Show HN: Peek-CLI: let coding agents see your browser
Peek-CLI is an open-source tool that allows coding agents to view browser content, enabling them to interact with web pages during development or debugging tasks.
Background
- Peek-CLI is an open-source command-line tool (from PuffinSoft on GitHub) that lets AI coding agents like Claude Code, Cursor, or Codex see what's in your browser — by capturing browser screenshots, console logs, network requests, and errors, then feeding that data into the agent's context.
- It acts as a bridge between the coding agent and your browser, so the agent can visually inspect a web page it's building or debugging, without you having to manually describe what you see.
- Why it matters: AI coding agents currently work "blind" — they can write and edit code, but they can't see the rendered output unless a human describes it. Peek-CLI closes that loop, making agents much more self-sufficient at front-end debugging and visual inspection.
- Prior context: Tools like Puppeteer or Playwright already automate browsers programmatically, but Peek-CLI is designed specifically to integrate with conversational AI coding tools, giving them an eyes-on-the-page capability on demand.
