Next SaaS
The broad app foundation: database, billing, accounts, docs, ops, and growth.
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.
developer-platform
Developer Platform
API keys, public API surfaces, webhook delivery, usage, and developer docs.
b2b-saas
B2B SaaS
Team workspaces, invites, tenant context, permission models, and audit trails.
ai-saas
AI SaaS
Optional AI product modules for chat, routing, prompts, quotas, and metering.
vercel-native
Vercel Native
Deployment and managed storage adapters for teams building on Vercel.
cloudflare-native
Cloudflare Native
Worker-first deployment, storage, queues, durable objects, and edge primitives.
provider-adapters
Adapter Examples
Provider adapter examples that show integration shape without locking in the base.
saas-coverage
SaaS Coverage
A larger map of launch, security, billing, support, analytics, and ops modules.
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
Foundation
Small base building blocks for layout, settings, UX states, and app shell polish.
database
Database
Schema slices, migrations guidance, tenant-safe data patterns, and local backing stores.
auth-and-tenancy
Auth and Tenancy
Account flows, workspaces, tenant context, invitations, roles, and enterprise access.
billing
Billing
Subscriptions, entitlements, one-time purchases, credits, invoices, dunning, and taxes.
api-product
API Product
Developer-facing controls for keys, rate limits, public APIs, webhooks, and docs.
operations
Operations
Auditability, status, health, incident response, background jobs, and support workflows.
analytics-and-growth
Analytics and Growth
Product analytics, onboarding, lifecycle email, activation, retention, and feedback loops.
providers
Providers
Adapter modules for hosted services, kept optional so the base scaffold stays small.
optional-ai
Optional AI
AI modules are available when useful, but they are not required for the registry model.
docs-and-deployment
Docs and Deployment
Product docs, provider deploy paths, containers, and production-readiness notes.
Provider Options
Choose the provider after you choose the capability.
Provider cards show selectable adapter paths. Favicon marks are compact identifiers; the module contract still stays source-first and editable.
