Developers are divided between migrating to third-party harnesses like Pi for their customizability and control, versus staying with native tools like Claude Code due to concerns about stability, security, and vendor restrictions. The strongest disagreement centers on whether the flexibility of open-source harnesses outweighs the operational risks of manual configuration and potential Terms of Service violations.

Great to see what you're doing there, but speaking as a 30-year hardcore C++ veteran (to the extent of creating my own C++ GUI framework: https://juce.com)... When I was writing a code agent (https://github.com/juggler-ai/juggler), there's no way I'd have used C++ for an agent GUI!
Agent UIs are all markdown, HTML, big scrolling lists, text flow, unicode chars, and all the other stuff that C++ frameworks are terrible at, but which is a doddle in HTML/CSS/JS.. You are a brave man!
In Prospero: A new coding harness for a more civilized ageYou're not alone - I also revolted against the TUI crowd and created my own GUI-centric harness juggler (https://github.com/juggler-ai/juggler). Might be up your street. If you're not too involved in your own project, maybe help out on mine :)
Honestly, I just don't get the TUI obsession, other than the fact that people are multiplexing many remote sessions over ssh. So my aim with juggler was to have an architecture that could do all the multi-client remote sessions with a GUI/websockets/Y.js sync etc.
In Prospero: A new coding harness for a more civilized ageYou can use your claude subscription just fine in open harnesses!
I make one (https://github.com/juggler-ai/juggler) and it'll auto-detect and use your claude CLI. I use that claude plan for 90% of my work, plus a bit of GPT, I just prefer to do it inside a nicer, less locked-in environment than claude.
There's really no moat around proprietary closed harnesses, it's trivial to jump between them, but people need to be aware that it's possible!
In The Agent SDKAs usual when there's a harness release by a billion-dollar company, I like to ride its coat-tails with a little plug for mine (https://github.com/juggler-ai/juggler) since my marketing budget is $0. Juggler usually gets a warm response from HN people because it's a bit more hands-on than most of them.
I'd be interested to hear whether the 'spec' stuff works or not. I've been pondering adding a plugin for juggler based on the fact that we're rubbish at writing specs: so instead, when you prompt it, it'd get the model to list the assumptions that it's making about the task. Then the user can spot and correct any incorrect assumptions, rather than expecting the user to provide correct specs. (Haven't actually tried this yet, just speculating)
In ThinkRail from JetBrainsI love that he designed a Jugglemeter.
Tbh, I was drawn to this post's headline because lately I've been having a great time using the Juggler coding agent. I recommend it if you're in search of something powerful with a web interface that works well on mobile devices: https://github.com/juggler-ai/juggler
In How Many Objects Can Be Juggled? (1997)Every few weeks Pi hits #1 here and I quietly grumble "mine does that too, but with lovely graphics.", so I'm saying it out loud: https://github.com/juggler-ai/juggler
Like Pi, it's plugins all the way down, provider-agnostic, minimal system prompts, threaded sub-agents, code-mode, multi-client remote sessions, worktrees, a context window you can actually see and edit, etc etc
Where Pi is way ahead is the plugin ecosystem, and that takes people, which is hard to get amid the current deluge of agent action. So if there's any spare oxygen trailing off this thread, I'd love any Pi-heads who fancy a bit of GUI action to come and kick the tyres..
In Pi 1.0Show HN: Juggler – an open-source GUI coding agent, by the creator of JUCE
Hello HN, I don't post on here much, but wanted to get some eyes on a new project I'm just launching. I think we definitely need one more AI code agent..
I'm a long-term C++ dev, and over 30+ years I've created some successful audio dev tools (JUCE, the Tracktion DAW, the Cmajor DSP language). All of these came from me getting annoyed with something I had to use, and deciding to have a go at my own take on whatever it was.
So Juggler is my attempt at an AI code agent, after spending too many hours loving what the models could do, but hating the CLI experience, and having some opinions of what a better UX might be for this stuff.
Lots more blurb on the website and github, but a quick tech dump which might grab your attention if you're into these things:
A session is a document, not a log file. Each conversation is a Yjs CRDT tree. It can b

ranch into sub-threads (recursively), and you can drill down, backtrack, edit, undo/redo, and inspect everything: tool calls, approvals, and the raw context JSON going to the model, etc. The UI is based around Finder-style Miller columns rather than a big doom-scroll, and is quick to navigate.
Because it's a CRDT behind a local web server, multiple clients can attach P2P to a live session: the native desktop app, a browser tab, or your phone. Run the headless server on the box where the code lives, view it from wherever.
Almost everything is a JavaScript plugin: every item in the context (read/write/bash/etc.), the LLM loop strategies, slash commands, and their UIs. You can inspect, fork, or replace any of them. I don't do much agent customisation myself, but lots of people do, and I'd love to see what they think of with this plugin API.
Go backend, Wails for windowing (no Electron), plain type-checked JS (strict JSDoc), Yjs for the documents. Usual BYOK provider support: Claude (CLI or API), OpenAI/Codex, Gemini, Ollama, OpenRouter, DeepSeek, etc.
The app's AGPLv3; the extension SDK and bundled extensions are Apache-2.0, so extensions have no copyleft strings attached. No signup, no telemetry, trying to make it frictionless for people to try it out..
It's very much a beta, and is a one-man side project. It hasn't yet had a proper kicking from the real world, but I'm confident some people with similar preferences to my own will like it!
