How LagLab actually works
No marketing language here — just what the tool does and how it stays free.
What the checklist is
LagLab is a rule-based checklist, not an AI or a magic scanner. Your answers (game, device, RAM, internet type, and the problem you're seeing) are matched against a fixed set of suggestions written in plain language. Every suggestion is something you can read, understand, and try yourself.
What it isn't
It doesn't scan your PC, install anything, or measure your real FPS or ping. The "estimate" score you see is based on your answers, not a lab measurement — it's there to give you a rough sense of how much is fixable for free versus how much is a hardware ceiling.
What happens to your answers
Nothing. The checklist runs entirely in your browser. Your answers are not sent to a server, stored, or used for anything beyond generating the result you see on screen.
How this stays free
LagLab doesn't charge for the checklist and doesn't require an account. Some hardware suggestions in your results link to specific products (like RAM or a router) through affiliate links — if you buy through one, LagLab may earn a small commission at no extra cost to you. The site may also show a small number of ads. Neither changes what the checklist recommends; the suggestions come first, the links are just where to act on them.
Why there's no signup
An account wouldn't add anything to a tool that doesn't store data or track progress over time. If that changes in the future — for example, saving your results to compare later — it will be opt-in and clearly explained, not required to use the free checklist.
