# Do Not Use SaaSS Service as a Software Substitute (SaaSS) basically means outsourci ng computing. It is something like a "Web app", but those are not exactly the same. Because a web app can be just a software that ru ns on a web browser without the server side. Editing files (texts, images, videos, &c.), translating texts, and calculating equations on a website are SaaSS. Posting on a website and using a search engine are not. The problem is that it makes a blackbox. Or I could say, a backdoo r. It is worse than proprietary software. Even if the client side is free, you can't see what's really going on the server side. It doesn't matter if they say it's libre. You can't be certain that t he server actually uses the free software. Also there is not an ex ecutable file so that if the server closes, you can't use it anymo re. On the other hand, you can RUN a proprietary software at least . So how to examine a program on a website is SaaSS or not? It is ea sy. Just download the webpage and try to run on your web browser w ithout the internet connection. If it works, use it that way. If i t doesn't work, it is a SaaSS. So try to find an alternative. I re commend to just install a software on your computer because JS suc ks anyway. And you can use it without opening a web browser.
