For developers
Build with SkyCache
SkyCache Nexus is intentionally modular. The core is a Python hub that ingests public content, prioritizes it, serves a mobile-first offline portal, and can form a multi-node community mesh fabric (DTN + opportunistic open gateway) — wrapping tools like SatDump and gr-satellites instead of reinventing demodulation. Not free commercial broadband.
Stack
- Python 3.11+ · FastAPI · SQLite · static PWA ·
skycache.nexus - SoapySDR / RTL-SDR for receive-only hardware access
- SatDump CLI for free-to-air weather decode
- gr-satellites for open amateur / CubeSat telemetry
- hostapd + dnsmasq + batman-adv templates for village fabric
- Apache-2.0 software tree

Plugin contract
Decoders implement a small protocol: name, legal_profile (fta_public | amateur_open | file_import_only), can_handle, run → CaptureResult. Commercial decrypt plugins are out of scope and will be rejected.
