Statsig Pricing: Plans, Costs and What You Get

The quick answer

Quick answer: Statsig has three plans. Developer is free with no credit card and includes 2 million metered events a month, unlimited feature flag and config checks, 50,000 session replays and unlimited seats. Pro costs $150 a month with 5 million events included, then $0.05 per 1,000 extra events, plus 100,000 session replays and unlimited analytics retention. Enterprise is custom, with event or experiment based contracts and volume discounts. The bill is driven by metered events (exposures, logged events and metrics), not by seats or flag checks. Statsig is now part of Amplitude, and its pricing page still lists the same three plans as of November 2026.

Who owns Statsig now, and does it change the price?

Statsig's home page carries the line "Statsig is part of the Amplitude family". A note on Statsig's own blog says it was acquired by Amplitude on May 5, 2026, after an earlier agreement to join OpenAI in September 2025. The original team stayed at OpenAI, while the product, brand and customer base moved to Amplitude, which says it continues to develop Statsig.

For pricing, the practical points are:

• The plans are unchanged on the page. As of November 2026, Statsig's pricing page still shows Developer (free), Pro ($150 a month) and Enterprise (custom), billed on metered events.
• The products are being connected. In a June 2026 update on its blog, Statsig said Amplitude events and cohorts would work inside Statsig and Statsig experiment results would show up inside Amplitude, so customers of both can use them together.
• No price change was announced on the Statsig pages we read. If you are signing a multi-year Enterprise contract, ask how pricing will work once the two products are combined.

Statsig plans compared

Developer plan (free)

Every new account starts on Developer. It includes 2 million metered events each calendar month at no charge, unlimited flag and config checks, and 50,000 session replays a month. You get A/B tests and experimentation, feature flags and config management, product and web analytics with 1 year of retention, session replays kept for 30 days and unlimited seats. Support is through the Statsig Slack community.

If you go over 2 million events, Statsig prompts you to add a card and move to Pro. If you stay on Developer, flag and config targeting keep working, but Metric Lift calculations (the impact numbers on your flags and experiments) stop until the next month. Statsig says it sends several warnings first.

Pro plan ($150 a month)

Pro costs a base fee of $150 a month, charged at the start of each billing period. It includes 5 million metered events, and each extra 1,000 events costs $0.05. Overages from one month are added to the next month's bill.

On top of Developer, Pro adds advanced experimentation, advanced product analytics, unlimited analytics retention, change reviews and approvals, API controls and 100,000 session replays a month.

One detail catches teams out: each Pro subscription covers one project. You can create more projects, but each one is upgraded separately. Multiple projects under one account are an Enterprise feature.

Enterprise plan (custom)

Enterprise has no public price. Statsig lists event based or experiment based contracts, large volume discounts and the option to run Statsig warehouse native, inside Snowflake, Databricks, BigQuery, Redshift, Athena or Fabric. It also adds outgoing data integrations, data warehouse imports, SSO with role-based access and teams, priority support with a 4 business hour response, custom session replay retention and HIPAA eligibility with a signed BAA. Statsig sells product analytics on its own only at this tier.

What drives the Statsig bill

Statsig bills on metered events, not on seats or on how often your code checks a flag. Its pricing FAQ lists four kinds:

• Exposures: when your app asks the SDK whether a user is in an experiment, or in a feature flag that has Metric Lifts turned on.
• Log events: events your app sends through the SDK, or events imported from a third-party source such as Segment.
• Ingested metrics: pre-computed metrics loaded from a data warehouse.
• Custom metrics: when existing events or metrics are combined into a new custom metric.

A few rules lower the count. Exposures for the same user and the same flag or experiment are deduplicated over 60 minutes on client SDKs and 1 minute on server SDKs. Experiments that have not started or have finished, and flags that are disabled, do not create metered events. By default there is no charge for exposures on flags rolled out to 0% or 100%. Each logged event can carry one extra dimension for free; every additional dimension counts as another log event.

Usage is shown under Project Settings, in the "Usage & Billing" tab of the Statsig console.

Worked example: a Pro bill

This example uses only Statsig's published Pro prices. It is not a typical customer.

A team on Pro sends 12 million metered events in a month.

• Included: 5 million events.
• Overage: 12M minus 5M = 7M events, which is 7,000 blocks of 1,000.
• Overage cost: 7,000 x $0.05 = $350.
• Total for that month's usage: $150 base + $350 overage = $500, with the $350 arriving on the following month's bill.

At 30 million events the overage is 25,000 x $0.05 = $1,250, so the month costs $1,400. For bills like that, Statsig's FAQ points to Enterprise volume discounts.

How to keep the cost down

These tips come from how Statsig itself describes billing:

• Turn Metric Lifts off on flags that do not need impact numbers. Statsig only charges flag exposures when Metric Lifts are on and the flag is a partial rollout.
• Clean up finished work. Disabled flags and experiments that have ended stop generating metered events.
• Watch extra dimensions. Each dimension beyond the first one on a log event is billed as another event.
• Prefer client SDK checks where it fits. Client SDKs deduplicate exposures over a 60 minute window, server SDKs over 1 minute.
• Check usage mid-month in Usage & Billing, so a busy launch does not surprise you on the next invoice.
• Ask about Enterprise volume pricing once overages pass the base fee several times over.

Cheaper or different alternatives

If the event bill or the Amplitude ownership is a concern, these tools are the usual comparisons. Prices are from each vendor's own page as of November 2026.

• GrowthBook: the free Starter plan covers up to 3 users and 1 project with unlimited flags, experiments and traffic; Pro is $40 per seat a month for up to 30 users; Enterprise is custom. It runs on its cloud or self-hosted, and can read results from your own data warehouse. See GrowthBook pricing.
• PostHog: free every month for 1 million feature flag requests, with experiments billed together with flags, unlimited team members and 1 project. Above that it is pay as you go per product, with no minimum spend, and you can set billing limits. See PostHog pricing.
• LaunchDarkly: the Developer plan is $0 with 5 service connections and 1,000 client-side monthly active users. Foundation is pay as you go past those amounts, at $10 per extra service connection and $8.33 per extra 1,000 client-side MAU billed yearly ($12 and $10 billed monthly). Enterprise is custom. See LaunchDarkly pricing.
• Flagsmith: Free covers 50,000 requests a month and 1 team member; Start-Up is $40 a month billed yearly ($45 monthly) for 1 million requests and 3 team members; Scale-Up is $250 a month billed yearly. Extra API calls start at $50 per million. See Flagsmith pricing.

The main difference is the billing unit. Statsig bills metered events, GrowthBook bills seats, PostHog and Flagsmith bill flag requests, and LaunchDarkly bills service connections and client-side MAU. Estimate your own volume in each unit before you compare headline prices.

FAQs

Is Statsig free?

Yes. The Developer plan is free with no credit card and includes 2 million metered events a month, unlimited flag and config checks, 50,000 session replays and unlimited seats. Above 2 million events you either upgrade to Pro or lose Metric Lift calculations for the rest of the month.

How much does Statsig cost per month?

Pro costs $150 a month with 5 million events included and $0.05 per 1,000 events after that. Enterprise is priced by contract through sales.

Does Statsig charge per user or per seat?

No. The free plan lists unlimited seats, Pro includes everything in the free plan, and billing is based on metered events such as exposures and logged events, not on team members or monthly users.

What counts as an event in Statsig pricing?

Exposures (checks of experiments, and of flags with Metric Lifts on), log events sent through the SDK or imported, ingested metrics from a warehouse and custom metrics. Flag checks without Metric Lifts, disabled flags and inactive experiments are not metered.

Is Statsig owned by OpenAI or Amplitude?

Amplitude. Statsig agreed to join OpenAI in September 2025, and its blog says Amplitude acquired it on May 5, 2026. The original team stayed at OpenAI; the product, brand and customers are now part of Amplitude.

How many projects does Statsig Pro include?

One. Each Pro subscription applies to a single project, and other projects must be upgraded separately. Enterprise accounts can share one contract across multiple projects.
