Descriptions:
David Ondrej provides a complete setup walkthrough for combining Hermes Agent with Browser Harness, a new library from the browser-use team that gives AI agents the ability to see, click, type, and self-heal across any website. Hermes Agent serves as the reasoning and planning layer, while Browser Harness acts as the execution interface—with the notable capability to write entirely new browser interaction functions on the fly when existing tools fall short.
The tutorial covers provisioning a Hostinger VPS pre-configured for Hermes Agent, cloning the Browser Harness GitHub repository, resolving a UV package manager dependency, and connecting the two systems end to end. Use cases demonstrated include posting to Twitter, scraping Hacker News, generating sales leads from LinkedIn, and producing a complete Mandarin-language video with Chinese text-to-speech and HTML rendering—all driven by natural language instructions to the agent. The browser-use team is reportedly offering a Mac Mini to the first person who identifies a browser task the harness cannot complete.
Ondrej also covers consolidating terminal commands into a public GitHub Gist for reproducibility, and discusses the option of using browser-use cloud as an alternative to running a local headless browser on the VPS. The video is aimed at developers looking to deploy persistent, browser-capable agents without deep DevOps experience, with an emphasis on using AI assistants like Claude to resolve setup blockers on the fly.
