Koyfin Alternatives Where the Custom Index Is the Hero
Koyfin is an excellent research terminal. It packs deep fundamentals, charts, screeners, macro data, and watchlists into one place, and many serious investors use it as their daily research home. It is a broad tool, and that breadth is its strength. The custom index is possible inside it, but it lives as a buried side-feature rather than the main event. Indexes flips that emphasis. The named custom index is the hero object of the whole product: you build a weighted basket from stocks and crypto, backtest it against real market history, and track it over time versus benchmarks like the S&P 500 and BTC. It is self-serve at a prosumer price and stays informational and educational, track-and-analyze not trade, with no brokerage and no trades.

In short
Koyfin is a broad research terminal: fundamentals, charts, screeners, macro data and watchlists in one place, and it is very good at that. Building a custom index is possible inside it, but it sits as a side-feature rather than the main event. Indexes is built around the opposite emphasis. The named, weighted index is the hero of the whole product: you construct it from stocks or crypto, backtest it against real market history, and keep it tracked against the S&P 500 or BTC over time. If you want an all-in-one research dashboard, Koyfin is deeper. If the custom index is the thing you actually care about, Indexes puts it at the center.

Questions
Koyfin and Indexes, answered
What is Koyfin used for?
Koyfin is a market research and analytics terminal. Investors use it for company fundamentals, charting, screening, macro and economic data, watchlists and dashboards, all in one browser-based tool. It is a broad research home rather than a purpose-built index construction tool, which is where it differs from Indexes.
Can you build a custom index in Koyfin?
You can assemble custom views and baskets in Koyfin, but the custom index is a side-feature inside a much larger research product rather than the main object. Indexes is built the other way around: authoring, weighting, backtesting and tracking a named index is the entire product, not one tab among many.
What is the best Koyfin alternative for building an index?
If your goal is specifically to construct and follow your own index, Indexes is the closer fit. You choose the members, set the weighting method, pick a rebalancing schedule, backtest the result against real market history, and track the level against the S&P 500 or BTC. It stays analysis-only, with no brokerage and no trades.
Does Indexes cover stocks and crypto like Koyfin?
Indexes lets you weight stocks and crypto together inside a single index and backtest the combined result, which most research terminals handle awkwardly if at all. It does not try to match Koyfin on breadth of research data. It is focused on one job: building, testing and tracking a custom weighted index.

Build your index and see how it backtests
Bundle stocks or crypto into your own weighted index, backtest it against real market history, and track it against the S&P 500 or BTC. Prosumer pricing, no brokerage account. Indexes is educational and informational only, and it never places a trade. Decide for yourself.
