## Key Takeaways

- **Choose MAO for explicit coordination:** connect agents, delegate work and organize parallel development through Git worktree layers.
- **Choose Yardlet for an integrated Mac workflow:** keep coding conversations, reviews and agent tools together on compatible Apple silicon hardware.
- **Choose tabsh for session visibility:** manage shells and coding agents in a browser, with a list or board showing which tasks need attention.
- **Do not confuse multiple sessions with isolated workspaces.** tabsh explicitly leaves agents in their selected checkout; separate cards do not prevent conflicting edits.
- **Budget for the underlying agents separately.** A free workbench or one-time app purchase does not replace provider subscriptions, API charges or usage limits.

## MAO vs Yardlet vs tabsh: The Quick Verdict

**MAO is the clearest fit for visual agent orchestration, Yardlet for an integrated macOS workbench, and tabsh for browser-based terminal management.** The right choice depends on where development currently gets stuck: handing work between agents, reviewing their output, or noticing that a session needs input.

| Decision factor | MAO | Yardlet | tabsh |
| --- | --- | --- | --- |
| Primary interface | Desktop canvas | Native Mac task workspace | Browser list, board and terminals |
| Published platform support | macOS, Windows, Linux | macOS 15+ on Apple silicon | macOS and Linux; no Windows build |
| Claude Code and Codex | Supported | Supported | Supported |
| Agent coordination | Connected agents exchange tasks and results | Tasks can read, message and launch other tasks | Session tracking; comparable delegation is not documented in the reviewed pages |
| Automatic checkout isolation | Git worktree layers | Not established by the reviewed overview documentation | Explicitly not provided |
| Browser interaction | Agents can control connected portals | Agent-controlled Chromium panel | Browser-hosted interface; that alone does not automate other tabs |
| Application price | $20 once after a seven-day trial | Free | Free |
| Public license status | Paid application; open-source licensing not verified | MIT | MIT |

These distinctions follow the [MAO product site](https://trymao.dev/), [Yardlet repository](https://github.com/zzunkie/yardlet) and [tabsh website](https://tabsh.cc/). Unverified functionality should be checked in the installed release rather than treated as absent. 

## MAO: Best Fit for Visible Multi-Agent Coordination

MAO places coding agents on a canvas and uses connections to define communication through its orchestration bridge. Its [orchestration guide](https://trymao.dev/multi-agent-orchestration) describes an Orchestrator that can recruit agents, connect them and distribute work.

The CLI distinguishes between waiting for a result and dispatching work asynchronously: `mao ask` waits for an answer, while `mao send` returns a task identifier that can be collected with `mao wait`. This makes handoffs more explicit than manually copying terminal output. 

**The practical advantage is an inspectable workflow.** For example, a feature can have a written acceptance checklist, an implementation task and a separate review task. The useful question is whether every handoff identifies the relevant branch, changed files, test results and remaining uncertainty.

MAO's [layer documentation](https://trymao.dev/docs/layers-git-worktrees/create-layer) adds a concrete boundary: each layer has a Git worktree and canvas state. Creating one does not automatically switch the active canvas to it. Copied nodes begin as drafts, and permission-bypass launch options are not copied. Those details matter when preparing parallel writers. 

Landing a layer checks for conflicts and uncommitted changes before bringing its branch into Ground. The layer is archived afterward by default unless retained. **This is an integration workflow, not proof that the combined application works.** Run the relevant checks against the integrated result. 

MAO also supports browser automation. Its [portal commands](https://trymao.dev/docs/portals-browser-android-ios/browser-portal-cli) can navigate, inspect, screenshot and interact with an existing connected browser portal. Each operation checks the connection; the commands do not create a browser themselves. 

**Recommended use:** a feature with separable implementation tasks and an explicit integration owner. For a small copy edit or a single straightforward bug, the extra coordination may add little value.

## Yardlet: Best Fit for an Integrated Mac Workbench

Yardlet is written in Swift and SwiftUI and starts existing agent CLIs with their own accounts. Its repository describes native session storage, an adjacent diff and PR workflow, account-limit visibility, connectors and a built-in browser. The published requirement is **macOS 15 or later on Apple silicon**. 

Its task tools go beyond displaying several conversations. `read_task`, `send_message_to_task`, `create_task`, `run_agent` and `wait_tasks` support coordination between sessions. Scheduled tasks run while Yardlet is open, and cross-project messaging or task creation requires approval.

The website also describes forwarding a user's original approval wording with its timestamp and checking that the quoted wording exists in the originating conversation. This improves traceability, but checking that words were written does not establish that a proposed action still satisfies every condition attached to them. 

**The strongest reason to choose Yardlet is a shorter review path.** A useful trial is to ask one agent to implement a bounded change, have another inspect the diff, and measure how easily the developer can find the affected files and failed checks.

Do not equate task separation with repository isolation. The overview material reviewed here does not establish automatic per-task worktrees. Check each task's working directory and branch before allowing concurrent edits.

## tabsh: Best Fit for Browser-Based Session Management

tabsh combines a Rust daemon with a browser interface. The daemon runs local shells; cards organize agent sessions across projects. Its repository documents both terminal and chat views, plus restoration of tabs, folders and scrollback. 

**Its value is making unattended sessions easier to find.** A developer managing several repositories may benefit more from seeing the one session waiting for input than from adding another orchestration layer.

Automatic status updates need setup. The [tabsh documentation](https://tabsh.cc/docs/) explains that `tabsh setup` prints instructions for the agent to follow, including backing up and changing configuration. Provider integrations differ: the documented Codex path uses a `notify` hook and lacks an event for the moment a prompt is submitted.

The completion state also matters: a finished agent turn can become `needs_input`; marking the overall task `completed` is a separate action. **A card marked complete is an agent-reported status, not a CI result.** 

tabsh explicitly does not create worktree isolation. Two writers in the same checkout can interfere with each other. Use one writer per checkout, manually assign separate worktrees, or reserve additional sessions for read-only investigation. 

## The Most Important Technical Difference: Sessions vs Worktrees

A session is a conversation and its running agent. A worktree is a separate working directory attached to a Git repository. Two conversations can still read and modify exactly the same files.

[Git's worktree documentation](https://git-scm.com/docs/git-worktree) explains how one repository can have multiple working trees with separate checkout state. For a clean repository with an existing `main` branch, the following example creates two new branches and working directories:

```bash
git status --short
git worktree add -b agent/frontend ../app-frontend main
git worktree add -b agent/backend ../app-backend main
git worktree list
```

Commit or otherwise preserve existing work first, and replace `main` if the repository uses another base branch. Assign each writer the appropriate directory. These are Git commands, not a claim that tabsh or Yardlet automatically manages those worktrees. 

**Engineering implication:** separate checkouts reduce filesystem interference, but do not isolate every dependency. Parallel development still needs coordination around:

- **Interfaces:** agree on request fields, response shapes and error behavior before splitting frontend and backend work.
- **Runtime resources:** give development servers separate ports and avoid unintended use of a shared test database.
- **Integration:** retest after combining branches; individually passing changes can conflict semantically.
- **Permissions:** a worktree is not an operating-system sandbox. An agent's actual tool permissions determine what else it can access.

For an API change, a useful division is one writer implementing the endpoint and one reviewer checking the contract. Adding a second writer before the contract is stable can increase rework.

## Pricing: Compare the App Fee With the Whole Workflow

[MAO's published pricing](https://trymao.dev/) is $20 once, following a seven-day trial. The trial covers one workspace with one project. The license adds unlimited workspaces and projects, cross-canvas connections, remote workspaces and saved arrangements. It applies to one computer at a time and permits moving it to another up to three times a year. 

Yardlet and tabsh publish MIT licenses and are free to use. Their application pricing should not be interpreted as free access to every underlying coding model. 

For evaluation, track **cost per accepted change**: app costs, provider usage and human review time divided by changes that actually meet the acceptance criteria. A workflow that generates more patches but requires longer inspection may deliver less value.

Multiple agents also repeat some work. Each may read the same files, reconstruct context or rerun checks. Start with an author and reviewer; add parallel writers only when the tasks are sufficiently independent.

## Privacy and Remote Access: Follow the Actual Data Path

**A local interface does not imply local model inference.** There are distinct paths to inspect: application metadata, data sent by coding agents to model providers, and data accessed through connectors.

MAO states that agents contact their providers directly, added keys use the operating system's credential store, and diagnostics are disabled by default. It also documents license and update requests. Local project storage should therefore not be described as an entirely offline product. 

[Yardlet's privacy policy](https://yardlet.app/privacy.html) states that it has no analytics and stores connector credentials in macOS Keychain. It explicitly explains that prompts and material an agent reads, including connector results, are sent to the selected AI provider under the user's account. Provider settings and terms remain relevant. 

tabsh documents a loopback daemon and optional Tailscale access. It warns against exposing the shell-serving HTTP port directly to a network. Use the documented private-access configuration rather than assuming that a browser interface is safe to publish publicly. 

For sensitive projects, enable only the connectors needed for the task and review the underlying agent's permissions. A coordination app cannot make an overly broad command permission harmless.

## A Practical Evaluation Before Committing

Use the same small feature in separate disposable branches. Keep the model, acceptance criteria and repository starting point consistent. This is a proposed evaluation method, not a published benchmark.

| Check | What to measure | Why it matters |
| --- | --- | --- |
| Setup | Minutes until the existing agent completes a first task | Reveals installation and authentication friction |
| Attention | Time to notice and answer a blocked request | Measures whether the interface reduces waiting |
| Review | Time to find the diff, tests and unresolved issues | Measures human supervision effort |
| Integration | Conflicts and regressions after combining work | Tests the usefulness of workspace boundaries |
| Recovery | What survives closing the interface and reopening it | Separates session recovery from continuous execution |
| Outcome | Accepted change, provider usage and human minutes | Connects activity to delivered value |

Record failures as well as successes. For example, a resumed transcript does not necessarily mean a process ran while the machine slept. A visible task plan does not establish that its checks were executed.

Use an explicit task brief to make comparisons fair:

```text
Goal: Add a loading state to the search form.
Acceptance: Prevent duplicate submissions and preserve keyboard access.
Scope: Modify the search UI and its relevant tests only.
Review: Inspect the diff and report bugs without editing files.
Completion: List changed files, checks run and unresolved issues.
Stop: Ask before changing the API contract or adding dependencies.
```

## Installation and Release Checks

For Yardlet, first confirm the Mac meets its requirements and that an agent CLI is installed and signed in. Its documented Homebrew command is:

```bash
brew install --cask zzunkie/tap/yardlet
```

The repository warns that `main` can describe functionality ahead of the latest release. Compare documentation with the installed version before relying on a particular feature. 

For tabsh, its repository documents this Homebrew setup:

```bash
brew install blaise1030/tap/tabsh
tabsh
```

After confirming it works, stop that foreground instance before switching to the documented login service:

```bash
brew services start tabsh
```

Then follow the [agent-hook setup guide](https://tabsh.cc/docs/) for automatic task status updates. Merely opening a terminal card does not configure those integrations. 

For MAO, use its [official download page](https://trymao.dev/) and begin with a small canvas. Verify a single handoff and a single layer integration before expanding the team.

## Frequently Asked Questions

**Can Claude Code and Codex work together?**

Yes. MAO documents connected-agent task exchange, and Yardlet exposes cross-agent task tools. tabsh can organize both CLIs, but session management alone does not establish automatic delegation between them. 

**Which option should Windows developers evaluate first?**

MAO is the only one of these three advertising a Windows desktop build. Yardlet requires a compatible Mac, and tabsh explicitly lists no Windows build. Browser availability does not establish daemon compatibility. 

**Does browser-based mean cloud-hosted development?**

No. tabsh's browser UI connects to a daemon on the development machine. Separately, any cloud-backed coding agent it launches can still communicate with its model provider. 

**Will using more agents make development faster?**

That depends on the task. Parallel work is useful when dependencies are clear and review remains manageable. For tightly coupled edits, sequential implementation with a separate reviewer can be easier to control. The reviewed documentation does not establish a comparable measured speed advantage among these three products.

## Conclusion

**Select the tool around the bottleneck you can measure.** Evaluate MAO when handoffs and parallel branches need structure, Yardlet when a compatible Mac needs a consolidated development workspace, and tabsh when scattered sessions make it difficult to notice what needs attention.

Start with one bounded feature and an author-reviewer pair. Keep the tool that reduces waiting and review effort while producing an acceptable change. Expand the workflow only after that small trial succeeds.
