App Builder
Software development skill, available on Zeplik
App Builder is a ready-to-run software development skill on Zeplik. Not for turning an idea into a written spec (use idea-to-spec). Ask in plain language and Zeplik applies the skill's method for you inside the conversation, on whichever AI model you prefer. It returns a structured code you can keep and reuse: Scaffolding plan plus language-tagged code blocks per file -- each titled with its filename, complete and runnable (see artifact-templates/code.md).
The App Builder skill loads automatically when your request matches it, or you can invoke it directly by typing /app-builder in any chat. It works with attachments, connectors, and any model that supports the task, so you get the same expert method every time without setting anything up.
What the App Builder skill can do
- Detect project type and pick a matching tech stack
- Plan database schema, API surface, pages, and components
- Sequence the build as schema, backend, frontend, then deployment
- Deliver code pass by pass with progress summaries and next steps

How the App Builder skill works
/app-builder
Application building orchestrator. Analyzes the user's request, determines the project type and tech stack, plans the structure, and coordinates the build from natural language to working application.
Process
- Detect the project type from the request (web app, SaaS, landing page, API, mobile, desktop, extension, CLI, monorepo).
- Select the tech stack using the defaults below, adjusting for stated constraints (team skills, hosting, budget).
- Plan the structure: database schema, API surface, pages, and components.
- Sequence the build: schema first, then API/business logic, then UI, then deployment.
- Report progress at each phase and confirm direction before large steps.
Ask the user for anything you need (existing code, brand assets, API keys they plan to use) -- have them paste or upload it rather than assuming access.
Project Type to Stack Mapping
Quick-start defaults for new projects. Pick the row that matches the request.
| Project Type | Tech Stack | When to Use |
|---|---|---|
| Full-stack web app | Next.js + Prisma | General web app with data and auth |
| SaaS product | Next.js + Stripe | Subscriptions, billing, gated features |
| Landing page | Next.js static + animation library | Marketing/launch page |
| Vue full-stack app | Nuxt 3 + Pinia | Teams preferring Vue |
| REST API | Express + JWT | Standalone Node API |
| Python API | FastAPI | Python teams, ML-adjacent backends |
| Mobile app | Expo (React Native) + Zustand | Cross-platform mobile |
| Cross-platform mobile | Flutter + Riverpod | Dart/Flutter teams |
| Desktop app | Electron + React | Installable desktop tool |
| Browser extension | Chrome Manifest V3 | In-browser tooling |
| CLI tool | Node.js + Commander | Command-line product |
| Monorepo | Turborepo + pnpm | Multiple apps/packages together |
Build Coordination
Treat the build as a pipeline of specialist passes, executed in order:
| Pass | Role |
|---|---|
| Planning | Task breakdown, dependency graph |
| Database | Schema, migrations, seed data |
| Backend | API routes, business logic, auth |
| Frontend | UI components, pages, state |
| Deployment | Hosting setup, environment config, preview |
Rules:
- Do not start a pass until its dependencies are done (no UI against an undefined schema).
- Keep each pass small enough to review; deliver code in chat as complete files the user can drop into their project.
- After each pass, summarize what was produced and what comes next.
Adding Features to an Existing Project
When the request extends an existing app rather than starting fresh:
- Ask the user to paste the relevant files (schema, routes, components) or describe the current structure.
- Analyze the feature request: which layers does it touch (data, API, UI)?
- Plan the minimal change set and confirm it.
- Deliver changes layer by layer with clear placement instructions.
- Include error handling and edge cases in each delivered file.
Worked Example
User: "Make an Instagram clone with photo sharing and likes"
App Builder process:
- Project type: Social Media App
- Tech stack: Next.js + Prisma + Cloudinary (media) + Clerk (auth)
- Create plan:
- Database schema (users, posts, likes, follows)
- API routes (about 12 endpoints)
- Pages (feed, profile, upload)
- Components (PostCard, Feed, LikeButton)
- Execute passes in order (schema, API, UI, deploy)
- Report progress after each pass
- Hand off run/preview instructions
