BrowserOS neo is an open-source, Chromium-based agentic browser positioned as a privacy-first alternative to cloud-run browser agents like Perplexity's Comet. It has a Chrome-like interface and supports existing Chrome extensions, but adds a local AI agent layer that can browse and take actions on a user's behalf using either the user's own API keys or fully local models via Ollama — keeping browsing data on the user's own machine rather than sending it to a cloud AI provider. Because agents run in the user's actual browser rather than a headless cloud instance, they inherit the user's real logins and sessions instead of needing separate authentication. BrowserOS also exposes an MCP-compatible interface, so external coding agents like Claude Code, Cursor, Codex, VS Code, Zed, or GitHub Copilot can drive the browser directly with a one-click install. The project is licensed under AGPL-3.0 and its source is maintained across several repositories under the browseros-ai GitHub organization.

Gemini CLI is Google's open-source, Apache 2.0-licensed command-line AI agent that connects Gemini models (with a 1M-token context window) directly to your terminal for coding, debugging, automation, and research. It's built for developers who work in the command line, offering a free tier with a personal Google account plus built-in Google Search grounding, file and shell operations, and multimodal generation. Its main differentiator is the direct, lightweight path from prompt to Gemini combined with extensibility via Model Context Protocol and native GitHub Action workflows.
