How We Test

Our ratings are only as trustworthy as the process behind them. Here is exactly how we test and score every tool on SaaS Stack AI.

We use the product

We do not review tools from a feature list or a vendor demo. We create a real account, build a real project, and put each tool through realistic, day-to-day tasks. Our reviews include our own screenshots, not stock images supplied by the company.

We score on five weighted criteria

  • Output quality (30%) — how good are the results in real use?
  • Ease of use (20%) — how quickly can a new user get value?
  • Value for money (20%) — is the price fair for what you get?
  • Integrations (15%) — how well does it fit into a wider stack?
  • Support and documentation (15%) — can you get help when you need it?

We re-test and date everything

Software and pricing change constantly. Every review shows when it was last tested, and we update scores when products change materially.

Our scores cannot be bought

We earn affiliate commissions, but commission rates never influence a score or ranking. See our Affiliate Disclosure for the full picture.
