# Case studies

Results teams have published from running Croct across travel, banking, print, logistics,
education, and mobility.

## How it works

The pattern repeats across them: mark the content that should vary, build audiences from real
behavior, test the variants, and roll out what wins without waiting for a release.

## Building with it

Each of these started with a single slot. Adoption is gradual by design, so the first result
does not wait on 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

### How long before a team sees a result?

Setup is same-day for most teams, and the first experiment usually runs the same week.

### Do these require a large team?

No. After setup, experiments and experiences are run by marketing and CRO teams without
developer involvement.

### 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.
