Backtest like
a pilot.

How it works

From idea to backtest, in the browser

1. 01

   Pick a universe

   Choose your tickers, date range, and starting capital. Prices stream from Yahoo Finance through a CORS proxy — nothing to install.

2. 02

   Choose a strategy

   Momentum, mean-reversion, or smart-beta selection, sized by a Max-Sharpe, Min-Variance, or Equal-Weight optimizer.

3. 03

   Run it in your browser

   A web worker simulates day by day with real transaction costs and an S&P 500 benchmark. Zero backend — your data never leaves the tab.

4. 04

   Read, save & share

   Full metrics — Sharpe, Sortino, drawdowns, monthly returns — then save the run or publish it to the community leaderboard.
