Cursor Vibe Coding: Build and Publish in One Session
You're a freelance consultant who needs a client-facing project page by tomorrow morning. You don't have a designer. You don't have a developer. You have Cursor open on your laptop and a rough idea of what the page should say. Here's what to do.
Cursor vibe coding is the workflow where you describe what you want in plain English, and Cursor's Agent mode writes, edits, and runs the code for you. Andrej Karpathy coined the term "vibe coding" in early 2025 to describe this exact dynamic: you steer, the AI builds. Cursor is one of the best tools for it because of how tightly it integrates AI models into a real code editor. If you're new to the concept, the full breakdown of what vibe coding is covers the origin story and how it differs from traditional development.
The Old Way vs. the Cursor Way
Building a one-off page used to mean one of two things. Either you opened a website builder, spent an hour fighting a template that almost fit your needs, and settled for "close enough." Or you opened VS Code, wrote HTML from scratch, figured out hosting, wrestled with DNS, and burned half a day on what should have been a 30-minute task.
With Cursor's Agent mode, you describe the page in a chat panel. "Build me a single-page site for a consulting engagement. Hero section with my name and title, a three-column section for services, a contact form at the bottom. Clean, modern, dark background." Cursor generates the HTML and CSS in your editor. You see the code as it's written. You make adjustments by talking, not by hunting through line numbers.
The code is yours. That matters. You're not locked into a proprietary editor. You're not renting a template. You have an HTML file that works anywhere.
What You Need
- Cursor (free Hobby plan works, Pro at $20/mo gives you more AI requests)
- A clear description of what you want (two to three sentences is enough to start)
- HTMLPub account (free tier gives you 5 pages) for publishing
- 10 to 30 minutes, depending on how many revisions you want
That's the full stack. No frameworks to install. No build tools. No deployment pipeline.
The Workflow: Prompt to Published
Step 1: Open Cursor and Start an Agent Chat
Create a new project folder. Open the Agent chat panel (Cmd+I on Mac, Ctrl+I on Windows). This is where you'll do everything. Agent mode doesn't just autocomplete code. It creates files, edits across multiple files, runs terminal commands, and iterates based on your feedback.
What you should see: An empty project folder and a chat panel ready for input.
Step 2: Describe Your Page
Be specific about structure, not about code. Good prompt: "Build a single-page HTML site for a freelance copywriter. Include a hero section with a headline and subhead, a portfolio section with 4 project cards, a testimonials area with 2 quotes, and a contact form. Use a sans-serif font, lots of white space, and a blue accent color."
Cursor will generate an index.html file, probably with inline CSS or a linked stylesheet. It will ask clarifying questions if your prompt is ambiguous.
What you should see: A complete HTML file in your editor. Preview it with Live Server or just open the file in your browser.
Step 3: Iterate by Talking
This is where vibe coding earns its name. Look at the preview. Something feels off about the spacing? Tell Cursor: "The portfolio cards need more padding and the testimonial section feels cramped. Add 40px of vertical margin between sections." Cursor makes the edits in place.
Want to add a section? "Add a pricing table below the portfolio with three tiers: Basic at $500, Standard at $1,200, and Premium at $2,500." It writes the HTML and styles it to match the existing design.
What you should see: Your page evolving with each prompt. Each change takes 10 to 30 seconds.
Step 4: Get It Live
You have a finished HTML file. Now it needs a URL. Copy your HTML and paste it into HTMLPub. You get a live URL in about 60 seconds. Custom domain if you want one. SSL included. Forms work out of the box.
If you want an even faster loop, HTMLPub has an MCP connector that lets you publish directly from your AI conversation. Build in Cursor, push to HTMLPub from your terminal or Claude session, see it live without switching tabs.
What you should see: Your page at a real URL, with working forms and a valid SSL certificate.
Step 5: Revise and Republish
Client wants changes? Open Cursor, tell Agent mode what to adjust, copy the updated HTML back into HTMLPub. The whole revision cycle takes minutes, not hours. This is what makes vibe coding practical for beginners and experienced builders alike: the feedback loop is tight enough that iteration feels effortless.
Common Issues (and What to Do)
Cursor generates React or Next.js when you wanted plain HTML. This happens if you don't specify. Start your prompt with "Build this as a single static HTML file with inline CSS. No frameworks, no build step." Cursor follows instructions well when they're explicit.
The design looks good on desktop but breaks on mobile. Add to your prompt: "Make it fully responsive. Stack the columns on screens under 768px." Cursor knows responsive patterns. You just have to ask.
Your HTML pastes into HTMLPub but the images don't show. Cursor often references local file paths for images. Before publishing, switch to web-hosted images. Use Unsplash URLs or upload your images to HTMLPub's asset library. Replace src="./images/hero.jpg" with the hosted URL.
What You Actually Get
A page that took 15 to 25 minutes to build. Code you own and can edit later. A live URL you can share with clients, put on a business card, or link from your LinkedIn. No monthly design tool subscription. No waiting on a developer. No "close enough" template compromises.
Cursor handles the syntax. HTMLPub handles the hosting. You handle the thinking.
If you're comparing Cursor to other vibe coding tools, Lovable takes a different approach with a more visual, app-focused workflow. Cursor gives you more control because you're working in a real editor with the full file system in front of you.
