Your agents,together.

Monitter is an open-source workspace for running, watching, and coordinating AI coding agents. Bring the CLI harnesses you already use, keep every conversation in view, and run agents on this machine or another one over SSH.

Main is clean. Three UI changes are still in separate worktrees. The font work needs the remote host's font list, so I'll hand that part to Mona.

Fast-forwarded main to 161336a. The resource-modal test passes and the DraftPicker files are still uncommitted.

Font selectors now load host font families through a native list_system_fonts command. Manual entry stays as the fallback.

Uses the harnesses
you already have.

Monitter drives each CLI through its native sessions and sign-in. It never swaps in its own model API. Native adapters cover four harnesses, and the Agent Client Protocol connects the rest.

Cross-agent collaboration

Agents that hand work to each other.

Supported agents can discover peers, exchange messages, and delegate linked tasks. The receiving agent runs on its own harness and host, and its result lands back in the conversation that asked.

  • Subagents stay visible. Active and recent subagents get their own panel with a timeline and approvals.
  • Each agent keeps its own authority. A delegated task uses the receiving harness's permissions, never the sender's.

Everything in view. Nothing hidden in a terminal tab.

Panes and project workspaces

Keep conversations side by side, balance or expand the pane that needs you, and group chats by project. One project can span several agents and machines.

Full keyboard control

The searchable Controls palette reaches layouts, new chats, terminals, agent creation, and settings without the mouse.

Provider usage rings

Readable activity

Tool calls, reasoning summaries, approvals, and errors fold into each turn. Scroll back to read while new output waits for you.

Pair Android or iOS to read, reply, and stop work. Execution stays on the desktop.

Share a chat

Invite guests by approval. They join by name, and the eye shows everyone watching.

Check the branch and changes, see tracked processes, and open a terminal in the chat's working folder.

Runtime collector

A garbage disposal for idle CLI processes.

Persistent agents shouldn't mean a growing pile of idle processes. After five minutes of inactivity, Monitter retires eligible local harnesses and keeps the conversation and native session. Your next message resumes it.

  • Conservative by design. Active work, queued messages, pending approvals, and uncertain background jobs keep a runtime alive.
  • Only its own processes. The collector targets processes Monitter started. SSH runtimes are retained.
  • CPU and RAM in the sidebar. See Monitter and each harness it owns, with history and per-process detail on macOS.

Remote hosts

Your agents can live on another machine.

Configure a host, a working folder, and a harness executable, then work with that agent from the same workspace. Monitter uses your system SSH config, keys, and host-key checks, and the harness keeps the remote machine's own session and credentials.

Platform status

Built on a Mac. Open to everywhere else.

macOS is the main development platform. Windows and Linux builds have not been tried yet, so if you run either, a build report is one of the most useful contributions you can make.

Build and try it

Run it from source.

You'll need Node, Rust, and the Tauri build dependencies for your OS. On macOS that includes the Xcode command-line tools. Agents need at least one harness installed and signed in.
