Hey Product Hunt community! 👋 I’m the maker of Mock Server Studio. While engineering mobile & frontend applications interacting with LLMs and live data streams, I hit two continuous roadblocks: 1. Burning paid OpenAI API tokens just to verify client-side token-rendering animations and streaming UI states. 2. The hassle of spinning up heavyweight mock containers just to test offline network resilience, custom latency delays, and 4xx/5xx handling. I built Mock Server Studio to solve this directly on-device. It turns your Android phone into an air-gapped, zero-config mock server across your local Wi-Fi or emulator network. 🔥 What you can do with it: • Native AI Token Streaming: Emits OpenAI-compliant `chat.completion.chunk` Server-Sent Events right to your frontend. • Multi-Protocol Suite: Full REST (with dynamic Faker tags), persistent bi-directional WebSockets, dynamic event tickers, and GraphQL matching. • Deep Traffic Inspector: Live latency stats, header/payload inspection, and 1-tap cURL command reproduction. • Seamless Workflow: Bulk import and export Postman collections and browser HAR files. • 100% Private: Operates completely on your device. Zero cloud relays, zero tracking. 🗺️ Roadmap preview: We are already architecting persistent on-device SQLite collections, an embedded MQTT broker, and MCP (Model Context Protocol) for upcoming releases! Pricing is developer-friendly: the free tier includes up to 5 concurrent routes with full protocol access, and Lifetime Pro is available for a one-time unlock (no recurring subscriptions). 🎁 Launch Giveaway: To celebrate our launch, I’m giving away free Lifetime Pro promo codes to the first 15 developers from the Product Hunt community today! Just drop a comment below with your use case, and I’ll send a code your way. I would love to hear your feedback, thoughts, and feature requests. Happy testing! 🚀
