Vibium

Vibium is a high-performance browser automation infrastructure purpose-built for the era of AI agents. Created by the founder of Selenium, it removes the "drama" from automation by providing a unified, reliable foundation that allows your agents to navigate, interact with, and extract data from the web with zero manual configuration.

Whether you are building complex AI workflows or modern test suites, Vibium handles the heavy lifting of browser lifecycles and protocol translations. It bridges the gap between Large Language Models (LLMs) and the live web, transforming a browser into a standardized tool that agents like Claude Code can operate natively via the Model Context Protocol (MCP).

Key Features

• ⚡ Integrated MCP Server: Vibium acts as a native MCP server, providing a standard interface for LLM agents. This allows tools like Claude Code to gain full browser interaction capabilities—such as clicking, typing, and navigating—through simple, standardized commands.
• 📦 Single-Binary "Clicker" Core: The heart of Vibium is a compact Go-based binary that manages everything from browser launching to WebDriver BiDi protocol routing. This architecture eliminates complex dependency chains, ensuring a consistent environment across different platforms.
• 🤖 Intelligent Auto-Waiting: To prevent script failures, Vibium automatically polls for elements before attempting interactions. By handling timing issues internally, it ensures your agent's actions are synchronized with the page's actual state without requiring manual sleep timers.
• 🌐 Automated Browser Management: You no longer need to manually install or update drivers. Vibium automatically detects, downloads, and configures the correct version of Chrome for Testing, ensuring your automation environment is ready to run the moment you install the package.
• 🔄 Dual Sync & Async APIs: Tailor your development to your specific needs with support for both synchronous and asynchronous execution. This flexibility allows for rapid prototyping in REPL environments while maintaining the performance required for production-grade agentic workflows.

Use Cases

• Enhancing AI Agents: You can grant Claude Code or other MCP-compatible agents the ability to perform live web research, fill out forms, or navigate complex web applications by simply adding Vibium as an MCP tool.
• Reliable Test Automation: Developers can use the JS/TS client to write robust end-to-end tests that benefit from BiDi-native speeds and automatic element waiting, significantly reducing "flaky" test results.
• Automated Visual Audits: Use the built-in screenshot capabilities to capture viewports as PNGs during automated runs, making it easy for agents to verify UI changes or archive web content for later analysis.

Why Choose Vibium?

Vibium stands out by prioritizing the developer and agent experience over legacy configuration requirements. While traditional tools often require meticulous setup of drivers and path variables, Vibium's "zero-config" philosophy means a single npm install handles the binary installation and browser provisioning for macOS, Windows, and Linux.

By leveraging the WebDriver BiDi protocol, Vibium offers faster, two-way communication with the browser compared to traditional JSON-over-HTTP methods. This technical foundation, combined with the pedigree of the Selenium project's creator, provides a level of reliability and foresight that is essential for building production-ready AI agents.

Conclusion

Vibium marks a shift toward a more invisible and efficient automation layer. By abstracting away the complexities of browser management and protocol handling, it allows you to focus on the logic of your agents and the value of your data. As AI continues to move from simple chat interfaces to active web participants, Vibium provides the stable, professional-grade infrastructure needed to navigate that transition with confidence.
