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.
How your system is structured — containers, relationships, and data flow
Step-by-step interaction flows for every core feature
Full endpoint definitions with request/response schemas
Database schema and entity relationships
Ready-to-run frontend and backend project stubs
Cloud setup, pipelines, and container configs
Epics and user stories you can import into your tracker
What was chosen, what was rejected, and why
Step-by-step infrastructure setup instructions
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.
Single database, billing, basic auth — the fastest path to a subscription product
LLM integration, vector storage, async workers, usage-based metering
Multi-tenant, payment splits, search, buyer-seller messaging
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 Architecture diagrams ~ Modified: container diagram + Added: checkout flow sequence diagram
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.
