Mjolnir by Brokk

The session
control plane for coding agents.

Run long-lived agent sessions across local worktrees, containers, SSH hosts, and EC2 instances. Prompts queue durably, sessions checkpoint and resume, and one dashboard tracks sessions, quotas, and credentials.

HARNESSES / PICK ONE PER SESSIONFIVE SUPPORTED

HARNESSthe coding agent that owns the session's turns

Every target runs any of the five. The dashboard and session workflow stay consistent; isolation, approvals, resources, and credentials follow the selected target and profile.

One operating plane

Keep every coding session working when you walk away.

Mjolnir runs many Codex, Claude Code, Kimi Code, Grok Build, and DeepSeek Harness sessions at once. Prompts queue on the target, sessions survive a closed terminal, and one local daemon coordinates their state, capacity, credentials, and recovery.

01 / SESSION

The harness owns the turn

Pick one profile per session. Its native model, modes, tools, and transcript stay available through ACP.

session://durable

02 / TARGET

Choose the execution boundary

Use an existing local or SSH worktree when you need host access, or contain unrestricted work in a container or disposable EC2 instance.

target://selected

03 / CONTROL

You keep the whole fleet in view

Read live work, queue prompts, watch quota and host capacity, and resume from a verified checkpoint.

control://local

The current surface

Sessions, conversation, targets, and quota on one screen.

The terminal opens on the session that spoke most recently. Every support pane stays visible, resizes independently, and shares the same daemon-owned state with the authenticated web viewer and desktop app.

A frame rendered by Mjolnir itself. The documentation capture is regenerated from the production Ratatui renderer as the interface changes.

Why Mjolnir

Built for more than one agent in one terminal.

The control plane becomes useful when sessions outlive terminals, accounts have different quota, or work needs to move between machines without turning every target into a pet server.

01 / QUEUE

Durable sessions

Queued prompts keep their order on the target and continue while every control surface is detached.

02 / EXECUTE

Local and remote targets

Run locally, in Podman or Docker, over SSH, with Apple container, or on an EC2 instance.

03 / CAPACITY

Profiles and quota

Keep several accounts per harness and see their usable capacity in one consistent view.

04 / REMOTE

Web and desktop

Open the same daemon-owned sessions in a browser, on a phone over Tailscale, or in the native shell.

05 / RECOVER

Verified checkpoints

Stop only after byte-for-byte verification, then resume into a freshly provisioned target.

06 / AUTOMATE

Agent-operable checks

Use machine-readable doctor output and self-contained setup instructions to converge a host.

Converge before launch

Let the checks tell you when a target is ready.

Setup discovers local harness homes and runtimes. Doctor reports every prerequisite with a concrete remediation; its smoke mode proves configured runtimes can actually start and clean up their test workloads.

First session

Go from install to a detached agent.

Follow the quickstart through discovery, target checks, profile login, session creation, prompt delivery, and a clean detach. Then use the reference sections to grow beyond the generated configuration.
