A control room for terminals you already use
Munder Difflin does not invent another coding model. It wraps agent command-line tools already installed on your computer, including Claude Code, Codex, Copilot CLI, Antigravity, Grok, Kimi, Qwen, OpenCode, Crush, and pi. Every worker is a real process in a pseudo-terminal. The Electron app renders those sessions as characters in a small office, while an orchestrator called Michael accepts the main request and routes work across the floor.
The joke would wear thin if the office were only animation. Underneath it is a serious attempt to solve multi-agent coordination. Each worker gets an identity, working directory, mailbox, memory, and optional git worktree. A shared hive stores tasks, a blackboard, an append-only log, and messages as local files. The app exposes live terminals, agent state, tasks, costs, git history, branch comparisons, and a Monaco editor.
That visibility is the project's best idea. With several coding agents active, the difficult questions are mundane: who owns which branch, which terminal is waiting, whether a message arrived, where a result lives, and what the group has spent. Munder Difflin gives those questions one home.
Coordination is designed, not merely claimed
Agents do not all write to one git index. The hive uses a single committer for its coordination repository, while optional worktrees isolate code changes. Workers write outgoing messages to their own directories, and the router moves them into recipients' inboxes. This file-based design is easier to inspect than a hidden orchestration database.
The terminal delivery rules show similar care. Automatic writers share one queue, which waits for an agent to be idle and tries to detect whether the human has a draft or picker open. Messages are acknowledged only after the text and submit writes succeed. The documentation also describes the imperfection: prompt state is inferred from keystrokes and the rendered terminal, and after a long expiry a queued message can join text still sitting at the prompt.
Human gates cover spending, destructive operations, and scope changes. A circuit breaker can steer, constrain, or stop an agent that appears to loop or burn its budget. This machinery has evolved through reported failures. A closed issue documented twelve false circuit-breaker alarms during idle and compaction activity, and release 0.3.9 removed a usage-limit guard that could hold agents indefinitely. Test the controls rather than treating their labels as guarantees.
Local-first does not mean fully isolated
The security policy says the app spawns local processes and accesses registered directories. Renderer code lacks direct Node access, filesystem and git calls are path-validated in the main process, and the local hive uses a Unix socket rather than a public listener. Those are sensible Electron boundaries. They do not turn the coding agents into sandboxed programs. A permitted agent CLI can still act inside its working directory with the skills and MCP servers you grant it.
Use a clean worktree, limit credentials, review imported hires, and begin with narrow permissions. The app includes a write-only secret broker and asks for approval around critical actions, but an autonomous local process remains powerful. Slack and webhook triggers increase the need to define who can start work and which repositories can be touched.
Privacy is comparatively clear. Official builds send a small allowlisted set of anonymous PostHog events covering launches, agent engines, selected feature use, and a coarse session-duration bucket. The contract excludes prompts, transcripts, paths, repository names, accounts, and keys. Users can opt out during onboarding, in settings, or through DO_NOT_TRACK; source builds have no analytics key. Provider traffic is separate, so each CLI's data policy still applies.
Installation is an ecosystem decision
Packaged builds exist for macOS, Windows, and x86 Linux. The macOS release is signed, while Windows is not and can trigger SmartScreen. Linux users must mark the AppImage executable. The application then needs at least one supported agent CLI and its subscription or API credentials. Voice control adds a separate OpenAI Realtime key. Local engines can use Ollama, LM Studio, or vLLM.
Source installation is ordinary Electron development with one complication: node-pty has a native addon, so Node 18+, npm, and a platform C/C++ toolchain are required. Windows users with code and CLI state inside WSL2 should wait; an open August 16 request explains that path resolution, command selection, working directories, and hive sockets do not cross that boundary correctly.
The project is moving fast enough that release history matters. Version 0.3.7 fixed an updater that had silently failed in packaged builds since 0.3.4, leaving 0.3.5 and 0.3.6 users needing one manual upgrade. Current open reports include onboarding failing to create the suggested agent folder and garbled interim text. These are prototype problems in core paths.
Health, licensing, and the buying decision
The repository was pushed on August 15, 2026, version 0.4.3 was released two days earlier, and new issues and pull requests were active on August 16. GitHub lists 24 open issues and pull requests combined. The cadence shows committed maintenance, but the security policy supports only main, and the README explicitly calls the product a working prototype.
Code is MIT-licensed, but the bundled LimeZu tiles, maps, and recolored character sheets are restricted to non-commercial use. That distinction explains GitHub's inability to assign one simple repository license and matters to anyone redistributing a branded build. Replace the assets or obtain the appropriate license before commercializing it.
For developers already living in several agent terminals, Munder Difflin can make the work legible and enjoyable. Its architecture is more convincing than its clone-working-forever pitch. Install it for supervised experiments, keep backups, and let it earn broader authority over time.
