Amplitude vs Statsig
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Both sides assessedAmplitude compared with Statsig
Both combine analytics with experimentation, but from opposite directions. Statsig is an experimentation engine with strong statistics and a published $150 per month Pro plan; Amplitude is an analytics platform whose experiment layer is good enough for most teams and shares metric definitions with the charts. Take Statsig if experiment velocity and statistical rigour are the organising principle and engineers own the tooling; take Amplitude if analytics is the daily job and experiments happen weekly rather than hourly.
Statsig compared with Amplitude
Amplitude also bundles flags and experiments with analytics, but leads with analytics and sells upward into enterprise with quoted pricing above 70 million events. Statsig leads with experimentation, publishes a $150 Pro price, and gives away flag checks entirely. Choose Amplitude if product managers and marketers are the primary users and you want guides and surveys too; choose Statsig if engineers own the tooling and experiment rigour is the point.
Choose Amplitude if
Product-led software companies who want analytics, session replay, feature flags, experiments, and in-app guides from one vendor on an event meter rather than per seat, and who expect to stay under 70 million events a month where the self-serve Plus plan applies and no sales call is required.
Choose Statsig if
Engineering-led product teams who ship behind flags and want experimentation with real statistical rigour, plus analytics and session replay on the same event data, at a published $150 a month rather than a negotiated enterprise contract.
Side by side
13 attributes| Attribute | Amplitude | Statsig |
|---|---|---|
| Category | Product Analytics | Product Analytics |
| Starting price | $0 (Free, 2M events per month forever); Plus starts at $0 with the first 2M events free (free plan available) | $0 (Developer), then $150 per month (Pro) (free plan available) |
| Pricing model | Usage-based on events ingested per month across four plans. Free and Plus are self-serve with published limits, Growth and Enterprise are quoted, and add-ons on the upper tiers are priced as a percentage of the platform plan. | Usage-based on analytics events with unlimited free feature flag and config checks on every tier. Three plans: a free Developer tier, a published Pro tier at $150 per month, and quoted Enterprise contracts that can be event-based or experiment-based. |
| Free plan | 2 million events per month forever with no credit card, including 10,000 monthly session replays and 500 active AI visibility prompts. Behavioural cohorts are not included on the free tier. | Developer includes 2 million analytics events per month, unlimited feature flag and config checks, and 50,000 session replays per month, with no credit card required. |
| Free trial | No fixed trial; the permanent free plan is the evaluation path, and paid features can be trialled within it | No separate trial; the free Developer plan is permanent and requires no credit card |
| Best for | Product-led software companies who want analytics, session replay, feature flags, experiments, and in-app guides from one vendor on an event meter rather than per seat, and who expect to stay under 70 million events a month where the self-serve Plus plan applies and no sales call is required. | Engineering-led product teams who ship behind flags and want experimentation with real statistical rigour, plus analytics and session replay on the same event data, at a published $150 a month rather than a negotiated enterprise contract. |
| Setup time | A working chart in under an hour with autocapture or a CDP connection. A properly instrumented, governed implementation across web and mobile is a two to four week project, longer than Mixpanel because there is more platform to configure and because tracking plans are worth doing properly from the start. | An hour to the first feature gate, because SDK installation and a boolean check is genuinely quick. A day or two to a first meaningful experiment, because that requires defining metrics you trust. Warehouse-native deployment is a multi-week data engineering project rather than an installation. |
| Learning curve | Moderate. Chart building is approachable, but the platform rewards understanding behavioural cohorts, tracking plans, and how experiments read metrics, and none of that is obvious on day one. Expect a designated owner rather than assuming everyone will self-serve. | Steepest in this batch, and deliberately so. The flag interface is simple, but using the platform well requires understanding metric definitions, exposure logging, variance reduction, and when a result is real. Teams without anyone who cares about that will use ten percent of what they are given. |

Strengths and limitations
Amplitude
Strengths
- The broadest self-serve platform in the category: analytics, session replay, feature flags, experiments, guides, surveys, and a CDP layer under one event meter.
- A permanent free plan of 2 million events a month including 10,000 session replays, and a self-serve Plus tier that stretches to 70 million events before any sales involvement.
- Behavioural cohorts are a first-class shared object rather than a per-report filter, so one definition drives charts, experiments, guides, and outbound audiences.
- Feature flags are included from the Plus tier rather than gated behind enterprise, which is unusually generous packaging.
Limitations
- Above 70 million events a month, pricing goes dark. Growth and Enterprise are quoted, and add-ons priced as a percentage of the platform plan make the cost curve steeper than it looks.
- Behavioural cohorts are excluded from the free plan and capped at 20 on Plus, which is a meaningful limit given that cohorts are the mechanism everything else depends on.
- The platform is large and there is more configuration surface than a small team needs; the tool is genuinely harder to learn than Mixpanel for a non-technical user.
- Hosted only. There is no open source edition and no self-hosted deployment, so teams with a hard requirement to keep behavioural data inside their own infrastructure are out.
Statsig
Strengths
- Unlimited free feature flag and dynamic config checks on every tier, which removes the metering anxiety that stops teams from flagging everything.
- A published $150 per month Pro price with a published $0.05 per 1,000 event overage rate, in a category where most competitors above the free tier require a quote.
- Serious experimentation statistics (CUPED variance reduction, sequential testing, holdout groups) available on the free tier, not gated behind an enterprise contract.
- The most generous session replay allowance among analytics-first vendors: 50,000 replays a month free and 100,000 on Pro.
Limitations
- Owned by OpenAI since September 2025. The company says Statsig continues to operate independently from Seattle, but the founder now runs product engineering at OpenAI and the strategic commitment to a third-party SaaS is unproven over a long horizon.
- Engineer-first by design. The interface expects fluency in metric definitions and experiment methodology, and non-technical staff will not self-serve the way they do in Mixpanel.
- Session replay is web-centric and built on rrweb; there is no mobile replay story comparable to Mixpanel's or Amplitude's iOS, Android, and React Native capture.
- The analytics are adequate rather than excellent. If experimentation is not part of your practice, you are buying a mediocre analytics tool at a good price rather than a good tool.

Amplitude's value depends almost entirely on whether you use the platform or only the charts. At 10,000 monthly users generating perhaps 300,000 events, the free plan covers you with replays included, which makes Amplitude one of the cheapest ways to run real product analytics at small scale. At 100,000 monthly users on disciplined instrumentation, roughly 3 million events, you are on Plus and paying tens of dollars a month rather than hundreds, which is aggressive pricing for what you get. If you also retire a feature-flag subscription, an onboarding tool, and a survey widget, the effective value is very strong. If you use Amplitude purely as a charting tool, you are paying platform complexity for chart value, and Mixpanel or PostHog will feel lighter. The risk sits above 70 million events, where published pricing disappears and you are negotiating with a public company that has enterprise revenue targets.
Statsig
Usage-based on analytics events with unlimited free feature flag and config checks on every tier. Three plans: a free Developer tier, a published Pro tier at $150 per month, and quoted Enterprise contracts that can be event-based or experiment-based.
- Developer$0
- Pro$150

Statsig is the best price per unit of capability in this category, provided you can use the capability. At 10,000 monthly users the free Developer plan is not a teaser: 2 million events, unlimited flag checks, 50,000 replays, and the complete experimentation engine including CUPED and sequential testing costs nothing. At 100,000 monthly users with disciplined instrumentation you are around 3 to 5 million events, which lands squarely inside the $150 Pro plan with 100,000 replays included. Compare that with buying a feature flag service, an analytics tool, and a replay tool separately at that scale and Statsig is roughly a third of the cost. The value collapses if you do not ship behind flags or lack the traffic to conclude experiments, because then you are paying for an experimentation platform to be a mediocre analytics tool.
Editorial verdict on each
Amplitude
Category LeaderAmplitude is the most platform you can buy in this category without a sales call, and for a product-led company that would otherwise be paying for analytics, feature flags, an onboarding tool, and a survey widget separately, that consolidation is the whole argument. The free tier is real, Plus stretches to 70 million events self-serve, and feature flags being included at that level is genuinely generous packaging. Buy it if you will use the platform, not just the charts, and if you have someone willing to own tracking plans and cohort definitions. Look elsewhere if you want the lightest possible tool (Mixpanel), if you want to self-host (PostHog or Matomo), or if you can foresee crossing 70 million events, because that is where published pricing ends and enterprise negotiation begins.

MomentumStatsig gives away the thing everyone else meters. Unlimited free feature flag checks, the complete experimentation engine including CUPED and sequential testing on the free tier, 50,000 free session replays a month, and a published $150 Pro plan add up to the best capability per dollar in this category by a comfortable margin. Buy it if engineers own your tooling, you ship behind flags, and you have enough traffic for experiments to conclude. Do not buy it as a general-purpose analytics tool for a non-technical team, and do go in aware that the company now belongs to OpenAI. If that ownership worries you, warehouse-native deployment is a genuine answer rather than a talking point, because in that mode the data and the definitions were never theirs to keep.
