A tiny, readable DSL is the whole artifact. No schema files, no database to connect to.

Watch it project
Every write updates the base table and each secondary index live, with a diff of what moved.
See the cost
Each write shows its estimated capacity, so a reindex visibly costs more than a plain update.
Check your access patterns
Declare what your design must serve, and Keyway runs each query to grade what is covered.
Learn by watching
Guided, narrated tours step through real models, from the editor basics to conditional writes.
Private by default
Everything runs client-side. Your model never leaves the browser tab.
