How we grade them
| 3.0GPAAmplitudeVery good | 3.0GPAFullstoryVery good | |
|---|---|---|
| Value for money | AA site with 10,000 visitors a month fits easily in the free plan's 2M events, so the figure here is $0, with unlimited seats and 10,000 replays included. Past 2M you move to Plus, $900 a year for up to 3M events. | 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. |
| Free plan and trial | BFree with no time limit and no card: 2M events, unlimited seats and 10,000 replays a month. You'll feel the edges, though. Only 10 saved charts, 1 experiment and 1 guide or survey live at once, and 1 year of data. | 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. |
| Features | BFunnels, retention, cohorts, replays, feature flags, web A/B tests, in-app guides and surveys, all from one vendor. That's the whole product analytics job and then some. Experiment results and SSO need Growth, though, which is sold through sales. | 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. |
| Ease of use | CNo rating on record. Autocapture gets data flowing, but useful funnels and cohorts mean planning your events and learning how the charts work. The AI agents on every plan help with the asking. | 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. |
| Platforms and integrations | BWeb only, with no desktop or phone app, which keeps it off an A. It connects to Segment, Braze, HubSpot, Snowflake, BigQuery, Databricks, Google Ads and Slack, and an MCP server lets Claude and Cursor query your data. | 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. |
| Best for | product analytics that stays free for a long while | seeing exactly what a user did |

Worth knowing
Amplitude
- Plus has no price list in text: it is free to 2M events a month, then billed by volume, and the pricing page's chart is the only published figure.
- Experiment results, A/B/n testing for feature flags and SSO start on Growth, which is priced through sales.
- Session replays are kept for 1 month on every plan; longer retention is an add-on for Growth and Enterprise.
- Free keeps 1 year of data and 10 saved charts; Plus keeps 2 years.
Fullstory
- No paid prices are published: Business, Advanced and Enterprise are all quoted through sales.
- Mobile app capture and in-app guides and surveys are add-ons on every paid plan.
- The free plan stops at 30,000 sessions a month and 10 users, and leaves out dashboards and StoryAI.
