April 2, 2026 I built Nexiun: A productivity ecosystem for developers (Next.js + Supabase) — Looking for early users!

Hi Indie Hackers!

I’m an engineering student and I just launched Nexiun. I built it because I was tired of having my workflow scattered across Notion, Jira, and various diagramming tools.

I wanted to create a single place where an idea can go from a visual concept to a technical execution without friction.

What you can do in Nexiun today:

  • 🧠 Idea Network: Forget flat lists. Use a node-and-edge canvas to create visual mind maps (supports text, voice, and groups).

  • 🛠️ For Devs (Database Diagrams): Design your Entity-Relationship diagrams and automatically get the SQL script ready to copy (Supports PostgreSQL, MySQL, and MariaDB).

  • 🚀 Project Management: Dynamic Kanban boards with integrated group chat, custom roles, activity tracking, and more!

  • ✅ Tasks & Interconnectivity: Centralize personal and group project tasks in a single list view. Each task supports subtasks and dynamic movement. Plus, you can convert any note into a task with just one click.

  • 🔥 Habit Tracking: Visual heatmaps to track your real consistency, both for individual habits and across your entire activity.

  • 📝 Rich Notes: A powerful editor that lets you link your notes directly to your projects (as tasks) and ideas.

A note on language: The platform is currently in Spanish, but it is very intuitive and works perfectly with browser auto-translate (Chrome/Edge). I’m already working on the native English version, but you can jump in and use all features today!

I’m not looking for partners—I just want people to try it out, break it, and tell me what they think. If you’re looking for a new way to organize your dev projects, I’d love for you to give it a spin.

Thanks for the support! 🚀

    I'm here to answer any technical questions about the stack (Next.js/NestJS/Supabase) or the roadmap!

About

I built Nexiun because I was tired of "context switching" constantly. I had to jump between Notion for notes, Jira for tasks, LucidChart for database diagrams, and another app for habits. My productivity was fragmented.
