How we grade them
| 3.0GPAFullstoryVery good | 1.6GPAQuantum MetricWeak | |
|---|---|---|
| Value for money | AGraded against LogRocket and Contentsquare. A site with 10,000 visitors a month fits in the free plan's 30,000 sessions, so the figure is $0, with 12 months of data and 10 users. Paid plans are all quoted by sales. | CNo prices are published. Plans are custom and priced by digital properties, session volume and support level. |
| Free plan and trial | BFullstoryFree needs no card: 30,000 sessions a month, 12 months of data, replays, basic analytics and debugging for up to 10 users. Dashboards and StoryAI aren't included, and there's no free way past 30,000. | FThe pricing page names no free plan and no self-serve trial. |
| Features | BReplays with developer tools, heatmaps, rage-click signals, funnels, journeys and retention, all from automatic capture, with sensitive data left out by default. That's the whole replay and analytics job. Mobile capture and in-app surveys are add-ons on paid plans. | CReplay and summaries, an AI assistant, journeys, monitoring and alerts, an MCP server. Data streaming and contact-center modules are paid add-ons. |
| Ease of use | CNo rating on record. Capture is automatic once the snippet's in, but there's a lot of platform behind the replays: segments, funnels and journeys take some learning. | CNo store rating on record. A quoted enterprise platform comes with onboarding and a learning curve. |
| Platforms and integrations | BWeb only, no desktop or phone app of its own. It connects to Google Analytics, Shopify, Salesforce, Zendesk, Intercom, Jira, Slack and Twilio Segment, with warehouse sync as a paid add-on. | CWeb only, and the listing names no integrations beyond a partners page. |
| Best for | seeing exactly what a user did | enterprise session replay and journeys |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
