StackPatch is a CLI tool that helps you quickly add production-ready features to your Next.js applications. No more copy-pasting boilerplate code or configuring complex setups—just run a command and you're done.

Think of StackPatch as shadcn/ui, but for complete features instead of components. Each patch is self-contained, fully reversible, and designed to work with your existing project structure. Whether you need authentication, payment integration, or other complex features, StackPatch lets you focus on building your actual application instead of reinventing the wheel.

Why StackPatch

Adding features to existing Next.js projects is a half-solved problem. Most tools force you into a new project structure or require extensive manual configuration. Other solutions often mean:

• Copy-pasting boilerplate code from multiple sources

• Manually configuring complex setups (OAuth, databases, middleware)

• Worrying about breaking existing code

• Struggling with path aliases and directory structures

• No way to safely revert if something goes wrong

Rather than just pushing third-party services or complex scaffolding tools as the solution, we believe we can do better as a community—hence, StackPatch.

StackPatch solves this by:

• ✅ Zero Configuration - Interactive setup guides you through everything

• ✅ Smart Detection - Automatically adapts to your project structure (app/ vs src/app/)

• ✅ Fully Reversible - Track and revert any installation safely with npx stackpatch revert

• ✅ Own Your Code - Every line of code is yours to modify and customize

• ✅ Production-Ready - Battle-tested patterns powered by Better Auth, not toy examples

• ✅ Incremental Adoption - Add features to existing projects seamlessly
