Service Description

FunctionFlow is a visual function auditing tool that helps developers visualize and audit serverless functions by displaying them as node-based workflows. The service:

• Connects to your GitHub repositories via OAuth
• Detects serverless functions in your code (Vercel, AWS Lambda, Google Cloud Functions, etc.)
• Analyzes functions using AST parsing (primary method) and AI-powered analysis (for complex functions)
• Visualizes functions as interactive node-based workflows similar to n8n or BuildShip
• Caches workflow visualizations to avoid redundant analysis
• Allows you to drag and reposition nodes for custom layouts
• Provides function analysis and auditing capabilities
• Supports background loading - functions continue analyzing even if you navigate away

How It Works: FunctionFlow uses a two-step analysis process. First, it attempts to parse your code using static AST (Abstract Syntax Tree) analysis. If the function is too complex for AST parsing, it uses Claude Opus AI to reconstruct the workflow. Results are cached using code hashing, so functions are only re-analyzed when the code changes.

User Accounts

• You must authenticate with GitHub to use the service
• You are responsible for maintaining the security of your account
• You must be at least 18 years old to use the service

• Pro Tier: 100 workflow analyses/month for $7.99/month
• Enterprise Tier: Unlimited workflow analyses for $19.99/month

Important Notes:

• Only new AI analyses count toward your limit - viewing already-synced workflows is free
• If an AI analysis fails or is cancelled, the usage credit is returned to your account
• Subscriptions automatically renew monthly
