# Hosting Compatibility

> See which runtimes and hosting patterns work well for Open Chat Widget agents.

Agents built with AI SDK are compatible with any Node.js environment. Some common hosting patterns:

* **Express** — [Railway](https://railway.app), [Render](https://render.com), [Fly.io](https://fly.io), or any Node host (VPS, Docker).
* **Hono** — [Vercel](https://vercel.com) (Node or Edge), [Cloudflare Workers](https://workers.cloudflare.com), or a Node host.
* **Vercel** — Next.js API routes or standalone serverless functions using the AI SDK.
* **AWS** — [AWS Lambda](https://aws.amazon.com/lambda/) (e.g. with Serverless Framework or SST) with a Node runtime.

As long as the server exposes an endpoint, the widget will be able to connect to it.
