# Browser Harness

8 Hacker News commenters recommended Browser Harness and 3 criticized it, November 2025 to November 2026. It was recommended in 2 of 13 months.

**Verdict:** A small, inspectable tool that lets an AI agent drive a real browser with minimal infrastructure and full LLM freedom. The most common caveat is that raw CDP calls are harder to audit.

## Why people recommend it

- Small, minimal, inspectable design (2 comments): ""Minimal infrastructure, max LLM freedom" works great for personal automation." ([source](https://news.ycombinator.com/item?id=47919328)) "small, inspectable, and self-extending when the agent actually needs something" ([source](https://news.ycombinator.com/item?id=47927379))
- Flexible raw CDP access for agents (2 comments): "it trades one set of problems for another. When you let the LLM write its own CDP calls, you get flexibility but lose auditability" ([source](https://news.ycombinator.com/item?id=47899864)) "browser harness uses raw cdp, which is unrestrictive" ([source](https://news.ycombinator.com/item?id=47894085))
