SpongeCake – open-source SDK for OpenAI computer use agents
Hey HN! Wanted to quickly put this together after seeing OpenAI launched their new computer use agent We were excited to get our hands on it, but quickly realized there was still quite a bit of set-up required to actually spin up a VM and have the model do things. So we wanted to put together an easy way to deploy these OpenAI computer use VMs in an SDK format and open source it Hopefully this tooling is helpful to other folks building AI agents! Here’s a link to the repo (https://github.com/aditya-nadkarni/spongecake) - please try it out and give us a star. If you have…

In plain words
SpongeCake is an open-source SDK that simplifies deploying OpenAI computer use agents by handling the setup required to spin up virtual machines. It provides developers with an easier way to get AI agents running without extensive configuration. The tool is designed for developers building AI agents and aims to reduce friction in the initial deployment process.

Open Source Operator for Computer Use Using spongecake to automate linkedin prospecting (see examples/linkedin_example.py) 🍰 spongecake is the easiest way to create your own OpenAI Operator that can use computers. These agents can scrape, fill out forms, and interact with websites or local apps. It helps: git clone https://github.com/aditya-nadkarni/spongecake.git cd spongecake Run the setup script : chmod +x setup.sh # May be required on Unix/macOS ./setup.sh Run the backend and frontend : cd spongecake-ui cd backend python server.py Note: This deploys a Docker container in your local Docker environment. If the spongecake default image isn't available, it will pull the image from Docker…from github.com

An open-source Operator that can use computers2025 · github.com · ▲9Hi HF, I'm Terrell, and we built an open-source app that lets developers create their own Operator with a Next.js/React front-end and a flask back-end. The purpose is to simplify spinning up virtual desktops (Xfce, VNC) and automate desktop-based interactions using computer use models like OpenAI’s There are already various cool tools out there that allow you to build your own operator-like experience but they usually only automate web browser actions, or aren’t open sourced/cost a lot to get started. Spongecake allows you to automate desktop-based interactions, and is fully open…
