fatsaas.com Diagnose my stack
SaaS spend diagnosis · vendor-neutral

Your SaaS stack is bleeding money.

Most teams pay for the same job two or three times, and rent tools they could own for less. Get a verdict on every line of yours: keep it, cut it, or own it. Two minutes, on screen, free.

Either works: a website is enough, we only need the domain to look up your stack. Nothing is emailed and no account is created.

Modeled from public list prices for a typical stack this size. Directional, not your invoice: switch sizes above, or run it on your real tools.

The verdict

Three answers, each with its reason.

Every line of the stack gets one. The reason is on the page, so you can check the model’s work instead of taking its word for it.

Own it

Rent you could stop paying

A tool your team uses a sliver of, at a seat count that makes the rent large. A fixed-fee replacement you own, when it pays for itself inside 24 months of the rent. Only then.

Often: project tracking, a support desk, scheduling, reporting.

Cut

Paying twice for one job

Two or three tools doing the same work. Keep one, retire the rest. The model prices the range; which tool survives is your team’s call, never the model’s.

Often: file storage, video, chat, docs.

Keep

Cheaper to rent than to own

Infrastructure, systems of record, and anything with compliance attached. The verdict says keep and means it, whatever the bill says.

Often: email, CRM, payroll, accounting, identity.

How it works

From a web address to a verdict in two minutes.

Detect

We read your public DNS and homepage for the tools you actually run: mail, chat, support, scheduling, identity and more. What we confirm is marked as fact.

Model

The rest is modeled from your company size against public list prices for 44 tools in 17 categories. You correct it: tick what you pay for, untick what you don’t.

Decide

Every line gets a verdict and its reason. Take it into your own renewal review, or hand it to tightsaas for the plan and a fixed quote.

One operator · three tools

Three separate tools, one operator.

Each is bought, priced and run on its own, and each is worth doing by itself — none of them is a prerequisite for another, and there's no order you have to follow. Together they compound: every replacement ships agent-ready, and the rent a leaner stack stops paying funds the agents that work on it. That's an option, not a gate.

Estimates use public list prices across 44 tools. Directional, not your invoice: you refine them on the next screen, and the consult produces the real, guaranteed number.
