Web and desktop interface for the [OpenCode](https://opencode.ai) 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
- Git workflows in-app: identities, commits, PR creation, checks, and merge actions
- GitHub-native workflows: start sessions from issues and pull requests with context already attached
- Plan/Build mode with a dedicated plan view for drafting and iterating implementation steps
- Inline comment drafts on diffs, files, and plans that can be sent back to the agent
- Context visibility tools (token/cost breakdowns, raw message inspection, and activity summaries)
- Integrated terminal with per-directory sessions and stable performance on heavy output
- Built-in skills catalog and local skill management for reusable automation workflows
### Web / PWA
- Cloudflare Quick Tunnel for instant remote access (`--try-cf-tunnel`)
- One-scan onboarding with tunnel QR + password URL helpers
- Mobile-first experience: optimized chat controls, keyboard-safe layouts, and attachment-friendly UI
- Background notifications plus reliable cross-tab session activity tracking
- Built-in self-update + restart flow that keeps your server settings intact
### Desktop (macOS)
- Native macOS menu integration with polished app actions and deep-link handling
- Multi-window support for parallel project/session workflows
- "Open In" shortcuts for Finder, Terminal, and your preferred editor
- Fast switching between local and remote instances
- Workspace-first startup flow with directory picker and steadier window restore behavior
### VS Code Extension
- Editor-native workflow: open files directly from tool output and keep sessions beside your code
- Agent Manager for parallel multi-model runs from a single prompt
- Right-click actions to add context, explain selections, and improve code in-place
- In-extension settings, responsive layout, and theme mapping that matches your editor
- Hardened runtime lifecycle and health checks for faster startup and fewer stuck reconnect states
