Product Hunt

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.
