# How Croct compares

Croct is a component-based headless CMS with a built-in CDP, server-side personalization,
Bayesian A/B testing and real-time analytics. Most tools it gets compared to do one of those
things. The pages below go capability by capability against each of them.

## How they compare

Platforms Croct replaces, because it does the same job with server-side rendering, built-in
segmentation and no separate CDP:

|:-------------------------------------------|:--------------------------------------------------------|
| [Optimizely](/comparison/optimizely)       | Server-side rendering, a free plan, no CDP to buy       |
| [VWO](/comparison/vwo)                     | No flicker, no anti-flicker snippet, a CMS of its own   |
| [Dynamic Yield](/comparison/dynamic-yield) | Fits any business, installs in hours, starts free       |
| [Mutiny](/comparison/mutiny)               | Personalization past the landing page, a CMS of its own |
| [Prepr](/comparison/prepr)                 | Bayesian tests on unsampled data, server-side delivery  |
| [Builder.io](/comparison/builder)          | Components stay in your codebase, native experiments    |
| [Contentful](/comparison/contentful)       | Component-based content, native testing and analytics   |
| [Segment](/comparison/segment)             | Acts on the data instead of only routing it             |

Content platforms Croct works alongside, adding the decision layer they do not carry:

## Why teams choose Croct

- **Server-side by design.** Content is resolved before the page is sent, so experiences
  arrive personalized with no flicker and no anti-flicker snippet blanking the page.
- **One platform, no extra vendors.** Segmentation, user profiles, experimentation and
  analytics are built in, so there is no separate CDP, feature-flag tool or analytics
  contract to buy and wire together.
- **Built for headless stacks.** Croct sits alongside Storyblok, Sanity, Strapi, Contentful
  or Shopify Hydrogen and makes the content they hold contextual, instead of replacing them.
- **Marketers ship without developers.** After setup, audiences, experiences, A/B tests,
  scheduling and preview all happen in the Croct interface.
- **Bayesian experimentation on unsampled data.** A/B, A/B/n and multivariate tests with
  cross-device consistency for identified users and bot traffic filtered out.

## Adopting Croct

Croct runs alongside what you already have, so adoption is incremental rather than a
migration.

Setup is one command, `npx croct@latest init`, which installs the SDK, wires the provider
and generates TypeScript types for every slot. Official SDKs cover Next.js, React, Vue,
Nuxt, JavaScript, PHP, Laravel, Symfony, Drupal, and Shopify Hydrogen. Most teams are live
the same day, and the forever-free plan needs no credit card or commitment.

## Frequently asked questions

### Does Croct replace my CMS?

Not necessarily. Against a headless CMS it adds the decision layer. Against a
personalization or experimentation platform it usually replaces the tool outright.

### Do I need a CDP as well?

No. Segmentation, real-time profiles and data unification are built in, and profiles export
to your warehouse or to any tool you already run.

### What statistics does the A/B testing use?

Bayesian, computed on unsampled data, with A/B, A/B/n and multivariate tests, cross-device
consistency for identified users, and bot traffic filtered out.

### What does it cost?

The forever-free plan covers 10,000 monthly active users with 3 content slots and 1
experience or experiment, and needs no credit card. Growth starts at $100 per month billed
annually for 20,000 monthly active users. Scale is custom.
