our call
Start with Glew.io — highest vibe code, weakest moat.
Convert
Writing a script that flips a coin and alters CSS is trivial, but building a production A/B testing suite is not. Convert handles ultra-fast edge dispatch without page flicker, sample ratio mismatch alerts, and GDPR-compliant cookieless tracking. Self-building the visual editor and statistical engine is inefficient for non-software vendors.
you can rebuild
- URL split redirects and query parameter routing
- Basic custom JavaScript and CSS injection per variant
- Simple 50/50 traffic allocation algorithms
- Event streaming to Google Analytics 4
- Basic device and URL path audience targeting
what you lose
- Visual point-and-click WYSIWYG DOM editor for non-technical users
- Sub-50ms anti-flicker edge execution logic
- Automatic Sample Ratio Mismatch (SRM) detection algorithms
- Cookieless ePrivacy and GDPR strict compliance frameworks
- Multi-page cross-session variant persistence without third-party tracking cookies
real moats
- Sub-50ms global CDN edge dispatch preventing page visual flicker
- Audited statistical significance and sample ratio mismatch calculation engines
- Deep privacy architecture for cookieless GDPR and CCPA compliance

Glew.io
Glew's UI and reporting math (LTV, AOV, RFM) are easily built with modern AI, SQL, and charting libraries. However, maintaining reliable, real-time data syncs across Shopify, Meta Ads, Google Ads, and Klaviyo requires continuous ETL pipeline maintenance.
you can rebuild
- Ecommerce KPI dashboard (Revenue, AOV, LTV, Orders)
- Customer RFM segmentation and cohort analysis
- Product performance and inventory velocity reporting
- Blended CAC and ROAS channel performance summary
- Scheduled email digest reports
what you lose
- Zero-maintenance multi-platform API integrations
- Pre-built normalized cross-channel data models
- Managed cloud data warehousing without DB admin work
- Automated historical backfills and rate limit retry handling
- Instant currency conversion normalization across platforms
real moats
- Broad library of maintained ETL connectors for ad networks and CRMs
- Standardized cross-platform data pipeline normalization
- Turnkey managed data warehouse syncing (Snowflake/BigQuery)
