UPDATE: they merged in my PR. Emulate now supports Gmail, Goole Calendar, and Google Drive APIs!
I set up Emulate Dev to replace Google's API with a local clone for Inbox Zero. It runs a fully stateful, high-fidelity emulator on localhost; no network, no rate limits, no OAuth headaches. I demo the full setup from config to a working Google login against the fake server.
00:00 What Is Emulate.dev?
00:45 Why Local API Emulation Matters
02:30 Setting Up Google OAuth Locally
05:32 Live Login Demo
06:17 Limits and Next Steps
1️⃣ Emulate Dev creates local drop-in replacements for Google & GitHub APIs
2️⃣ Fully stateful with an in-memory database — no external dependencies
3️⃣ Routes API calls to localhost ports instead of real endpoints
4️⃣ Google OAuth login works against the emulated server
5️⃣ Gmail API coverage is limited — plan to expand or contribute upstream
