Question 1

What is vibe coding, and how does it actually work on Replit?

Accepted Answer

Vibe coding is a development approach where you describe what you want to build in plain English and an AI agent writes the code for you. On Replit, vibe coding works through Replit Agent. You describe your app, and the Agent plans the architecture, selects a tech stack, writes the code, sets up the database, and deploys your app.

Question 2

Why is Replit Agent so expensive, and how can I reduce my vibe coding costs?

Accepted Answer

Replit Agent pricing reflects the power of the AI models running behind each prompt. Reduce costs by using the basic Assistant for simple tasks, writing specific detailed prompts, breaking work into small focused tasks, setting spending limits, and monitoring token usage.

Question 3

How do I write better prompts for Replit Agent to get the results I want?

Accepted Answer

Plan before you prompt, be surgical not sweeping, specify what NOT to change, reference existing files, use incremental builds, and include acceptance criteria. Effective prompting is the single biggest factor in successful vibe coding on Replit.

Question 4

How do I deploy my Replit app to a custom domain?

Accepted Answer

Deploy your app through Replit's deployment feature, go to Custom Domain settings, add the DNS records Replit provides to your domain registrar, and wait for DNS propagation and verification which can take 24 to 72 hours.

Question 5

Can I build native iOS and Android mobile apps with Replit and vibe coding?

Accepted Answer

Yes. Replit supports mobile app development through Expo (React Native). Several vibe coders have successfully published apps to both the App Store and Google Play entirely through Replit Agent using Expo's build service (EAS Build).
