The majority of startup businesses have a low barrier to entry due to the nature of limited resources they have (unless you have a lot of capital to inject which are the exceptions). So don't feel alarmed that your idea/concept is relatively easy to replicate, most are.
The areas you need to focus on are the ways you can differentiate:
'Low barriers to entry' brings about 'brutal competition'. It's as simple as that. Food preparation is one of the classical examples. In most countries more or less anyone can open a fast food place or an restaurant with a minimum of formal training. So lots of people do, and prices are under constant pressure as a result.
If so, what have you done to overcome this?"Be better than the competitors." How to do that as your question is presented, absent any constraints or specifics about the market, is impossible to answer here.
