our call

Start with Nacelle — highest vibe code, weakest moat.

Builder.io

Building a custom drag-and-drop canvas engine with dynamic React component bindings from scratch is a maintenance trap. However, using modern open-source visual tools like Puck or Payload CMS can eliminate the need for Builder.io for most teams.

you can rebuild

  • JSON page layout schema storage and API retrieval
  • Component prop configuration schema generation
  • Targeting and simple variant routing logic
  • Headless REST/GraphQL content endpoints
  • Draft and publish workflow status management

what you lose

  • Battle-tested WYSIWYG editor canvas across multiple viewports
  • Figma-to-React/Code automatic compilation visual toolchain
  • Multi-framework dynamic hydration engine (Next.js, Remix, Qwik)
  • Built-in visual A/B testing with edge-side split resolution
  • Enterprise role-based permissions and visual conflict resolution

real moats

  • Proprietary visual drag-and-drop canvas UI engine
  • Deep developer SDK maintenance across modern frontend frameworks
  • Figma integration that translates design auto-layouts into clean React code

Nacelle

Nacelle acts as a global edge cache and unified GraphQL gateway between backend commerce platforms (like Shopify) and frontend frameworks. While crafting a basic GraphQL proxy takes days, building a resilient indexing pipeline that handles burst webhooks and strict third-party rate limits requires enterprise engineering.

you can rebuild

  • Unified GraphQL API layer merging commerce and CMS payloads
  • Frontend helper SDKs for querying product catalogs
  • Basic data references linking Shopify products to Contentful models
  • Client-side event tracking dispatcher for analytics
  • Static site generation revalidation trigger handlers

what you lose

  • Managed globally-distributed edge caching for sub-100ms API responses
  • Built-in API rate limit and leaky-bucket algorithm abstraction for Shopify
  • Automated background data reconciliation when webhooks fail or drop
  • Pre-built resilient connectors for platforms like Shopify, Contentful, and Sanity
  • Enterprise SLA for infrastructure reliability during peak traffic events like BFCM

real moats

  • Battle-tested ETL data indexing pipeline operating under extreme concurrency
  • Deep integration lock-in across customer frontend UI components
  • Enterprise contracts with dedicated uptime and latency SLAs
