Statsig
Statsig bundles feature flags, A/B testing, and product analytics on one data model — plus session replay and a warehouse-native option.
Statsig earns a look when your flags, A/B tests, and product analytics live in three tools with three data models — and unlike most consolidation pitches, the stats engine holds up: CUPED, sequential testing, holdouts, switchbacks, and multi-arm bandits are all published on the plan comparison, not parked on a roadmap. The Developer tier at $0/mo with 2M events, 50,000 session replays, and unlimited seats is a genuinely low-risk trial. The catch is the cliff between Pro at $150/mo and Enterprise: warehouse-native deployment, SSO, RBAC, and HIPAA eligibility all sit in the custom-priced tier. If SSO or warehouse-native is a day-one requirement, price Enterprise before you instrument anything.

Skip Statsig if you need SSO, role-based access control, or warehouse-native deployment on a self-serve budget — those sit on Enterprise contracts, so a cheaper flag-only tool that bundles SSO will beat it for a security-first team under 10 engineers.
Pro includes 5M events; past that you pay $0.05 per 1K events, which adds roughly $50 for every extra million you send.
The $0 Developer tier with 2M events, 50,000 replays, and unlimited seats undercuts nearly every flag-plus-analytics competitor's free plan, and Pro at $150/mo for 5M events lands well below what a full LaunchDarkly or Optimizely seat-based contract costs at the same team size. The comparison flips at Enterprise, where warehouse-native and SSO buyers pay custom pricing against Eppo or a warehouse-native specialist.

What is Statsig?
Statsig — Statsig bundles feature flags, A/B testing, and product analytics on one data model — plus session replay and a warehouse-native option. Best for Engineering teams consolidating flags, A/B testing, and analytics onto one platform, Data scientists who need CUPED, sequential testing, and warehouse-native experimentation, Product managers running hundreds of tests a year who self-serve their own results. Free to start; paid plans from $150/mo.
Statsig is a product development platform that puts feature flags, experimentation, product analytics, session replay, web analytics, and infra analytics on a single data model. Engineering and data teams use it to roll features out gradually, run A/B/n tests, and read results in the same tool that served the variant — a session replay links back to the flag or experiment that shaped it, and flag impact analysis turns each release into a measurable test. The stats engine is the reason people switch: Bayesian and frequentist analysis, CUPED, Bonferroni and Benjamini-Hochberg corrections, winsorization, sequential testing, switchback tests, non-inferiority tests, holdouts, layers, and multi-arm bandits are all listed as shipping capabilities on the pricing comparison page. Warehouse Native runs experimentation and analytics inside your own Snowflake, BigQuery, Redshift, or Athena environment with no ETL, which is the lever for governance-heavy orgs. AI experimentation (prompts, graders, offline and online evals) is documented as Early Access in the docs, and the July 2026 MCP work takes a feature gate through its full lifecycle headlessly. SDKs span roughly 30 client and server languages from React and Next.js to Go, Rust, and C++. Statsig reports 1+ trillion events a day, 2.5 billion monthly experiment subjects, and 99.99% API and console uptime. The free Developer tier includes 2M events a month with unlimited seats — enough to benchmark it against LaunchDarkly, Optimizely, Split, or Eppo before committing budget. Statsig is part of the Amplitude family.
Key features
- A/B/n testing with Bayesian and frequentist analysis
- CUPED for shorter experiment runtime using pre-period data
- Bonferroni and Benjamini-Hochberg multiple-comparison corrections
- Winsorization to reduce outlier influence on results
- Sequential testing to prevent early-peeking on A/B results
- Switchback tests for cases where standard randomization isn't feasible
- Non-inferiority tests to show a treatment isn't worse than control
- Holdouts to measure cumulative feature impact
- Layers and multi-arm bandit experiments
- Feature flags with percentage-based and automated scheduled rollouts
- Attribute-based, segment-based, and environment-based targeting
- Dynamic configs for hosted JSON values
- Parameter stores for web and mobile localization strings
- Flag impact analysis, monitoring metrics, and automated alerts
- Session replay linked to flags, experiments, and metrics
Behind the verdict
The pitch for Statsig is consolidation, and the specific reason it works is that the experimentation layer is not an afterthought bolted onto a flag service. The pricing comparison page lists CUPED, Bonferroni correction, winsorization, Benjamini-Hochberg, stratified sampling, automated heterogeneous effect detection, interaction effect detection, sequential testing, switchback tests, and non-inferiority tests as distinct capabilities. That is a data scientist's checklist, not a marketing list, and it matters most when your traffic is thin or your test velocity is high — CUPED shortens runtime using pre-period data, and the multiple-comparison corrections stop a dashboard full of simultaneous tests from producing false winners. The operational side is equally concrete. Feature flags ship with percentage-based rollouts, automated scheduled rollouts with pre-defined stages, attribute-based and segment-based targeting, dynamic configs for hosted JSON, parameter stores for mobile and web localization strings, monitoring metrics, flag impact analysis, and automated alerts. Because flags, experiments, and analytics share one event pipeline, a session replay can be filtered down to the variant a user saw — qualitative and quantitative evidence in the same place rather than a CSV export between them. The honest weaknesses. First, breadth is a learning curve: experimentation, flags, analytics, replay, web analytics, infra analytics, and Early Access AI evals is a lot of surface for a team that just wants on/off switches, and you need someone who will own SDK installation and event instrumentation or nothing works. Second, the Pro-to-Enterprise cliff is real. Pro at $150/mo includes 5M events and charges $0.05 per 1K beyond that, but warehouse-native deployment, outgoing data integrations, data warehouse imports, SSO, role-based access control, teams, priority support, and HIPAA eligibility (BAA required) are all Enterprise-only at custom pricing. A security review that requires SSO will push you off Pro regardless of event volume. Third, the AI experimentation features — Prompts & Graders, Offline Evals, Online Evals, and the Control Panel — are labeled Early Access in Statsig's own docs, so treat them as a bonus, not the deciding factor. Fourth, Warehouse Native changes your architecture: it removes ETL and keeps data in your Snowflake, BigQuery, Redshift, or Athena account, but it also means your warehouse's cost, permissions, and query performance become part of the experimentation loop. The MCP work from July 2026 and the August 2026 release recap point in a useful direction — driving a feature gate through its lifecycle without a browser is exactly what CI pipelines and coding agents want. But we have not verified the release cadence, so judge current velocity from the product updates page yourself rather than from any claim here. Where it fits: mid-market and enterprise product orgs with a data team, a real experiment backlog, and a mandate to
Limitations
- The free Developer tier includes 2M events per month, 50,000 session replays per month, and 1-year analytics retention, with unlimited seats and unlimited flag and config checks.
- Pro at $150/mo includes 5M events, then charges $0.05 per 1K events, and caps session replays at 100,000 per month.
- Warehouse-native deployment, outgoing data integrations, data warehouse imports, SSO, role-based access controls and teams, priority support, and HIPAA eligibility (BAA required) are all reserved for Enterprise contracts at custom pricing — a real cliff from Pro.
- The platform spans experimentation, flags, product analytics, session replay, web analytics, infra analytics, and AI experimentation, which is a learning curve for teams with simple needs.
- AI experimentation features (Prompts & Graders, Offline Evals, Online Evals, Control Panel) are documented as Early Access in Statsig's own docs, so validate them against your use case before making them the deciding factor.

- −Per-seat billing is rough for orgs that need many non-engineering seats
- −Documentation gaps and at least one critical technical issue reported by active users
- −Public pricing is not displayed, forcing every buyer into a sales conversation
- • Per-seat billing adds up when analysts and PMs need access alongside engineers
- • Warehouse-native mode consumes your own Snowflake/BigQuery compute, so the real cost shows up on the warehouse bill

Where the pricing makes sense
The company stage and team size where Statsig's pricing actually pencils out — and where peers do it cheaper.
The $0 Developer tier with 2M events, 50,000 replays, and unlimited seats undercuts nearly every flag-plus-analytics competitor's free plan, and Pro at $150/mo for 5M events lands well below what a full LaunchDarkly or Optimizely seat-based contract costs at the same team size. The comparison flips at Enterprise, where warehouse-native and SSO buyers pay custom pricing against Eppo or a warehouse-native specialist.
Has Statsig's pricing changed?
No plan price for Statsig has moved since we began logging in Aug 2026; the pricing page is re-read on every verification pass.
Who should pick Statsig?
Pick Statsig if you are Engineering teams consolidating flags, A/B testing, and analytics onto one platform, Data scientists who need CUPED, sequential testing, and warehouse-native experimentation, Product managers running hundreds of tests a year who self-serve their own results, Governance-heavy orgs that must keep experiment data inside their own warehouse.
Look elsewhere if you are Small teams that only need basic on/off feature flags, Teams with no one to own SDK installation and event instrumentation, Very low-traffic apps that will never approach the 2M monthly event cap, Security-conscious buyers who need SSO but won't buy an Enterprise contract.
Skip it if Skip Statsig if you need SSO, role-based access control, or warehouse-native deployment on a self-serve budget — those sit on Enterprise contracts, so a cheaper flag-only tool that bundles SSO will beat it for a security-first team under 10 engineers.
GeneratedReal-world workflow fit
Concrete scenarios for the personas Statsig actually fits — and what changes day-one when you adopt it.
You have a checkout redesign queued but traffic only supports a four-week test. You install the Node.js or Python SDK, log the exposure event, and turn on CUPED to pull in pre-period data and shorten the required runtime, then apply Benjamini-Hochberg because three other tests are running concurrently.
Outcome: A decision in weeks rather than a month and a half, with the false-discovery risk from overlapping tests explicitly controlled instead of ignored.
You want to ship a new onboarding flow to 5% of new signups, then ramp. You set an automated scheduled rollout with pre-defined stages, attach monitoring metrics and an alert to the funnel step you're worried about, and later open session replays filtered to the variant.
Outcome: A staged release with automatic regression alerts and qualitative replay evidence in one place, without filing a ticket for each step.
Your security team won't let experiment exposure data leave the warehouse. You choose Warehouse Native, point Statsig at your Snowflake account, and run the flag checks against evaluated configs while assignments and metrics stay in your own tables.
Outcome: Experimentation without a new data-egress approval, though you'll need to budget warehouse compute for the added queries.
Use cases
- Run A/B tests with CUPED and multiple-comparison corrections to reach a decision on a shorter sample.
- Gradually roll out a feature with percentage-based stages and monitoring metrics that catch regressions.
- Filter session replays to the experiment variant or flag a user actually saw.
- Keep experiment assignment and metric data inside your own Snowflake, BigQuery, Redshift, or Athena environment.
- Watch product and infra health together using OpenTelemetry traces alongside product metrics.
- Drive a feature gate through its full lifecycle from CI or an agent via the MCP server.
- Run holdouts to measure the cumulative impact of a set of shipped features.
- Let a multi-arm bandit algorithm pick the winning treatment across several variants.
Setup time & first value
How long it actually takes to get something useful out of Statsig — broken out by persona, not the marketing-page minute.
A single-service SDK install (React, Node.js, Python) is a matter of minutes to first flag check — Statsig's docs put the quickstart at 'minutes'. Realistic first-value: half a day to a working flag on the Developer tier, one to three weeks to instrumented metrics and a first valid experiment, and four to eight weeks for a Warehouse Native rollout once warehouse permissions and schemas are agreed
Switching to or from Statsig
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From LaunchDarkly: map flag keys to Statsig gates, port targeting rules and segments, then run both SDKs in parallel until flag values match.
- →From Optimizely: recreate experiments as Statsig experiments, move audience definitions into segments, and re-instrument exposure events on the Statsig SDK.
- →From Eppo: export warehouse assignment tables and use Statsig's warehouse imports on Enterprise to analyze existing experiment data.
- →From Split: translate treatments into gates with percentage rollouts, then re-run live experiments under Statsig's stats engine rather than trusting translated results.
- ↗To LaunchDarkly: export gate definitions and targeting rules, then re-implement flag evaluation in LD's SDKs — experimentation and analytics history does not transfer.
- ↗To Eppo: keep experiment assignments in your warehouse and re-point Eppo at the same tables, accepting that Statsig's session replay and product analytics stay behind.
- ↗To Amplitude alone: since Statsig is part of the Amplitude family, teams that only need analytics can consolidate there and drop the flag layer.
