No code changes
React + Vite + TypeScript: the platform detects it and picks the build and start commands.
Deploy a Lovable app · Agent Lab Deploy
Built it in Lovable?
Put it online yourself.
Connect GitHub in Lovable and the code syncs to your repository. Link the repository in Agent Lab or upload the zip — no code changes, no Dockerfile. Agent Lab detects the framework, builds it, gives every version a preview URL and checks uploads for leaked keys.

Why deploy from Lovable to Agent Lab
Your Lovable project, not tied to Lovable
Preview, go live, roll back
Every upload is a new version with its own URL. Look first, then go live; switch back in one click.
Leaked keys caught
Uploads are checked for API keys and credentials before they can go live.
PostgreSQL in one click
Create a database and connect it; the connection is written into the app.

Scroll the table sideways.
| What you care about | Agent Lab Deploy | Your own server |
|---|---|---|
| Setup | Link the repository or upload the zip | SSH, a runtime, a process manager, a reverse proxy |
| Credentials | Secrets in the console, never in the code | Copied onto the server 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: US$0, one size-S app (sleeps when idle) | A VPS at roughly US$6–20 a month, plus your time |
Steps
Deploy from Lovable in four steps
Export from Lovable
Connect GitHub in Lovable and the code syncs to your repository.
Link or upload
Link the GitHub repository to a project, drop the zip on its Deploy tab, or open the folder in Claude Code and say "deploy this".
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 a Lovable project
A Lovable project is Vite + React and deploys as a static web page on the CDN; routes answer with index.html on reload, so they never 404. If the backend is on Supabase, the data stays there and the page keeps talking to it.
Build and start
# Agent Lab 偵測到 Vite + React 後執行
# What Agent Lab runs once it detects Vite + React

Deploying from Lovable: questions
How do I deploy a Lovable project?
Connect GitHub in Lovable and the code syncs to your repository. Then link the repository in Agent Lab or upload the zip; the platform detects the framework and builds it, with no Dockerfile. Deploy from GitHub →
Where do API keys and other secrets go?
In the project's Settings, under Secrets; server code reads them as environment variables. Anything in a VITE_ or NEXT_PUBLIC_ variable ends up in the page, so never put a secret there.
Can I keep editing in Lovable after deploying to Agent Lab?
Yes. Lovable's changes sync to GitHub and Agent Lab builds a new version from the same repository; each one gets a preview URL before it goes live.
Which frameworks does it support?
JavaScript, Python and Go projects build from source with no Dockerfile (Next.js, Vite, Nuxt, SvelteKit, Express, FastAPI, Django, Go and more); anything else ships a Dockerfile. All deploy guides →
Is there a free way to deploy?
The Free plan is US$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 →
