Shopify issues we fix before deploying
Common Shopify problems that affect Fly.io deployments.
Slow theme performance
AI-generated Liquid templates with too many nested loops, unoptimized images, render-blocking scripts, and missing lazy loading — increasing page load time and hurting conversion rates.
Broken checkout customizations
Custom checkout scripts or Shopify Functions that break the checkout flow for certain payment methods, shipping options, or edge cases like discount stacking.
Insecure custom app webhooks
Shopify app webhook endpoints without HMAC signature verification, allowing attackers to send fake order, payment, or customer data to your systems.
API rate limit violations
Custom integrations that hit Shopify's API rate limits by making too many requests without proper throttling, causing sync failures and data inconsistencies.
Fly.io deployment issues we check for
Common Fly.io problems that break Shopify apps in production.
Dockerfile missing or misconfigured
Fly.io requires a Dockerfile for deployment. AI tools that scaffold without one force flyctl to auto-generate a suboptimal Dockerfile that misses build steps.
Volume only available in a single region
Fly volumes are pinned to one region. Multi-region deployments try to access a volume that doesn't exist in other regions, causing crashes.
Machine restarts losing in-memory state
AI-generated apps store session data or caches in memory. Fly machines can restart or migrate, wiping all in-memory state without warning.
Internal DNS resolution failing between services
Services within a Fly organization communicate via <app>.internal hostnames, but AI-generated code hardcodes localhost or public URLs.
