BrowserOS neo vs Fellou

BrowserOS neo is a free, open-source browser that lets AI agents operate through browser sessions you are already signed into. Agents can open tabs, navigate, click, and read pages while you remain signed in. The browser connects through MCP to Claude Code, Claude Cowork, Cursor, Codex, VS Code, Zed, and GitHub Copilot. Multiple agents can work in separate tabs while you browse. Each run is saved as a scrubbable video for replay. The maker says sessions, screenshots, replays, settings, and logins stay on your machine rather than being sent to its server. Chrome logins can be imported in one click. BrowserOS neo sends compact page snapshots instead of raw HTML and can batch actions in one call. It runs on Linux, macOS, and Windows, uses Chromium, and is licensed under AGPL-3.0. It is free, has no free trial, and requires your own AI provider keys.

Fellou is an agentic AI browser for automating web and desktop work on macOS. Users describe a task in natural language, then can review, edit, or approve the step-by-step workflow before it runs. Its research tools work across the internet, including logged-in accounts such as Reddit, and create reports with verifiable sources. Browser Use can scrape data and fill forms; with permission, Computer Use can operate local apps and manage files. Workflows can connect apps, with LinkedIn-to-Notion data transfer given as an example, and can be scheduled once or on a recurring basis. Users can monitor progress and intervene during execution. Developers can use the open-source Eko 2.0 framework to build custom agents with natural language and JavaScript. A free plan is listed, alongside paid options including Plus at $19 a month and Pro at $39.90 a month. Fellou says Spark use varies significantly with workflow complexity, so task estimates are approximate. Its privacy policy says service content and output may be used to improve services after encryption and de-identification; users can object to data use for service training.
