CLI Access (Beta)
Pull specs & run refinements straight from your terminal
Starter, Professional, and Ultra subscribers can download the Specdriver CLI, log in with the same Supabase auth tokens, and run the exact API calls the web app uses. Export markdown, trigger builder drafts, fetch node specs, and apply AI refinements without opening a browser.
- • Device auth + PAT-friendly login tied to your Supabase user.
- • Project/spec pulls in JSON, markdown, or folder formats (perfect for Claude/Cursor).
- • Node-level commands expose refine/apply flows you already trust in the UI.
- • Always keep permissions, credits, and logging centralized—just pass your Supabase cookies.
Starter >= CLI; Free tier stays browser-only.

Why SCAFFOLD
Prevent Hallucinations, Ship Precision
Stop fighting AI hallucinations. Start building with the confidence of having immutable, dependency-aware specifications.
Lock Specifications
Problem
AI constantly deviates from requirements, creating expensive rework.
Solution
Lock specs to create immutable contracts. Once locked, no one—not even AI—can change the requirements.
Outcome
Never waste 3 days debugging AI's wrong assumptions again.
Dependency Tracking
Problem
Building out of order causes integration nightmares and merge conflicts.
Solution
Visual dependency graph enforces correct build order. Can't implement child until parent is ready.
Outcome
Ship with 100% confidence—no more edge-case code drifting through reviews.
Category Organization
Problem
Messy, unstructured specs lead to confusion and missed requirements.
Solution
Organize specs into clear categories: Frontend, Backend, APIs, Database. Every file knows its place.
Outcome
Onboard new devs 2x faster with crystal-clear structure.
AI-Powered Generation
Problem
Manual spec writing is slow and error-prone.
Solution
AI generates implementation nodes from your description. Refine through conversation. Export complete context.
Outcome
Spec entire projects in minutes, not days.
Export Anywhere
Problem
Context gets lost when switching between tools.
Solution
Export locked specs with full context to Claude, Cursor, Windsurf, GitHub Copilot. Your specs travel.
Outcome
Never lose the 'why' behind the 'what' again.
Ship Faster
Problem
Unclear requirements lead to endless cycles of rewrites and bug fixes.
Solution
Spec-first workflow means less rework, fewer bugs, faster shipping.
Outcome
Build it right the first time, every time.

From Idea to Implementation
in 3 Steps
Stop wasting time fighting AI hallucinations. Get structured, exportable blueprints in minutes.
01
Describe Your App
Answer AI questions about your project. No technical jargon required—just describe what you're building.
- ✓Natural language input
- ✓AI asks clarifying questions
- ✓Automatic category detection
> "Build a SaaS for managing invoices with Stripe and Supabase auth"
02
AI Generates Blueprint
SCAFFOLD creates implementation nodes organized by category. Review, refine, and approve each file specification.
- ✓File-level specifications
- ✓Dependency graph visualization
- ✓Iterative refinement via chat
GENERATED: - /app/api/stripe/route.ts - /lib/auth/supabase.ts - /components/invoice-table.tsx
03
Lock & Export to Code
Lock approved specs to prevent drift. Export with full context to Claude, Cursor, Windsurf, or any AI code editor.
- ✓Immutable specifications
- ✓Full context preservation
- ✓Works with any AI tool
$ specdriver export --format=cursor > Exported 42 locked specs to .cursorrules
