Peek-CLI: Let Claude Code See the Browser

Look, coding agents are getting terrifyingly good at writing code—but they can't see. They've been flying blind, unable to visualize what they're building in real-time. Until now.

Peek-CLI solves this with a brutally simple idea: let agents capture screenshots of any open browser tab. It streams screenshots over WebSockets via a browser extension, and it works with Claude Code, Codex, Copilot—basically any agent that can pipe in external tools. The problem it solves is obvious once you think about it: how do you debug a frontend when your agent can't see the UI? You don't. Now you can. It's open source, it's on GitHub, and it's exactly the kind of primitive that makes all the fancy AI coding tools actually useful in a real workflow.

This is the kind of tool that doesn't need a press release to matter. It's a building block—raw, useful, and probably already in the stack of every serious AI engineering team. The future of coding is agentic, and agents need eyes.
