Research platforms (often called stock analysis websites) help you understand one company: ratings, fair value estimates, financials and analysis. This list only includes tools whose ratings or fair value features are confirmed on their official pages.
Each tool gets an overall score out of 5 from 4 sub-scores: research depth (45%), features and data (20%), value for money (15%) and ease of use (20%). Facts come from official pages. We only use facts we could confirm there. The order updates when prices or features change.
Some links on this page are affiliate links. If you subscribe through them we may earn a commission, at no extra cost to you. We score every tool on the same published criteria, using facts from official pages and our own testing. How we make money. This page is general information, not personal investment advice.

How we score
4 sub-scores with published weights. 3 use a fixed rule on facts from official pages; ease of use is our rating, updated when we test the tool. Full methodology.
Original insight rather than republished data: its own ratings or scores, its own fair value or valuation model, original written analysis or analyst coverage, and years of financial history.
Rule: 4): score = 1 + 4 x (points / 6). Tools that mainly republish other providers' data or analyst forecasts score lower.
The capabilities this job needs, as confirmed on official pages.
Rule: Counts ratings or fair value, screener, charts, alerts, portfolio tracking, data export: score = 1 + 4 x (confirmed / 6).
What the cheapest paid plan costs, and whether you can try it free or get a refund.
Rule: 60% price (Cheapest paid plan at its lowest list price per month (yearly billing if offered, intro offers ignored): USD 10 or less = 5, up to 20 = 4, up to 35 = 3, up to 60 = 2, over 60 = 1) and 40% free plan, trial or refund (Free plan plus free trial of a paid plan = 5, free plan only = 4, no free plan but a free trial or money-back guarantee = 2, neither = 1).
