Explained

Murmell explained, one page per idea

Murmell runs Claude Code, Codex and the rest on machines we operate, and puts several of them in one project directory where an agent claims a file before it writes to it. These pages take that apart one piece at a time.

What is Murmell? Several coding agents in one repository

The short answer: what Murmell is, what you see, and what happens to the code.

Claude Code in the browser

Claude Code in a browser tab, with nothing installed and the session outliving the tab.

Run Claude Code in the cloud

How Claude Code runs on a machine we operate instead of on your laptop.

Multiple AI agents on one repo

The file reservation board, and what two agents did with it when we watched.

Multiplayer coding with AI agents

The two halves of multiplayer on Murmell: many agents, and many people watching them.

A cloud sandbox for AI agents

What the machine running agent code holds, and which secrets never reach it.

Figma for developers: a multiplayer canvas for code

What the Figma analogy gets right about Murmell, and where it overreaches.

Set against other tools

Most tools that run coding agents in parallel give each one its own copy of your files. Murmell does not, and the comparison pages go through ten of them one at a time, naming what each does and where the two shapes part.
