Best free ETF research and screening
ETF.com has the best free ETF database you'll find. The fund profiles are detailed, the comparison tools work well, and you get flow data that's usually locked behind paywalls elsewhere. The ads are annoying, but the data is worth it.
Pros
- Comprehensive free ETF database
- Detailed fund profiles with holdings and flow data
- ETF comparison tool for side-by-side analysis
Cons
- Interface is cluttered with ads
- Some advanced data behind paywall
- No portfolio integration

Morningstar
Free (basic) / $34.95/mo (Premium)
Best for in-depth ETF analysis with professional ratings
Morningstar has been analyzing funds for decades, and it shows. Their star ratings and analyst reports are the gold standard. The X-ray tool is especially useful—it reveals what you actually own underneath all your fund holdings.
Pros
- Trusted analyst ratings and reports
- X-ray tool reveals true underlying exposure
- Covers ETFs, mutual funds, and stocks in one tool
Cons
- Premium subscription required for best features ($34.95/mo)
- Can feel overwhelming for casual investors
- Interface is dated compared to newer tools
3
VettaFi (ETF Database)
Free (core) / Premium available
Best for finding thematic and sector-specific ETFs
If you're looking for ETFs around a specific theme or sector, VettaFi is your best bet. Their categorization is excellent, and the head-to-head comparison tools make it easy to pick between similar funds.
Pros
- Excellent thematic ETF categorization
- Head-to-head ETF comparison tools
- Free access to core screening features
Cons
- Less depth on individual fund analysis than Morningstar
- No portfolio tracking or integration
- Premium data requires subscription
4
Fidelity ETF Screener
Free (with Fidelity account)
Best built-in screener for Fidelity customers
If you already have a Fidelity account, their built-in screener is surprisingly good. You get ESG scoring, tax efficiency metrics, and sector breakdowns—all free, no extra subscription needed. The catch is it only makes sense if you trade through Fidelity.
Pros
- Free for Fidelity customers
- ESG scoring and tax efficiency metrics
- Integrated with Fidelity trading platform
Cons
- Requires Fidelity account for access
- Only useful if you trade through Fidelity
- No API or export for use in other tools
5
Clarity (for tracking ETF holdings)(Our Pick)
$99/year
Best for tracking ETF holdings after screening and purchasing
Clarity won't help you find ETFs, but once you've bought them, it tracks your holdings across brokerages and shows you how everything is performing together. Pair it with a screener and you've got the full workflow covered.
Pros
- Tracks ETF holdings across multiple brokerages
- Performance comparison across all holdings
- AI assistant provides allocation insights
Cons
- Not a screening or research tool
- No fundamental ETF data or ratings
- Best used alongside a dedicated screener
