OpenChamber: An Agentic Development Environment

I prefer Paseo https://github.com/getpaseo/paseo, mainly because I have specific preferences for different harness + model combinations. For example, I like using ChatGPT models via pi, and GLM via Claude Code.

If you’re happy with OpenCode as the harness, OpenChamber is great. But if you prefer using different harnesses under the hood, Paseo is a better fit.

I installed it on my homelab and can access the same sessions from my MacBook or iPhone at any time. Been really nice to use so far.

Somehow reminds me of JetBrain's new Air [1] platform (still in beta I think) - make multiple agents working, monitoring, basic code and diff viewing.

Had to scroll all the way to the bottom to see that its a wrapper for OpenCode.

This actual functionality should be more explicitly stated, and should be described much sooner IMO.

Looks nice.

I have a number of these pieces in a binary I drop first thing on every agent computer: https://github.com/housecat-inc/scratch

Chat to code with an inspector to point at specific DOM sections, review diffs on the box, hand off to mobile, etc.

Makes me wonder where all this will end up. Or DIY win with hyper-personalized tools? Will one vendor become the center of gravity similar to VSCode in previous generation? Will there be a cottage industry of more opinionated tools?

I'm using Orca recently for both coding and as a terminal and like it a lot, seems this is very similar, just tied to a single harness?

It's funny / ironic how the whole agentic development boom has taken off in terminal environments, but now the orchestration / IDE layer seems to be all Electron / GUI apps.

Any suggestions for terminal UI versions of something like this?

It's nice but I get such memory leaks that I have to reboot my bacbook after a few hours of using it. Sticking to opencode gui for now.

Over 50 npm dependencies (dev and non-dev). Is this really how things are developed in 2026? After all what's happening (cyber security), is any developer out there running this kind of software just like that in their main machines without any concerns?

This looks pretty awesome, like almost exactly what I've been hoping for. Is it possible to run the sessions on a remote server to keep tasks running? I mostly work from my laptop and it's nice to fire off tasks to a remote server (mostly been Cursor Cloud Agents lately) and close my laptop, maybe check in from the app later.

First screenshot is of a phone.

Yeah I’m never installing a coding agent on my phone.

I really enjoy the sidebar style for organising work, I’m not sure why the OpenCode desktop app moved to browser-like tabs (horizontal ones, though tbh my browsers now have vertical ones ehh).

I wonder what JetBrains is doing. They had such a strong lead, but with the rise of AI, they seem to be heading down the same path as Stack Overflow.

Try codecast for a better version of this that works across all agent harnesses in one unified way.

is agent orchestration somewhere in your backlog?

This appears to be somewhat like Paseo, specialised for OpenCode under the hood?

Why use this over T3 Code?

OpenEverything

I have been using Opencode desktop, going to try out these other tools too

Sticky header with no background seems a bit awkward on mobile. The text overlaps.

Oh, I love the idea of a changes walkthrough. Maybe I'm old fashioned but I still look through all the code and prose that gets committed. In Orca, it took me about half an hour to even find the diff view (hidden behind a panel, activated on the top right)

I've said it before and I'll keep on saying it: the churn in new dev interfaces it's super exciting. Can't wait to see what next week brings.

This looks neat. How is this different from Jetbrains Air?

Since this page is clearly made with AI, someone deliberately prompted to add scroll hijacking for some reason, despite it being known to be bad UX.

Is saying "XXX: An Agentic Development Environment" already sufficient to get to the front page of HN? I guess no differentiation is even required in this category, huh?

Seems like another clone of Conductor, though this one has a serious amount of feature creep (supporting so many platforms will add a ton of extra complexity), and on OpenCode SDK only.

As a simpler desktop-only multi-platform option, I can highly recommend Termic (https://github.com/simion/termic). It just runs existing TUI coding agents (so Codex, Claude Code, OpenCode, etc) and manages them in sandboxed git worktrees. You get a real PTY to manage agent in, lets you see when one is working or has paused, plus a terminal, "changed git files", even in-line-code comments you can feed back to the agent. It's a good design, works well, the main dev is working very quickly on improvements, and they're responsive to issues and PRs.

Looks interesting, might try it out. I have to ask, did you really need to hijack my scroll behaviour?

From now on I swear if I launch a new product I will call it ClosedXXX

This looks very nice and well done. Good job! Okay, I'm going to have a tongue-in-cheek rant now.

OpenChamber, OpenAI, Open WebUI, OpenDoor, Open weights, OpenTable, OpenClaw, Open This, Open That. We're increasingly diluting the meaning of the term, and "open source" more broadly, that we're at the point of OpenFatigue being a real concern here.
