recently evolved into a full-fledged community driven and open source stable…
Open-source app builder for comfy workflows2024 · github.com · ▲59Hey, we’ve been working on an open-source project built on top of Comfy for the last few weeks. It is still very much a work in progress, but I think it is at a place where it could start to be useful. The idea is that you can turn a workflow into a web app with an easy-to-use UI. Currently, it should work with any workflows that take images and text as input and return images. We are aiming to add video support over the next few days. Feedback and contributions are more than welcome!
