A kill switch
for your AI agents.
When an agent goes sideways, you should not have to race to the terminal. Flip the kill switch from your phone and every gated tool call is denied until you say otherwise.
Featured on Hacker NewsOne move takes it all back
However autonomous your agents are, one person should be able to halt any of them immediately, without negotiating with the agent first.
One tap to halt
Flip the kill switch from your phone. You do not have to find the terminal, kill the process, or argue with the agent first.
Denies everything gated
While it is on, every gated tool call is denied, including the ones your policy would normally auto-approve. Nothing slips through.
From wherever you are
The switch lives on your phone, so a runaway agent does not depend on you being at your desk to stop it.
Stays off until you release it
The session stays halted until you turn the switch back off, so a stuck agent cannot quietly resume on its own.
Works across your agents
Halt a specific session whether the work is running in Claude Code, Codex, Cursor, or Hermes.
Why you can grant autonomy
The kill switch is not an admission the system failed. It is the thing that lets you hand an agent real freedom, because you can take it back in one move.
Keep the cord in reach.
Connect an agent and the kill switch is one tap away on your phone.
