No Dockerfile
The platform detects Astro from package.json, picks the build and start commands, and lists the environment variables your code reads.
Astro deploy guide · Agent Lab Deploy
Deploy Astro
in one sentence.
Upload your Astro project as it is — no Dockerfile — or tell Claude Code, Codex or Cursor "deploy this". Agent Lab builds it into a web service, or a static web page when it is fully static, gives every version a preview URL with rollback, and checks uploads for leaked keys. Apps and databases run on Google Cloud in Taiwan.

Why deploy Astro on Agent Lab
Astro online without running a server yourself
JavaScript / TypeScript project, built from source with no Dockerfile, deployed as a web service, or a static web page when it is fully static.
Preview, go live, roll back
Every upload is a new version with its own URL. Look first, then go live; switch back to any version in one click.
Leaked keys caught
Uploads are checked for API keys and credentials before they can go live. Secrets go in the console, never in the code.
PostgreSQL in one click
Create a database and connect it; the connection is written into the app's environment and the password is never shown.
Your options
Astro on Agent Lab, or on your own VPS
Scroll the table sideways.
| What you care about | Agent Lab Deploy | Your own VPS |
|---|---|---|
| Setup | Upload or say one sentence; no Dockerfile | SSH, a runtime, a process manager, a reverse proxy |
| HTTPS and domains | Automatic, custom domains on paid plans | Certbot and DNS by hand |
| Preview and rollback | Every version has its own URL; roll back in one click | Write your own scripts |
| Before going live | Uploads checked for leaked keys | Nothing unless you set it up |
| Database | PostgreSQL in one click, connection written into the app | Install and back it up yourself |
| Cost to start | Free plan: NT$0, one size-S app (sleeps when idle) | A VPS at roughly NT$200–600 a month, plus your time |
Steps
Deploy Astro in four steps
Prepare
Keep package.json at the top of the project and commit the lockfile. Leave out node_modules, .git, dist and .env.
Upload or ask
Drop the folder on a project's Deploy tab, push from GitHub, or ask your AI tool through Agent Lab MCP.
Build and check
The platform builds the version and checks it for leaked keys. Enter any secrets it lists in Settings.
Preview and go live
The first version goes live once it builds. Later ones get a preview URL; go live when you're happy.
Setup
What Agent Lab runs for Astro
Most Astro sites (blogs, docs, marketing pages) are fully static and deploy as a web page on the CDN, with no server to run. When you need SSR or API endpoints, add @astrojs/node with mode: "standalone" and it deploys as a web service.
Build and start

Or ask your AI tool
Read https://app.agentlab.cresclab.com/agent/deploy.md and deploy this Astro project to Agent Lab. Show me the build plan and the environment variables it needs first, tell me where to enter any secrets, and wait for my OK before it goes live.FAQ
Deploying Astro: questions
Do I need a Dockerfile to deploy Astro?
No. Upload the Astro project with package.json at the top and Agent Lab detects the framework, builds it and starts it. A Dockerfile at the top, if there is one, is used instead. Docs →
Does an Astro site need a paid plan?
A static Astro site fits the Free plan (3 static web pages included). An SSR web service runs on Free as one size-S app that sleeps after 15 idle minutes; upgrade to Pro to keep it running or add a custom domain.
Where do API keys and other secrets go?
In the project's Settings, under Secrets; the code reads them as environment variables. Random values such as session secrets can be generated in the console without anybody seeing them. A key found in an upload stops it before it goes live.
Can I deploy Astro from Claude Code or Codex?
Yes. Connect Agent Lab MCP once (one command, sign in in the browser, no API key), then say "deploy this Astro app". The tool creates the project, uploads, waits for the build and asks before going live. Connect MCP →
Is there a free way to host Astro?
The Free plan is NT$0: one size-S app that sleeps after 15 idle minutes, one size-S database, three static web pages, 100 build minutes and 5 GB of traffic a month, pausing at the limit instead of charging. Pro (US$29 a month before tax) keeps apps running and adds custom domains. Pricing →
