Preloop is the human approval layer for autonomous AI agents. When your agents attempt risky actions like deployments, refunds, or data changes, Preloop intercepts the request and routes it to you for approval right on your iPhone or Apple Watch. The right people in your organization get instant notifications with full context, approve or decline with one tap, while your organization maintains a complete audit trail for compliance. Preloop enables event-driven automation through Agentic Flows - let AI agents handle routine work automatically while you control critical decisions. Setup takes 3 minutes as an MCP proxy, works with Claude and Cursor, and requires no infrastructure changes. Risk-based policies ensure only high-stakes actions need approval while low-risk operations run automatically. AI agents can't take legal or moral responsibility for their actions - Preloop ensures humans stay in control. Perfect for engineering teams, DevOps, and anyone deploying autonomous AI in production. Enterprise-ready, designed for SOC2 compliance, role-based access, and secure end-to-end encryption.
