“We assumed our biggest account was one very busy person. It was Claude in Chrome, running all night on a starter seat. Switchfrog flagged it during the session, not in a report three weeks later.”
Your customers are bringing agents.
Tools like Claude Cowork and OpenClaw run inside the customer’s own logged-in session, on the same device with the same cookies, so from the edge nothing looks wrong.
Switchfrog reads how the browser is being driven and flags the handover as it happens, while there’s still time to do something about it.

Install once. Know every session.
Switchfrog reads the session itself, not just the traffic, so it can tell a person from an agent on the same account.

One seat, used like an API.
A starter seat was priced for a person who works a few hours a day in one tab. An agent on that login runs all night and never opens a support ticket. Switchfrog shows you which seats are agents and how much they run, then hands the verdict to your billing system by webhook so the seat can be billed like the API it has become.

While we’re in private beta the free tier is the whole product, and there’s nothing to pay.

Frequently asked questions
Software driving the browser on a person’s behalf: Claude in Chrome, Claude Cowork, OpenClaw, Codex and the like. Switchfrog reads how the session is being driven rather than who is logged in, so it catches the handover even when the agent is using a real customer’s account.
A session where the signal isn’t strong enough to call it either way. Those are kept apart from the Human and Agent counts rather than guessed, so you can decide how to treat them.
Yes. It’s one tag on the pages your customers already use. Nothing changes about your login, your SSO or your identity provider, and there’s no SDK or proxy to run.
How the session is driven: input timing, pointer movement and navigation. It is there to tell a person from an agent, and it doesn’t need the contents of what people type or see to do that. Switchfrog is ISO 27001 certified and SOC 2 compliant.
While the session is still open. Each session is classified within milliseconds and the verdict is available by webhook or API straight away, so you can act on it before the session ends.
No. It tells you what’s driving the session and leaves the decision to you: allow the agent, flag the account, or move the seat onto agent pricing.
That’s the point. The verdict reaches your billing system by webhook, so a seat that turns out to be an agent can be metered like the API it has become. We’re pricing agent-seat billing with the beta customers who use it first.
Nothing during the private beta: the free tier is the whole product, with no card and no time limit. Request access with a work email and we reply within two working days.
