Ship faster with higher quality. Lean specs that both humans and AI understand.
LeanSpec brings agile principles to SDD (Spec-Driven Development)—small, focused documents (<2,000 tokens) that keep you and your AI aligned.
# Try with a tutorial project
npx lean-spec init --example dark-theme
cd dark-theme && npm install && npm start
# Or add to your existing project
npm install -g lean-spec && lean-spec initVisualize your project:
lean-spec board # Kanban view
lean-spec stats # Project metrics
lean-spec ui # Web UI at localhost:3000Next: Your First Spec with AI (10 min tutorial)
High velocity + High quality. Other SDD frameworks add process overhead (multi-step workflows, rigid templates). Vibe coding is fast but chaotic (no shared understanding). LeanSpec hits the sweet spot:
- Fast iteration - Living documents that grow with your code
- AI performance - Small specs = better AI output (context rot is real)
- Always current - Lightweight enough that you actually update them
