FAQ

Questions About Amazon Tools Without Subscriptions

Why do most Amazon FBA tools charge monthly fees?

Most Amazon tools require servers, data pipelines, and constantly updated databases — which cost money to maintain, justifying a subscription. Kill-or-Go runs entirely in your browser using data you enter yourself. There is no server to maintain. A subscription model would be charging you for infrastructure that does not exist.

Can I use Kill-or-Go alongside Helium 10 or Jungle Scout?

Yes, and this is the recommended workflow. Use Helium 10 or Jungle Scout to find a keyword with good search volume and revenue potential. Pull the top 10 listings. Enter them into Kill-or-Go. Get your structural verdict before you brief a supplier or order samples. They work together — Kill-or-Go is the decision layer that comes after your research.

How do I get access after I buy?

Checkout is through Gumroad. The moment your payment goes through you get an instant download — no account to create, no waiting, no onboarding. The tool runs offline in your browser, so you can open it and get your first verdict within a minute of purchase.

What happens when Kill-or-Go gets updates?

Future updates are distributed to existing customers at no additional cost. One payment covers the current version and all future improvements.

One Payment. No Monthly Bill. Permanent Access.

While other tools charge $99–$199 per month, Kill-or-Go costs a single one-time payment and runs forever — offline, privately, without renewal.
