What HN said

What people liked

  • Clean UI and good design.

    From 2 comments
    • UI is clean. could install in Mac. Adding context files at the top is clean. It worked. Currently I use zed, vscode (for UI). along with claude, codex, Hermes. Not sure If I will…

    • This is really nice, thanks for sharing! If you don't mind a little feature request, I'd love to have a "thinking level" selector on the GUI for models that have it. I really…

  • Tree and subthread structure is a novel idea.

    From 2 comments
    • This looks really interesting and a unique take on the AI agent orchestration. I think we need a bunch of experiments in this area as it's clear we are entering a new paradigm…

    • This looks nice, and I like the more opinionated take on how "communicating" with an agent should work. The post talks a lot about what this is and how it works. I'm curious,…

  • Open source AGPL, built without Electron.

    • Really glad to see an harness other than Pi that seems to be non-vc-backed FOSS and by a competent maintainer Edit: seems like the remote connection feature may not work...

Objections

  • Requires WebKitGTK, causing install and sandbox problems on Linux.

    From 2 comments
    • For running headless is it possible to not require installing libwebkitgtk-6.0.so.4

    • Seems to work when I click the juggler.app in Ubuntu 24.04 (Noble Numbat) GNOME's desktop. Running same app via terminal does not launch the app. Appear to be a sandbox issue…

  • Limited provider list, no custom provider management for BYOK.

    From 1 comment
    • Sorry but it's not real BYOK to me as there is no UI/method provided to modify the providers, instead the app provides limited provider list and only allow custom API keys. I…

  • Provider API bugs such as DeepSeek reasoning_content error.

    From 1 comment
    • Having now given it a quick spin, I like the UI concept and could definitely see myself working with this. I ran into a bug(?) almost immediately though, I hooked up Deepseek 4…

Requests

  • Support for ACP.

    From 2 comments
    • ACP support would be a big deal and would make this a real contender for me. It looks super nice, but the idea of re-writing my Pi plugins is a real blocker. I’m generally happy…

    • Is this using ACP?

    • Interesting. Just opened it up to use, while I had a codex terminal session running - my first instinct was to want to see my pre-existing open session in the GUI instead and be…

  • Does it work with an Anthropic key or Claude Agent SDK login?

    From 2 comments
    • Nicely done! Would you consider adding an Agent SDK login for Claude for those who don't have an API budget and want to avoid potential issues with Anthropic's capricious…

    • Great work, it is very funny that I did just the opposite :) Got fed up with Zed, Cursor, and the other GUI agentic tools and created a console TUI agent for my own use.
