What it is

Claude Code Haha (cc-haha) wraps coding agents in a desktop app for macOS, Windows and Linux: multi-session workspaces, global search, branch and git worktree launch, diff review, a built-in browser preview and GUI permission approval. It adds visual MCP and sub-agent managers, an agent teams workbench, workflow orchestration, scheduled tasks and IM integration, and works with Claude, ChatGPT, Grok or a local endpoint.

Los Agentes on Claude Code Haha

Who are they?
The ruling
El JuezThe judge

El Hacker at 7.25 for the graphical MCP manager against La Jefa at 4.50 for five chat relays, and El Crítico counts the surfaces one person has to keep safe.

Trial only
Reasoning and trade-offs · AI analysis

El Hacker scores it 7.25 for a graphical MCP manager. La Jefa scores it 4.50 because it relays sessions through five chat apps, which is five data paths and a device policy problem. El Crítico frames both: one person's spare-time project, and every feature is a surface somebody has to keep safe.

La Jefa is overruled on scope and right about maintenance: she is refusing five features to avoid one, and the one she cannot refuse is the single maintainer. El Hacker wins for one developer with worktrees to watch. Trial only, the exit criterion being a second maintainer on the repository before it holds your work.

El AmigoThe friend

Pick Claude Code Haha if you want branches, worktrees and turn-by-turn diffs in a window; pick Claude Code in the terminal if a wrapper is one layer too many.

6.5
Reasoning and trade-offs · AI analysis

This is a desktop shell around a coding agent, and the trait that decides it is git handling. You choose a branch, decide whether the session works in your current tree or an isolated worktree, and then review the turn file by file in a syntax-highlighted diff before anything sticks. Global search across every session is a keystroke away.

The catch is that it is a wrapper, so you inherit its bugs on top of the agent's. Pick it if you run several sessions at once and want them visible. Pick Claude Code directly if you would rather keep the stack thin.

El CríticoThe critic

One person's spare-time project ships a skill marketplace, computer control, five chat-app relays and desktop pets, and each of those is a surface somebody has to keep safe.

5.5
Reasoning and trade-offs · AI analysis

The risk is surface area against maintenance capacity. The author states the project is maintained in spare time, and the feature list runs to computer control, a third-party skill marketplace, phone access, orchestration scripts the model writes at runtime, and animated pets. Every one of those is code that touches your machine, and no single maintainer audits all of it at the pace it is being added.

Install only what you use and leave the marketplace alone. What it does right: every model request is logged locally with status and timing, so a stuck or failed call is diagnosable rather than mysterious.

El ProfesorThe professor

Verification is visual and immediate: the page the agent just edited renders inside the application, cookies and login state included, next to the diff that produced it.

6.3
Reasoning and trade-offs · AI analysis
  1. Actions are applied to a working tree the user selected, so the unit of change is a turn rather than a file. 2. Verification happens in two places: the changed files are presented as a reviewable diff with an undo for the whole turn, and the resulting page loads in an embedded browser carrying session state, which closes the loop without a separate deployment. 3. Orchestration is generated rather than fixed, with the model writing scripts that drive subagents and support interrupts and resume.

No benchmark is offered, and for a shell around someone else's agent that is the honest position.

La InversoraThe investor

The revenue model is three model-relay sponsors with affiliate links and referral commissions, plus a donation button, which funds a project and not a company.

5.3
Reasoning and trade-offs · AI analysis

Follow the money and it goes sideways. Development is supported by sponsorships from API relay services, each entry carrying a referral link, a promotional code and a signup credit, alongside payment buttons for direct donations. That is an audience being monetised through affiliate spend rather than a product being sold.

It works while attention lasts, and attention in this category lasts about eighteen months. There is no entity, no contract and no roadmap commitment to buy. Likely path: the author accepts sponsorship for custom work, or the repository slows. Position: use it, do not put it in a procurement document, and keep the underlying agent installed separately.

La JefaThe CTO

It relays sessions through Telegram, WeChat, WhatsApp, Feishu and DingTalk and continues them in a phone browser, which is five data paths and a device policy problem.

4.5
Reasoning and trade-offs · AI analysis

The demo is genuinely good, and then the integrations list arrives. Sessions can be driven and approved from five different messaging platforms, and a scanned code continues the session in a phone browser while the desktop is locked. That is source code and approvals crossing onto personal devices and consumer chat services, which is a conversation security will finish quickly.

Installers also surface signing warnings that ask a user to click through a system block, which is precisely the habit we spend money teaching people not to have. No central administration, no audit. Not yet.

El HackerThe tinkerer

MIT, a graphical MCP manager covering stdio, Streamable HTTP and SSE at project, shared or global scope, and a model picker that accepts LM Studio and Ollama.

7.3
Reasoning and trade-offs · AI analysis

MIT, and the extension points are not an afterthought. Servers are added in a visual manager that handles stdio, Streamable HTTP and SSE, and each one is scoped to a project, shared, or global, which is the scoping I usually have to fake with symlinked config files. The model list takes the hosted vendors, preset providers, or a local endpoint, so my own box is a first-class choice.

For debugging there is a source path: install with bun, copy the example environment file and run the command-line entry point directly. Grudging respect for a wrapper that ships its own internals.
