Strong idea

StackDiff builds a side-by-side view of your current tooling against a proposed one, with cost, effort and risk per component. It turns migration debates into a single reviewable document.

1Build StackDiff, a web app for comparing a current technology stack against a proposed one. Users create a comparison, add components by layer (hosting, database, auth, payments, analytics, monitoring), and fill in current and proposed choices with monthly cost and notes. The app produces a summary with total cost delta, a migration effort estimate per component, a risk flag list, and an ordered migration plan. Include a comparison library, duplicate-and-edit, a shareable read-only link and a printable decision summary. Use authentication, a database for comparisons and components, and an AI model to generate the effort estimates, risks and migration order from the entered components. Design it technical and precise with tables, monospace numbers and a light theme.
