our call
Start with Plattar — highest vibe code, weakest moat.
eCartApi
While building a single standardized schema wrapper for 2-3 carts takes days, maintaining auth, webhooks, and breaking API updates across 30+ platforms requires dedicated engineering bandwidth. You aren't paying for complex algorithms; you are paying for platform adapter maintenance and rate limit handling.
you can rebuild
- Unified JSON schema mapping for product and order payloads
- Developer dashboard for API credential and token management
- Webhook relay and event standardizing across platforms
- Basic REST proxy middleware between application and cart endpoints
- Request and response logging with audit trails
what you lose
- Pre-built connectors and OAuth flows for 30+ ecommerce platforms
- Automatic maintenance for third-party API version deprecations and breaking changes
- Built-in rate limiting queues and platform throttling management
- Unified error handling and standardized response normalization
- Managed infrastructure for secure third-party store token storage
real moats
- Massive ongoing engineering footprint to maintain 30+ cart API adapters
- High integration lock-in once app backend relies on unified endpoints
- Platform version deprecation tracking and automated fallback handling

Plattar
Plattar wraps standard WebGL primitives and native mobile AR engines into a hosted CMS. You can replace its core viewing and AR capabilities using open-source libraries in a single weekend.
you can rebuild
- WebAR launch triggers for iOS AR QuickLook and Android SceneViewer
- 3D product preview iframe and custom element embed script
- Basic 3D variant switcher (changing colors, textures, and geometry)
- Camera control configuration (zoom limits, auto-rotate, pitch bounds)
- Product annotation hotspots with HTML overlay callouts
what you lose
- No-code visual node builder for complex product logic trees
- Automated cloud-based 3D mesh decimation and texture compression
- Turnkey enterprise SLA for high-concurrency 3D model CDN delivery
- In-house 3D asset modeling and conversion services provided by Plattar staff
- Pre-built analytics dashboards for tracking WebXR user interactions
real moats
- Enterprise contracts with managed 3D asset creation services
- Proprietary visual configuration rule engine for complex industrial products
- High switching costs created by manual entry of material option matrices
