If you've started running more than one AI coding agent at a time — a Claude Code session fixing a bug while another writes tests, plus a Codex session refactoring somewhere else — you've probably hit the same wall: plain terminal tabs don't tell you which one actually needs your attention right now. MulmoTerminal and Neoswarm both exist to fix that, and both are free and open source, but they take almost opposite approaches to the interface — one is a browser-based visual grid, the other a keyboard-driven terminal dashboard styled after Neovim.
Quick comparison
| MulmoTerminal | Neoswarm | |
|---|---|---|
| Interface | Browser-based grid of terminal tiles | Neovim-style TUI, keyboard-driven |
| Session backend | Real PTY terminals via tmux | Persistent workspaces, agents keep running after you close the terminal |
| Agent providers | Focused on Claude Code / Codex | Claude, OpenAI, Google, OpenRouter, Ollama |
| Isolation | Git worktree per session, one-click PR | Not a stated focus |
| Notifications | Mobile push when a session needs input | Not a stated focus |
| Extensibility | Not a stated focus | TypeScript plugin system |
| License / price | MIT, free, no commercial tier | MIT, free, open source |
MulmoTerminal — a color-coded visual grid in your browser
The short version: MulmoTerminal gives you a grid of real terminal panes, each one running a Claude Code or Codex session, color-coded so you can tell at a glance which ones are working, which are done, and which are stuck waiting on you. Under the hood, sessions run as real PTY terminals through tmux, so closing the browser tab doesn't kill the work — and each session gets its own git worktree, with a one-click flow to open a pull request once the agent is done.
Who it's for: developers running several Claude Code or Codex sessions in parallel who want a visual, at-a-glance view of session state, plus a fast path from "agent finished" to "PR opened."
Pricing: free and open source under MIT, with no commercial tier.
Honest limits: it only pays off once you're genuinely running several sessions at once — for a single agent it's overkill — and it needs tmux and node-pty set up correctly to work. It's also a young project with a smaller community than an established terminal multiplexer.
Neoswarm — a Neovim-style dashboard for any agent provider
The short version: Neoswarm is a terminal dashboard built for people who already live in Vim — fully keyboard-navigable, customizable, and not tied to one AI provider. It supports Claude, OpenAI, Google, OpenRouter, and Ollama, and workspaces persist so agents keep running even after you close the terminal.
Who it's for: terminal-native developers comfortable with Vim-style navigation who want to mix and match model providers rather than being locked into one, and who'd rather extend the tool themselves through its TypeScript plugin system than wait for built-in features.
Pricing: free and open source under MIT.
Honest limits: it's terminal-only with a real learning curve if you're not used to Vim-style keybindings, it's a niche tool compared to a GUI-based agent manager, and — like MulmoTerminal — it's a recent project without a long track record yet.
Pick MulmoTerminal if…
…you want a visual, color-coded overview you can glance at from a browser tab, you're specifically running Claude Code or Codex, and you'd value one-click PR creation plus mobile push notifications when a session needs you.
Pick Neoswarm if…
…you're already comfortable in a Neovim-style keyboard workflow, you want to run agents from more than one provider side by side, and you'd rather have a plugin system to extend the tool yourself than a fixed feature set.
Both tools solve the same real problem — plain terminal tabs don't scale once you're running several AI coding agents at once — and neither costs anything to try. If your workflow is browser-based and centered on Claude Code or Codex, MulmoTerminal's visual grid and one-click PR flow will likely feel more immediate. If you're a terminal purist who wants provider flexibility and room to extend the tool yourself, Neoswarm's Vim-style dashboard is the better fit.
