Sunona AI

Inspiration

Sunona AI was inspired by the vision of building an open‑source voice intelligence platform that blends backend stability with real‑world usability.
Our goal: democratize advanced voice AI without commercial SaaS barriers.

What We Learned

  • Scalable backend design with PostgreSQL, Redis, Docker
  • Reviewer‑friendly ASCII diagrams + clear documentation
  • Licensing as protection against misuse

How We Built It

  • Backend: Python + FastAPI (Dockerized)
  • Database: PostgreSQL (Neon/Supabase free tiers)
  • Cache: Redis for low‑latency responses
  • Deployment: Railway/Render free tiers + Cloudflare SSL

Challenges

  • Budget limits for production hosting
  • Worker crashes (Uvicorn restarts, Redis startup)
  • Strict page limits → concise ASCII diagrams

Example Math (LaTeX)

Inline (Latency):

[ L = \frac{t_1 + t_2 + t_3 + \dots + t_n}{n} ]

Display (Throughput):

[ T = \frac{R}{C \cdot U} ]

Where:

  • (T) = throughput (req/s)
  • (R) = total requests
  • (C) = CPU cores
  • (U) = utilization factor

Final Notes

We believe Sunona can become a global benchmark for open‑source voice AI, empowering developers, educators, and communities worldwide.
