# GrowthBook Alternatives for Next.js A/B Testing

> GrowthBook is a strong open-source pick, but self-hosting and middleware ownership aren't for everyone. Here are the real alternatives for a Next.js landing page test.

The main GrowthBook alternatives for Next.js A/B testing are Statsig (hosted, fastest setup, no self-hosting), PostHog (bundles experiments with full product analytics), Vercel Edge Config (lowest latency if you're already on Vercel), and Landtest (no SDK or middleware ownership, split runs through your deploy pipeline instead). GrowthBook itself is a good default — open source, free to self-host, warehouse-native — so these alternatives matter specifically when one of its tradeoffs doesn't fit: you don't want to run the infrastructure, you don't want experiment logic living in `middleware.ts`, or you want more than flag-based experimentation out of the box.

This is Landtest's own comparison content. Last updated 2026-09-30.

## When GrowthBook is the right call

If you want to own your data, you're fine self-hosting (Docker Compose, no artificial seat/event limits, MIT license), and your experiments already read from a data warehouse — GrowthBook's core differentiator is being warehouse-native rather than owning its own ingest pipeline. For a team with the infrastructure appetite, this is hard to beat on cost and control. [GrowthBook's own site](https://www.growthbook.io) documents the self-hosted setup directly.

## Statsig — when you want zero infrastructure

Statsig is the pick if you want a hosted platform today with minimal setup: 2M events/month free, then usage-based. No self-hosting option, so you're trusting a third party with experiment data by default. For teams already running Statsig for product feature flags, extending it to a landing page test is often the path of least resistance, even if it's more platform than a single page test strictly needs.

## PostHog — when experiments are one part of a bigger analytics need

PostHog's pitch is one tool for flags, experiments, session replay, and funnels. If you're going to want product analytics anyway, adopting PostHog for the A/B test means you're not paying for and integrating a second tool later. [PostHog's own comparison against GrowthBook](https://posthog.com/blog/posthog-vs-growthbook) is a fair primary source on the tradeoffs. The downside for a landing-page-only use case: you're bringing in a full analytics platform, client-side SDK included, to answer one experiment question.

## Vercel Edge Config — when you're Vercel-only and want zero flicker

If your whole stack is on Vercel, Edge Config plus Edge Middleware gives you assignment at the edge before the response renders, which is the cleanest way to avoid a flash of the control variant. [Vercel's zero-CLS experiment guide](https://vercel.com/blog/zero-cls-experiments-nextjs-edge-config) documents the pattern with sub-15ms P99 reads. The tradeoff is that the split logic lives in your `middleware.ts`, same composition concern as any other middleware-based tool — see [how to A/B test without middleware conflicts](/blog/ab-test-nextjs-landing-page-without-middleware-conflicts) if that's already crowded with auth logic.

## Landtest — when you don't want to own the split logic at all

Landtest differs from every option above in where the split lives: not in a client SDK, not in middleware, not in a warehouse query — it runs through your repo's own deploy pipeline. You connect GitHub, the AI generates the variant as a branch with its own preview deploy, and traffic is split at the hosting layer using your existing CI/CD. There's no runtime for Landtest on the visitor's request at all. Stats are computed with mSPRT and SRM checks rather than a naive significance test, so you can check results early without inflating false positives. When you call a winner, the losing branch and any test scaffolding are removed in one PR.

The honest read: this is a narrower tool than GrowthBook. It's built for one thing — landing page experiments that start and end as a GitHub PR — not company-wide feature flagging. If you need flags for backend rollouts too, GrowthBook or a flagging-first tool still makes more sense as your single system.

## Comparison at a glance

| | GrowthBook | Statsig | PostHog | Vercel Edge Config | Landtest |
|---|---|---|---|---|---|
| Self-hosted | Yes, free | No | Unsupported | N/A (Vercel-hosted) | N/A (your host) |
| Where the split runs | Your middleware/server | Client/server SDK | Client/server SDK | Edge middleware | Your deploy pipeline |
| Flicker risk | Depends on integration | Client-side by default | Client-side by default | None (edge) | None (build-time split) |
| Best for | Warehouse-native experimentation | Fast hosted setup | Flags + full analytics | Vercel-only, zero-flicker | No runtime, PR-based cleanup |

## FAQ

**Is GrowthBook free?**
Self-hosted GrowthBook is free under the MIT license with no artificial limits; GrowthBook Cloud has a free tier for up to three users and paid tiers beyond that.

**What's the closest alternative to GrowthBook if I don't want to self-host?**
Statsig or PostHog, both hosted SaaS with generous free tiers. Neither offers self-hosting as a supported path.

**Does Landtest replace GrowthBook for feature flags?**
No — Landtest is scoped to landing page A/B tests that live and die with a GitHub PR, not general-purpose feature flagging. If you need flags across your backend too, GrowthBook remains the better single system.
