Every quarter, procurement teams, CTOs, and founders make the same mistake.
They see a pricing page. They multiply the seat cost by the number of users. They call it a budget. Then, six months later, the invoice looks nothing like what they expected — and they can't quite explain why.
Overage fees. Implementation costs. Premium support add-ons. Renewal price bumps. The hidden cost of being locked in to a vendor you can't easily leave. The cost of not choosing the open source option because no one priced it properly.
This is the problem the SaaS Cost Analyzer was built to solve.
What It Does
The SaaS Cost Analyzer is an AI skill for Claude that turns any software evaluation into a structured, objective total cost of ownership analysis. Give it a pricing page URL, a list of tools you're comparing, your expected usage, and your growth projections — and it builds the full picture.
It doesn't just tell you what something costs today. It tells you what it costs at scale, what you're risking by choosing it, and which option wins — with the maths to back it up.
And it does this across SaaS tools, open source software, AWS and Google Cloud Marketplace listings, and everything in between.
What's Under the Hood
The Detail That Changes Everything
Most cost comparison tools treat open source as free. They shouldn't. And they treat compliance as a footnote. It isn't.
The SaaS Cost Analyzer starts from a different assumption: every option has a real cost, and some options aren't available to you at all.
If your organisation requires EU data residency, a vendor with US-only hosting isn't a cheaper option — it's not an option. The skill eliminates it before the first number is calculated. What's left is a clean, honest comparison of what's actually available to you.
And for open source? Whether you're evaluating PostgreSQL, n8n, Elasticsearch, or anything else — it finds the managed service providers, pulls their pricing, models your usage, and compares it fairly against commercial alternatives. No more "it's free" handwaving in budget conversations.
When to Use It
The skill triggers automatically when you're having a software cost conversation — you don't need to name it explicitly. But here are the moments it's most valuable:
This Is Skill #002
When we shipped the Website Policy Drafting Skill, we said it was only the beginning. We meant it.
AgentNXXT is Autonomyx's dedicated agents department — and our mission is to build a library of AI skills that make Claude dramatically more useful for the specific, high-friction workflows that teams deal with every day. Not general-purpose chat. Specialist agents that do real work.
The SaaS Cost Analyzer is Skill #002. It's open source, free to install, and built to be extended. If you have a use case it doesn't cover — a compliance framework it should know about, a marketplace it should check — open an issue or submit a pull request.
More skills are coming. If you want to know when they drop, follow AgentNXXT on LinkedIn.
