Alphasim is a minimalist backtester inspired by https://github.com/Robot-Wealth/rsims.
The backtest input is the natural output of a typical quant research process: a dataframe of asset prices and weights.
Strategy performance is optimised using a trade buffer heuristic.
If you're looking for a more traditional backtester and algo development platform (in Go) check out my other project https://github.com/thecolngroup/alphakit.
