MesoSim vs Portfolio Visualizer
Trying to decide between MesoSim and Portfolio Visualizer? Here's how they compare on pricing, features, and platforms — and which one fits the way you invest.
MesoSim
Best for options & derivatives and paper trading
Options strategy backtesting SaaS with low-code strategy definitions, observability (events log), risk graphs/Greeks, margin reporting, an options valuation model/solver, and an implied-volatility surface viewer. Plan gating: current onboarding starts with a one-time $25 trial fee for 14 days of Advanced + MesoLive access; canceling later leaves a limited free account. Standard is shown at $100/mo monthly and unlocks unlimited SPX + BTCUSD/ETHUSD options backtests, AI-assisted strategy development, sharing/exports and 1 MesoLive paper-trading account; Advanced is shown at $125/mo monthly and adds RUT/VIX/GLD, margin models, vol surface/HD risk graphs, and hourly risk traces (plus up to 2 paper accounts). Live trade execution is a paid MesoLive add-on; API access is FundPro-only.
Portfolio Visualizer
Best for monte carlo and correlation
Web-based portfolio analysis and reporting toolset covering backtesting, Monte Carlo simulation, tactical asset allocation, and optimization. The current homepage positions the product around portfolio analysis plus AI-explained insights, but core public tools remain backtesting, optimization, simulation, factor analysis, correlations, and fund analytics. Plan gating: Free tier is limited (e.g., portfolios up to 15 assets, limited history, and no current-year/YTD results). Basic and Pro are billed annually, support up to 150 assets with YTD results, and add save/import + export features; Pro is described for personal + commercial use.
