How we grade them
| 3.0GPAFullstoryVery good | 2.2GPAHeapFair | |
|---|---|---|
| Value for money | AA site with 10,000 visitors a month fits comfortably in the free plan's 30,000 sessions, so the figure is $0, with 12 months of data and 10 users. Graded against LogRocket and Contentsquare, that's a lot for free. Paid plans are all quoted by sales. | CNo published figure for this size. A site with 10,000 visitors makes at least 10,000 sessions, the free cap, so you'd tip into Growth, which is only quoted after you install the snippet. Pro and Premier go through sales. No price, so a C. |
| 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. | CFree up to 10,000 sessions a month, with core charts, SSO and 6 months of history. Past the cap your data keeps arriving, but you can't see it until you upgrade. There's a trial too, though its length isn't stated. |
| Features | BReplays with developer tools, heatmaps, rage-click signals, funnels, journeys and retention, all from automatic capture, plus strong privacy controls. That's the whole replay and analytics job. Mobile capture and in-app surveys are add-ons on paid plans. | CAutocapture, funnels, journeys, retention and segments, with the Sense AI assistant from Growth up. Graded against Amplitude, Mixpanel and PostHog, which include replays even free, here replays and heatmaps are an add-on for Pro and Premier only. |
| Ease of use | CNo rating on record. Capture is automatic once the snippet's in, and replays make sense straight away, but there's a lot of platform behind them: segments, funnels and journeys take some learning. | CNo rating on record. Not having to tag events up front is a real head start, but you still define events afterwards and learn the charts, and paid plans start with a sales conversation. |
| 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. | BWeb only, with no desktop or phone app. It connects to Salesforce, Snowflake, Segment, Shopify, Iterable, Klaviyo and Marketo, and Heap Connect sends data to your warehouse on Pro and Premier. |
