Provides quick and easy containerization, but documentation is not very user-friendly
Milvus' documentation is not very user-friendly and doesn't help me get started quickly. Chroma DB provides super user-friendly documentation, enabling new users to get started quickly. Chroma DB's setup doesn't have many dependencies, whereas Milvus usually comes with some dependencies because of the way it needs to be deployed. Unlike Milvus, it's very easy to do POCs with Chroma DB.
Ankit_Yadav - PeerSpot reviewer

Building full web apps without managing my own backend has become simple and cost effective
I think the support system can be better because after Supabase Vector stopped working in India, there is no support. Nobody knows how to deal with the database now. The naming structure is a little difficult. If you are naming a table, the guidance is sometimes not clear. It's a very simple feature to add sometimes but the process is very difficult. When I'm in Supabase Vector, there is a feature where I have to create a table. At the start, for newcomers, it's difficult, and then it becomes hard. You have to look for the documentation and YouTube videos to understand how it works. Supabase Vector stopped working in India due to some government guidelines, so I have to switch with something else now.

Pros

"Milvus has good accuracy and performance."
