Insights

Key Learnings

What I discovered while building this

Durable Objects make consistent counting at the edge surprisingly clean

Latency budgets shrink fast - every microsecond matters in the hot path

Falling open on Durable Object errors is safer than failing closed for most APIs

Note: This is an experimental project in the beta stage. It represents a learning exercise and technical exploration rather than a production-ready solution. Code and patterns may change significantly.
