Partial Beta, what-if reweighting, and sector views are straightforward math and UI. The product depends on reliable, licensed historical price data for every holding, which a solo builder may struggle to obtain cheaply.
What it would actually take: The stack would be a web app with a backend that computes regressions of daily returns against a market index, plus a broker-CSV parser. The hard part is a dependable source of adjusted and unadjusted historical prices and sector metadata, often under paid data licenses. Accuracy of the 'typical-miss' ranges also requires quantitative finance knowledge to validate.
