Murmell vs Gemini Code Assist
Gemini Code Assist is agent mode inside VS Code and IntelliJ, with a plan you approve before it starts and a human in the loop while it runs. Murmell is a canvas where several agents work on a shared cloud directory and you watch the terminals rather than approving steps.
The real difference
Gemini Code Assist is built around consent. Google describes agent mode as multiple file edits with full project context and a human in the loop, and for a complex task it proposes a plan you can question and adjust before anything begins. That is a serious answer to the trust problem, and it costs a round trip at the start of every task.
Murmell answers the same problem by showing rather than asking. The terminal is visible while the agent works, so you interrupt when it goes wrong instead of approving before it starts.
The second difference is number. One editor holds one agent mode session, and Google documents nothing about several of them in one directory. Murmell exists for that case: an agent claims the paths it is about to write, the server refuses everybody else, and five can work in the same checkout without a merge at the end.
Where Gemini Code Assist wins
Context length and price, and both matter. It sits in the editor you already have, it works with the Google account your company already pays for, and the free tier is generous enough to be somebody’s whole setup.
The GitHub reviewer is also genuinely useful and has no equivalent here. Murmell pushes work to a repository and leaves review where your review already is.
Which to pick
Gemini Code Assist when you write the code and want a good agent beside you inside the editor. Murmell when the agents write it, several at a time, and the room matters. What a cloud agent actually does.
Side by side
| Gemini Code Assist | Murmell | |
|---|---|---|
| Where a second agent works | Your editor, in an agent mode session, on a plan you approve first | One shared directory, after it claims the paths it is about to touch |
| Who can watch it happen | Whoever is at the editor, and reviewers on the pull request afterwards | Anybody with the link, live, with a name on every cursor |
| Where the work lands | Your working tree, and a pull request Gemini can review on GitHub | A private repository for the project, pushed as the agents go |
Straight answers
Can Gemini Code Assist run several agents in parallel?
Google documents agent mode as a session in your editor: multiple file edits, full project context, built-in tools, MCP, and a human in the loop, with a plan you approve for complex tasks. It documents no parallel agents sharing one directory, which is the thing Murmell is built around.
What does the GitHub side do?
It reviews. Google documents a Gemini-powered agent on GitHub that summarises pull requests and comments on them, and that you can address with /gemini in the thread. That is review of code somebody already wrote, not a second agent writing.
Which should I pick?
Gemini Code Assist when you are the one writing and want a strong agent in the editor you already use, with approval before it acts. Murmell when the writing is done by several agents at once and the useful thing is watching them rather than approving each plan.
