Kairos

Why?

Because I want one single chat app for every model and every conversation.

But aren’t there already thousands of apps like this out there? That’s true. I used Open WebUI for a long time, but it’s really heavy on both the client side and server side. It’s bundled with local model support, so that makes sense. But I don’t need all that. I just need a client that stores all my conversations and lets me chat with models via API.

There are some that resemble this, but they are either not open source, too feature-heavy, or I just don’t like the UI.

How?

I came across webclaw, which is a simple client for OpenClaw. I liked the UI and decided to extract the frontend UI and write a new backend in Go for it.

Kairos keeps the interface minimal while still making long conversations easy to navigate.

Current state

It supports OpenAI-compatible providers. Only chat completions are implemented right now, so there is no tool use yet, which is indeed a flaw. However, I don’t have time for that yet, and the current state is already good enough for me most of the time.
