strata dev runs your whole app on your machine — the database, the storage, the jobs and the app itself — with no cloud account.
npx strata devWhat it starts
Postgres on a free port, with your migrations applied
A storage emulator compatible with the S3 API
Your app, with hot reload
Studio, a data browser, at
localhost:5555
Seed data
await db.user.createMany({ data: [{ email: "a@example.com" }, { email: "b@example.com" }] });npx strata db seedstrata dev --fresh drops the local database and re-runs every migration and the seed. It never touches a remote database, whatever DATABASE_URL says.
