# What is Sandbox?

> An isolated, production-like environment for testing your World ID integration end-to-end.

Sandbox is a dedicated, production-like environment for building and testing your
World ID integration. It runs alongside Production as its own environment, with its
own backend and its own builds of the World ID app for iOS and Android, built from
the same codebase and release process as Production — so Sandbox is just as stable
and reliable.

It lets you run a complete integration — from your app or website, through IDKit, into
the World ID app, and back — without touching production identities or issuing real
proofs.

## Why use Sandbox

Sandbox is built for integration testing. It gives you:

* **A full end-to-end round trip.** Sandbox is a valid IDKit destination, so you can
  drive a real request from your surface into the World ID app and receive a proof
  back over the bridge — the same path your production integration will use.
* **Resettable accounts.** Delete an account and sign up again as often as you need.
* **Simulated verification.** Exercise verification flows without real hardware or
  real-world credentials.
* **Controllable gating.** You decide whether the system enforces fraud, risk, and
  attestation checks. Turn enforcement off to move quickly through integration testing,
  or turn it on to validate how your integration behaves under production-like gating.

## What you can test

The full relying-party journey from your surface into the World ID app and back:
request handoff, consent, capture, enrollment and matching, proof generation, and
delivery of the proof to your session.

Both same-device (deep link) and cross-device (QR) flows are supported, on both iOS
and Android sandbox builds.

## What Sandbox is not

* **Not production.** Accounts and proofs issued in Sandbox are for integration
  validation only — not load testing, security certification, or production sign-off.
* **Not a source of real uniqueness.** Sandbox does not represent real-world identity
  or uniqueness at scale.
* **Not published to the app stores.** The sandbox World ID builds are distributed
  directly to testers rather than through the App Store or Google Play. See
  [How to get access](/world-id/sandbox/sandbox-access) for how to install them.
