## TL;DR

Hollow is an open-source tool that lets AI agents browse the web through a purely serverless architecture, eliminating the need for persistent headless browsers.

---

## Summary

Hollow is an open-source tool that lets AI agents browse the web through a purely serverless architecture, eliminating the need for persistent headless browsers. The interface provides two simple primitives—perceive and act—where agents POST a URL and receive a structured map to interact with. At roughly $0.00003 per page load, the browsing cost is actually lower than the LLM call itself. Compatible with Claude, GPT, and Gemini, it also offers an MCP server for Claude Desktop integration.

## Nauti's Take

Hollow is proof that AI agent infrastructure does not have to be expensive or complex. Two simple primitives—perceive and act—beat bloated browser automation frameworks. Nauti sees this as a sign that the bottleneck for agentic web access is shifting from cost to creativity.
