Statsig Alternative 2026: Why Teams Switch to Rollgate

This was originally published on rollgate.io/blog/statsig-alternative.

Why Teams Are Looking for a Statsig Alternative

Statsig is a strong product. It bundles feature flags, A/B testing, product analytics, and session replays into one platform — competing with Amplitude and Mixpanel as much as it competes with LaunchDarkly. If you need all of those things, Statsig's pitch is compelling.

But most teams searching for a "Statsig alternative" hit one of three friction points:

1. Pricing scales on product analytics events, not on feature flag usage. Even if you use Statsig only for flags, you pay for the analytics platform you don't need.
2. EU data residency is Enterprise-only. GDPR-sensitive teams hit a paywall before they can compare seriously.
3. The Pro tier is capped at 1 project. Agencies, consultancies, and teams with separate staging/prod orgs hit this limit fast.

If feature flags are your primary use case — and you already have PostHog or Amplitude or Mixpanel covering product analytics — there's a cheaper, simpler, EU-friendly path. That's where Rollgate fits in.

What to Look for in a Statsig Alternative

If you're evaluating alternatives to Statsig, here's what actually matters:

Pricing That Tracks Flag Usage, Not Event Volume

Statsig prices on events. If you instrument your app with click tracking, page views, and funnel events (the whole point of the analytics platform), your bill scales with product usage. For pure feature flag use cases, this overcharges you for capacity you don't need.

The better model: flat pricing on SDK requests, where you know exactly what you'll pay each month. See our feature flags pricing comparison for a deeper breakdown of pricing models across vendors.

EU Data Residency Without Upgrading to Enterprise

If you serve European users, EU-hosted flag data significantly simplifies GDPR compliance (Chapter V on international transfers). US-only infrastructure remains legal under SCCs and the EU-US Data Privacy Framework, but it adds vendor risk assessment work that EU-based DPOs would rather avoid. Statsig offers EU hosting only on Enterprise contracts ("contact sales"). For a 5-person team that just needs GDPR compliance, that's a non-starter — they end up using Statsig's US infrastructure with a DPA, which works legally but adds friction.

The cleaner alternative: a vendor that hosts in the EU by default, on every plan, with no contract negotiation.

Multi-Project Support on Paid Tiers

If you run an agency, consult on multiple client products, or separate staging and production into distinct projects (a common pattern), Statsig's Pro tier becomes a blocker: it allows only 1 project. You either pay Enterprise pricing or you cram everything into one workspace.

A reasonable Pro plan should give you 5-10 projects without forcing the Enterprise conversation.

A Feature Flag Tool, Not a Product Analytics Platform That Also Does Flags

Statsig is a product analytics platform that includes feature flags. The dashboard is built around experimentation and analytics workflows. If you just want to ship a flag, gate a feature, and roll back when something breaks, the cognitive overhead of navigating an analytics-first UI is friction you didn't sign up for.

Statsig Pricing Breakdown: Where the Cost Actually Comes From

Statsig's pricing looks generous at a glance. Here's the actual structure:

A few things to call out:

1. Pro Tier 1-project limit. If you have a staging org separate from production, or you're an agency managing 3 client products, you immediately need Enterprise.
2. Event overage is $0.05 per 1K events. If you instrument product analytics seriously (click events, page views, conversion funnels), you'll burn through 5M events fast. A B2C product with 50K MAU and 100 events/user/month = 5M events. Worth noting: in Statsig, every flag check ("gate check") generates an exposure event that counts toward this quota — so even a flag-only use case isn't immune from event scaling, you're just buying bundled analytics capacity you may not use.
3. EU data residency = Enterprise only. No published price, "contact sales" required.
4. Session replays count as a separate quota. 100K replays/month is generous but not unlimited; high-traffic apps eat through it.

The bigger structural issue: Statsig prices the bundle, not the individual product. If feature flags are 10% of why you're there but 90% of your need, you're paying for 90% of capacity you don't use.

Feature Flag Tools Compared: Rollgate vs Statsig vs the Alternatives

Here's how the major feature flag platforms compare in 2026:

Note on pricing: All figures based on each vendor's public pricing as of May 2026. Enterprise contracts vary significantly. Verify directly with each vendor before purchase.

The clearest difference: Statsig's workflow is optimized for high-velocity experimentation — flags are the source of analytics events, and the UI is built around designing tests, viewing exposures, and analyzing variants. Rollgate's workflow is optimized for flag operations — toggle, target, schedule, rollback. Both are valid for their core use case, but if you just need a configuration toggle, Statsig's analytics-shaped UI is friction; if you need experimentation-grade analysis, Rollgate's basic A/B testing won't replace it.

Real Cost Comparison: Pure Feature Flag Use Case

Let's compare costs for a team that wants feature flags + light A/B testing, but already runs product analytics on PostHog or Mixpanel.

The pattern: if you don't need product analytics, you're overpaying with Statsig. If you do need product analytics, the comparison shifts — Statsig's bundle might be worth it. But most teams already have PostHog (free up to 1M events/month) or Mixpanel set up, and adding Statsig means paying twice for analytics capability they already have.

Why Rollgate Is a Cleaner Statsig Alternative for Feature-Flag-First Teams

Pricing That Matches Your Use Case

Rollgate prices on SDK requests, not on product analytics events. Your monthly bill correlates with how many times your apps check feature flags — a metric directly tied to your usage of the product.

A team polling every 30 seconds generates about 86K SDK requests per month per client instance. With SSE streaming and caching (both default in Rollgate SDKs), real-world volume is significantly lower.

EU Data Residency on Every Plan

Rollgate hosts in Germany (Hetzner Falkenstein). Every plan — including the free tier — uses the same EU infrastructure. No upgrade required, no DPA negotiation, no separate EU contract. Just GDPR-compliant by default.

For teams shipping to European users, this means you can evaluate the product on the free tier and migrate to production without any data residency rework.

Multi-Project on Pro Without Enterprise Pricing

Rollgate's Pro tier includes 10 projects. Run staging and production as separate projects, manage multiple client products as an agency, or split flags by team — without hitting the "you need Enterprise" wall at 2 projects.

13 SDKs Built for Feature Flag Use Cases

Every Rollgate SDK ships with circuit breakers, retry with exponential backoff, local caching, and graceful degradation. The API surface is intentionally minimal: isEnabled(), getString(), getNumber(), and getJson(). No analytics SDK to integrate, no event taxonomy to design, no replay configuration to maintain.

Example, Node.js:

import { RollgateClient } from '@rollgate/sdk-node';

const client = new RollgateClient({
  apiKey: process.env.ROLLGATE_SERVER_KEY,
  enableSSE: true,
});

await client.initialize();

if (client.isEnabled('new-checkout', { id: userId })) {
  return newCheckoutFlow();
}
return legacyCheckoutFlow();

Server-side flag evaluation with sub-millisecond latency, real-time updates over SSE, automatic fallback to cache if the API is unreachable. Same surface across 13 languages — see the Node.js, Go, Python, and .NET guides for stack-specific examples.

What Statsig Does Better

Honest acknowledgment: Statsig is the better choice for certain teams.

Integrated Product Analytics + Experimentation

If you don't have a product analytics tool yet and you're choosing between adding Amplitude/Mixpanel/PostHog and a feature flag tool, Statsig's bundle is genuinely cheaper than buying two products. The Developer tier (free, 2M events) covers a lot of side projects and early-stage products.

Session Replays

Statsig includes session replays. Combined with feature flag context (you can replay only sessions where a specific flag was enabled), this is powerful for debugging and qualitative research. Rollgate doesn't offer replays — you'd integrate something like PostHog's replay product separately.

Statistical Experimentation Maturity

Statsig's experimentation engine includes Bayesian and frequentist analysis, sequential testing, CUPED variance reduction, and metric guardrails. If you're running high-stakes A/B tests where statistical rigor matters, Statsig's tooling is more mature than Rollgate's A/B testing (which covers the basics — variant assignment, conversion tracking, confidence intervals).

30+ SDK Coverage

Statsig has more language SDKs than Rollgate's 13. If you need a Rust, Erlang, or Lua SDK, Statsig has it. Rollgate covers the top 12-13 platforms that handle 95% of teams — but if your stack includes a niche language, verify SDK availability first.

Warehouse-Native + Sidecar Deployment Options

Statsig Enterprise supports warehouse-native deployment (run computation on your own data warehouse like Snowflake or BigQuery), plus the Statsig Sidecar/Forwarder for local proxy caching. This is valuable for teams with strict data governance, ultra-low-latency requirements, or massive event volumes. Rollgate doesn't yet offer either — the self-hosted edition is on the roadmap but not shipped.

Multi-Armed Bandit Autotune

Statsig includes an Autotune feature that uses multi-armed bandit algorithms to automatically route more traffic toward winning variants during an experiment, accelerating convergence. Most flag-only tools (Rollgate included) don't ship this out of the box. If you're running revenue-impacting experiments where wait-time-to-conclusion costs money, Statsig's Autotune is a real edge.

Migration from Statsig to Rollgate

Switching from Statsig is straightforward for feature flags. The migration is more complex if you're also moving analytics — that part requires picking a separate analytics vendor (we recommend PostHog for the closest feature parity at a lower cost).

Step 1: Audit Your Statsig Flags

Export your active feature flags from Statsig. For each one, note:

• Flag name and type (boolean, string, JSON)
• Targeting rules (user attributes, segments)
• Rollout percentage and conditions
• Default values
• Which environments use it

Most teams find that 30-50% of flags are stale (completed rollouts, abandoned experiments, dead kill switches). Migration is a good time to clean up.

Step 2: Recreate Flags in Rollgate

Create equivalent flags in the Rollgate dashboard. Rollgate supports the same flag types: boolean, string, number, and JSON. Targeting rules translate directly — user attributes, segments, and percentage rollouts all work the same way.

Step 3: Swap the SDK

Here's how Statsig SDKs map to Rollgate equivalents:

Step 4: Update Flag Evaluation Calls

The APIs are similar enough that migration is largely find-and-replace.

Statsig (Node.js):

import { Statsig } from 'statsig-node';

await Statsig.initialize(process.env.STATSIG_SERVER_KEY);

const user = { userID: '123', email: 'alice@example.com' };
if (Statsig.checkGate(user, 'new_checkout')) {
  return newCheckoutFlow();
}

Rollgate (Node.js):

import { RollgateClient } from '@rollgate/sdk-node';

const client = new RollgateClient({
  apiKey: process.env.ROLLGATE_SERVER_KEY,
});
await client.initialize();

if (client.isEnabled('new-checkout', { id: '123', attributes: { email: 'alice@example.com' } })) {
  return newCheckoutFlow();
}

Step 5: Decide on Analytics

This is the part that requires a separate decision. If you were using Statsig's analytics features (events, funnels, experimentation), you have a few options:

• PostHog: Open-source, generous free tier (1M events/month), product analytics + session replays + feature flags (yes, you could use PostHog for flags too — see our notes on PostHog as an alternative).
• Mixpanel: Mature product analytics, simpler than Amplitude. Free tier up to 20M events/month.
• Amplitude: Strong for behavioral analytics. Free tier up to 10M events.
• Self-hosted: Plausible for privacy-focused page tracking, Umami for similar.

For experimentation, GrowthBook is the strongest open-source option if you need Bayesian analysis without Statsig's pricing.

Step 6: Clean Up

Remove Statsig SDK packages, delete STATSIG_* environment variables, cancel your subscription. Most teams complete the flag migration in 1-3 days for small projects, 1 week for larger codebases.

When to Choose Each Tool

Choose Rollgate if:

• Feature flags are your primary need — analytics is already handled elsewhere
• You need EU data residency without an Enterprise contract
• You want multi-project support on a Pro tier (10 projects vs Statsig's 1)
• You prefer flat, predictable pricing on SDK requests vs event-based scaling

Choose ConfigCat if:

• You have very simple needs (boolean toggles, basic targeting, no scheduling)
• You want a no-frills tool that does the basics at a reasonable price

FAQ

Is there a cheaper alternative to Statsig for feature flags?

Yes. Rollgate's Starter plan is €39/month vs Statsig's $150/month Pro, with 5 projects vs Statsig's 1, and EU data residency included. If you don't need bundled product analytics, Rollgate covers feature flag use cases for roughly a quarter of the cost.

If you want a free option, both Statsig's Developer tier and Rollgate's Free tier are generous — Rollgate gives 500K SDK requests/month with no event quota, Statsig gives 2M events/month with unlimited flags.

Does Statsig have an EU data residency option?

Statsig offers EU hosting only on Enterprise contracts. There is no published price — you must contact sales. For teams that need GDPR compliance without sales negotiation, Rollgate hosts in Germany on every plan (including the free tier) by default.

Why does Statsig Pro only allow 1 project?

It's a tier-segmentation decision by Statsig — multi-project support is reserved for Enterprise. The practical impact: if you separate staging from production (a common pattern), or you're an agency with multiple clients, you must either upgrade to Enterprise or compress everything into one workspace with naming conventions. Rollgate's Pro tier includes 10 projects without the Enterprise conversation.

Can I migrate from Statsig without downtime?

Yes. Run both SDKs in parallel during the transition: evaluate flags from both Statsig and Rollgate, log any discrepancies, then remove the Statsig SDK once you've verified values match. For non-critical flags, you can migrate directly — the API surface is similar enough that the change is largely find-and-replace.

Is Statsig's free tier actually free, or does it convert to paid automatically?

Statsig's Developer tier is persistent free (not a trial) — no credit card required, no auto-conversion to paid. You stay on Developer until you explicitly upgrade or exceed the event limit. Same model as Rollgate's free tier.

What's the best feature-flag-only alternative to Statsig?

For a managed cloud feature flag service without bundled analytics, Rollgate is the closest match on price ($39/mo vs $150/mo), with EU hosting and multi-project support included on Pro. For a self-hosted option, Unleash (MIT license) is the strongest open-source choice.

If you need feature flags plus analytics in one platform but want a cheaper bundle than Statsig, PostHog offers feature flags as part of its product analytics platform (free up to 1M events/month).

Does Rollgate support A/B testing like Statsig?

Yes, on Pro plans and above. Rollgate's A/B testing covers variant assignment, conversion tracking, and basic statistical analysis (confidence intervals, sample size calculation). If you need advanced experimentation methods (Bayesian, CUPED variance reduction, sequential testing), Statsig is more mature here. See our A/B testing with feature flags guide for the Rollgate approach.

Can I use Rollgate alongside my existing analytics tool?

Yes — that's the recommended pattern. Rollgate emits flag evaluation events that you forward to PostHog, Mixpanel, Amplitude, or any other analytics tool. This keeps feature flag logic separate from product analytics, which is easier to reason about than Statsig's bundled approach.

How long does migration from Statsig take?

For most teams, 1-3 days for a small project with a handful of flags, 1 week for larger codebases with multiple services. The longest part is usually auditing stale flags (which you should do anyway) and deciding on a replacement for Statsig's analytics features if you were using them.

Get Started for Free

Rollgate's free tier includes 500K SDK requests/month, 3 projects, all 13 SDKs, and unlimited flags. EU-hosted in Germany. No credit card required.
