BrowserOS neo vs MoltBrowser

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.

MoltBrowser is a free, open-source AI browser with an embedded on-device model and privacy features. Its page-aware AI can summarize articles, explain code, extract table data, and translate pages. It runs open models such as Llama, Mistral, Phi, and Qwen locally; the project also documents using personal keys with OpenAI, Anthropic, Gemini, and compatible endpoints. Its agent can click, scroll, navigate, and fill forms, and tasks can be scheduled to run automatically. Browsing memory and AI conversations are stored on the device; conversation history can be searched, exchanged as JSON, or wiped in one action. MoltNet routes traffic over Tor and allows exit-country selection, while MoltShield blocks ads and trackers, including YouTube ads, and dismisses cookie banners. The maker says the browser alters device fingerprint signals and masks the user's IP address. Builds are listed for Apple Silicon macOS, Windows 10/11 x64, and Linux x64. Chrome extension compatibility is advertised. iOS and Android are listed as in development, not as available builds.
