# Integrations

> Connect best-in-class tools to your Rey app — no code required. Monetize with RevenueCat, track growth with AppsFlyer, and analyze users with PostHog.

Rey integrations let you connect best-in-class third-party tools to your app without writing a single line of code. Each integration is built directly into the Rey editor, so you can activate, configure, and start using powerful external services in minutes — not days.

## Integration Categories

Rey's integrations are organized into three categories that cover the full lifecycle of a successful app: getting users, making money, and keeping them coming back.

* **Monetization** — Add paywalls, manage subscriptions, and track revenue.
* **Growth** — Attribute installs to campaigns and measure marketing ROI.
* **Retention** — Understand user behavior, watch session replays, and improve your product.

## How to Access Integrations

Open your project in the Rey editor, then open the **Integrations** panel from your project settings. Each integration card shows its connection status and a quick-access button to open its settings. You can enable or disable any integration at any time without affecting your app's other functionality.

<Note>
  All integrations are available on every paid Rey plan — Starter, Grow, and Scale. No integration is gated behind a higher tier.
