Crash Survival Score
See exactly where your portfolio breaks across −30%, −50%, −70%, and −80% drawdowns. Know your threshold before the market finds it for you.
Ruin Test
The framework question: if BTC drops 80% and everything else drops 40%, do you survive? One scenario. One answer. No ambiguity.
Local-First
Your data stays on your machine. No cloud, no accounts, no tracking. Built for people who treat privacy as a prerequisite, not a feature.

No dashboards. No subscriptions. No data leaving your machine. Open a terminal, run the command, and know your number in under a minute.
