# Croct

Croct is a component-based headless CMS with personalization and A/B testing built in. It
resolves content on the server, so pages arrive already personalized, with no flicker and
no anti-flicker snippet. It works alongside a CMS you already run, such as Storyblok,
Sanity or Strapi, and it needs no separate customer data platform.

## Who it is for

Marketing and growth teams who want to run experiments and personalize pages without filing a
ticket for every change, and developers who want that to happen without a render-blocking script
or a second data vendor.

Marketers get audiences, experiences, A/B tests, scheduling and preview in the Croct interface
after the first setup. Developers get typed SDKs, versioned component schemas and fallback
content that keeps the page up when anything goes wrong.

## Why teams pick 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.

## Capabilities

- **A/B testing.** Bayesian statistics on unsampled data. A/B, A/B/n and multivariate
  tests, cross-device consistency for identified users, and bot filtering.
- **Personalization.** Server-side content decisions per visitor, so there is no flash of
  default content and no flicker.
- **User profiles.** Real-time profiles built from behavior, enriched from your own data
  and exportable anywhere.
- **Segmentation.** Audiences that update the moment a visitor qualifies, written in CQL,
  an English-like query language, for example `user is returning and location's city's name is
  "New York"`.
- **Content management.** Components and slots that make content contextual rather than
  static, versioned and typed end to end.

## How it works

Content lives in slots, the placeholders you put in your application. Each slot renders a
component, and Croct decides which variation each visitor sees at request time, on the server.
End-to-end response times run under 90 milliseconds at the 95th percentile.

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, Astro, Remix, Svelte, Gatsby, JavaScript, PHP, Laravel and Shopify Hydrogen. Most
teams are live the same day, and the forever-free plan needs no credit card.

## Pricing

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. See [pricing](/pricing) for the
full table.

## Integrations

Croct enriches profiles from and exports data to the tools you already run.

**Headless commerce and CMS.** [Storyblok](/integrations/storyblok),
[Strapi](/integrations/strapi), [Sanity](/integrations/sanity),
[Shopify](/integrations/shopify), [Magento](/integrations/magento),
[Salesforce Commerce](/integrations/salesforce-commerce) and [VTEX](/integrations/vtex).
Content platforms keep holding content while Croct decides which version each visitor sees.
Commerce platforms forward store events automatically, so audiences reflect real shopping
behavior.

**B2B firmographic data.** [6sense](/integrations/6sense),
[Demandbase](/integrations/demandbase), [ZoomInfo](/integrations/zoominfo) and
[Clearbit](/integrations/clearbit). They identify the account. Croct adapts the value
proposition, the hero, the logo cloud and the testimonials to it in real time.

**Analytics and behavior.** [Google Tag Manager](/integrations/google-tag-manager),
[Google Analytics](/integrations/google-analytics), [Amplitude](/integrations/amplitude),
[Mixpanel](/integrations/mixpanel), [Microsoft Clarity](/integrations/clarity) and
[Contentsquare](/integrations/contentsquare). Events flow in from your data layer, and the
audiences, experiences and variants behind each session flow out to your reports and
recordings.

**CRM and marketing.** [HubSpot](/integrations/hubspot). Form submissions become goals, form
fields enrich profiles, and an experiment can decide which form a visitor sees.
