# Atoti product dependencies and version compatibility

> How the Atoti Java SDK and Atoti Python SDK relate to downstream products such as Atoti UI, shown through per-product compatibility tables keyed by each product's own version, with links to further changelog and dependencies details.

Compatible versions matter when combining or upgrading Atoti products.
This page lists compatible versions for every Atoti product, from the core SDKs up through Atoti UI, workflow products, and packaged solutions.

## How do Atoti products depend on each other?

* **[Atoti Java SDK](./engine/java-sdk/6.2/intro/overview)** contains the core Atoti engine and is the primary way to build Atoti sessions. Every other product listed here depends on it, directly or through a bundled solution.
* **[Atoti Python SDK](./engine/python-sdk/6.2/index)** also contains the core Atoti engine, and is an alternative way to build Atoti sessions without writing Java.
* **[Atoti UI](./data-visualization/atoti-ui/5.2/introduction-to-atoti-ui)** is the user interface for an Atoti project.
* **[Atoti Admin UI](./engine/admin-ui/5.2/introduction-to-admin-ui)** is a separate administration interface for the Atoti Java SDK.
* **[Atoti Intelligence](./atoti-intelligence/6.2/intro/intro)** adds AI features (chat, Auto-Explain, and related tools) on top of the Atoti Java SDK and Atoti UI.
* **[Atoti Limits](./atoti-intelligence/workflows/limits/6.2/introduction-to-atoti-limits)** is a workflow product that depends on the Atoti Java SDK and Atoti UI.
* **[Atoti Sign-Off](./atoti-intelligence/workflows/signoff/6.2/introduction-to-atoti-signoff)** is a workflow product for approvals. It depends on the Atoti Java SDK and Atoti UI.
* **Solutions** including Atoti Enterprise Risk depend on the Atoti Java SDK and Atoti UI. Some solutions also depend on other workflow products.

## Which versions of Atoti products are compatible?

The compatibility tables use this key:

* **`≥`**: The listed version is a minimum required version, not an exact release.
* **`X.Y.x`**: Any patch release within that minor version line, e.g. `6.2.x` means any `6.2` release, such as `6.2.0` or `6.2.1`.
* **`X.Y–X.Z`**: Any version within that range.
* **`-sb3`**: The Spring Boot 3 build variant of that release, e.g. `6.0.x-sb3` is the Spring Boot 3 variant of Atoti Java SDK 6.0.x.
* **`–`**: This dependency didn't exist yet for that release, so no version applies.

### Atoti Python SDK

Atoti Python SDK embeds a specific Atoti Java SDK build, plus its own JDK, instead of requiring a separate Java installation.
The embedded version still matters for two reasons:

1. **Security review**: identifies the actual engine code and JDK running underneath, including their patch level.
2. **Development**: determines which [Atoti Java SDK](./engine/java-sdk/6.2/intro/overview) capabilities and configuration options are available when switching to Java.

| Atoti Python SDK | Atoti Java SDK |
| ---------------- | -------------- |
| 6.2.x            | 6.2.x          |
| 0.9.x            | 6.1            |

* See the [Atoti Python SDK changelog](./engine/python-sdk/6.2/changelog) for more details.
* See the [Atoti Python SDK dependencies page](./engine/python-sdk/6.2/dependencies) for other dependencies, such as required Python and third-party package versions.
