Free, freemium, paid, open source: what the labels mean
Every tool in the library carries one of four pricing labels. Here is what each one promises — and what it does not.
Each tool in the library has a pricing label. They look simple, but they hide different trade-offs.
| Label | You pay | Typical catch |
|---|---|---|
| Free | Nothing | May have ads, or limits that change |
| Freemium | Nothing to start | Usage limits; best features are paid |
| Paid | A subscription or per use | No way to try it properly first |
| Open source | Nothing for the software | You need your own hardware or hosting |
Free
The whole product costs nothing. Ask how it is funded: research project, advertising, or a way to bring you to a paid product later.
Freemium
The most common model. The free plan is real but limited. Before relying on it, find out which limit you will hit first.
Paid
No permanent free plan. Look for a refund window or a short trial, and set a reminder before it renews.
Open source
The code or model is published and you can run it yourself. Free here means free of licence fees — not free of effort. You trade money for setup time, and you get privacy and control in return.
Which should you pick?
Start with freemium tools to learn what you need. Move to paid when a limit is costing you time. Consider open source when privacy matters or when you use something so much that subscriptions add up.
