Show HN: Vibium – Browser automation for AI and humans, by Selenium's creator

Summary

Vibium Browser automation without the drama. Vibium is browser automation infrastructure built for AI agents. A single binary handles browser lifecycle, WebDriver BiDi protocol, and exposes an MCP server — so Claude Code (or any MCP client) can drive a browser with zero setup. Works great for AI agents, test automation, and anything else that needs a browser. New here? Getting Started Tutorial — zero to hello world in 5 minutes.
