I am having 500k rows of data I am looking to host it for free. I have no technical background skills.
Hello @Iampavi, welcome to the Baserow community 
The best option would be to self-host Baserow. This way, you won’t be limited in the amount of data you can store. For non-technical users, we recommend using Cloudron for self-hosting. Cloudron takes care of the technical aspects behind the scenes, so you don’t need to run commands through your terminal or anything like that.
Hope this helps!
