🚀 Inspiration

As entrepreneurs working with digital products and AI automation, we often faced the same frustration: jumping between tools, building flows manually, and lacking a unified way to manage multiple AI agents with clear controls.
We wanted a system where business owners could build and deploy specialized GPT agents — and where usability, scalability, and monetization were built-in from day one. That’s how NEXUS OS was born.

🤖 What it does

NEXUS OS is a no-code SaaS platform for managing AI agents specialized in business and marketing tasks. It allows:

  • Creation of GPT-powered agents with custom instructions and capabilities
  • Subscription-based user access with plan-based limits (tokens, features, agents)
  • Real-time chat between users and agents using GPT-4o
  • Image generation via DALL·E for selected plans
  • Admin panel with analytics, plan management, and user control
  • Full integration with OpenAI (admin-provided API key)

🛠️ How we built it

  • Frontend: React + Tailwind CSS (via Lovable.dev for rapid UI design)
  • Backend: Supabase (PostgreSQL, Auth, Storage)
  • AI Integration: OpenAI API (GPT-4o for chat, DALL·E 3 for images)
  • Deployment: Hosted with Bolt + Vercel
  • Design: Figma + custom UX inspired by OpenAI’s own GPT builder
  • Code Repository: https://github.com/mavik-ai/mavik-nexus-os

🧗 Challenges we ran into

  • Implementing accurate token tracking for OpenAI usage
  • Designing a modular plan system that handles permissions and usage limits
  • Ensuring the admin panel was powerful but intuitive
  • Managing avatar/UX layout issues in collapsed sidebars
  • Adapting no-code tools to support real API integrations without overcomplicating logic

🏆 Accomplishments that we're proud of

  • Full multi-agent system working with real OpenAI integration
  • Functional admin dashboard with user + plan management
  • Seamless UX for agent creation inspired by ChatGPT's agent builder
  • Launch-ready MVP created in under 2 weeks
  • Sustainable pricing model based on usage and cost forecasting

đź“š What we learned

  • How to structure scalable SaaS logic inside no-code platforms
  • How to use Supabase efficiently for auth + relational data
  • That clean UX for admins is just as important as user features
  • Token tracking and usage logic is essential in AI products
  • Even with no-code tools, strong planning = smooth execution

đź”® What's next for NEXUS OS

  • Add Stripe integration for automated plan upgrades
  • Enable agent marketplace so users can publish/sell their own agents
  • Add analytics dashboards for agent performance and usage
  • Expand to support Claude, Gemini, and open-source models
  • Launch as a white-label platform for agencies and B2B clients
