+description: Architect runtime support documentation
+---
+
+## Overview
+
+This document outlines the current runtime support commitments Architect makes, both for official AWS Lambda runtimes (such as Node.js), and Architect-specific runtimes (such as TypeScript and Deno).
+
+
+## Runtime support definitions
+
+### Deployment
+
+Architect will deploy your function to AWS. Caveats:
+- If you are using a compiled language, such as .NET, you may be responsible for compiling your own handlers via custom scripts or [Architect plugins](/docs/en/guides/plugins/overview); however, once compiled, [Deploy](/docs/en/reference/cli/deploy) will ship your code.
+- Some runtimes may be supported by way of an Architect runtime plugin. For example, Architect supports Rust via its [official Rust plugin](https://github.com/architect/plugin-rust).
+
+
+### Sandbox
+
+Architect's local development environment, [Sandbox](/docs/en/reference/cli/sandbox), will execute your code locally in a fully-emulated Lambda. This may also include support for automatically compiling / transpiling handlers via plugin.
+
+
+### Runtime utils
+
+Architect authors and maintains a runtime utility library, such as [`@architect/functions`](/docs/en/reference/runtime-helpers/node.js) (Node.js) or [`architect-functions`](/docs/en/reference/runtime-helpers/python) (Python), with helpers for various Architect primitives (`@http` events, etc.), service discovery support, and more.
+
+
+### Automated dependency management
+
+Architect [Deploy](/docs/en/reference/cli/deploy) (via [Hydrate](/docs/en/reference/cli/hydrate)) can be relied upon to automatically install each handler's unique dependency tree without any manual management of per-handler dependency manifests (e.g. `src/http/get-index/package.json|requirements.txt`, etc.).

+¹ TypeScript supported via [official plugin](https://github.com/architect/plugin-typescript)
+
+² Deno support may not be current or stable due to ongoing issues related to [Deno compiling to AWS Linux](https://github.com/denoland/deno/issues/17925); an [in-development Deno utility library can be found here](https://github.com/architect/functions-deno)
+
+³ Rust supported via [official plugin](https://github.com/architect/plugin-rust)
+
+⁴ Go supported via [official plugin](https://github.com/architect/plugin-go)
