An opcode (Claudia) alternative with Codex and Gemini CLI
As of October 28, 2026
opcode calls itself a GUI app and toolkit for Claude Code: a desktop app for Claude Code’s projects and sessions, custom agents, usage and MCP servers, called Claudia until it took the name opcode in August 2025. Moontors is an agentic development environment (ADE), a Claude Code GUI that runs Codex and Gemini CLI too, side by side, on macOS, Windows and Linux.
At a glance
Section titled “At a glance”| opcode | Moontors | |
|---|---|---|
| Agents | Claude Code | Claude Code, Codex and Gemini CLI |
| Platforms | Builds for macOS and Linux; Windows built from its source | macOS 13+, Windows 10+ (x64), Linux (x86-64); an app for Android and iPhone, on Google Play and the App Store; the Windows and Linux builds aren't signed yet, and Windows asks before the first open; on Windows 11, Smart App Control, when it's on, blocks unsigned apps, Moontors among them; early preview (0.x) (Known limits) |
| Needs | Claude Code, installed | Each agent's own sign-in; no Moontors account needed (Signing in) |
| Licence | AGPL-3.0, open source | Free, closed source |
| Data | No data collected or tracked, and all of it kept on your machine | No Moontors account needed, and no Moontors server can read your sessions. Moontors itself sends no telemetry; each agent's own usage data follows that agent's settings |
What each has that the other doesn’t
Section titled “What each has that the other doesn’t”opcode:
- open source, under the AGPL-3.0 licence;
- custom agents, each with its own system prompt and its own file and network permissions, run in the background;
- a usage dashboard of Claude Code’s cost and tokens by model, project and day, with charts and an export;
- checkpoints on a branching timeline, each restored with one click, with the diff between any two;
- a scan for every CLAUDE.md in your projects, each opened in its editor with a live preview;
- MCP servers added and tested from its window, or imported from Claude Desktop.
Moontors:
- Codex and Gemini CLI beside Claude Code;
- a release for Windows, as for macOS and Linux, where opcode’s latest release has none;
- a git worktree for a session, made, used and cleaned up for you, when you want one (Worktrees);
- an app for Android and iPhone, on Google Play and the App Store, that follows and answers your computer's own sessions over a link encrypted end to end, which no Moontors server can read.
Where opcode (Claudia) is the better fit
Section titled “Where opcode (Claudia) is the better fit”- You want an open-source app.
- You use Claude Code alone, and want agents of your own, each with its own prompt and permissions.
- You want charts of what Claude Code costs you, by model, project and day.
- You want every CLAUDE.md across your projects found for you, and MCP servers added from the app.
