our call

Start with Eye-Able — 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

Eye-Able

Building the frontend widget and automated WCAG crawler takes days using open-source libraries like axe-core. However, merchants buy accessibility software to avoid lawsuits and meet regulatory mandates, which a DIY script cannot guarantee.

you can rebuild

  • Client-side visual customization toolbar (font sizing, high contrast, color blind filters, link highlighting).
  • Automated WCAG 2.1 AA page scanning via headless browser engines.
  • Basic accessibility dashboard reporting visual contrast and missing alt attribute violations.
  • Screen reader reader-mode helper triggers and text-to-speech Web Speech API wrappers.

what you lose

  • Legal compliance backing, expert audit support, and formal WCAG compliance documentation.
  • Automated PDF document accessibility scanning and remediation tools.
  • Dedicated agency support and human-led accessibility verification.
  • Continuous automated site crawling with historical trend reporting.

real moats

  • Legal brand reputation and buyer trust regarding compliance certification.
  • Proprietary database of common ecommerce platform DOM patterns and automated fixes.
  • Bundled expert human auditing and PDF remediation capabilities.
