Updated August 18, 2026. Quick answer: four fund and ETF screeners were free to use, with no account, on the day this page was written — Portfolio Visualizer, ETF Database, Yahoo Finance and Finviz. What the paid tiers mostly buy is depth of history and number of saved screens, not a better answer to “which fund should I hold”. The one genuinely expensive thing in this market is the mutual fund screener specifically: at Koyfin it does not appear until the Advisor Core tier at $209/month, more than five times the price of the tier that screens stocks and ETFs.
What’s actually free, checked today
Each of these returned a working screener over plain HTTP on 2026-08-18 with no login wall in the response. That is the test this page uses for the word “free”: not a free trial, and not a free account tier that hides the tool — the screener itself answered.
| Tool | What is free | Price the vendor shows | In the vendor’s words |
|---|---|---|---|
| Portfolio Visualizer | Fund Screener | Free | Personal and Educational Use No Login Required |
| ETF Database | ETF screener | Free | Served without an account when we checked it |
| Yahoo Finance | Equity/fund screener | Free | Served without an account when we checked it |
| Finviz | Stock and ETF screener | Free | Free tier served without an account; the Elite tier is the paid one |
| Koyfin | 2 screens on the free tier | $0/month | Free tier: 2Y financials & 1Y estimates |
Portfolio Visualizer is the outlier worth knowing about, because its free tier is labelled “Free Personal and Educational Use No Login Required” — no account at all. It does publish the limit: free tier supports portfolios with up to 15 assets with limited history and excludes the current month-to-date results. That limit is about saved portfolios rather than about screening, which is why the screener is usable without signing up.
What the paid tiers cost, in each vendor’s own words
Billing cadence is quoted exactly as each vendor states it, because a bare “$39 a month” is not a price when it is only available billed a year at a time. Koyfin’s figures below are the ones shown with its annual plan selected (Annual Save up to 30% with an annual plan).
| Plan | Price shown | Billing cadence | What that tier adds |
|---|---|---|---|
| Portfolio Visualizer Basic | $30/ month | Billed Annually | Personal and Educational Use |
| Portfolio Visualizer Pro | $55/ month | Billed Annually | Personal and Commercial Use |
| Koyfin Plus | $39/month | Annual plan selected | Stock & ETF screener |
| Koyfin Premium | $79/month | Annual plan selected | ETF valuation |
| Koyfin Advisor Core | $209/month | Annual plan selected | Mutual fund screener |
| Stock Rover Premium | $29/mo | Billed annually at $348/yr | Over 8,500 stocks, 7,000+ ETFs & 40,000+ funds |
The mutual fund screener is the expensive one
This is the finding most roundups miss, and it is visible on Koyfin’s own pricing page. Its Plus tier at $39/month lists Stock & ETF screener. The mutual fund screener is not in that tier, nor in Premium at $79/month. It appears in Advisor Core at $209/month, a tier the vendor describes as being for advisors. At that rate twelve months comes to $2,508 — our arithmetic, not a figure Koyfin quotes.
The practical reading for an individual investor: if you are screening ETFs you are well served free or cheaply. If you specifically need to screen open-end mutual funds on many criteria at once, the tools price you as a professional. Stock Rover is the exception at the individual end — its entry tier is quoted at “$29/mo”, “Billed annually at $348/yr”, and it states coverage of “Over 8,500 stocks, 7,000+ ETFs & 40,000+ funds”.
What a screener cannot tell you
A screener filters. It does not judge. Every tool above will happily return a list of funds sorted by past return, and that list is the single most misleading output in retail investing. None of these tools knows your tax situation, what you already hold, or when you need the money. If you want the ratings layer explained rather than the filtering layer, we have written that up separately: how fund ratings make money, why a stock star rating and a fund star rating are not the same thing, and how to research an ETF.
One well-known name is missing, and here is exactly why. Morningstar’s own pricing pages did not load for us on 2026-08-18: every attempt came back empty. Its definitions pages served normally the same hour, so this is that vendor blocking those particular paths rather than a fault at our end. The rule this page runs on is that a price is only publishable if the vendor published it and we read it today — so Morningstar is named here and left out of the tables, instead of being listed at a price we could not check. The paths tried:
- https://www.morningstar.com/products/investor
- https://www.morningstar.com/products/investor/pricing
- https://www.morningstar.com/lp/investor-free-trial
No affiliate link on this page, deliberately. We do have a paid relationship with one research provider elsewhere on this site. A page that ranks free tools against paid ones cannot also be paid to prefer one of them, so this page carries no partner link at all and nothing below moves on who pays us.
Screening individual stocks rather than funds, and living off the portfolio? That is a different filter set: stock screeners for retirees. The wider map is research it yourself.

Every price on this page was fetched from the vendor’s own site on 2026-08-18 and is quoted in the vendor’s own words, billing cadence included. Prices change without notice; where a vendor does not publish a figure, this page says so rather than filling the gap. Any number described below as our arithmetic is ours, not a price the vendor quotes.
