I build a project calculator web app for n8n / automation folks

The Problem
I freelance with n8n and the hardest part isn't building workflows — it's answering the question: "How much should I charge for this?"
There's no tool for it. I Googled. I searched the n8n community. Nothing. Every pricing discussion ends with "it depends."
So I built one.
What It Does
n8n Project Calculator — describe what the client needs and it gives you:

Estimated build cost (flat rate)
Monthly hosting breakdown (self-hosted vs cloud)
Complexity rating so you know what you're walking into

It uses AI to analyze the project requirements and generate a realistic estimate based on n8n-specific factors like node count, integrations, AI agents, and hosting setup.
Stack

Frontend: Next.js (scaffolded with Bolt.new)
Hosting: Vercel (free tier)
AI: DeepSeek API (serverless function)
Monthly cost to run: ~$0

Built in one day. Five rounds of visual review and bug fixing to reach production quality.
Who It's For

Freelancers doing n8n/automation work who need to quote projects
Clients/businesses trying to budget for an automation project
Anyone curious what workflow automation actually costs

Try It, save it, bookmark it, it might help you in the future
