Exchanges of code (libraries, scripts, components...) Do they exist?

Question

Programming

Are there resources in nature a la photostocks (“codestocks”) for programmers?
Here, for example, I have accumulated a lot of my own efficient controls under WPF, but naturally there are not enough for Telerik packs. There was an idea to sell them. It makes no sense to fence a separate site, it is necessary to develop, sales are single.
Resources like SoftKey and AllSoft are designed for ready-made products and are aimed at ordinary users, there is a small controller and no one will look for it.
But something like a “kodobank” working on the principle of drains would fit perfectly, laid out the controllers, at 10 green prices, you see - a penny is dripping.
I found only one more or less intelligible resource:
codecanyon.net/
but everything there is more Web-oriented.
Maybe I’m generally confused by this in vain, because it’s easier for everyone to write themselves (google) than to buy?

Answer 1

It's easier to search for the required GPL code on the same Google code.
Buying / selling software in our time is not comme il faut.

Answer 2

If there is no site, then upload it to github along with the DONATE file. My colleagues and I did this - spectrum-soft.ru/index.php/articles/7-highload/15-poco (see at the bottom of the page)

Answer 3

Alternatively www.hotscripts.com/

Answer 4

codecanyon.net
