 SpacetimeDB is a database that is also a server.
 
-SpacetimeDB is a full-featured relational database system that lets you run your application logic **inside** the database. You no longer need to deploy a separate web or game server. [Several programming languages](#server-side-libraries) are supported, including C# and Rust. You can still write authorization logic, just like you would in a traditional server.

[Several programming languages](#module-libraries) are supported, including C# and Rust. You can still write authorization logic, just like you would in a traditional server.
 
 This means that you can write your entire application in a single language and deploy it as a single binary. No more microservices, no more containers, no more Kubernetes, no more Docker, no more VMs, no more DevOps, no more infrastructure, no more ops, no more servers. An application deployed this way is called a **module**.

-Technically, a SpacetimeDB module is a [WebAssembly module](https://developer.mozilla.org/en-US/docs/WebAssembly) that imports a specific low-level [WebAssembly API](/webassembly-api) and exports a small number of special functions. However, the SpacetimeDB [server-side libraries](#server-side-libraries) hide these low-level details. As a developer, writing a module is mostly like writing any other C# or Rust application, except for the fact that a [special CLI tool](/install) is used to build and deploy the application.

+Clients are written using the [client-side SDKs](#client-side-sdks). The `spacetime` CLI tool allows automatically generating code that works with the client-side SDKs to talk to a particular module.

+Clients are regular software applications that module developers can choose how to deploy (through Steam, app stores, package managers, or any other software deployment method, depending on the needs of the application.)
