Networking

TCP/IP, DNS, HTTP and more — full internet connectivity on hardware that was never meant to have it.

Cryptography

Modern primitives and protocols — AES, TLS 1.3, ECDHE, SHA-256 — built for resource-constrained devices.

Hosting & Backends

Game servers, mirrors, and custom APIs purpose-built for calculator software ecosystems.

Open Source

Transparent, reproducible, and community-driven. Every line is public from day one.
