I have seen multiple HN threads and opinions both positive and negative regarding the usage of agent frameworks such as LangGraph, Mastra etc.

I wanted to post this question to try and spark a good discussion to try and capture some concrete and tangible points arguing both sides, as so far most of the comments people make so not give much evidence for their views.

Obviously we must bear in mind that frameworks can be very small[1] and very large[2], so need to be thought of differently.

For those "rolling your own" please share as much detail as possible.

Both. Roll your own using a protocol like MCP or A2A so you can integrate other tools and agents.
