The best way to learn Claude Code is by building real things. Not toy demos — actual, useful projects that solve problems. Here are 12 examples drawn from projects we’ve built at Markana Media, complete with the prompts and workflows you can replicate.
1. Build a Complete Marketing Website
The prompt: “Build a marketing website for a digital agency. Homepage with hero section, services grid, client testimonials, and CTA. About page, services page with 5 service detail pages, contact page with a working form, and a blog. Use Next.js with Tailwind CSS. Dark theme with coral accents.”
What Claude Code builds: Complete Next.js project with all pages, responsive design, dark mode styling, contact form with validation, blog with markdown support, SEO meta tags, and structured data. Deployable in a single session.
Follow-up: “Add a blog CMS that reads from markdown files in a /content directory. Each file should have YAML frontmatter for title, date, excerpt, and category. Generate a sitemap.xml automatically.”
2. WordPress Custom Theme
The prompt: “Create a WordPress theme from scratch for a food blog. Include: custom recipe post type with structured schema.org/Recipe data, recipe archive page, category filtering, a homepage with a hero section and latest recipes grid, and responsive mobile design.”
What Claude Code builds: Full WordPress theme with functions.php, template files, custom post type registration, REST API endpoints, CSS, and schema.org structured data. Every recipe automatically gets rich snippet markup for Google.
Why this matters: Custom WordPress themes typically cost $2,000-$10,000 from a freelancer. Claude Code builds production-quality themes in hours. We’ve built two production themes this way — website development is one of our core services.
3. REST API With Authentication
The prompt: “Build a REST API using Express.js with JWT authentication. Endpoints: user registration, login, profile CRUD, and a protected admin route. Use PostgreSQL via Prisma. Include input validation, rate limiting, and proper error handling.”
What Claude Code builds: Complete API with routes, controllers, middleware, database schema, migration files, authentication logic, and input validation. It also writes Postman-compatible API documentation and basic tests.
Follow-up: “Add a password reset flow that sends a reset link via email using SendGrid. The link should expire after 1 hour.”
4. CLI Tool for Daily Tasks
The prompt: “Build a CLI tool in Python that helps me manage my blog. Commands: ‘new’ creates a new post draft from a template, ‘publish’ pushes a draft to WordPress via REST API, ‘stats’ shows traffic data from GA4, and ‘images’ generates featured images for posts that don’t have them.”
What Claude Code builds: A full CLI application using Click or Typer, with subcommands, configuration management, API integrations, and helpful error messages. The tool saves hours of manual work every week.
This is a pattern: Any workflow you do repeatedly can become a CLI tool. Claude Code builds them in minutes.
5. Automated Email Notification System
The prompt: “Build a notification system that monitors our website for changes and sends alerts. Check: uptime every 5 minutes, SSL certificate expiry weekly, new Google Search Console errors daily, and page speed scores weekly. Send summaries via email and alert immediately for downtime.”
What Claude Code builds: A monitoring script that runs on a schedule, checks each health metric, and sends formatted email reports. It includes retry logic for flaky checks and escalation rules for critical issues.
6. Data Dashboard
The prompt: “Build a marketing dashboard that shows our key metrics. Pull data from GA4, Google Ads, and Meta Ads Manager. Display: sessions, conversions, ad spend, ROAS, cost per lead, and top-performing pages. Include date range filters and comparison to the previous period. Use React with Recharts.”
What Claude Code builds: A full dashboard application with API integrations, data fetching, chart visualizations, filter controls, and period-over-period comparisons. Deployable as a standalone app or embedded in an existing admin panel.
Agency use case: We build client dashboards that pull from all their marketing channels into a single view. It’s one of the most requested deliverables in our analytics and tracking services.
7. Social Media Content Generator
The prompt: “Build a system that turns blog posts into social media content. When I give it a blog post URL, it should generate: a Twitter thread (5-7 tweets), a LinkedIn post, an Instagram caption with hashtags, and a YouTube Shorts script. Each should be adapted for the platform’s audience and format.”
What Claude Code builds: A script that fetches the blog content, parses it, and uses the Claude API to generate platform-specific versions. Each output follows platform best practices for length, format, and engagement patterns.
Automation extension: “Make this run automatically when a new post is published on WordPress. Use a webhook to trigger generation and save the outputs as a JSON file linked to the post.”
8. Chrome Extension
The prompt: “Build a Chrome extension that helps with SEO analysis. When clicked on any page, it should show: title tag, meta description, H1-H6 structure, image alt text audit, internal/external link counts, and schema markup detected. Display in a clean side panel.”
What Claude Code builds: Complete Chrome extension with manifest.json, content scripts, popup UI, and page analysis logic. Install it locally in developer mode and start using it immediately.
9. Webhook-Based Integration
The prompt: “Build a webhook server that connects Stripe to our CRM. When a payment succeeds, create/update the customer record, send a welcome email, add them to the onboarding email sequence, and post a notification in our Slack channel.”
What Claude Code builds: Express server with webhook endpoint, Stripe signature verification, CRM API integration, email service connection, and Slack notification. Includes error handling for each integration point and retry logic for failed API calls.
10. Automated Report Generator
The prompt: “Build a weekly report generator for our clients. It should pull GA4 data, Google Ads data, and Search Console data, calculate KPIs (sessions, conversions, ROAS, organic traffic growth, keyword rankings), generate a PDF report with charts and commentary, and email it to the client every Monday at 9 AM.”
What Claude Code builds: Data fetching scripts, KPI calculation logic, PDF generation with charts (using a library like PDFKit or Puppeteer), and an email scheduler. The commentary is generated by Claude API based on the data trends.
11. Content Migration Tool
The prompt: “Build a tool that migrates blog posts from Squarespace to WordPress. It should: export all posts from the Squarespace XML, parse them, convert the HTML to WordPress block format, preserve categories and tags, download and re-upload images to WordPress media library, and create the posts via REST API maintaining the original publish dates.”
What Claude Code builds: A migration script that handles the complete content transfer — XML parsing, HTML conversion, image downloading, WordPress API calls, and progress tracking. This kind of migration project typically costs $1,000-$5,000 from a freelancer.
12. Full E-commerce Checkout Flow
The prompt: “Build a checkout flow for our digital product store. Include: product listing page with filtering, cart with quantity management, checkout form with Stripe integration, order confirmation page, and email receipt. Handle tax calculation and discount codes.”
What Claude Code builds: Complete e-commerce frontend and backend — product display, cart state management, Stripe payment processing, order storage, email notifications, and discount code validation. A functional store built in a single day.
The Pattern Behind Every Example
Notice the pattern across all 12 examples:
- Describe the outcome — what you want the finished product to do
- Be specific about integrations — name the APIs, services, and data sources
- Include acceptance criteria — what “done” looks like
- Iterate conversationally — add features and refine through follow-up prompts
This is the vibe coding workflow in action. You describe, Claude Code builds, you review, you iterate. Every project above was built by a real team using this approach — nothing hypothetical.
