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

• Provider-aware tunnel access model with Cloudflare quick, managed-remote, and managed-local modes

• 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

Custom Themes

• Use it from anywhere - Cloudflare tunnel with QR code onboarding. Scan, connect, code from your couch.
• Branchable chat timeline - Undo, redo, fork from any turn. Explore different approaches without losing your place.
• GitHub-native workflows - Start sessions from issues and PRs with context already attached. Review checks, merge - all in-app.
• Project Actions - Run dev servers, configure SSH port forwarding, open remote URLs locally. Your project commands, one click away.
• Connect to remote machines - Desktop app connects to remote OpenChamber instances over SSH, with dedicated lifecycle and UX flows.

Connect to an existing OpenCode server:

OPENCODE_PORT=4096 OPENCODE_SKIP_START=true openchamber
OPENCODE_HOST=https://myhost:4096 OPENCODE_SKIP_START=true openchamber

Bind managed OpenCode server to all interfaces (use only on trusted networks):

OPENCHAMBER_OPENCODE_HOSTNAME=0.0.0.0 openchamber --port 3000

</details> <details> <summary>systemd service (VPN / LAN access)</summary>

Run OpenChamber and OpenCode as separate persistent services — useful when you want to access your dev machine over a VPN (e.g. Tailscale) or LAN without a Cloudflare tunnel.

How it works:

• OpenCode runs as its own service, binding only to localhost.
• OpenChamber connects to it via OPENCODE_HOST and --host 0.0.0.0 makes it reachable on your VPN I
