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.
