Stryama

AI-Powered No-Code Development Platform

Stryama democratizes software development by enabling anyone to build functional, production-ready applications through natural language prompts. It combines advanced AI code generation with a secure, sandboxed live preview environment, allowing users to create, visualize, and refine full-stack web applications in real-time.

🚀 Key Features

• 💬 Conversational Development: Build apps by describing them in plain English. No coding knowledge required.
• 🤖 Intelligent Code Generation: Powered by Anthropic Claude Code SDK to generate high-quality, modern React/Next.js code.
• 👁️ Live Sandboxed Preview: Instant, secure application previews running in isolated E2B environments.
• 🔄 Iterative Refinement: Refine and modify your application through continuous conversation.
• 🛠️ Modern Tech Stack: Generates production-ready code using Next.js 15+, React 19, Tailwind CSS, and ShadCN/UI.
• 🔐 Enterprise-Grade Security: Integrated Clerk authentication and secure runtime execution.
• 🗄️ Full Persistence: Robust data management with PostgreSQL and Prisma ORM.

🏗️ Architecture

Stryama is built on a serverless-first, TypeScript monorepo architecture leveraging the T3 Stack foundation.

• Frontend: Next.js 15+ (App Router), React 19, Tailwind CSS v4, ShadCN/UI
• Backend: tRPC (Type-safe API), Next.js Serverless Functions
• Database: PostgreSQL (via Neon/Supabase), Prisma ORM
• AI Engine: Anthropic Claude Code SDK
• Execution Engine: E2B Sandboxed Environments
• Auth: Clerk

For a deep dive into the system design, please refer to the Architecture Documentation.

🧪 Testing

Stryama uses Vitest for unit testing with a focus on critical business logic and services.

Test Coverage Strategy

Phase 1 (Current): Critical Services Layer ✅

• ✅ Usage Tracking & Billing Logic (prevents cost overruns)
• ✅ Rate Limiting (prevents API abuse)
• ✅ Model Selection (ensures cost optimization)
• ✅ File Persistence (prevents data loss)
• 95 tests with 100% coverage on critical services

Phase 2 (Planned): API Layer & Integration Tests

• tRPC routers (AI, Project, Subscription, Usage)
• Sandbox Manager & Stream Manager
• Target: 20-30% overall coverage

Running Tests

# Run all tests in watch mode
pnpm test

# Run tests with UI
pnpm test:ui

# Run tests with coverage report
pnpm test:coverage

# Run tests once (CI mode)
pnpm test:ci

# Run tests for changed files only
pnpm test:changed

CI/CD

Tests run automatically on:

• Every commit via pre-commit hooks (changed files only)
• Every pull request via GitHub Actions
• Every push to main branch

See .github/workflows/test.yml for CI configuration.

Coverage Reports

Coverage reports are generated in the coverage/ directory:

• coverage/index.html - Interactive HTML report
• coverage/lcov.info - LCOV format for CI integration

Current thresholds:

• Lines: 3%
• Functions: 4%
• Branches: 3%
• Statements: 3%

Note: Low overall percentage is intentional - we focus on 100% coverage of high-risk business logic rather than 100% coverage of all code. UI components and integration code will be tested via E2E tests.

📦 Deployment

Stryama is optimized for deployment on Vercel.

• Build command: pnpm build
• Output directory: .next
