Shared key-value store and feature flags

The Coffer

The Coffer holds short key-and-value pairs — feature flags, settings, counters, session fragments — in memory so reads and writes come back in milliseconds. It answers over a REST API and is also bound into Edge Functions, which means your app and your edge code always read the same values with no extra plumbing. Feature flags are built in: turn a feature on for everyone, for a fixed share of visitors, or for one workspace, and change it without a deploy. Values are scoped to your workspace and namespace, so one tenant never reads another’s keys. This is a small, fast coordination store for flags and hot counters — not a replacement for The Cellar when you need queries, relations, or durable documents.

In plain English — A fast shared cupboard for small pieces of data — settings, flags, and counters — that your app and your edge code can both read and write in milliseconds.
