 ## Features & Capabilities

 ### 🌍 Deployment Freedom
+
 - **Remote Access**: Host CodeNomad on a powerful workstation and access it from your lightweight laptop.
 - **Code Anywhere**: Tunnel in via VPN or SSH to code securely from coffee shops or while traveling.
 - **Multi-Device**: The responsive web client works on tablets and iPads, turning any screen into a dev terminal.
 - **Always-On**: Run as a background service so your sessions are always ready when you connect.

 ### ⚡️ Workspace Power
+
 - **Multi-Instance**: Juggle multiple OpenCode sessions side-by-side with per-instance tabs.
 - **Long-Context Native**: Scroll through massive transcripts without hitches.
 - **Deep Task Awareness**: Monitor background tasks and child sessions without losing your flow.
 - **Command Palette**: A single, global palette to jump tabs, launch tools, and fire shortcuts.

 ## Prerequisites
+
 - **OpenCode**: `opencode` must be installed and configured on your system.
 - Node.js 18+ and npm (for running or building from source).
 - A workspace folder on disk you want to serve.

 ### Authentication
+
 - Default behavior: CodeNomad requires a login (username/password) and stores a session cookie in the browser.
 - `--dangerously-skip-auth` / `CODENOMAD_SKIP_AUTH=true` disables the login prompt and treats all requests as authenticated.
  Use this only when access is already protected by another layer (SSO proxy, VPN, Coder workspace auth, etc.).
  If you bind to `0.0.0.0` while skipping auth, anyone who can reach the port can access the API.

 ### Progressive Web App (PWA)
+
 When running as a server CodeNomad can also be installed as a PWA from any supported browser, giving you a native app experience just like the Electron installation but executing on the remote server instead.

VooDisss	d36e568ed0	fix: Use legacy diff algorithm for better large file performance - Set diffAlgorithm to 'legacy' for Monaco DiffEditor - Add maxComputationTime of 10s to avoid UI freeze on huge files This addresses the issue where sessions with large JSON files (50k-100k+ lines) would cause the UI to freeze. The 'legacy' algorithm is faster than 'advanced' for large files, similar to VSCode's workaround for the same issue. See: https://github.com/microsoft/vscode/issues/184037	2026-02-23 02:30:44 +02:00
