Marl Code reads, edits and runs your code with you, in the terminal. It is proprietary Quavern software, distributed as a binary, with an interface in English and French.
It needs a Marl subscription on the Pro plan or above.
Installing
macOS, Linux and NetBSD:
curl -fsSL https://dl.quavern.net/MarlCode/install.sh | sh
Windows, in PowerShell:
irm https://dl.quavern.net/MarlCode/install.ps1 | iex
The installer verifies every download against the published release checksum before touching anything. Direct downloads and the checksum file are on marl.quavern.ai/code.
Signing in
marl login opens your browser; approve the request with your myQuavern account. There is no API key to copy.
If the approval comes from a network Quavern flags as higher-risk, you are asked to verify a telephone number first. An ordinary sign-in from an ordinary network is not blocked.
In scripts and CI, use marl login --with-token with an API key, then marl -p "…".

Organisation policy
With an organisation service token, Marl Code applies the workspace policy set in myQuavern: allowed tools, denied commands, forced plan mode, a turn cap. A policy only narrows; it never grants.
Crash reporting is off
Marl Code reports nothing to Quavern unless you turn it on with marl telemetry on. When enabled, it sends the version, the operating system and the stack trace of a crash — never your prompts, your code or your file paths. marl telemetry off stops it.
When Marl is in maintenance
Marl Code shows the message the Quavern team published for that maintenance instead of failing silently.
If something goes wrong
Every failure carries a code of the form CODE3-0001. Write to [email protected] with that code, the version from marl version, your operating system, and what you asked for.
