Fern Labour

https://fernlabour.com

FernLabour.com is a SaaS tool for labour tracking and real-time sharing. It combines a contraction timer with a private subscription system that lets loved ones follow along via SMS, WhatsApp, or email. The backend is an event-sourced system on Cloudflare Workers and Durable Objects, with one Durable Object per labour.

Event sourcing on Cloudflare Workers and Durable Objects

#cloudflare #architecture #Rust
