How to deploy a SvelteKit app | Ample

The short version

To deploy a SvelteKit app on Ample, run ample deploy . --name <app-name> --public in the project directory, or ask your coding agent to deploy it to Ample. Ample builds it on the node-22 template, starts it with npm run start and returns a public HTTPS URL.

Deploy SvelteKit

1. 1

Ask your coding agent

Install the Ample CLI and create an account (no browser or card needed), then ask Claude Code, Codex, Cursor or any agent with a shell to deploy the project. See Ample for coding agents.

curl -fsSL https://get.ample.computer/install.sh | sh
ample auth signup
# then, in your agent:
# "Deploy this SvelteKit app to Ample"

2. 2

Or deploy from the CLI

Run the deploy once from the project directory. It waits until the app is live or failed and prints the URL; exit 0 is live, 1 failed, 2 needs input.

ample deploy . --name <app-name> --public

3. 3

Or use MCP

Agents connected to the Ample MCP server (https://api.ample.computer/mcp, or ample mcp over stdio) call ample_deploy with the same arguments.

4. 4

Verify

Open the URL. If the deploy failed, read the build log, then the runtime log, fix the cause and deploy again.

ample logs <deployment_id> --kind build

What Ample runs

| Template | node-22 | | Install | npm install | | Build | npm run build --if-present | | Start | npm run start | | Tested size | s-1vcpu-1gb |

Use @sveltejs/adapter-node and start the build with node build; it reads PORT and HOST. Ample detects the runtime, installs dependencies, runs the build when present and starts the app on the node-22 template behind a public HTTPS URL.

Last verification (September 20, 2026): SvelteKit app with adapter-node deployed on node-22 and rendered the expected page.

Before you deploy

You need

• A package.json with build and start scripts
• A server that listens on process.env.PORT and 0.0.0.0
• An Ample account token with servers:write

Know the limits

• Verified on the node-22 template at s-1vcpu-1gb; other templates and sizes are not verified by this recipe.
• adapter-node only; adapter-auto and other adapters are not verified.

Frequently asked questions

Do I need a Dockerfile to deploy SvelteKit?

No. Ample detects SvelteKit from the repository and builds it from source on the node-22 template. Dockerfile build steps are not run.

How do I add a database to a SvelteKit app?

Leave DATABASE_URL unset and deploy: when the code needs Postgres, MySQL, Redis or MongoDB, Ample creates a managed database and passes its connection string to the app. See Connect Postgres for SvelteKit.

What does it cost to host a SvelteKit app on Ample?

The Free plan runs 2 apps at once with no card and a hard monthly budget, so it never bills you. Larger needs are priced on volume; see pricing.

What if the deploy fails?

ample deploy waits until the app is live or failed. A failure returns who must act, a diagnosis and a suggested fix; read the logs with ample logs <deployment_id> --kind build. See Diagnose deployment failures for SvelteKit.
