What is this repo actually made of, and how much would it cost to develop?

Paste any public GitHub URL. In a few seconds you'll see how many lines of code it has, which languages, where the complex files live, and a COCOMO-based estimate of how much it would cost — and how long it would take — to build the same thing from scratch.

About the cost estimate (COCOMO)

COCOMO — the Constructive Cost Model — is a software cost-estimation algorithm developed by Barry Boehm in 1981 and calibrated against 63 industrial software projects. It translates codebase size (in thousands of lines of code) into estimates of effort (person-months), schedule (calendar months), and team size, using empirically-fit power-law equations.

This site applies COCOMO's organic mode — the calibration for small-to-medium projects built by experienced developers in a familiar environment:

effort = 2.4 · KSLOC^1.05 person-months
schedule = 2.5 · effort^0.38 calendar months
people = effort / schedule
cost = effort × $4,690/mo salary × 2.4 overhead ($56,286/yr base salary)

These are model-driven estimates from an industry-standard formula — not a quote, not a contract bid. They're useful for comparing repos and for ballparking "how much engineering work is sitting in this codebase."
