New Ruby web application framework being designed and prototyped by Stephen Margheim and Joel Drapper over roughly three years. Also spelled Yippi/Yippy in spoken transcript. As of March 2025 it is 'vaporware' — private repo, half-working experiments, many working code experiments across Joel's and Stephen's machines but no public release. Defining constraints set on day one and non-negotiable: (1) SQLite-only for all persistent data (primary, cache, jobs, pub/sub, full-text search — many SQLite databases, only SQLite databases); (2) single-machine deployments with a persistent file system. Core design elements: repository-pattern-inspired model layer with named roles (resource / model / table / data source) and first-class query building (plus a pure-Ruby-hash AST representation of SQL that adds composability on top of SQL); routing-tree controllers with zero boot-time route parsing, built for single-digit-millisecond boot regardless of app size; view layer fully built on Phlex (views, components, kits) and Literal::Properties, exploiting selective rendering to noop unused method calls; quickdraw-powered testing targeting 10,000 tests in under a second via core saturation, per-thread in-memory SQLite DBs cloned from a single-fixture template, and test-mode shortcuts like Phlex producing a queryable AST instead of HTML; deployment managed by the framework itself, spinning up Digital Ocean or Hetzner VMs from an API key and orchestrating isolated app/infrastructure/schema deployment types through a built-in deployment queue (sub-second deploys; Docker for infrastructure, no Docker for app deploys); batteries-included exception monitoring (incl. CSP violations), performance monitoring, job monitoring, logs, and database inspection. Guided by an 'aggressive love of simplicity' and an 'accordion of complexity' that lets each part of an app collapse to one file or expand to many well-named layered files as needed. Wild vaporware ideas still on the table include a Bootsnap-replacement that writes Ruby VM instructions into one SQLite file used as the deployment artifact, purely declarative migrations, and CI+deploy completing in under a second from a laptop.
