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 apps versions)
- Integrated terminal
- Git operations with identity management and AI commit message generation
- Smart tool visualization (inline diffs, file trees, results highlighting)
- Rich permission cards with syntax-highlighted operation previews
- Per-agent permission modes (ask/allow/full) per session
- Multi-agent runs from a single prompt (isolated worktrees; Web/PWA + Desktop)
- Branchable conversations: start a new session from any assistant response
- Task tracker UI with live progress and tool summaries
- Model selection UX: favorites, recents, and configurable tool output density
- UI scaling controls (font size and spacing)
- Session auto-cleanup with configurable retention
- Memory optimizations with LRU eviction
### Web / PWA
- Mobile-first UI with gestures and optimized terminal controls
- Self-serve web updates (no CLI required)
- Update and restart keeps previous server settings (port/password)
- Cloudflare Quick Tunnel support for easy remote access (`--try-cf-tunnel`)
- QR code generation for quick mobile access (`--tunnel-qr`)
- Auto-login URL with embedded password (`--tunnel-password-url`)
### Desktop (macOS)
- Native macOS menu bar integration with app actions
- First-launch directory picker to minimize permission prompts
### VS Code Extension
- Editor-integrated file picker and click-to-open from tool output
- In-extension Settings access and theme mapping
### GitHub Actions (Cloud Usage)
Run OpenChamber remotely using GitHub Actions. No local computer required.
* **Zero Setup:** Runs on GitHub's infrastructure.
* **Persistence:** Optional; enabled when `OPENCODE_SERVER_PASSWORD` is set (encrypted).
* **Remote Access:** Access via secure tunnel (Cloudflare/Ngrok).
