Scaffolding

One command. A production-grade agentic app — backend, frontend, infra, CI, planning skeleton — all pre-wired and ready to push.

The problem

Building production-grade agentic apps from scratch wastes months.

Building a production-grade agentic app from scratch is a six-month engineering project: FastAPI plumbing, LangGraph workflows, Next.js conversation UI, Helm charts, ArgoCD pipelines, Clerk auth wiring, observability instrumentation, Cerebe SDK integration — all before you write the first agentic feature.

Most teams ship something that works in dev and crumbles the first time it sees real traffic. The teams that ship something good spent more time on plumbing than on the agentic feature itself.

How it works

sage init scaffolds the whole stack — and you own every line.

sage init my-product asks four questions — product domain, personas, Cerebe instance, Dark Factory on/off — then generates a complete project ready to make dev and start building.

The output is plain code in standard frameworks: FastAPI for backend, Next.js 14 for frontend, Helm + ArgoCD for deployment. You modify anything, eject anything, deploy anywhere. No runtime lock-in.

FastAPI + LangGraph backend with ReAct loops and specialist delegation patterns
Next.js 14 frontend with conversation history, contextual AI, polished UI
Helm chart + ArgoCD application + multi-environment values files
Multi-agent CI workflows + local critic config + cycle-doc planning skeleton
Cerebe SDK + Dark Factory hooks installed and verified on first commit
All output is standard FastAPI + Next.js + Helm — no proprietary runtime, fully ejectable

Pricing relevance

Sage Blueprint is free to use — the scaffold + Cerebe SDK + Dark Factory hooks ship in every paid Team / Business / Enterprise tier. Free OSS tier scaffolds public repos for evaluation.

Open-source posture

Scaffolding templates ship in OSS (the Copier template is public). The opinionated wiring, multi-agent CI workflows, and Cerebe + Dark Factory integration are the curated IP that lives behind a hosted plane.

Get Started

Skip the six-month plumbing project.

sage init generates a deployable agentic product — backend, frontend, infra, CI, all wired to Cerebe and gated by Dark Factory. Reach out for early access.
