Web and desktop interface for the OpenCode AI coding agent. Works alongside the OpenCode TUI.
The OpenCode team is actively working on their own desktop app. I still decided to release this project as a fan-made alternative.
It was entirely built with OpenCode tool - first with the TUI version, then with the first usable version of OpenChamber, which I then used to build the rest.
The whole project was built entirely with AI coding agents under my supervision. It started as a hobby project and proof of concept that AI agents can create genuinely usable software.

Why use OpenChamber?
Cross-device continuity: Start in TUI, continue on tablet/phone, return to terminal - same session
Remote access: Use OpenCode from anywhere via browser
Familiarity: A visual alternative for developers who prefer GUI workflows
Features
Core (all app versions)
Branchable chat timeline with /undo, /redo, and one-click forks from earlier turns
Smart tool UIs for diffs, file operations, permissions, and long-running task progress
Voice mode with speech input and read-aloud responses for hands-free workflows
Multi-agent runs from one prompt with isolated worktrees for safe side-by-side comparisons

Data Directory Permission Note: The data/ directory is mounted into the container for persistent storage (config, sessions, SSH keys, workspaces). Before running, ensure the directory exists and has proper permissions:
# Create data directories with correct ownership
mkdir -p data/openchamber data/opencode/share data/opencode/config data/ssh
# Fix permissions (replace $USER with your username)
chown -R 1000:1000 data/
Without proper permissions, the container may fail to start or encounter permission denied errors when writing to these directories.
SSH/Git Authentication Note: If git pull/push fails. Run ssh -T git@github.com in terminal.
