WZ Vault · The Stack
Not a top 50. The ones marked in my stack are what I actually build, publish and sell with. The rest are tools in the same territory, worth a look when you have the problem they solve — with an honest note on when you need each one and, more often, when you do not.
Free companion
Every conclusion from all eight playbooks — 97 chapters, 46 pages, condensed to what you would write on a card. Free, no upsell on the way in.

The long version of what is on this list: what the work actually pays per hour, what a product nets after advertising, and which subscriptions earn their place.
Five jobs a solo operator actually has to do, the smallest set of tools that does each one, and the monthly total — including which subscriptions to delay until something is earning.
The arithmetic that decides whether a store is a business or a machine for converting savings into advertising — built line by line on a €69 product, with the order bump and the repeat purchase that make it work.
Eight AI side hustles, ranked by what they pay per hour once you count every hour — sourcing, learning, listing and the mistakes. Worked examples with the arithmetic shown.
