Switch to Production in 1 Line

When your backend is ready, just update the environment

config.ts
import { configureSymulate } from "@symulate/sdk";

configureSymulate({
  environment: 'production', // 👈 Just change this!
  backendBaseUrl: 'https://api.production-app.com'
});

Intelligent Caching

Smart caching delivers sub-10ms response times after first generation

Type-Safe Architecture

The Paradigm Shift

Traditional development waits for backends. Symulate flips it upside down.

Traditional Way

1
Wait for API specs
Backend team defines contracts
2
Wait for implementation
Backend builds the actual endpoints
3
Build frontend
Finally start UI development
4
Integration hell
Fix mismatches and bugs
Timeline: Weeks to months

Symulate Way

1
Define your schema
Use semantic types, get instant mocks
2
Build complete UI
AI provides realistic data instantly
3
Demo to stakeholders
Show working prototypes, get feedback
4
Flip the switch
Connect real backend when ready
Timeline: Hours to days
<10ms
Cached Response Time
100%
Type-Safe TypeScript
