What It Is

invested.fyi appears, based on the scraped content, to be an “Auto-Investing Simulator.” Its core purpose is to answer questions such as: if you had bought assets like TSLA, GME, Bitcoin, or Dogecoin early and held them long term—or invested automatically every week—how would your principal and returns have changed historically? It is more of a web-based calculator for individual investors than a typical developer platform.

Core Features and Coverage

The tool provides inputs such as asset selection, start year, end year, initial principal, weekly recurring investment amount, and weekly investment day, then generates portfolio results. Outputs include total principal invested, shares/units held, cost basis, ending portfolio value, absolute profit, total return, and annualized return. Assets listed in the scraped text include VTSAX, Bitcoin, Dogecoin, Ethereum, GameStop, Tesla, Amazon, Apple, Facebook, Google, Netflix, Snap, NIO, Palantir, Zoom, and others, with some marked as EOD price adjusted.

Developer Tooling Perspective

From the available page content, there is no evidence of support for programming languages, frameworks, APIs, SDKs, webhooks, data export, command-line tools, or third-party integrations, so it is weak from a developer-tooling standpoint. There is also no indication of whether it is open source, supports self-hosting, has a GitHub repository, or provides deployment documentation. In terms of documentation quality, the page itself has clear form inputs and result fields, but lacks explanations of calculation methodology, data sources, adjustment methods, fee/tax assumptions, and similar details.

Pricing and Ease of Use

The scraped content does not mention pricing, subscriptions, paywalls, or payment methods. Ease of use is its main strength: users only need to choose an asset and parameters to generate portfolio performance, making it suitable for quickly getting an intuitive sense of historical recurring investment results. However, because methodology disclosure is limited, the results are better treated as a rough reference rather than a basis for serious investment research or programmatic backtesting.

Pros, Cons, and Who It’s For

Its advantages are that it is lightweight, simple to use, covers popular stocks and crypto assets, and can show performance through periods such as the 2007 financial crisis or the COVID crash. Its drawbacks are the limited asset coverage and the lack of arbitrary ticker input, APIs, batch analysis, export features, and verifiable data sources. It is suitable for individual investors, personal finance content creators, or users who want to quickly explain “what would have happened if you had DCA’d into a certain asset back then.” It is less suitable for developers who need auditable data, automation integrations, or professional quantitative backtesting.

Access from China

The scraped text does not provide information about access from mainland China, payment support, or ICP filing status, so china_access can only be considered unknown. If access is unstable, alternatives such as Portfolio Visualizer, TradingView, Yahoo Finance, or local recurring-investment return calculators may be worth considering.
