The Blueprint Standard

arch0 is not a chatbot. Every project produces the same set of schema-validated, deterministic artifacts — the same deliverables a good agency creates before writing any code.

Fixed artifact set

Every project produces the same deliverables. No randomness, no missing sections. Same inputs, same outputs.

1Architecture Diagrams

How your system is structured — containers, relationships, and data flow

2Sequence Diagrams

Step-by-step interaction flows for every core feature

3API Contracts

Full endpoint definitions with request/response schemas

4Data Model

Database schema and entity relationships

5Repo Scaffolds

Ready-to-run frontend and backend project stubs

6Infrastructure + CI/CD

Cloud setup, pipelines, and container configs

7Product Backlog

Epics and user stories you can import into your tracker

8Decision Records

What was chosen, what was rejected, and why

9Deployment Guide

Step-by-step infrastructure setup instructions

10Cost Estimate

Monthly infrastructure and third-party cost projection

Validated, not vibes

Every artifact passes through a validation pipeline before it reaches you. Incompatibilities, missing fields, and architectural risks are caught automatically — not left for your developer to discover.

Schema enforcement

Every artifact conforms to a strict schema. Invalid outputs are rejected and regenerated — you never see incomplete or malformed deliverables.

Compatibility checks

Technology choices are validated against each other. If your stack has a mismatch (wrong ORM for your database, wrong IaC for your cloud), it gets caught before generation.

Risk analysis

Warnings surface when your architecture is too complex for your team size, your timeline is aggressive for the scope, or your budget doesn't match your infrastructure choices.

Start from a template

Pick a starting point that matches your product type. Each template comes with battle-tested defaults you can customize.

Simple SaaS

Single database, billing, basic auth — the fastest path to a subscription product

AI Product

LLM integration, vector storage, async workers, usage-based metering

Marketplace

Multi-tenant, payment splits, search, buyer-seller messaging

Internal Tool

Admin dashboard, role-based access, audit logs, SSO

Iterate without starting over

Change your requirements and only the affected artifacts regenerate. You can see exactly what changed between versions — architecture evolves like code.

v1 → v2 changes:

  Cost estimate
-   Fargate (1 service)        $146/mo
+   Fargate (3 services)       $438/mo

Export everything

Download a structured zip with all your artifacts — markdown docs, diagrams, API specs, database schemas, project scaffolds, infrastructure configs, and deployment guides. Hand it to a developer, an agency, or an AI coding tool.

Built for AI coding tools

The export includes context bundles designed for Cursor, Claude, and Copilot. Drop your blueprint into any AI coding tool and start building with full architecture context — no copy-pasting specs into chat windows.

Deterministic, not probabilistic

Same inputs, same outputs — every time. Your blueprint is generated from a structured spec, not a chat conversation. The output is reproducible, diffable, and version-controlled.
