Free SaaS Stack Audit
Review the tools you already pay for, find potential overlap, and decide what to keep, cut or replace.
Subscription creep is hard to see one tool at a time
Most software subscriptions make sense when they are added.
The problem appears later. A writing tool gains research features. A project-management app adds AI. Your CRM adds email automation. Another product is purchased for a single workflow. Each subscription still looks reasonable on its own, but the stack as a whole starts doing the same jobs more than once.
A SaaS stack audit looks at the collection instead of judging every tool separately. StackDiet helps you review that collection and identify places where two or more subscriptions may be covering similar work.
What does StackDiet look for?
The audit focuses on practical decisions.
- Potential overlap between tools
- Subscriptions that appear to cover similar jobs
- Opportunities to compare one tool against another before renewal
- Places where a smaller combination may cover the workflow
- Tools that should be reviewed as keep, cut or replace candidates
StackDiet does not know whether your team actually uses a feature unless you tell it. It does not invent missing information, and missing prices are not guessed. Use the result as a decision aid, then confirm the details that matter to you before cancelling or switching a service.
Keep, cut or replace — not “cancel everything”
The goal of a lean stack is not to have the smallest possible number of subscriptions. A tool that saves time, supports an important workflow or does something another product cannot do may deserve to stay.
Keep
The tool has a clear role and earns its place in the stack.
Cut
Its main job is already covered well enough elsewhere or it no longer solves an important need.
Replace
The workflow still matters, but another option may fit the stack better.
Add real prices when you know them
If you know what you actually pay, include the price when you describe your stack. That makes the audit more useful because the result can distinguish between a small duplicate subscription and a costly area worth reviewing first.
If you do not know a price, leave it out. StackDiet does not guess it.
Semrush — €140/month
Surfer — €99/month
Mangools — €49/month
The important part is that your real stack — not a generic example — drives the result.
Good times to run a SaaS audit
- Before a yearly or monthly renewal
- Before adding another AI subscription
- When several tools seem to do the same thing
- When software costs have grown gradually
- When a freelancer or small business has accumulated tools without a clear plan
- When you want to simplify a workflow before changing platforms
From audit to a leaner stack
An audit is useful only if it leads to a decision. After reviewing overlap, go back to the job each tool is supposed to do. Keep the products that cover important workflows. Compare the questionable ones. Remove or replace only when the alternative genuinely covers the work you need.
Frequently asked questions
What is a SaaS stack audit?
It is a review of the software products and subscriptions in a stack to identify overlap and make clearer keep, cut or replace decisions.
Does StackDiet cancel subscriptions for me?
No. StackDiet helps you review the stack and make decisions. You remain in control of any cancellation, purchase or switch.
Does StackDiet guess subscription prices?
No. If a price is missing, it should remain unknown rather than being invented.
Can I audit AI tools and normal SaaS together?
Yes. The point is to review the workflow as a whole, so AI tools and conventional SaaS products can be considered together.
Is the audit free?
Yes. StackDiet is free to use with no signup, no paywall and no paid report.
