Open-source alternatives to Claude in Chrome

I want to pick an open-source replacement for Claude in Chrome. Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - Nanobrowser: Nanobrowser is a free Chrome and Edge extension where you type a task in a side panel, and an AI agent reads web pages, clicks, types and moves between tabs to finish it. It is for everyday people who want help with browsing tasks and who can bring their own AI model key or run a model locally. [Easy setup; Windows · Mac · Linux; replaces fully; Apache-2.0; https://github.com/nanobrowser/nanobrowser] - BrowserOS: BrowserOS neo is a second web browser that AI assistants can control, so they can do tasks like posting to social media or sorting email on your own logged-in accounts. It is aimed at people who already use AI agent tools and want them to work in a browser on their own computer. [Easy setup; Windows · Mac · Linux; replaces fully; AGPL-3.0; https://github.com/browseros-ai/BrowserOS] - Skyvern: Skyvern is a tool that uses AI and computer vision to control a web browser, so it can click, read and fill in websites in place of a person. It is aimed at both programmers and non-technical users who want to automate repetitive online tasks. [Advanced setup; Windows · Mac · Linux; replaces fully; AGPL-3.0; https://github.com/Skyvern-AI/skyvern] - Browser Use: Browser Use is free open-source software that lets an AI assistant control a web browser to click, read, and fill in websites for you. It is aimed mainly at programmers and developers who build automated browser tasks, though it can also be run through other AI tools. [Advanced setup; devices not listed; replaces partly; MIT; https://github.com/browser-use/browser-use] - Stagehand: Stagehand is a toolkit that lets programs control a web browser and use AI to click, read, fill in forms, and pull data from websites. It is for programmers and developers who want to automate browser tasks in TypeScript, Python, or Go. [Advanced setup; Windows · Mac · Linux; replaces partly; MIT; https://github.com/browserbase/stagehand] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/browser-agents.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/browser-agents.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
