Your first deploy

Deploy a Next.js app from the dashboard or through your AI agent, then open its public URL to check the result. Choose UI or MCP on any step; the choice applies to the whole page.

Prerequisites

A Next.js app in a git repo. Any GitHub repo works; a fresh create-next-app is fine.
For the agent path: the Lessly MCP installed in your agent — see Install — and your agent open and connected to your Lessly workspace.

Step 1 — Connect your repo

In app.lessly.com, create a new app and connect the GitHub repo you want to deploy.

Open your repo in your agent. In Claude Code, that means cd into the project and start a session. In Claude Desktop or Cursor, open the project folder.

Step 2 — Deploy

Choose the branch to ship (main) and click Deploy. Lessly detects Next.js, picks the build command, and streams the build log as it runs.

Paste this into your agent:

Deploy my main branch to production.

The agent calls deployment_service_create — it reads your repo, detects Next.js, picks the right build command, and starts the deploy, streaming status as the build runs. The agent needs a token with deploy access to the app.

Step 3 — Verify the site is live

When the agent reports success, ask:

What's the URL of my latest deployment?

The agent checks the deployment with deployment_deployment_get and looks up the service’s public URL. Open that URL in your browser and check that the app loads.

What you just did

You deployed your app to production and opened its public URL to check that it works.

What to do next

“Promote this deploy to the apex domain.”
“Set the DATABASE_URL environment variable on production.”
“Show me the build logs for the last failed deploy.”
