which is not to say any of them got it right or wrong, but it is by no means "missing". the big question w all of them is do they deliver enough value to last. kudos to those who at least try, of course

We originally were wrapping AI SDK, but that confused people who wanted to use both, so we decided to make the API more explicit, eg:

import { Agent } from "@mastra/core/agent"; import { openai } from "@ai-sdk/openai";

export const myAgent = new Agent({ name: "My Agent", instructions: "You are a helpful assistant.", model: openai("gpt-4o-mini"), });

https://typedai.dev is another full-featured one I've built, with a web UI, multi-user support, code editing agents, CodeAct autonomous agent

Mine is written in TypeScript and I still think it's more ergonomic than anything else I'm seeing in the wild. Maybe there's finally an appetite for this stuff and I should release it. The Mastra dashboard looks pretty nice, might take some notes from it.
