The honest comparison
Koyfin is the best value in the terminal-lite tier and deserves the reputation it has. Its dashboards are fast and genuinely well designed, the free plan is more generous than most paid products, and Plus at $39 per month adds 10-year financials, ETF holdings, and screening, while Premium at $79 per month brings advanced portfolio analytics and unlimited custom formulas. If you want Bloomberg-shaped fundamentals and charting without the Bloomberg invoice, Koyfin is the right buy and you should keep it. The boundary is that Koyfin is a surface for reading, not a bench for testing. It will show you a company's margins across a decade, its valuation against peers, and its estimate revisions, all beautifully. It will not take the sentence in your head, "quality compounders bought when the 200-day is rising", and tell you what that rule actually did across 20 years of real prices. That gap is where money is usually lost, because a thesis that looks perfectly reasonable on a dashboard can be one that history has quietly punished for two decades. Agenttrading fills exactly that gap. You type the thesis in plain English, the bench restates it as an explicit rule and shows it to you before running, tests it on 20+ years of split- and dividend-adjusted daily data with a 0.1% cost per trade assumed by default, plots it against buy-and-hold with the worst drawdown shaded, explains the risk in words rather than in ratios, and stamps an honest verdict: HELD UP, MIXED, or UNDERPERFORMED. Plans run $19 to $129 per month, there is no execution and no brokerage connection at any tier, and the losing verdict stays prominent because a bench that cannot say "this failed" is not a bench.

On the same bench
Data is where a test starts, not where it ends: historical stock data explains the adjusted 20-year record every run uses, and backtesting software shows what happens once a rule meets it. For fundamentals depth without the dashboard, fundamental analysis tool reads the filings, and portfolio backtesting handles whole baskets. Comparing several vendors at once is what the best AI trading software roundup is for, with the Seeking Alpha alternative covering the research-library option.
QUESTIONS - ASKED AND ANSWERED
Koyfin alternatives: the common questions
What is the best Koyfin alternative?
For the same job, a fundamentals and charting dashboard, the honest answers are TradingView for charts, stockanalysis.com for free fundamentals, and Morningstar for research depth. For a different job, deciding whether an idea you already hold is any good, you want a backtesting bench rather than another dashboard: Agenttrading tests a plain-English thesis on 20+ years of adjusted data from $19 per month and stamps an honest verdict.
How much does Koyfin cost?
Koyfin has a free plan, with Plus at $39 per month and Premium at $79 per month, and advisor plans at $209 and $299 per month; annual billing saves up to about 30%. Prices were checked on Koyfin's pricing page in July 2026 and vendors change them, so verify before you buy. Agenttrading starts at $19 per month and does a different job: testing, not dashboarding.
Is Koyfin free version good enough?
For a lot of investors, yes. The free plan covers charting, dashboards, watchlists, and 2 years of financials, which is more than many paid products give you. You outgrow it when you need 10-year financials, screening, or ETF holdings, which is the Plus tier at $39 per month. What no Koyfin tier does is backtest the rule you have in mind, so the free plan plus a bench is a common and cheap combination.
Can you backtest a strategy in Koyfin?
No. Koyfin is built for research and monitoring: dashboards, financials, estimates, screens, and portfolio analytics. It does not take a trading rule such as "hold above the 200-day" and run it across two decades of adjusted prices with trading costs charged. That is a separate category of tool, and it is the specific gap Agenttrading was built to fill, in plain English rather than in code.
Is Koyfin better than Bloomberg?
Different leagues, on purpose. Bloomberg is an institutional terminal costing well into five figures a year, with news, chat, fixed income, and execution built in. Koyfin covers the fundamentals and charting slice of that for $39 to $79 per month and is honest about the rest. For an individual investor or a small research team, the Koyfin tier is usually the right ceiling, and the money saved buys the testing tool that neither one includes.
