Introducing Codeyst — AI Full-Stack Engineer

Every great app starts with an idea. But between that idea and a working product, there are usually weeks of setup — choosing frameworks, configuring environments, writing boilerplate, and debugging build tools. Most ideas never make it past this stage.

We built Codeyst to change that.

Describe It. Build It. Ship It.

Codeyst is an AI-powered development platform where you describe what you want to build, and a fully working application appears in front of you — in real time.

No setup. No boilerplate. No environment headaches. Just open Codeyst, type what you're thinking, and watch your app take shape.

Want a task management dashboard? A personal portfolio? An e-commerce storefront with a real database? Just say so. The AI writes the code, installs the packages, runs the project, and gives you a live preview — all while you watch.

Not Just Code Generation — Full-Stack Development

Most AI tools generate code snippets. Codeyst goes further. It's a full-stack AI engineer that follows a transparent, professional workflow:

• Understands your requirements — it analyzes your request, clarifies intent, and understands the "why" behind your idea.
• Plans the architecture — it breaks every task into a series of actionable, logical steps before writing any code.
• Implements precisely — it writes clean, modern code, installs dependencies, and configures your environment.
• Iterates with you — it listens to your feedback and refines your app exactly how you want it.

You see everything happening in real time — every plan made, every file created, and every change applied. It's like pair-programming with an expert engineer who never gets tired.

Real Full-Stack, Real Backend

This isn't just about pretty frontends. With Supabase integration, your apps get real backend superpowers:

• Database — store and query real data with PostgreSQL
• Authentication — add user sign-up, login, and access control
• Storage — handle file uploads and media
• Realtime — build live, collaborative features
• Edge Functions — add server-side logic

You can go from "I need a project management tool with user accounts and real-time updates" to a fully working app with a real backend — all through conversation.

Build for Web and Mobile

Start with a web app using a modern React stack that's ready for production. Or choose mobile to build cross-platform apps for iOS and Android with Expo — from a single codebase.

Both templates come fully configured with everything you need: routing, theming, UI components, and more. No setup guides, no configuration files to wrestle with.

Choose From the Best AI Models

Not every task needs the same level of intelligence. Codeyst gives you access to the latest, industry-leading AI models — so you can pick the right tool for the job:

• Use a fast model for quick edits and small changes
• Switch to a powerful model for complex, multi-file features
• Or let Auto mode choose the best one for you

You're always in control, and you can switch between models at any point during your project.

---

See Everything. Control Everything.

Codeyst isn't a black box. You get full visibility into what the AI is doing:

• Real-time streaming — watch files being created and modified live
• Live preview — see your app come to life as Codeyst builds it
• Built-in file explorer — browse, search, and edit (available for mobile templates) any file in your project
• Step-by-step progress — the AI shows its plan and marks progress as it works

Whether you're technical or not, you always know exactly what's happening with your project.

Ship to Production in One Click

Building is only half the journey. Codeyst integrates with the tools that get your app to users:

• Vercel — deploy your web apps to a global CDN instantly
• GitHub — push your code to a repository and keep it in sync
• Supabase — connect your backend services seamlessly

Go from idea to live on the internet without ever leaving Codeyst.

Bring Your References

Have a specific design in mind? Upload screenshots, mockups, images, or documents directly into the chat. The AI analyzes your references and builds to match — so the result looks exactly how you imagined it.

Who Is Codeyst For?

• Founders who want to validate ideas before hiring a team
• Designers who want to turn mockups into real, working apps
• Students building their first projects and learning by doing
• Freelancers who want to deliver faster without sacrificing quality
• Developers who want to skip the repetitive setup and focus on what matters

Start Building Today

The free plan gives you credits to start right away — no credit card required. When you're ready to build more, flexible plans scale with you.

Codeyst was built by Aadarsh Guru with a mission to democratize software creation. What began as a tool for rapid internal prototyping has evolved into a robust platform that empowers founders and developers to ship full-stack applications at the speed of thought. Today, Codeyst is dedicated to making building software as natural as describing it.
