custom javascript

Custom Javascript matters only if the evidence supports a paid workflow around shipping custom code and site changes without breaking production, not a list of isolated fixes. The current commercial thesis is: Custom code, snippets, headers, and editor changes can silently break sites or create hard-to-debug handoffs. The entry wedge is to preflight custom code changes, detect risky snippets, and package rollback-ready diagnostics.

Opportunity Summary

Full report

Build a developer change safety and site customization plugin for developers, agencies, and technical site owners: Custom code, snippets, headers, and editor changes can silently break sites or create hard-to-debug handoffs. The first wedge is to preflight custom code changes, detect risky snippets, and package rollback-ready diagnostics.

The unmet need is not the individual complaint. It is the recurring business workflow: Custom code, snippets, headers, and editor changes can silently break sites or create hard-to-debug handoffs. Current stage: commercial watchlist.
