Key differences

JetBrains GUI that drives Claude Code, Codex, Grok, Kimi, OpenCode, PI, OMP and the DeepSeek Harness from one chat panel

  • Runs local. Free and open source under MIT; you bring the subscription or provider key for whichever CLI engine you point it at
  • Runs multiple agents. Listed for 165 of 194 tools in this category.
  • Keep in mind: The plugin itself is a front end; command execution and file editing happen in the CLI engine it launches.

“Session history has search, favourites and export, so you can now bookmark your favourite conversation with a robot.”

What it is

CC GUI is an MIT-licensed JetBrains plugin that puts a single chat panel in front of eight terminal coding agents: Claude Code, OpenAI Codex, and in beta Grok CLI, Kimi CLI, OpenCode, PI CLI, OMP CLI and the DeepSeek Harness. It adds @file references, image input, conversation rewind, a built-in agent system for automating complex tasks, a skills slash-command system with commands such as /init and /review, MCP server support, permission management, a diff viewer, file navigation and session history with search, favourites and export. Its listing documents its network behaviour in unusual detail: requests go direct to the official Anthropic or OpenAI API unless the user configures a proxy endpoint, the UI labels a proxied route before it is used, and no credential source is read without an explicit confirmation dialog.

Los Agentes on CC GUI

Who are they?
The ruling
El JuezThe judge

El Crítico and El Profesor split over the same disclosure: he reads the honesty as evidence of care, El Crítico reads what it is honest about as the problem.

Adopt
Reasoning and trade-offs · AI analysis

El Profesor gives it the highest mark on the panel for telling you exactly where your credentials go and what it does before it goes there. El Crítico does not argue with that and points at what sits underneath: a front end is worth whatever the engine behind it is worth, and most of those engines are marked beta.

El Profesor wins for the reader who is already committed to one engine, and El Crítico is overruled for that reader only, because his risk lives entirely in the seven he would not have selected. Adopt, if you drive a single stable engine and leave the beta list alone.

El AmigoThe friend

Pick this if you live in a JetBrains IDE and want the Claude Code panel without a second window; pick Swttch if you only ever use one engine and want a thinner wrapper.

7.3
Reasoning and trade-offs · AI analysis

The deciding trait is that it does not make you choose an engine on day one. The panel takes @file references, an image, and a conversation you can rewind when a turn goes sideways, and the diff viewer means you approve changes where you already read code. If you have been alt-tabbing to a terminal and losing your place, this is the fix.

The catch is that a wrapper inherits everything, including the rough edges of whichever tool it launched. Pick it for the JetBrains habit. Pick a terminal directly when you want fewer layers.

El CríticoThe critic

Six of the eight engines are labelled beta, and a wrapper cannot be more stable than the CLI it launches. Every upstream release is a release you did not schedule.

6.3
Reasoning and trade-offs · AI analysis

The structural problem is that the contract is a command line. Grok CLI, Kimi CLI, OpenCode, PI CLI, OMP CLI and the DeepSeek Harness are carried in beta, and each one ships on its own schedule with its own flags and its own output format. A rename upstream is a broken panel here, and nothing in the design pins a version or degrades gracefully when the shape changes.

What it does right is scope the promise. Claude Code and Codex are the two that are not marked beta, and those are the two the plugin was built around.

El ProfesorThe professor

The listing documents its own network path: requests go direct to the official API unless a proxy is set, the route is labelled first, and no credential is read without a dialog.

7.5
Reasoning and trade-offs · AI analysis
  1. Publishing the data path is the rarest thing in this catalogue. Most listings describe features and leave the reader to infer where the request went; this one states the destination, states the exception, and states that the exception is shown in the interface before it takes effect. 2. Requiring an explicit dialog before reading a credential source turns an implicit capability into an observed event.

  2. None of it is verified by a third party, and disclosure is not proof. It is, however, a falsifiable claim, which is more than an unfalsifiable one.

La InversoraThe investor

5,809 stars in under a year, MIT, no meter and no seat, published by CodeMoss AI. The asset is marketplace attention, and attention is convertible if the vendor wants it to be.

7.3
Reasoning and trade-offs · AI analysis

Star counts usually tell you nothing, and this one tells you something: a plugin created in November collected five thousand of them, which is demand for a shape nobody else filled. The company giving it away has other products, so this is a funnel rather than a hobby, and funnels are maintained as long as the thing they feed is worth feeding.

Moat: none in the code, real in the listing position. Likely path: a paid tier appears above the free plugin, or the engine vendors ship their own panels. Position: use it now, expect a commercial layer later.

La JefaThe CTO

The plugin is free for sixty seats and the invoice sits somewhere else entirely, in sixty separate subscriptions to whichever engine each of them decided to point it at.

5.3
Reasoning and trade-offs · AI analysis

What this costs is not what it charges. Zero per seat, installed from a marketplace my desktop policy already allows, and then every engineer authenticates a different vendor account with a different rate and a different retention policy, which is sixty procurement questions arriving one at a time.

There is no administrative console, no single sign-on and no central record of which model saw which repository. Approved with conditions: one engine chosen centrally, keys issued by us, and the permission management screen configured before rollout rather than after.

El HackerThe tinkerer

MIT with a gradlew buildPlugin target, so the fork path is a clone away, and MCP servers attach to the panel rather than to whichever CLI happens to be running.

8.0
Reasoning and trade-offs · AI analysis

Building it from source is documented alongside the marketplace install, which tells me the author expects people to compile it, and that changes the relationship. The permission management layer is mine to configure rather than a vendor default I have to accept, and skills arrive as slash commands I can add to.

The weak spot is that model choice is not really mine here: it belongs to whichever CLI I launched, so my key lives one layer down and nothing local is reachable through this panel. Good wrapper, borrowed freedom.
