Railway deployement


I’m new to cloud hosting and I’m pretty much lost on the pricing. I would like to host my strapi application with a postgre database on railway.app. I understood that it was much advised on this forum for its price and its ease of use. The application in question is a blog containing about fifty articles and will be used mainly to share my work. I don’t expect to have hundreds of thousands of visitors. With your experience, could you give me a range of what it could cost me per month?
I have a budget of maximum 20/month, can it be possible with the developer plan?

Thank you very much for your help.
