Architecture & technical design

How PlanMySaaS designs your system architecture, database schema, API routes, and technical implementation strategy.

Architecture page

The Architecture section generates a complete system design for your product. This is where the AI translates your product idea into an implementable technical blueprint.

What gets generated

System Overview
High-level architecture description — monolith vs microservices, client-server separation, deployment strategy.
Component Diagram
Visual representation of your system's major components and how they communicate (Frontend, API Layer, Database, External Services, Background Jobs).
Database Schema
Entity relationship design with tables, fields, data types, relationships (one-to-many, many-to-many), and indexes.
API Design
RESTful or GraphQL endpoint structures with authentication, authorization, pagination, and error handling patterns.
Tech Stack
Recommended frontend framework, backend language, database, hosting, CI/CD, and third-party services — with reasoning for each choice.
Scalability Notes
How the architecture handles growth — caching strategy, CDN usage, horizontal scaling, rate limiting, and database optimization.

Technical Design page

The Technical Design section goes deeper than Architecture, focusing on implementation-level decisions:

  • Authentication flow — OAuth, JWT, session management, role-based access control
  • State management patterns — server state, client state, cache invalidation
  • Error handling strategy — error boundaries, retry logic, user-facing error messages
  • API schema details — request/response shapes, validation rules, pagination patterns
  • Background job architecture — queue systems, cron jobs, webhook handlers
  • Security considerations — input sanitization, CSRF protection, rate limiting, encryption
  • Deployment architecture — staging vs production, environment variables, CI/CD pipeline
💡

Technical Design is especially valuable for non-technical founders. Share this document with your development team or freelancer — it gives them a clear implementation roadmap with specific technical decisions already made.

Frontend Blueprint page

The Frontend Blueprint section focuses specifically on the client-side architecture:

  • Page structure and routing — what pages exist, how they connect, navigation flows
  • Component hierarchy — which components are shared, which are page-specific
  • UI/UX patterns — form patterns, loading states, error states, empty states
  • Responsive design strategy — breakpoints, mobile-first considerations
  • Design system tokens — color palette, typography scale, spacing system

This output is particularly useful when combined with the Prompt Studio — the frontend-specific prompts reference this blueprint directly, so your AI coding tool generates UI code that matches the planned design system.

How architecture quality varies

The quality of the generated architecture depends heavily on your wizard input:

Basic input
'A task management app' → Generic CRUD architecture with basic auth and a simple database.
Good input
'A task management app for remote teams with real-time collaboration, Slack integration, and time tracking' → Event-driven architecture with WebSocket support, third-party API integration layer, and time-series data handling.
Excellent input
'A task management app for remote construction teams in India. Must work offline in rural areas, sync via WhatsApp, support Hindi/English, and integrate with government compliance systems' → Offline-first architecture with sync engine, multi-language support, WhatsApp Business API integration, and government API adapter patterns.
