I use Google's Agent Development Kit (adk)[0] at work and enjoy using it quite a bit.

Certainly not better… it’s a one person project after all… but I have a workflow in typescript solution, not quite ready for prime time at workglow.dev. I’ll have AI agent stuff both in the framework and the UI (it’s feature flagged off at the moment) in January/February time frame.

The site above only runs local in browser models and uses a local user account. So it’s easy for infinite people to play with and costs me nothing to host.

It’s still a ways away from a Show HN post, and is more capable with remote frontier models, or with gguf over onnx (maybe?) whenever I get the local app out.

TanStack AI is open source and almost ready for production: https://tanstack.com/ai/latest

I have a friend who works at Mastra[0].

Got part way through their tutorial, seemed okay. Haven't used it in prod, though.
