Public source registry

Modules, presets, and provider adapters for SaaS apps.

StackFoundry lets teams install production SaaS modules as editable source code. Modules include source files, docs, env notes, tests or checklists, and maintenance guidance. Presets are curated bundles. Providers stay optional adapters.

Featured Paths

Start with a preset, then swap adapters as your stack settles.

Presets are install paths through the registry, not new frameworks. They collect the modules most teams need for a product shape while keeping provider choices explicit.

Module Families

The registry is organized around product capabilities.

Each card points at concrete modules you can inspect, install, and maintain as source. The base scaffold stays small; capabilities are added only when the app needs them.

Foundation

Small base building blocks for layout, settings, UX states, and app shell polish.

Database

Schema slices, migrations guidance, tenant-safe data patterns, and local backing stores.

Optional AI

AI modules are available when useful, but they are not required for the registry model.

Provider Options

Recognizable services, modeled as optional adapters.

Use the providers that match your stack. Favicon marks are shown only as compact identifiers for adapter cards; the modules still install as editable code.
