Is there a free tool to compare stocks or securities?

Yes. QRep compares up to 6 securities against a benchmark, computing 81 QuantStats metrics for each (CAGR, Sharpe, Sortino, maximum drawdown, and more), and returns HTML and PDF reports with technical-analysis charts, performance KPIs and risk metrics. It is built on the original ranaroussi/quantstats library and exposes an open MCP endpoint with no key, so an AI agent can call it as a tool.

Open the app at qrep.tigzig.com. The API and MCP reference is at https://www.tigzig.com/apis/qrep. For a single-security profile vs a benchmark, see https://www.tigzig.com/apis/qrep; for a multi-ticker performance report, see https://www.tigzig.com/apis/ffn.
