I've been building with Mastra for a couple of weeks now and loving it, so congratulations on reaching 1.0!

It's built on top of Vercel AI elements/SDK and it seems to me that was a good decision.

My mental heuristic is:

Vercel AI SDK = library, low level

Mastra = framework

Then Vercel AI Elements gives you an optional pre built UI.

However, I read the blog post for the upcoming AI SDK 6.0 release last week, and it seems like it's shifting more towards being a framework as well. What are your thoughts on this? Are these two tools going to align further in the future?

Never ask a woman her age, a man his salary, and an agent framework developer his long term plans

Have a ton of respect for the AI SDK team. Initially we only used AI SDK model routing, but now we also have our own built-in model routing as well.

I see each of us having different architectures. AI SDK is more low-level, and Mastra is more integrated with storage powering our studio, evals, memory, workflow suspend/resume etc.
