OneDev workspaces are browser-based (in-browser terminals and coding agents). There is no native mobile app, and no first-class integration with Remodex or similar phone clients.

Practical options:

1. Use Remodex on a host you control (best fit for Remodex)
   Remodex is built to pair with a Codex bridge on your Mac (or another machine). Keep the repo there, push/pull to OneDev as usual, and drive Codex from your phone via Remodex. OneDev stays your git/CI hub; Remodex does not need the OneDev workspace web UI.

2. Run Remodex inside a OneDev workspace (DIY / unsupported)
   Create a workspace from a Codex template, install and start the Remodex bridge in a workspace terminal (npm i -g remodex, then remodex up). Remodex reaches the phone through its own relay (or Tailscale / a self-hosted relay), so you generally should not rely on OneDev's exposed HTTP port mappings for pairing. Caveats: Remodex is mainly documented for Mac; launchd background persistence will not apply in a container; Codex must be authenticated inside the workspace; and this is not an officially supported setup.

3. Phone browser
   Opening the workspace page in a mobile browser remains the supported path, though we understand it may not match a native client.

If you want first-class mobile / Remodex support as a product feature, say so and we can treat this as a feature request.

The second approach actually works very well. Thx!
