How much did it cost to build this site? (building in public)
convomargin.pages.dev was built with AI agents in Cursor from mid-July into August. This page is a transparent log of prompts, failures, retries, and deploy reboots, with modeled LLM cost using the same calculator rates on the home page. Not invoiced data, but the kind of end-to-end trace ConvoMargin is built to automate.
TLDR: about 58 agent sessions, 8 failed production deploys, roughly $4.26 modeled LLM spend, $0 revenue so far, margin deeply negative. Headroom measured savings today: $0.00 (0 tokens). See note below.

Margin on this site
-$4.26
Modeled at mid-tier rates (same as the home calculator). Measured Headroom stats come from the local proxy
(/stats); updated when you run scripts/sync-build-log.ps1 and deploy.
MCP alone does not log API spend until the agent calls compress tools or Cursor routes API traffic through the proxy.
