Coder Xum
coder · Agent
Xum is a coding agent multiplexer for running and managing a suite of agents from one interface. Each agent works in an isolated workspace, which can be your project directory, a git worktree on your machine, or a remote server over SSH, and a central view shows git divergence. It has its own agent loop with Plan and Exec modes, supports several models including local ones through Ollama, and has a VS Code extension for jumping into workspaces.

Why it's useful
You can keep a group of coding agents working in separate workspaces and see their status, costs and git changes in one place.
What you could do with it
- Start several agents in separate git worktrees and watch git divergence and possible conflicts across them.
- Run an agent on a remote server over SSH while you follow its status from the sidebar.
- Point an agent at a local model through Ollama, or at a wider range of models through OpenRouter.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Data handling disclosed
- finding
- no statement of what it reads, writes or sends (README.md)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.31.0, the file with digest sha512-Z2w3VC6Vo/KEkC6Xr5lU6zAd6BUzN++Rw1l51HMlM/e0lKKgp4sckKvqJ1DMtxZJ1Z2UaqM1y/53zkiXPfeQIw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y -p @coder/xum@0.31.0 muxPinned to 0.31.0, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
