Build Composer

Build your stack.

Pick roles, models and a harness; the quote reprices live from measured data. Plans travel in the share link.

Save a version to calculate break-even.

Break-even uses a common attempted-build volume: per-attempt role and harness cost × volume, plus each plan's fixed monthly cost. It does not infer success.

Local parity with Build Composer: plan editing, the org chart, sensitivity, break-even and gated exports all live here. Account saves, unlisted share links and price/budget alerts still live at Build Composer.
