Deterministic scaffolding + governance
They give you a prototype.
We give you a governed codebase.
Stackbilder generates production-ready projects with security threat analysis, architectural decision records, and test plans — automatically. In ~20ms. No LLM required.
What ships with your code
Every scaffold includes governance. Automatically.

Security threat analysis
STRIDE-based threat modeling for your specific architecture. Identifies injection vectors, auth weaknesses, and data exposure risks before you write a line of code.
Architectural decision records
Every non-obvious choice documented with context, alternatives considered, and consequences. Your future self (and your team) will thank you.
Test plans
Integration and unit test specifications derived from your architecture. Coverage targets, frameworks, and specific scenarios — ready to implement.
Architectural constraints
Machine-readable guardrails that prevent drift. When you use Phase 2 LLM polish, these constraints guide generation — the AI works within your architecture, not around it.
Two-phase architecture
Deterministic skeleton. Optional LLM polish.
TarotScript engine
~20ms. Zero inference cost. Your intention maps to a deterministic deck of architectural cards that produce project structure, config files, and the full .ai/ governance suite.
Cerebras fast inference
Takes the Phase 1 skeleton and generates idiomatic, production-grade code. The key difference: the LLM works within the governance constraints from Phase 1. Guided generation, not blind generation.
Why Stackbilder
The only empty quadrant on the map.
Deterministic generation + full governance output. Nobody else does both.
vs. AI builders
Bolt, Lovable, and v0 generate prototypes that break in production. No threat analysis. No ADRs. No test plans. Just code and hope.
"They give you a prototype. We give you architecture."
vs. Traditional scaffolders
Yeoman, Cookiecutter, and create-* CLIs generate file structure. Stackbilder generates file structure, governance, security analysis, and architectural documentation.
"Cookiecutter generates files. Stackbilder generates architecture."
vs. Backstage
Backstage needs a platform team to run — $22/dev/month managed, or 2-3 engineers to self-host. Stackbilder delivers the same governance output with zero operational overhead.
"Backstage needs a platform team. Stackbilder IS the platform team."
