And the question that goes with that of the title is: how to have a quality and free house plan? Easy: just know how to draw a house plan!
I will respond with nuances. Indeed, in a conventional store, if you buy a connected speaker, the price is correlated with the quality. Naturally, a large and heavy speaker like Google Home will generally be more expensive than a small speaker because of better quality. It is valid for all objects of daily life. A Ferrari type car will be more expensive and of better quality than a Peugeot 109 or a Fiat Tipo (sorry for the manufacturers …).
And in digital?
In digital, it’s very different. Simply because the economic models are different. In digital, you can have an essentially free service. In one case, it will be completely free and the company that produces this service will live on advertising (we often see this with bloggers from Youtube). In another case, the service will be free, and the company that produces this service will live thanks to additional functionalities accessible through paid subscription. In both cases, the quality of the service must be important or people will not come to the site.
The answer of the question
So, to answer the question of the title: yes, we can have a quality and free product. But you should never forget that if the business model of the company does not work (not enough ads on the site because too many people put an ad blocker, or not enough people who take a paid version with new features) then the site can stop, which happens regularly.
And the solution
This is why we have chosen to put this free, archiplain house plan software online. We offer you essentially free software, of very good quality. And if you want new features, you can take a paid subscription that you only pay once (no renewal every month. You buy it today, and in 6 months or more, the account will still be active).
