Excerpt

Driving h5i-browser-light

A headless browser for agents. What makes it different from the others is not speed: the engine is the HTTP client, so its request log is not an observation of the network, it is the network. Nothing it fetches escapes the allowlist, and nothing it fetches goes unrecorded.

h5i-browser-light <command> --help is the authoritative flag reference and cannot go stale. Reach for it before guessing at a flag.

Start a session, then drive it

open renders a page and exits, so two opens share nothing — no cookies, no history, nothing to click. Anything interactive needs a resident session:
