Daily analysis of 70 major global ports using free Sentinel-2 satellite imagery and Gemini Flash. SupplyWatch detects operational disruptions — congestion, weather events, labour actions, geopolitical risks — before they show up in shipment tracking.
Built for mid-market manufacturers and logistics operators who can't afford USD 100k+ supply chain visibility platforms. The entire system runs on under AUD $30/month at demo scale.
Satellite imagery of Beira on 15 March 2026 showed what appeared to be normal berth activity — vessels alongside, yard stacked as expected, cranes operating. But external data told a different story: tropical storm conditions in the Mozambique Channel, 12.5 days average vessel waiting time, limited sheltered berthing at this exposed port.
SupplyWatch weighs satellite imagery against external context — weather, labour actions, geopolitical signals — and applies explicit precedence rules. When external indicators show severe disruption, the system overrides ambiguous imagery. The Beira analysis correctly flagged 5/5 severity despite the satellite image looking unremarkable. A single-modal AI, looking only at pixels, would have called it normal.
Two-stage Gemini analysis: an observation stage describes what the imagery shows, then an assessment stage weighs that against external context. This is not a one-shot prompt — the model reasons across evidence sources.
Weather data (Open-Meteo), labour events, peak season calendars, and geopolitical signals from 18 tracked events are injected into every analysis. When external context conflicts with imagery, the system has explicit rules about which evidence takes precedence.
Every briefing carries a High/Medium/Low confidence grade. Satellite imagery is cached in GCS for human review. Briefings include container yard fill percentages, vessel counts at berth and anchorage — verifiable metrics, not narrative guesswork.
Sentinel-2 L2A imagery from the Copernicus programme is free. Gemini Flash costs a fraction of Pro. Cloud Run scales to zero between daily runs. The entire system runs on under AUD $30/month at demo scale. A production deployment with 200+ ports would stay under AUD $200/month.
