Backtest Visualizer
Backtest Visualizer is a free online tool that turns a CSV of daily returns or prices into an equity curve, an underwater drawdown chart, a monthly returns heatmap, and the stats that matter — Sharpe, CAGR, max drawdown. Everything runs in your browser; no data ever leaves the machine.
Your data
Loads a built-in 3-year synthetic series (~756 trading days, seeded so it's the same every time) — instant demo, no file needed.

Monthly returns
CSV format
Two columns: a date and either a return (per-day, as a decimal like
0.0031 or a percent like 0.31%) or a price (auto-detected). A header row is fine but optional.
date,return 2024-01-02,0.0031 2024-01-03,-0.0012Rows sort by date automatically. Messy rows are skipped and counted — nothing fails silently.
🔒 Privacy: parsing, stats, and charts all happen locally in your browser. Uploads never touch a server.
