Website/Tools to evaluate historic returns of specific stock/fund allocations

[ArkTinkerer]

Like the title says! I want to measure the relative perfomance of some accounts by seeing what the returns of various specific stock/mutual fund/etf distributions might be. I'm ok with doing them for a specific company--say picking all the mutual funds/etfs from Vanguard for example.

I'm trying to get a hard number comparing some managed accounts/funds compared to set it and rebalance yearly self management.

I thought EZbacktest was good but recently went from free to donation supported. The free versions probably still can be found.
