n8n workflows become unmaintainable at scale due to lack of complexity analysis, refactoring guidance, or auto-documentation tooling.
What is it?
n8n power users scaling past 20 workflows hit a wall: undocumented flows, circular dependencies, and zero testability turn every new hire into a liability. FlowArchitect ingests n8n workflow exports, scores cyclomatic complexity, detects anti-patterns like mega-flows and hardcoded credentials, and outputs a prioritized refactor plan with suggested sub-workflow splits. Teams get an auto-generated Markdown doc per workflow plus a complexity dashboard. Buildable now because n8n exports are plain JSON and Claude handles graph analysis trivially.
Why now?
n8n hit 60,000 GitHub stars in May 2026 and self-hosted adoption is exploding, but no tooling exists for workflow code quality — the gap is wide open right now.
- ▸Complexity scorer that parses n8n JSON and outputs a 1-10 risk score per workflow.
- ▸Anti-pattern detector flagging hardcoded values, mega-flows over 30 nodes, and missing error branches.
- ▸Auto-generated Markdown documentation per workflow with node-by-node plain-English summaries.
- ▸Refactor suggestions showing exactly which node clusters to split into sub-workflows.
Target Audience
SMB automation ops teams and n8n power users managing 20+ workflows, estimated 40,000+ active n8n self-hosters.
Example Use Case
A 3-person ops team uploads 50 exported n8n workflows, gets a complexity leaderboard showing 8 critical spaghetti flows, and refactors them in a sprint instead of a quarter.
User Stories
- ▸As an automation ops lead, I want to upload all our n8n exports and get a complexity ranking, so that I can prioritize which workflows to refactor this sprint.
- ▸As a freelance n8n developer, I want auto-generated documentation for each workflow, so that I can hand off projects to clients without writing docs manually.
- ▸As a CTO onboarding a new ops hire, I want to see anti-pattern flags across all our workflows, so that I can reduce the risk of the new hire breaking production.
Done When
- ✓Upload: done when user drops a valid n8n JSON file and sees a complexity score card within 15 seconds.
- ✓Anti-pattern detection: done when at least one hardcoded credential or mega-flow flag appears on the result card for a qualifying workflow.
- ✓Documentation export: done when user clicks Export Docs and receives a downloadable Markdown file with node-by-node summaries.
- ✓Billing: done when Stripe checkout completes and user immediately gains access to unlimited uploads without a page refresh.

Launch & Validation Plan
Post in r/n8n offering free analysis for 5 workflows, collect 10 responses, validate pain before writing a line of code.
Customer Acquisition Strategy
First customer: DM 10 active contributors in the n8n Discord offering free unlimited beta for their team in exchange for a 30-min feedback call. Ongoing: r/n8n posts, n8n community forum, ProductHunt launch targeting automation ops tag.
What's the competition?
Competition Level
Low
Similar Products
FlowAudit covers automation health broadly but not n8n-specific complexity scoring. n8n itself has no built-in complexity analysis. WatchdogFlow monitors runtime but not code quality.
Competitive Advantage
Zero competition in n8n-specific tooling, purpose-built parser understands n8n node types natively, not generic graph analysis.
Regulatory Risks
Low regulatory risk. Workflow exports may contain sensitive data — recommend on-premise mode in V2 and document data handling clearly.
What's the roadmap?
Feature Roadmap
V1 (launch): upload, score, anti-pattern flags, Markdown export. V2 (month 2-3): team dashboard, weekly digest email, sub-workflow split preview. V3 (month 4+): live n8n API sync, CI/CD webhook, white-label for agencies.
Milestone Plan
Phase 1 (Week 1-2): parser, scorer, Claude integration, demo seed data ships. Phase 2 (Week 3-4): auth, Stripe billing, dashboard live with 5 beta users. Phase 3 (Month 2): 10 paying teams, ProductHunt launch.
How do you build it?
Tech Stack
Next.js, Claude API, Supabase, Resend — build with Cursor for parser logic, v0 for dashboard UI
Suggested Frameworks
-
Time to Ship
2 weeks
Required Skills
JSON graph parsing, Claude API prompting, Next.js, Supabase.
Resources
n8n docs on workflow JSON schema, Anthropic API docs, Supabase quickstart.
MVP Scope
app/page.tsx (landing + upload CTA), app/upload/page.tsx (drag-drop workflow uploader), app/dashboard/page.tsx (complexity leaderboard), app/api/analyze/route.ts (Claude analysis endpoint), lib/parser.ts (n8n JSON graph extractor), lib/scorer.ts (complexity scoring logic), lib/db/schema.ts (Drizzle schema), components/FlowCard.tsx (per-workflow result card), .env.example (required env vars), seed.ts (3 demo workflows preloaded).
Core User Journey
Upload n8n export -> see complexity score in 10 seconds -> read refactor suggestions -> share dashboard with team -> upgrade for unlimited uploads.
Architecture Pattern
User uploads n8n JSON -> Next.js API route -> lib/parser extracts graph -> lib/scorer computes complexity -> Claude API generates refactor suggestions -> results stored in Supabase -> dashboard renders leaderboard.
Data Model
User has many UploadBatches. UploadBatch has many Workflows. Workflow has one ComplexityReport. ComplexityReport has many RefactorSuggestions.
Integration Points
Claude API for analysis and doc generation, Supabase for storing results and user data, Resend for weekly digest emails, Stripe for billing, Vercel for hosting.
V1 Scope Boundaries
V1 excludes: live n8n API connection, visual graph rendering, team collaboration comments, CI/CD webhook integration, mobile app.
Success Definition
A paying ops team uploads their entire workflow library, receives a refactor plan, and renews after month one without any founder hand-holding.
Challenges
Distribution is the hardest problem — n8n users are technical and skeptical of new tools, requiring trust-building in their Discord and Reddit communities before any paid conversion.
Avoid These Pitfalls
Do not build a full IDE or visual editor in V1 — text output with scores is enough to charge for. Do not skip seeding demo workflows or the dashboard looks empty on first open. Finding your first 10 paying customers takes longer than building the parser — budget 3x more time on Discord outreach than development.
Security Requirements
Supabase Auth with Google OAuth, RLS on all user tables, uploaded JSON files deleted after analysis, rate limiting 20 uploads/hour per user, GDPR data deletion endpoint required.
Infrastructure Plan
Vercel for Next.js, Supabase for Postgres and auth, Cloudflare R2 for temporary JSON storage, GitHub Actions for CI, Sentry for error tracking.
Performance Targets
100 DAU at launch, analysis API response under 8 seconds including Claude call, page load under 2s, no caching needed at V1 scale.

First Run Experience
On first run: 3 demo n8n workflows are preloaded showing low, medium, and high complexity scores. User can immediately click any workflow card to read refactor suggestions and export Markdown docs. No manual config required: demo data seeded, Claude API call fires on preloaded data.
How to build it, step by step
1. Define Drizzle schema for User, Workflow, ComplexityReport in lib/db/schema.ts. 2. Build n8n JSON graph extractor in lib/parser.ts that pulls nodes, edges, and credentials references. 3. Write lib/scorer.ts computing cyclomatic complexity and anti-pattern flags. 4. Create app/api/analyze/route.ts calling Claude with scored graph data for refactor suggestions. 5. Build app/upload/page.tsx with drag-drop JSON uploader using react-dropzone. 6. Build app/dashboard/page.tsx rendering a complexity leaderboard per workflow. 7. Add Supabase Auth with Google OAuth and RLS on all tables. 8. Wire Stripe billing with $49/month plan and upload count gating. 9. Seed 3 realistic demo workflows in seed.ts so first-run dashboard is not empty. 10. Deploy to Vercel and verify the full upload-to-refactor-plan journey without any manual steps.
