Portfolio Visualizer

DetailsVisit site

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.

Zenvesto

DetailsVisit site

Zenvesto is a web-based stock, ETF, crypto, and benchmark portfolio tracker built around dashboards, watchlists, performance metrics, portfolio health scoring, AI-powered insights, market news, earnings calendars, CSV imports, and historical simulation. It fits stock portfolio tracker and AI portfolio tracker intent, but current public evidence supports conservative U.S. exchange coverage, finite plan limits, and manual or CSV workflows rather than broker sync. It is useful when a modern dashboard and guided analysis matter more than tax-grade accounting or execution. It is not a broker, public API today, custodian sync product, wash-sale engine, or professional portfolio accounting system.

TipRanks

TipRanks is an investment research platform built around analyst ratings, price targets, expert rankings, Smart Score, AI stock analysis, news sentiment, insider signals, hedge-fund activity, and portfolio tools. It is strongest for investors who want to compare market opinions and stock forecasts quickly, with Premium and Ultimate unlocking more of the expert, portfolio, export, and AI workflow.

FX Replay

DetailsVisit site

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.

ETFdb ETF Screener

DetailsVisit site

ETFdb ETF Screener is a VettaFi ETF database and screener for U.S.-listed ETFs and ETPs, with filters for returns, flows, expenses, ESG, dividends, risk, holdings, taxes, technicals, and ratings. It is useful when ETF selection needs structured screening and exportable results.

Marketlog

DetailsVisit site

Marketlog is a web and mobile portfolio tracker for retail investors and active traders who want manual or broker-connected portfolios, dividend tracking, goals, target allocation, benchmarking, forecasts, alerts, market pages, calendars, and public or private portfolio sharing. It is useful for monitoring holdings and portfolio behavior across asset types, especially when users want mobile access and community portfolio browsing. It is not a broker, exchange, fiduciary, investment adviser, or public market-data API.

okama

DetailsVisit site

okama is a free open-source portfolio analytics toolkit with web widgets, a REST API, and a Python library for efficient frontiers, risk metrics, Monte Carlo simulations, cash-flow modeling, and historical market or macro data. It is best for technical users who want reproducible analysis rather than a consumer portfolio tracker.

Sharesight

DetailsVisit site

Sharesight is a global portfolio, dividend, performance, and tax-reporting tracker for DIY investors, accountants, advisers, and family offices. It is built for keeping investment records and reports across brokers and asset types, not for placing trades, running intraday trading dashboards, or replacing a tax professional in complex filings.

The Ledger Terminal

DetailsVisit site

The Ledger Terminal is a web-based fundamental stock research terminal built around one-page U.S. stock tearsheets, valuation charts, quality checks, screeners, comparisons, and SEC-linked financial history. It is aimed at long-term business analysis, not trading execution or portfolio accounting.

Total Real Returns

DetailsVisit site

Total Real Returns is a free web tool for charting real purchasing-power returns and nominal total returns with dividends reinvested. It is strongest for investors who want a fast visual answer to how stocks, ETFs, mutual funds, or cash-like series performed after inflation instead of only seeing price charts. The site provides return tables, drawdowns, normalization controls, and multi-symbol comparisons with end-of-day updates. It is intentionally narrow: not a screener, portfolio tracker, API, broker, or full research terminal.

Tradervue

DetailsVisit site

Tradervue is a mature trading journal for importing trades, reviewing charts, analyzing performance, sharing trades, working with mentors, and using reports across stocks, ETFs, futures, forex, and options. It is strongest for active traders who want post-trade analytics, broker sync or file imports, chart-based review, MFE/MAE analysis, R-based risk reporting, CSV exports, and a public REST API. Free access is useful for light journaling but capped at 30 grouped trades per month; Silver and Gold unlock the serious reporting and import workflows. Tradervue is not a broker, tax-lot accounting system, or market-discovery platform.
