Sionna Visualizer — first public visual dashboard built on NVIDIA Sionna for 6G research

Hi NVIDIA Sionna community,

I’m Vinayak, a Java Backend Developer from
Pune, India and a member of the NVIDIA AI
Aerial / 6G Developer Program.

I just shipped Sionna Visualizer the first
publicly deployed visual dashboard built on
top of NVIDIA Sionna.

━━━━━━━━━━━━━━━━━━━━━━

What it does:

→ Run 6G OFDM simulations in your browser
→ See BER vs SNR curves rendered instantly
→ Full simulation history backed by PostgreSQL
→ Share any result with one public link
→ JWT authenticated and cloud deployed

━━━━━━━━━━━━━━━━━━━━━━

Tech stack:

→ Java Spring Boot 3 — REST API backend
→ Python FastAPI — Sionna simulation bridge
→ Angular 17 — interactive dashboard
→ PostgreSQL — simulation history storage
→ Docker — single command local setup
→ Railway + Vercel — cloud deployment

━━━━━━━━━━━━━━━━━━━━━━

Current state:

Phase 1 is complete and live. The simulation
currently uses realistic mock data. Real GPU
Sionna integration is Phase 2 — which I am
now planning.

━━━━━━━━━━━━━━━━━━━━━━

Why I built this:

200,000+ researchers download Sionna. Every
single one gets raw Python output — numbers,
tensors, Jupyter notebooks. No visual layer
existed publicly. I built that missing layer.

━━━━━━━━━━━━━━━━━━━━━━

Questions for the community:

  1. What visualizations beyond BER vs SNR would
    be most useful for your research?

  2. Which Sionna simulation types should I
    prioritize for real GPU integration in Phase 2?

  3. Any feedback on the architecture or approach?

Would love input from researchers who use
Sionna daily. This tool is built for you.

Update GitHub now has complete README
with all features, live URLs, and
docker-compose setup.

Also added v1.0.0 and v2.0.0 releases
with full changelog.

Thanks Vinayak for your contribution. Do keep the innovations coming.
