Map the architecture
Describe the services, boundaries, and relationships that make up your system.
The system design workbench
Design your system.
Connect every detail.
Architecture, data, flows, requirements, and APIs. One connected blueprint for the team bringing your system to life.
Built for architects, engineering leads, and the teams they build with.

Follow the connections.
Every view describes the same project. Move from a service to its data, behavior, requirements, and contract without losing the bigger picture.

Design tables and relationships, associate schemas with architecture elements, and export your database design as DDL.
Place an order
REQUEST FLOW- Submit orderWeb application → Order service
- Validate the requestOrder service checks the submitted order
- Persist and respondOrder service → Orders database → Web application
Describe request flows as ordered steps between the elements in your architecture.
Make expectations explicit
FUNCTIONAL & NON-FUNCTIONALFR-1
Create an order
A customer can submit an order and receive its identifier.
NFR-2
Protect order data
Customers can access only their own orders.
Keep functional and non-functional requirements linked to the architecture elements they describe.

02 / From intent to implementation
Give every decision
a place in the blueprint.
Define the details
Connect database schemas, request flows, requirements, and API contracts to those elements.
Carry the context forward
Keep notes and project documentation alongside the design. Export contracts and schemas, and access the model through MCP.
03 / Built to work with your tools
Give your AI tools
the project context.
Expose your project's architecture, data model, flows, requirements, and contracts through the Model Context Protocol.
The existing MCP server runs locally against your project data. Configure it in a compatible client to read or update the connected model.

A few details
Before you
open the app.
What is Build2Prod?
A system design workbench for the work that happens before implementation: architecture, database schemas, request flows, requirements, API contracts, and supporting documentation.
Who is it for?
Software architects, engineering leads, and teams that need a shared, connected description of the system they are building.
Can I export my designs?
You can export database schemas as DDL and API contracts as OpenAPI specifications. The app also supports project snapshots.
How does MCP work?
The MCP server runs locally and connects to project data. A compatible client can use its tools and resources to work with the model. Setup is required; opening the website does not automatically connect an AI client.
Where do I get started?
Choose Open app to reach the existing sign-in screen at app.build2prod.com. Account creation is available there when registration is enabled.
