h5i
WorkingAn open-source red-teaming browser for AI agents
What stands out
Taken from the page and the access facts we recorded. Nothing here is guessed.
- let an agent browse a web app under sandbox limits
- inspect and replay HTTP from an agent session
- No account required
- Free
- Source is public
What we checked
A missing tick means we have not measured it. A red mark is a check that failed.
App accessible
The project site answered. That is not the installed tool running.
Page rendered
No browser probe yet. An HTTP 200 is not this check.
Screenshot kept
We captured a picture of the page.

Evidence
Each bar is one request to the project's own siteThis one is installed and run on your own machine, so what we re-check is the project’s site — whether it is still published and still reachable. We cannot tell you from here that the tool itself runs.

We hash the visible text on every check, so a redesign registers and a rotating advert does not. An app that has not changed in a long time is not necessarily abandoned — but it is a fact worth knowing before you depend on it.
What it does
h5i is an open-source browser built in Rust. The page says agents can automate pages and control HTTP to test web apps, with sandboxing and auditable sessions. Install is a curl script.
What people say
No reviews yet.
We would rather show none than invent them.
Embed this status
Put it in your README. It updates itself every time we check, and links to your verification record — evidence a stranger can read, not a page selling them something.
