Switchfrog shows product teams which AI agents are using their website and what they are doing. AI browser agents such as Claude in Chrome, OpenClaw, Codex and Cursor now operate through real customer accounts, bypassing traditional bot detection — Switchfrog reads how a session is driven, from input timing and pointer movement to navigation, and classifies it as human or agent within milliseconds. The dashboard breaks sessions down by human, agent and unknown, shows which accounts bring agents, where they go and what they do, and flags seats whose usage has jumped because an agent runs all night on a login priced for a person. Teams can then allow the agent, block it, or bill it as an agent seat, with verdicts delivered by webhook or API while the session is still open. Installation is a single line of code with no proxy and no change to login or SSO. Agent-seat billing is being priced with early beta customers. It suits SaaS teams whose customers already bring AI agents to work and who need to see, measure and price that usage instead of guessing.
