WHY SUPER DURABLE EXISTS

Reliable systems can be simpler than the problems they solve.

We believe software engineers should be able to express long-running intent directly, persist it structurally, and trust the platform to carry it through failure.

SIMPLE

Remove concepts before adding abstractions.

RELIABLE

Design recovery into the normal path.

STRUCTURAL

Persist data and actions as one coherent system.
