AI drafts. Experts decide.
Theme Runner combines our AI merge engine with MoJo Active's BigCommerce Elite Partner team — 8+ years of Stencil and Catalyst experience sanity-checking every update before it goes live.
AI-Drafted Code Adaptation
Our engine proposes refactors for legacy blocks, maps dependencies, and rewrites logic against the latest framework. A MoJo Active BigCommerce engineer then reviews the diff before it merges — AI speed with expert accountability.

Automated & Human QA
Theme Runner scans every viewport and component state, flagging visual regressions, accessibility gaps, and layout shifts. A MoJo Active developer then triages the findings and confirms the launch — nothing ships on pixel diffs alone.
Performance Optimization
Deep-level asset optimization and runtime analysis. Theme Runner identifies bottleneck scripts and non-performant queries, suggesting surgical fixes that boost Core Web Vitals by up to 60%.
One-Click Rollbacks
