Symulate: Accelerating Frontend Development with AI-Powered Mock APIs

Symulate is an AI-powered framework designed for modern web developers and agencies to rapidly build and demo frontend applications without waiting for backend APIs. It enables developers to define API endpoints with realistic, AI-generated mock data using TypeScript schemas, supporting full CRUD operations, stateful collections, and seamless switching to production with zero code changes. Built for speed and collaboration, Symulate supports React, Vue, Angular, and other JavaScript frameworks, offering type-safe development, team collaboration, and CI/CD-ready workflows. Its open-source SDK, available on GitHub under the MIT License, empowers developers to create isolated, tenant-specific demo environments with pre-generated data, drastically reducing demo creation time from weeks to hours.

Key Features:

• AI-Powered Mock Data Generation: Creates realistic, context-aware mock data using AI based on TypeScript schemas.
• Type-Safe Development: Full TypeScript support with automatic type inference from data schemas.
• Stateful API Mocking: Supports create, update, delete, and server-side pagination with stateful collections.
• Seamless Production Switching: Automatically switches to real backend APIs when NODE_ENV=production is detected.
• Framework Agnostic: Works with React, Vue 3, Angular, Nuxt, Svelte, SolidJS, and Remix.
• Team Collaboration: Shared data across devices, collaborative schema management, and team analytics.
• Isolated Demo Environments: Tenant demos with pre-generated, stable data per client.
• Multiple Persistence Modes: Memory, Local, and Cloud storage options.
• CI/CD Ready: Includes faker mode for unlimited testing, CLI, and CI/CD integration.
• Smart Caching: Reduces API calls and improves performance.
• Open Source & No Vendor Lock-In: SDK is open-source (MIT License) and supports BYOK (Bring Your Own Key) with OpenAI.
• Comprehensive Tooling: Includes API reference, starter templates, testing examples (Jest/Vitest, Playwright), and video tutorials.

Pricing: Symulate offers a Free tier with 20K AI tokens (non-resetting) and paid plans including Basic (1M tokens/month), Pro (5M tokens/month), Team (25M tokens/month), and Enterprise (150M tokens/month). Free plan includes unlimited organizations, projects, community support, and Faker.js fallback. Paid plans offer priority email support, shared cache, team analytics, and dedicated support.

Conclusion: Symulate is a powerful, developer-centric tool that streamlines frontend development and client demos with intelligent mock data and seamless integration. Its combination of AI innovation, open-source flexibility, and robust feature set makes it an essential asset for modern development teams and agencies looking to accelerate their workflow without compromising on quality or type safety.
