Overview

This course connects Replit Agent with the everyday processes of Web Development. Participants work on realistic scenarios and leave with prompts, workflows and checklists they can use straight away.

Replit brings together a development environment, runtime, database and hosting in a single browser workspace. Replit Agent builds on top of that: you describe an application in plain language, and the agent drafts a plan, creates files, installs packages, sets up a database, starts the app and tests it on its own. In this one-day course you learn to steer that process deliberately, whether you are a professional developer, a product manager validating ideas, an educator, or a founder who needs a first product quickly.

You work on an application of your own, such as an internal tool, a small API, a data dashboard or an MVP with user accounts. Along the way you learn to state requirements clearly, use checkpoints for safe rollbacks, handle secrets and the database correctly and choose the right deployment type. For technically experienced participants we go deeper into code structure, Git integration and debugging in the shell. Finally, you take a realistic look at costs, security and limits, so that a quick prototype does not turn into an unmanageable production system.

Web development today covers far more than HTML, CSS and a bit of JavaScript: responsive layouts, accessibility, SEO, performance, forms, content management systems, APIs, hosting and deployment are all part of the job. In small teams and agencies especially, web developers have to cover all of it. AI coding assistants and agents are a huge lever here: they turn designs into layouts, write semantic HTML and modern CSS with grid and container queries, audit pages for accessibility and Core Web Vitals, build CMS templates and automate deployments. Vibe coding also makes rapid prototypes possible that used to take days. This course teaches you to combine that speed with clean structure, maintainability and quality assurance.

The course is delivered live – either online in a virtual classroom or on-site in our training rooms in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run it exclusively for your team.

Course outline

Module 1 The Replit workspace and Agent at a glance
  • Understanding the workspace: editor, preview, console, shell and files
  • How the agent works: plan, implementation, self-testing and clarifying questions
  • Agent versus Assistant for small, targeted changes
  • Recognising projects that suit Replit Agent and those that do not
Module 2 From idea to working app
  • Writing requirements as a short specification: users, features, data
  • Using plan mode to agree scope and approach up front
  • Extending the app in small steps and checking results in the preview
  • Using checkpoints and rollbacks when a change goes wrong
Module 3 Data, users and integrations
  • Creating the built-in PostgreSQL database, inspecting tables and editing data
  • Setting up sign-in and user management with Replit Auth
  • Storing API keys safely in Secrets rather than in code
  • Connecting external services such as payments, email or AI models
Module 4 Understanding code, debugging and collaboration
  • Reading the project structure: where frontend, backend and data logic live
  • Using console errors and logs and passing them back to the agent
  • Collaborating in real time and versioning projects with Git
  • Making targeted changes to Python and JavaScript projects without the agent
Module 5 Publishing, operations and limits
  • Choosing a deployment type: static, autoscale, always-on or scheduled
  • Setting up a custom domain, environment variables and monitoring
  • Estimating and capping costs for agent usage and hosting
  • Data protection, access rights and handover to a development team
Module 6 Practice lab: Web Development
  • Turning designs into layouts
  • Accessibility audit
  • Performance and Core Web Vitals
  • CMS templates and extensions
  • Technical SEO
  • Forms and integrations
Module 7 Data protection, quality & transfer to daily work
  • Websites are subject to GDPR, ePrivacy rules and, in many cases, accessibility legislation under the European Accessibility Act: generated code must not embed tracking or external resources without consent and must be checked for accessibility. Also watch the licences of fonts, images and code snippets, and keep hosting and CMS credentials out of prompts.
  • Ground rules for safe AI use in your team
  • Checking results: facts, sources, tests and the four-eyes principle
  • Personal action plan for the next 30 days
  • Open questions, outlook and resources for further learning

Practical scenarios from your field

Turning designs into layouts

From screenshots or design files, the assistant produces semantic HTML and modern CSS using grid, flexbox and custom properties, responsive across all breakpoints and consistent with existing stylesheets.

Accessibility audit

The AI checks pages for heading structure, alt text, form labels, keyboard operability and contrast, interprets automated test results and fixes findings against WCAG success criteria.

Performance and Core Web Vitals

Lighthouse reports are analysed, images converted to modern formats with responsive sources, critical CSS extracted, scripts deferred and layout shifts eliminated in a targeted way.

CMS templates and extensions

The agent builds themes, blocks or plugins for WordPress, TYPO3 or a headless CMS, including content models, templates and protection against common security flaws. The system’s coding standards are respected.

Technical SEO

The AI adds structured data, meta tags, hreflang annotations, readable URLs and XML sitemaps, and checks internal linking and canonicals for consistency. Broken redirects and duplicate content are uncovered.

Forms and integrations

Contact and enquiry forms are built with validation, spam protection and server-side processing, alongside integrations with newsletter, CRM or booking systems via their APIs. Errors and timeouts are handled cleanly.

Possible hands-on projects

Static website with a generator

A multilingual company website built with a static site generator, structured data, a sitemap and automated deployment through a CI pipeline.

Accessibility checker

A small tool that automatically audits a list of URLs, sorts findings by severity and generates a readable HTML report.

Appointment booking widget

An embeddable widget that loads available slots from an API, accepts bookings and triggers confirmation emails. The widget is accessible and fully responsive on all devices.

Prerequisites

Confident computer use and curiosity about software development are enough to get started. Programming experience in Python or JavaScript helps but is not required. Good knowledge of HTML, CSS and JavaScript plus some experience with Git, a CMS or a front-end framework.

Technical requirements

A laptop with an up-to-date browser and a Replit account; a paid plan is required for working with the agent and for deployments.

Data protection & compliance

Websites are subject to GDPR, ePrivacy rules and, in many cases, accessibility legislation under the European Accessibility Act: generated code must not embed tracking or external resources without consent and must be checked for accessibility. Also watch the licences of fonts, images and code snippets, and keep hosting and CMS credentials out of prompts.

Frequently asked questions

Can I attend without programming experience?

Yes. Replit Agent writes the code while you focus on requirements, testing and decisions. We explain the key concepts, such as database, API and deployment, in plain terms. Participants with programming experience get deeper dives into code structure and debugging, so both groups get real value from the day.

Who owns the code, and can I move away from Replit?

The generated code is a normal project in your workspace and can be pushed to your own repository via Git or downloaded. Moving to other infrastructure is possible but requires changes to the database, authentication and deployment setup. In the course we show you what to keep in mind from the start.

How do I keep costs under control?

Agent usage is billed by effort, and hosting is charged separately depending on deployment type and resources. Clear, incremental prompts, plan mode and using the Assistant for small tweaks reduce consumption considerably. We show where to monitor usage, how to set spending limits and which deployment type is cost-effective for your use case.

Can AI build an entire website for me?

For prototypes and simple sites, yes – and remarkably quickly. Production websites, however, need structure: clean components, verified accessibility, privacy compliance, performance and a well-designed deployment. On the course you learn to move AI-generated output into a maintainable project structure and safeguard it systematically.

Is the course suitable for career changers?

Yes, provided you have a grounding in HTML, CSS and JavaScript. AI explains code and concepts clearly and helps close knowledge gaps quickly. We make sure you understand the generated solutions and can evaluate them independently, rather than simply accepting whatever the assistant produces.

How much does “Replit Agent for Web Developers” cost?

The course costs a flat €949 plus VAT per participant – whether online or on-site. This includes 1 training day(s) with a live trainer, course materials, a lab environment and a certificate of attendance.

Can I suggest my own date?

Yes. Our suggested dates are just a guide. In the request form you can always describe your preferred date or period in free text – we check availability and confirm within one working day.

Is the course online or on-site?

Both are possible: live online in a virtual classroom or on-site in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart or Kaiserslautern. We can also run the course exclusively for your team.
