Draw your architecture.
Generate the code.
Node-based development for distributed systems. Design services, databases, message queues, and their connections—then generate the foundational implementation. No vendor lock-in. Standard code you own completely.
No credit card • Bring your own API keys • Generated code is yours forever
Visual architecture platform that generates production-ready code
If you can draw an architecture diagram, you can use Tattami. Design system-level changes and generate the foundational code.
Component Library
Pre-built, production-ready components: services, databases, message queues, and infrastructure. Configure technology stack, descriptions, and deployment settings for each node.
Connection Designer
Visual connection system with full control over protocols (REST, gRPC, WebSocket), authentication methods (JWT, OAuth2, API Key), and data formats.
Hybrid Generation
Deterministic outputs for standards (Proto files, OpenAPI specs, database schemas). Context-aware LLM scaffolding with exact tech stack and architectural requirements.
No Lock-In Architecture
Generated code uses standard frameworks and libraries. No Tattami runtime dependencies. No proprietary APIs. Stop using Tattami anytime—keep building manually.
Built-in Validation
Checks architecture before generation: missing connections, circular dependencies, authentication gaps, and protocol mismatches.
Architecture-Level Focus
Generates foundations, not features: service structure, database models, inter-service communication, auth setup. You implement the business logic.
How It Works
From architecture diagram to production-ready code in four steps
Design on Canvas
Drag components from the library. Configure each node with name, description, technology stack (Go + Gin, TypeScript + Next.js, Python + FastAPI), and service-specific settings.
Frontend webapp using TypeScript that handles user authentication and real-time updates
Connect Components
Draw connections between nodes. Configure each connection with communication protocol (REST, gRPC, WebSocket), authentication method, data format, and flow direction.
WebApp → API Gateway via WebSocket with API Key authentication
Generate Implementation
Hit "Build" and get deterministic outputs (Proto files, OpenAPI specs, schemas), context-aware code (service scaffolds), infrastructure as code (Docker, K8s), and connection implementations.
Complete service structure with routing, authentication middleware, and database clients
Deploy or Customize
Export to your repository. All code is standard, framework-based, with no Tattami dependencies. Modify freely, add business logic, deploy anywhere. Return when architecture evolves.
Update the diagram, regenerate affected files, preserve custom logic
Real Architecture Example
Real-time analytics pipeline in 2 hours vs. 3-4 days manual
Architecture Diagram
Generated in 2 hours
- React app with WebSocket client
- Go API Gateway with Gin framework
- WebSocket server implementation
- Kafka producer and consumer setup
- Go stream processor with Kafka consumer
- Data processing scaffold
- PostgreSQL schema and migrations
- Docker Compose orchestration
- All authentication middleware
You add:
Frontend UI components, specific event processing logic, analytics algorithms, business rules
The Right Tool for the Right Job
Tattami's value scales with architectural complexity
Perfect For
- New greenfield projects - Eliminate blank-slate setup phase
- Cross-service features - Changes touching 2+ services
- Adding infrastructure - New event pipeline, caching layer, new microservice
- Service extraction - Breaking functionality out of monoliths
- Architecture refactoring - Changing service boundaries or communication patterns
Use Your IDE For
- Single-service changes
- Individual endpoint modifications
- Bug fixes
- Frontend components
- Business logic implementation
Rule of thumb: If you'd sketch a diagram to plan it, use Tattami.
Time Savings
| Scenario | Time (Manual) | Time (Tattami) | Advantage |
|---|---|---|---|
| 2-service feature | 2 days | 2 hours | 10x faster |
| New event pipeline (3 services) | 1 week | 3 hours | 18x faster |
| Greenfield microservices (5 services) | 2-3 weeks | 1 day | 15x faster |
