If you've started running more than one AI coding agent at a time — one fixing a bug while another writes tests, say — you've probably hit the same wall: your terminal turns into a mess of tabs, you lose track of which agent is waiting for your input, and if your laptop sleeps or your SSH connection drops, a long-running session can just vanish. A small wave of terminal tools has shown up specifically to fix that, plus a couple of related headaches: seeing what your AI assistant is actually telling its plugins, and getting quick command help without leaving the terminal at all. Here are six worth knowing about.
Mux0 — a terminal built around running several agents
Mux0 is a terminal app made specifically for people running several AI coding agents (like Claude Code) side by side. Instead of tabbing between plain terminal windows and guessing which one needs you, it shows at a glance which agents are still working, which are stuck waiting on your input, and which just finished. It's free for both personal and commercial use, though the code is source-available rather than fully open source — you can read it, but not redistribute it.
Good for: developers who run 3+ agents regularly and want a dashboard-style overview instead of raw terminal tabs. Limits: young product, and the source-available license means no forking it into your own distributed tool.
Thel — keeping long agent sessions alive
Thel tackles a narrower but very real problem: long AI coding-agent sessions that die the moment you close your laptop lid or lose your connection. It keeps sessions alive and lets you check back in on them later, similar in spirit to tmux but purpose-built for supervising agents rather than general terminal multiplexing. Pricing isn't published yet — the site is minimal, which suggests an early-stage product.
Good for: anyone who's lost a multi-hour agent run to a dropped SSH connection. Limits: no visible pricing or roadmap yet, so treat it as an early bet rather than a settled tool.
Intent by Augment Code — multiple agents on the same codebase, without collisions
Intent by Augment Code is a workspace for running multiple AI coding agents on the same codebase at once. It uses isolated git worktrees for each agent so they don't overwrite each other's changes, plus a shared "living spec" document so the agents stay aligned on what they're actually building instead of duplicating or contradicting each other's work. It's free during the current public beta on macOS; Windows support is on a waitlist and Augment hasn't announced final pricing.
Good for: teams or solo devs who want several agents genuinely collaborating on one repo, not just running in parallel unaware of each other. Limits: macOS-only for now, beta pricing is temporary, and it ties you into Augment's own workflow.
AIOffice — a playful way to keep tabs on many agents
AIOffice takes a different approach entirely: a small pixel-art office where each AI coding assistant you're running gets its own desk. Instead of juggling four terminal tabs and trying to remember which is which, you glance at the office and see who's "at their desk" working. It's open source under the MIT license and completely free.
Good for: developers who find plain status text easy to miss and want something visual — and don't mind a bit of novelty. Limits: it's a visualization layer, not a full session manager like Mux0 or Thel, so it works best paired with something that actually keeps sessions running.
mcpsnoop — seeing what your agent tells its tools
mcpsnoop answers a different question: when an AI coding assistant's tool call goes wrong, what did it actually send to the MCP server behind the scenes? Instead of guessing, mcpsnoop shows the live traffic between your assistant and its MCP plugins, essentially a network sniffer built for AI agents. It's free and open source under the MIT license.
Good for: debugging flaky MCP tool calls when the agent's own explanation isn't enough. Limits: it's a debugging tool for people who already know what MCP traffic looks like, not a general-purpose dashboard.
Terminai — inline command help, not agent orchestration
Terminai is the odd one out on this list — it's not about running multiple agents at all. It adds a lightweight AI assistant to your existing terminal: press Ctrl+Space, describe what you want, and it suggests a command — but it always asks before actually running anything. Free and open source under the MIT license.
Good for: anyone who wants AI command help without adopting a whole new terminal or agent-management workflow. Limits: it solves a much smaller problem than the rest of this list — one suggested command at a time, not multi-agent supervision.
Side by side
| Tool | Best for | Price | Platform |
|---|---|---|---|
| Mux0 | Dashboard view of several running agents | Free (source-available) | Terminal app |
| Thel | Surviving disconnects on long agent sessions | Not published | Terminal app |
| Intent by Augment Code | Multiple agents collaborating on one repo | Free (macOS beta) | macOS (Windows waitlist) |
| AIOffice | Visual, at-a-glance agent status | Free, open source (MIT) | Desktop app |
| mcpsnoop | Debugging MCP tool-call traffic | Free, open source (MIT) | CLI |
| Terminai | Inline AI command suggestions | Free, open source (MIT) | Terminal add-on |
None of these compete head-to-head — they solve different slices of the same "I'm running more AI agents than I can watch" problem. If you just need to see several agents at once, start with Mux0 or the more visual AIOffice. If disconnects keep killing your sessions, Thel is built for exactly that. If your agents are actively stepping on each other's changes in the same repo, Intent is the one designed to prevent that. And if something's going wrong at the tool-call level, mcpsnoop will show you the raw traffic instead of leaving you to guess.
