The software factory
for agents and humans
Purpose-built for spec-driven development. Designed for consistency. SFab sets a new standard for planning and building products with AI.
A new species of development tool.
Template-locked execution with automated quality gates ensures that your agents write production-grade code every time.
Spec-Driven
Every feature starts with a living SPEC.md. Agents implement against acceptance criteria, ensuring no unapproved scope creep.
Template-Locked
A battle-tested TS + Cloudflare + TanStack template. Agents work within rigid guardrails to eliminate tech-stack chaos.
Human Orchestrated
You stop reviewing syntax. Humans approve the feature's function and intent while specialized agents handle the fabrication.
Protocol Steps
The predictable path from idea to production.
Spec Agent
Builds living SPEC with rigorous conformance tests.
Architect Agent
Creates architecture documents and project issues.
Coder Agent
Implements features in guarded branches.
Reviewer Agents
Enforces QA, security, and quality gates.
