The products are almost exclusively free with some exceptions: products where there is no free alternative, good products that offer a lifelong license, and exceptional products.
Please inform me for dead/false links, and give suggestions for new applications with the form located at the end of this list. I react to every correction and suggestion, although I may not answer all of them explicitly. This list is updated approximately twice a week, if needed. So, if your suggestion does not appear to the list immediately, it does not mean it has been omitted.
