VectorBT, Backtrader, Zipline, and Bt are free and open source, but they are libraries rather than products: they require Python and self-hosting, and none of them ship a chart. TradeGrub runs the same class of backtest in the browser.

No. The backtester runs in the browser with nothing to install and no environment to maintain. Strategies can be written in Python, in a Pine-compatible dialect, or built with no code at all in the visual strategy builder.
Yes. Portfolio tracking, a rebalancer, a correlation matrix, risk analysis, and P and L tracking all ship, so allocation strategies can be tested and then run rather than only measured.
Yes. The free tier includes all 306 indicators, 87 drawing tools, 96 pattern detectors, unlimited alerts, and backtesting, with no ads and no per-chart indicator caps. Pro at $5.99 per month, or $4.99 billed yearly, adds the TradeGrub data feed, cloud sync, and server-side alert evaluation.
