Launching tomorrow: Symulate - Build complete UIs before your backend exists
Hi guys, I'm Emilio from Symulate.I'm so excited to present Symulate to you, launching tomorrow at 12:01 AM PST. It's a tool that allows development teams to flip their workflow upside down. Instead of making the frontend team wait for the backend team to finish the API, or even putting a ton of effort into manually creating fake data, you can now use Symulate. Just define your endpoints in your frontend using the Symulate SDK, give it schemas that match exactly what you expect from the endpoint and watch your UI get filled with realistic fake data. Then you can export your endpoints as an OpenAPI file or view them on the Symulate platform, allowing the backend team to make endpoints that match exactly what the frontend needs. Once the backend is ready, switch with one configuration change. You already defined everything Symulate needs to know in order to send the requests to your actual backend. No wasted code!There are many advantages to this, but the biggest ones are a ton of saved time and headaches + the ability to create flexible demos for customers super quickly. What do you think? Will you try it out? 20K tokens are included in the free plan.Looking forward to seeing you at the launch tomorrow!

Symulate - Build complete UIs before your backend exists
Frontend devs know the pain: You have a great UI idea, but you're blocked waiting for backend APIs. Symulate changes that.
Define your API endpoints in TypeScript, and get instant AI-powered mock data that feels real. Build your entire UI, demo it to stakeholders, gather feedback, and iterate, all before writing a single line of backend code.
Once the backend is ready, change one configuration to use it. No wasted code.
Stop waiting. Start building.
