Nova vs chrome-devtools-mcp

Nova: Nova is a Rust-native implementation of "computer use" capability for LLM agents, enabling AX-first control over macOS and Windows through semantic UI interactions, screenshots, OCR, and various input methods. It acts as a Model Context Protocol server, offering robust and direct system-level automation without relying on Python/JS stacks.; chrome-devtools-mcp: chrome-devtools-mcp enables AI coding assistants like Gemini, Claude, and Copilot to interact with a live Chrome browser via the Model-Context-Protocol (MCP). It grants AI full access to Chrome DevTools for reliable automation, deep debugging, and detailed performance insights.

When to choose:
  • You want an agent to record a Chrome performance trace and get insights from it; the README lists performance_start_trace, performance_stop_trace and performance_analyze_insight.
  • You need to inspect network requests, console messages and screenshots of a page while debugging it.
  • You want the agent to attach to a Chrome you already have running, using --browser-url, --ws-endpoint or --autoConnect (Chrome 144+).
When to skip:
  • You need Firefox or Safari: the project is built on Chrome DevTools and targets Chrome.
  • You want a general-purpose automation or test runner across browsers; Playwright MCP is the closer fit.
  • You cannot run Node.js 20.19 or newer, which the README lists as a requirement.
