Promptgate

Read full description

Promptgate Cloud is a developer tool for routing instructions, approvals, and status updates between people and automated processes through simple HTTPS gates. It is built for human-in-the-loop workflows where an AI coding agent, deployment script, build server, or background job needs to wait for your input, send a result, or request approval without a custom backend. Use Promptgate to: - Send instructions to AI agents from a native iPhone or Mac console - Add manual approval steps to CI/CD and release scripts - Monitor agent responses, build status, and automation logs in one place - Create reusable cloud gates with copyable HTTP endpoints - Let scripts post new items to a gate through secure secret URLs - Receive push notifications when a gate is consumed or a new message arrives Promptgate works with standard tools such as curl, shell scripts, JavaScript, Python, and custom automation. Create a gate, copy the generated endpoint, and connect any process that can make an HTTP request. Your agent can wait for an instruction, stream heartbeat messages while it is waiting, post a short response, or send a new item into the gate. Each gate includes configurable passwords, prompts, timeouts, heartbeat text, message history, notification settings, and delete/clear controls. The native app gives operators a focused dashboard for gate management, chat-style coordination, and fast copy actions for integration snippets. Promptgate Cloud is designed for developers, DevOps teams, automation builders, and AI-agent operators who need a lightweight control layer between scripts and human decisions. Subscription notice: Promptgate Cloud is a subscription-based service. Creating and using hosted cloud gates, posting operator messages, and allowing automated agents to poll gates require an active subscription purchased through Apple in-app purchase. Subscription terms, renewal details, cancellation options, Terms of Service, and Privacy Policy are shown in the app before purchase. Privacy notice: Promptgate stores the anonymous account identifier, gate settings, and the messages or payloads that you intentionally send through your gates so the service can display and deliver them. Do not route secrets or sensitive production data unless you are comfortable storing that content in your Promptgate Cloud account.

See exactly how your prototype behaves with real materials, real motion before anyone else does so every reviewer sees the same high-fidelity preview. No builds to distribute, no TestFlight invites to chase. WHY PROTOTO Design tools render an approximation of native apps.
