Prices, orders, risk checks, and dashboards can move fast without splitting into separate systems.
Now you’re six months in. Each new feature depends on five others. One edit turns into ten. Every change gets slower, pricier, riskier, and more stressful than it should.
Products that want to get huge cannot afford this.
How does it work? Instead of depending on each other, every feature drops an envelope with info into one place.
Bitfield stores every envelope. When another feature needs that envelope’s info, it can pick it up now, in a year, offline, after a crash, or on another device.
Usually, having features talk through the shared place is slower to build and slows your product down compared to talking to each other directly.
we made that shared place faster than talking directly.
Bitfield lets features write product data faster and read product data faster than the fastest database in the world.
Now you get the structure and still get the speed. Your AI gets product data almost instantly, so it can keep reading, checking, and building instead of waiting on the database.
And the source of truth is persistent storage, not an in-memory-only trick. You can still use PlanetScale, Postgres, Redis, TigerBeetle, SpacetimeDB, or anything else as a slot when it is the right tool.
An active device is a device, server, or runtime identity that asks Bitfield to run during the billing window. Dormant installs, static visitors, seats, projects, AI tokens, and revenue do not count by themselves.

Each per-device rate applies only inside its range, then the ranges add up.
One device is enough to begin.
This is the same runtime that can follow the product anywhere.
