DevStack Planner is an offline software architecture planner and stack estimation tool designed to help developers, product managers, and architects structure their technical projects. Plan your application's architecture, choose software stacks, estimate code complexity, and track milestones entirely on your local device.

With DevStack Planner, you can map out frontend, backend, database, and hosting solutions for your projects and calculate a realistic complexity score based on your team size and application scale.

Core Features:

* Project Profile Builder: Create and manage software project profiles with titles and detailed descriptions.
* Multi-Platform Selection: Target multiple environments including Web, iOS, Android, Desktop, Cloud Agent, and Cross-Platform.
* Custom Tech Stack Configurator: Choose from a curated selection of development technologies:
- Frontend: React (TypeScript), Next.js, Vue.js (Nuxt), React Native (Expo), Flutter, SwiftUI, Kotlin Jetpack Compose, or Headless.
- Backend: Node.js (Express/NestJS), Python (FastAPI/Django), Go (Gin/Fiber), Rust (Actix/Axum), C# (.NET Core), Java (Spring Boot), Serverless, or No-Code.
- Database: PostgreSQL, MongoDB, SQLite, Redis, DynamoDB, MySQL/MariaDB, Supabase DB, or Firestore.
- Hosting: Vercel/Netlify, AWS, GCP, Vultr/DigitalOcean, Heroku/Render, Cloudflare, Docker VPS, or Expo EAS.
* Smart Complexity Estimator: Input your estimated screens count, APIs count, team size, and data synchronization needs to calculate a visual complexity score (0-100%) categorized from Simple to Enterprise.
* Milestone Checklist: Create, toggle, and manage milestones for each project with a visual progress bar.
* Architecture Journal: Write, edit, and save design notes and project ideas directly within the app.
* 100% Offline & Private: All data is saved on your device using MMKV local storage. Zero network permissions, zero tracking, and zero external APIs.
