Desktop and web interface for OpenCode AI agent
Last verified:
What is Openchamber?
OpenChamber is a development environment for engineering with AI agents, serving as a visual control room around OpenCode (the AI coding agent that runs in your terminal). It gives you a screen to watch and steer AI coding work instead of living on the command line, enabling branching sessions, reviewing diffs, managing terminals, watching tool progress, running project actions, and keeping the full board visible while the agent works.
The tool works across desktop (macOS app), browser (web app/PWA), phone, and VS Code extension, letting you move between platforms without losing the thread. Key features include branchable chat timelines with undo/redo and one-click forks, smart tool UIs for diffs and file operations, live streaming updates, Mermaid diagram rendering, Agent Manager for parallel multi-model runs, Git/GitHub workflows for committing and opening PRs, Project Actions for dev servers and SSH forwarding, and UI password protection for remote access.
OpenChamber is designed for developers and DevOps engineers who want to orchestrate AI coding agents with a natural, logical interface. It's ideal for those who need less tab-hopping, want to review diffs visually, need to code from their phone via tunnels, or want agent-native workflows inside VS Code. The tool is open source and free to use.
Openchamber pricing
Pricing model: Freemium
OpenChamber is completely free to use. The tool itself has no paid plans or subscription tiers. It is open source with code available on GitHub. Users only pay for the underlying AI models they connect through OpenCode (such as OpenAI, Anthropic, or other provider costs), not for OpenChamber itself.

Frequently asked questions about Openchamber
Is OpenChamber open source?
Yes, OpenChamber is open source, and the code is available on GitHub. The privacy model is visible in the code instead of hidden behind policy language.
What does OpenChamber run on?
OpenChamber runs on the OpenCode SDK, which was chosen for the best open-source agent experience available. You must install OpenCode first using the command: curl -fsSL https://opencode.ai/install | bash
Is OpenChamber free?
Yes, OpenChamber itself is free to use. There are no paid plans or subscription tiers for the tool.
Can I use OpenChamber remotely?
Yes, you can open it remotely through the browser UI, use tunnels when needed, and protect access with a UI password. You can also use tunnels and scan a QR code to access it from your phone.
What are the ways to install OpenChamber?
There are three ways to run OpenChamber: desktop app for macOS, web app hosted by the CLI (which you can install as a PWA on phone/tablet), and VS Code extension from the Marketplace.
What platforms does OpenChamber support?
OpenChamber works across desktop (macOS app), browser (web app with PWA support), phone and tablet (via browser with phone-friendly controls), and VS Code (extension in the sidebar).
What is OpenChamber used for?
OpenChamber is for AI coding tasks that benefit from a control room: branching sessions, reviewing diffs, managing terminals, watching tool progress, running project actions, and keeping the full board visible while the agent works.
How do I protect my OpenChamber instance?
Browser access can be gated with a UI password, and tunnel links can be rotated or revoked when they should no longer work. OpenChamber does not collect project names, paths, prompts, code, diffs, or session content.
What is the fastest way to get started?
The fastest path is: 1) Install OpenCode, 2) Install the OpenChamber CLI, 3) Run openchamber --ui-password be-creative-here, 4) Open the URL printed (usually http://localhost:3000), 5) For phone access, start a tunnel and scan the QR code.
Which app should I use for my workflow?
Use desktop for day-to-day work on macOS, use web for remote access and reviewing from your phone, and use VS Code for sessions right next to your code. Each platform has different strengths for different use cases.
