Golang SDK

[mattsp1290]

I saw golang was on the roadmap, but didn't appear to have any work towards it committed yet. I've started working on this on my own. But overall I would love to be able to interact with AG-UI in golang to build powerful CLI tools.

Hey @mattsp1290, this is great! Thanks for adding the Issue and starting the work.

Golang has been added to the roadmap and I assigned it to you.

Please keep us updated on the progress.

Fantastic! Are you able to share any work-in-progress? I stalked your fork https://github.com/mattsp1290/ag-ui but didn't see any golang branches 🙂

Hey @mattsp1290, just checking in here. Do you have any questions or need any support from our end?

ttps://github.com/mattsp1290/ag-ui is indeed fork I have made. I have a fully featured vibe coded go-sdk implemented there.

I have two more features I'd like to vibe code before I start opening PRs. My current plan is to start a new branch once that is finish and bring it in in small reviewable components. If I opened a PR against my current vibe coded output, it would be 500k lines changed across 1500 files. A lot of these come from markdown files Claude leaves for itself. But I still suspect there is a lot of cruft in place. I'd like to make sure when I do open a PR it is something I can be proud to put my name on.

Apologies for the length of time this taking. Been making slow progress on this every day. I have been hitting a point where Claude is slowing down due to complexity and scope. Based on the current rate of work by Claude, I would expect I'll be making my first PR against AG-UI by end of next week.

I have been able to get a working example for both server and client on my fork. I need to do a refactor to get the go module named appropriately to match github.com/ag-ui-protocol/ag-ui. Waiting on the repository reorganization before doing this refactor.

This is great @mattsp1290!

Would you be up for a simple, short demo at next week's Working Group?

[mattsp1290]

I'm working on a simple demo using https://github.com/charmbracelet/bubbletea that will demonstrate client, server and calls reaching OpenAI or Anthropic. Hoping to be able to present this at the Aug 28th working group.

Nice! Are you able to link to the WIP source code for that demo? Would love to take a look

@sirianni I have a working demo at https://github.com/mattsp1290/october-talks-2025/tree/main/example

Server side code for calling an LLM and sending data back to the client over SSE https://github.com/mattsp1290/october-talks-2025/blob/main/example/server/internal/agentic/agentic.go

Client code to send a message to the server and subscribe to the SSE stream https://github.com/mattsp1290/october-talks-2025/blob/main/example/client/cmd/main.go#L179
