marketing or scientific

How can I get people to use a free web application I created to help developers like myself track and analyse files and lines of codes in a project? I use it often, and would really like for others to use it too as I think it's very useful.

you must

• design a market policy
• create a group in social media
• be member of niche groups and inform
• make noise, speak to youtube niche channels
• be a good student of the niche
• and more

I want to say a story, before 20 years was a Unix named Tru64, it was the best, but maybe had but marketing, then a bigger company it’s company, I think HP bought and now it is not used. So it survives the one who has a good marketing (department) NOT THE SCIENTIFIC BEST.focus on digital marketing
