This is a backend written in go that's wire-protocol compatible with the (catchy named) Vercel AI UI SDK; which is an SDK for helping to build AI chat apps. The original Vercel AI SDK backend is in typescript.

I think they really missed the opportunity to add in resumable streaming after a dropped SSE connection, or multi-device support. Because these SDKs are easy to drop-in to your applications, but hard once you actually try and build resilient systems on top of them. Systems that can heal from dropped connections, or support multiple users or multiple devices.

ADK seems like a better thought through SDK family, I use Go, Py is most mature, also TS and Java. The docs still need a lot of work to cover all the languages, it's pretty hit or miss right now, but one can also have a coding agent look at the source and an example for another language. Notably to your complaint, I have a coding agent that if the client drops, the llm/agent keeps working in the background. This requires it being set up as a server, which implies tool calls happen there instead of where the client is. I used Dagger as the "sandbox" more for easy time traveling / forking than being a sandbox. The well designed interfaces that allow custom implementations are what hooked me on ADK.

Agreed, ADK is really well designed. We’ve used it as the harness for our main product since about January and it’s been solid.

Instead of writing a Go converter to use it with AI SDK Elements, we added this client side and use ADKs SSE streaming and recovery out of the box.
