Portfolio Visualizer is a web-based portfolio analysis suite for backtesting portfolios, testing asset allocations, running Monte Carlo simulations, optimizing allocations, analyzing factors, checking correlations, and researching funds. It is strongest for DIY investors, analysts, and advisors who want evidence for allocation, withdrawal, and risk decisions without building every model in spreadsheets. The free tier is useful but constrained, while Basic and Pro add larger portfolios, YTD results, saving, imports, exports, and commercial-use support on Pro. It is not a broker, live portfolio accounting system, or automatic rebalancing platform.

FX Replay is a browser-based manual backtesting and bar-replay platform for traders practicing forex, futures, crypto, commodities, and related multi-asset setups. It is strongest for discretionary strategy practice: replay sessions, multi-chart layouts, multi-pair testing, journaling, checklists, Monte Carlo, risk-reward simulation, CSV imports, and economic-calendar context help traders review execution without connecting a live broker. It is not an automated strategy engine, and seconds-level data plus broader asset coverage are Pro-gated.

Starred Tools
These are my top picks. Tools I've tested thoroughly and found to be excellent. They do their job really well, and I use them a lot. If you're not already familiar with them, I highly recommend checking them out.
Tested Tools
These are tools I've tried and found to be solid, but not standout. Think of them as passing an initial quality screen: worth exploring, though not all will be exceptional.
Curation & Accuracy
This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).
Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
