Portfolio Visualizer Alternatives
We make one of these tools, so read this with that in mind. What follows is organised by what you were using Portfolio Visualizer for, and names the tool that wins each job. For most of these jobs, that is not us.
First: you may not need to leave
Most pages at this search treat Portfolio Visualizer as though it has become unusable. It has not. The free tier still needs no account and still runs portfolio backtesting, monte carlo simulation, portfolio optimization, factor regression, asset analytics, tactical allocation models.
What the free tier actually withholds is narrower than that:
- Portfolios limited to 15 assets, against 150 on the paid plans
- Limited history, in their own wording, where paid plans are not capped
- No current month-to-date results
- No saving or importing of portfolios, simulations or optimisations
- No Excel, CSV or PDF export
- No custom data series, management fees or saved capital market assumptions
If none of those bind on you, stop here. If the 15-asset cap is the problem, or you want history the free tier will not give you, or you have hit the wall on saving and exporting, the rest of this page is the field.
Matched to the job
Best for: Free backtesting over the longest possible history
The tool the Bogleheads and Reddit threads actually recommend when someone hits a wall at Portfolio Visualizer. Runs on daily data rather than monthly, so drawdowns and volatility are measured more finely, and its library of simulated funds extends real tickers backwards, letting a strategy be tested over decades the fund itself did not exist for. Its rebalancing sensitivity tool runs hundreds of backtests across different rebalancing rules at once, which nothing else does.
The catch: Built and maintained by one developer, and data accuracy has been a recurring topic in the forums, with a provider change discussed. Worth sanity-checking a result you intend to rely on.
Best for: Seeing how an allocation behaved across every possible start date
A set of charts rather than a calculator, and several of them exist nowhere else. The heat map shows compound growth for every combination of start and end year at once, so the good and bad stretches are visible rather than averaged away. Others cover the full spread of accumulation paths and worst-case withdrawal rates.
The catch: Asset classes rather than individual funds, and no optimiser. It is for understanding an allocation you already have in mind.
Best for: European investors holding UCITS funds
Backtesting built for the European index investor rather than adapted for them: everything priced in euro, and only funds actually available in Europe. If you have ever tried to model a portfolio of UCITS ETFs in a US tool, this solves the problem those tools create.
The catch: Backtesting only. No optimisation, and no forward-looking assumptions.
Best for: Retirement and cashflow planning rather than portfolio analysis
A life-planning tool with Monte Carlo simulation, cashflow projection and scenario modelling. It answers whether the plan works, not which allocation is best.
The catch: Tax optimisation, withdrawal strategies and downloadable reports are behind Premium. It is not a portfolio optimiser.
Best for: Factor regression, and optimisation objectives nothing else offers
Worth saying plainly on a page about leaving it: for factor regression there is no free alternative that comes close, and its free tier still runs backtests, Monte Carlo, optimisation and factor analysis without an account. If the 15-asset cap is not binding on you, you may not need to leave at all.
The catch: Free portfolios are capped at 15 assets, with limited history and no saving or export.
Best for: Deciding what to hold, when you do not have return assumptions of your own
Every other tool on this list asks what returns you expect, or answers with what happened in the past. This one supplies the forecasts: twenty houses' published capital market assumptions, switchable, so you can see how much your allocation depends on whose view you take. Optimisation includes hierarchical risk parity and Black-Litterman, Bitcoin is a first-class asset class with its own assumptions, and history reaches back to 1970.
The catch: Asset classes rather than individual tickers, five optimisation objectives rather than fifteen, and no factor regression. If you want to take a portfolio apart rather than decide on one, the tools above do it better.
What nothing free replaces
Factor regression. Portfolio Visualizer runs OLS and LASSO against Fama-French, AQR, Alpha Architect and q-Factor datasets, with CAPM through five-factor and quality models, and nothing on this list is a substitute. If that is what you were doing, the honest advice is to keep using it, on the free tier if 15 assets is enough and on a paid plan if it is not.
The same goes for its more unusual optimisation objectives. Conditional value-at-risk, Kelly criterion, Omega, Sortino and minimum maximum-drawdown are not offered by the free tools here, ours included.
The one thing none of them do
Every tool above, Portfolio Visualizer included, either asks what returns you expect or tells you what returns happened. None of them tells you what to expect. That gap is the reason we built Portfolio Lab: it loads the published capital market assumptions from twenty forecasting houses, and lets you switch between them to see how much your allocation depends on whose view you take. When BlackRock forecasts 7.7% for US large cap and GMO forecasts −4.0%, that is not a detail, and no backtest will tell you which to plan around.
Which is the honest summary of this page. If you are examining a portfolio you already hold, the tools above do it better than we do. If you are deciding what to hold, start with the assumptions, because everything else follows from them.
Free, no account, no asset cap.
