| Description | 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. | LangWatch is an open-source, framework-agnostic platform for testing, evaluating, observing, and optimizing AI agents and LLM applications. It uses simulation-based testing with real-user text and voice conversations, LLM-as-a-judge evaluations, red teaming, and OpenTelemetry-native observability to catch issues and prevent regressions. It supports collaboration between technical and non-technical teams and can be deployed as cloud, self-hosted, or hybrid. |
