our call
Start with eCartApi — highest vibe code, weakest moat.
Branch
While generating short URLs that redirect to iOS Universal Links or Android App Links is trivial, Branch is fundamentally a Mobile Measurement Partner (MMP). Rebuilding its core SDKs, navigating Apple ATT restrictions, handling SKAdNetwork postbacks, and maintaining direct integration with Meta and Google ad APIs requires a dedicated infrastructure team.
you can rebuild
- Custom short link generation and domain management
- Basic iOS Universal Links and Android App Links configuration hosting
- First-party web-to-app user routing with logged-in query parameters
- Internal click tracking and link performance reporting
- Static QR code generation with deep link parameters
what you lose
- Deferred deep linking across native app store installs without user login
- Official MMP integrations with Self-Attributing Networks (Meta, Google, TikTok, Snap)
- Apple SKAdNetwork postback aggregation and conversion value mapping
- Edge-case resolution for broken WebViews in 50+ social and messaging apps
- Probabilistic matching fallbacks compliant with evolving Apple and Google privacy rules
real moats
- Certified MMP status and server-to-server integrations with Meta, Google, and Apple Search Ads
- Continuous engineering workarounds for iOS and Android OS-level browser redirection quirks
- Cross-app device graphs for privacy-compliant probabilistic attribution
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
