CROSS-CATEGORY: Agent Runtime Infrastructure Charted on Product Hunt Twice in Two Days — Authorization and Cheap VMs

Product Hunt·medium signal

July 22's Product Hunt board shows agent plumbing, not agent apps: Kastra (199 votes) sells runtime authorization for Claude, Cursor, Codex and OpenClaw — policy enforcement against prompt injection and unauthorized tool calls — while box (183 votes) sells Ubuntu VMs with SSH for agents at $0.036/hr. Pairing these with July 21's Rerun (338 votes, agent building) and the July 18 'Clark' AI coworker that shipped its own cloud computer, the indie market has converged on the same conclusion in under a week: agents need an identity layer and a machine, and neither ships with the model.
