* feat: add /undo, /redo, /timeline slash commands and fork button
- Add /undo command to revert to previous user message
- Add /redo command to redo previously undone messages
- Add /timeline command to show conversation history
- Add fork button on user messages (hover) to create new session
- Add TimelineDialog component for navigating conversation history
- Show undo/redo/timeline in autocomplete when session exists
- Fix fork to use SDK session.fork API
- Silent no-op behavior for undo/redo when no messages (matches OpenCode CLI)
* fix: correct fork session endpoint and session switching
- Add hybrid SDK approach using v1 for existing methods and v2 for fork only
- v2 SDK has correct endpoint /session/{sessionID}/fork instead of broken /session/{id}/fork
- Fix forkFromMessage to use setCurrentSession instead of direct set
- Ensures both useSessionStore and useSessionManagementStore are consistent
- Fixes issue where forked sessions appeared empty until sending a new message
* fix: use direct fetch for fork to avoid v2 SDK build errors
- Remove v2 SDK imports and hybrid SDK approach
- Use direct fetch() call to /api/session/{sessionID}/fork endpoint
- Avoids type conflicts between v1 and v2 SDK
- Bypasses broken v1 SDK fork endpoint (wrong path parameter)
- All codebase now uses v1 SDK consistently
* fix: use jsonc-parser for config file parsing
- Replace strip-json-comments + JSON.parse with jsonc-parser
- Handles comments, trailing commas, and unquoted keys
- Matches OpenCode CLI config parsing behavior
- Fixes SyntaxError when reading global opencode.json config
* feat: improve timeline dialog with loading state and search
- Add loading spinner on fork button during operation (~30s on big sessions)
- Refresh session list after fork so new session appears in sidebar immediately
- Add search bar to filter messages by prompt text content
- Show 'No messages found' when search has no results
- Disable fork button while forking to prevent duplicate operations
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 apps versions)
Integrated terminal
Git operations with identity management and AI commit message generation
