Modernize with AI — reviewed by humans.
Theme Runner drafts the complex merges between your custom code and the latest Stencil or Catalyst release. MoJo Active's BigCommerce Elite Partner engineers — with 8+ years on the platform — review every change before it ships.
Four Steps — AI & Expert, Side by Side
Our AI-driven pipeline handles the technical debt, and MoJo Active's BigCommerce engineers review every merge before launch.
Connect your storefront
Securely link your Stencil or Catalyst codebase via API or GitHub. Theme Runner creates a sandboxed snapshot without touching your live production environment — whether your Catalyst app lives on Vercel or BigCommerce Native Hosting.
- check_circle Stencil (Cornerstone, purchased, or custom)
- check_circle Catalyst on Vercel or BigCommerce Native Hosting
- check_circle Zero-downtime integration
AI analyzes theme & updates
Our engine maps your custom modifications against the latest Stencil or Catalyst release, surfacing semantic conflicts, deprecated components, and performance bottlenecks — the groundwork your Elite Partner reviewer will audit.
"AI identified 12 structural conflicts and 34 styling overrides in 0.4 seconds."
Elite Partner review & automated QA
Every AI-drafted diff lands in front of a MoJo Active BigCommerce developer. They pair the automated regression suite with 8+ years of platform experience — interrogating edge cases your AI (and ours) might miss.
Launch after sign-off
With automated tests green and a MoJo Active engineer's approval on the record, Theme Runner ships a production-ready package to Stencil, Catalyst on Vercel, or BigCommerce Native Hosting — one click, full audit trail.
