Agenta

Your AI Cofounder for Building MVPs in Minutes

Comment

🚀 Inspiration

Every year, thousands of startup dreams never see the light of day. Non-technical founders struggle to prototype. Developers drown in boilerplate.

Agenta was born from a bold vision:

"What if anyone could turn a raw idea into a full-stack SaaS MVP — in minutes?"

As a solo founder, I set out to build this dream into reality in just 1.5 days. Agenta empowers dreamers to become doers — by removing the hardest part: writing all that code from scratch.

✨ What it does

Agenta is an AI-powered SaaS MVP Generator.

You give it your idea. It gives you a fully working codebase with:

  • 📂 Real project folder structure
  • 🧠 Smart, AI-picked features
  • 🔐 Auth-ready (Supabase)
  • ⚙️ Backend API routes
  • 🖼️ Frontend UI (Next.js + Tailwind + Shadcn)
  • 🧪 No fake logic. Real working code.

And all of this happens in real time, streamed file-by-file with a beautiful progress bar.

Once done, you can preview, manage, or download your ready-to-run ZIP — the entire SaaS MVP.

⚙️ Features

✅ AI-Powered Code Generator Built using GPT-4, Claude, and Mistral 8x7B via OpenRouter. Generates real, structured code.

✅ Live Streaming via SSE Watch your code being written, file-by-file — live. See names, sizes, line counts.

✅ Auth-Ready & Scalable Supabase-based auth with login, signup, sessions — pre-wired. Codebase is scalable and ready for extension.

✅ Prompt-Preserving Engine Agenta retains your raw startup idea and feeds it directly into model prompts to ensure the final product is on point.

✅ Instant Zip Download At the end, get the full project zipped and downloadable, ready to deploy locally or on the cloud.

✅ Modern UI Design Premium dark mode design built with Tailwind, Shadcn, and Framer Motion for a smooth, professional UX.

✅ MVP Manager Dashboard View, preview, and manage all generated MVPs in one place.

💪 How I built it

Stack:

  • Express.js — Backend controller + streaming logic
  • Next.js App Router — Modern frontend with server components
  • Supabase — Auth & MVP metadata
  • OpenRouter — GPT-4, Claude, Mistral
  • SSE — File streaming (Server-Sent Events)
  • Tailwind + Shadcn + Framer Motion — UI
  • TypeScript — Strict typing across full-stack

Architecture:

  • User submits a startup idea
  • AI selects features + generates code, file by file
  • Each file is streamed in real-time via SSE
  • All files are zipped and stored
  • Supabase stores prompt + metadata
  • Frontend displays progress, lets users download ZIP

🧷 Challenges I ran into

  • ⚡ Handling file streaming + zip compression simultaneously with async generators
  • 📡 Creating real-time SSE streaming with progress animations that stay in sync
  • 🧪 Making sure each file is complete, clean, bug-free
  • 🔀 Sending detailed prompt data while preserving user formatting
  • 🔍 Mapping user intent → features → clean code in an explainable architecture

🏆 Accomplishments I’m proud of

  • 📅 Built the full-stack platform — solo — in 1.5 days
  • 📡 Real-time, live code generation with SSE
  • 💎 Premium dark-themed UI with Framer Motion animations
  • 🔐 Supabase-based auth, metadata logging, download security
  • 🎒 Plug-and-play user flow — just input, wait, and download
  • 💯 All output code is real, no placeholders or filler

📚 What I learned

  • Streaming SSE data from backend to frontend in real-time
  • Prompt engineering across GPT-4, Claude, and Mistral
  • Managing file output and real-time UI animation smoothly
  • Building premium UX using Tailwind + Framer Motion
  • Architecting AI-first full-stack systems that scale and extend

🔮 What’s next for Agenta

🧠 AI Lab Let users tweak model parameters, choose stacks, and add/remove features.

📈 Investor Dashboard Auto-generate lean canvas, business projections, pitch deck snippets.

🚀 1-Click Deploy Add buttons to deploy directly to Supabase, Vercel, or Railway.

💪 In-App Editor with AI Suggestions Let users tweak generated code with inline LLM suggestions.

🌐 Template Marketplace Let the community create + share custom MVP templates.

🔝 Collab Prompting + Sharing Build MVPs together — live — and remix others’ prompts.

🧑‍🚀 Closing Thought

Agenta exists so that no founder’s vision ever dies due to a lack of code. Let’s give everyone the power to launch.
