Astro builds static HTML by default, and writes every page to dist.

Setting	Value
Build command	`npm run build`
Output directory	`dist`

Deploy your site

Bunny CLI
Manually

bunny sites is in Public Preview and available only in the Bunny CLI. It’s in active development, so commands, flags, and behaviour may change. Share feedback on Discord. The storage zone and pull zone behind each site appear in the dashboard under Storage and CDN.

Install the Bunny CLI and log in

curl -fsSL https://cli.bunny.net/install.sh | sh
bunny login

See Installation for npm and other options.

Create a site

From your project root, run:

bunny sites create my-site

Replace my-site with a name for your site. The CLI creates a storage zone for your files and a pull zone to serve them, then links this directory to the new site. The site is served at a b-cdn.net address, and the CLI prints the URL.

Build and deploy

bunny sites deploy --build

The CLI runs the build command, uploads the output directory from the table above, and publishes it. Every deploy is kept, so you can roll back with bunny sites deployments publish --previous.

Deploy on every push (optional)

bunny sites ci init

This writes a GitHub Actions workflow to .github/workflows/bunny-sites.yml that deploys the site on every push to main. Add your API key to the repository as a BUNNYNET_API_KEY secret. The CLI offers to run gh secret set BUNNYNET_API_KEY for you.

Build your site

From your project root, run npm run build. The build writes your site to the output directory listed in the table above.

Create a storage zone

In the bunny.net dashboard, go to Storage and click Add Storage Zone. Give it a name, pick the main region closest to your audience, and click Add Storage Zone.

Upload your files

Open the storage zone’s file manager and upload the contents of your output directory to the root of the zone. To script uploads, use the Storage HTTP API.

Create a pull zone

Go to CDN and click Add Pull Zone. Set Origin Type to Storage Zone, select the zone you created, and click Add Pull Zone.Your site is live at https://<pull-zone-name>.b-cdn.net.

Resize images with Bunny Optimizer

Astro’s <Image> component can hand every width to Bunny Optimizer through a custom image service. The build then skips image processing, and the edge resizes each width in the srcset.

Turn on Optimizer

bunny sites create leaves query strings and Optimizer off, so open the site’s pull zone under CDN → Pull Zones:

Turn on URL Query String vary, so each ?width= gets its own cache entry.
Enable Bunny Optimizer, then turn on the Dynamic Image API and automatic WebP under Optimizer → Settings. Your build has already minified CSS and JavaScript, so turn Optimizer’s minification off.

Add the image service

The service spreads Astro’s baseService, so Astro still works out the srcset widths, and only getURL changes. The example app has the full setup.

src/bunny-image-service.ts

import type { ExternalImageService } from "astro";
import { baseService } from "astro/assets";

const service: ExternalImageService<{ baseURL?: string }> = {
  ...baseService,
  getURL(options, imageConfig) {
    const base = imageConfig.service.config?.baseURL;
    const src = typeof options.src === "string" ? options.src : options.src.src;

    const absolute = /^(https?:)?\/\//.test(src);
    if (absolute && !(base && src.startsWith(base))) return src;

    const url = new URL(src, base || "http://localhost");
    if (options.width) url.searchParams.set("width", String(options.width));
    url.searchParams.set("quality", String(options.quality ?? 75));
    return base || absolute ? url.href : url.pathname + url.search;
  },
};

export default service;

astro.config.mjs

import { defineConfig } from "astro/config";

export default defineConfig({
  image: { service: { entrypoint: "./src/bunny-image-service.ts" } },
});

Add images

Import images from src/assets, or reference files in public by path:

---
import { Image } from "astro:assets";
import photo from "../assets/photo.jpg";
---
<Image src={photo} alt="Photo" layout="constrained" />
<Image src="/images/banner.jpg" alt="Banner" width={1200} height={600} layout="constrained" />

layout picks the srcset widths, and each one becomes a URL such as /_astro/photo.a1b2c3.jpg?width=828&quality=75. The build copies each image once and resizes nothing.

Add a custom domain

With the Bunny CLI, add the domain to your site:

bunny sites domains add example.com

The CLI prints the CNAME record to create with your DNS provider. Once the record resolves, issue a free certificate with bunny sites domains ssl example.com. For a manual deploy, add the hostname to your pull zone by following Custom hostnames.
