AIHawk (now published under the name invisible_playwright_mcp, with AIHawk kept as its established brand) is an open-source anti-detect browser and web-browsing agent built on Playwright, distributed as an MCP server so coding assistants like Claude Code, Codex, and Gemini CLI can browse the web without triggering captchas or anti-bot blocks. It ships two ways to use it: as an MCP server plugged into an existing coding assistant, or as a standalone web UI (a chat panel next to a live browser view) that works with any OpenRouter model and key. The engine drives a stealth Firefox build with configurable proxy, browser-fingerprint seed, and persistent profile support, so logins and cookies survive across restarts. Everything runs locally with no server of AIHawk's own: the sites visited see the browser as any normal Firefox would, and only the assistant's own model provider sees the conversation. The project has 31,700+ GitHub stars and 4,700+ forks, and its author previously built the well-known LinkedIn auto-apply tool under the same AIHawk name.

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.
