Codex CLI is OpenAI's open-source coding agent in the terminal. It runs great in any shell but looks like every other terminal by default. MOLTamp is the skinnable wrapper that gives Codex a visual identity, widget framework, and community of themes.
Built to run Codex without friction
- Official Codex CLI runs untouched — MOLTamp spawns it as a child process
- Same API keys, config, and MCP servers you already use
- Skin library spans minimalist to cyberpunk — pick your aesthetic
- Widget framework lets you add music, telemetry, visualizers
- Switch between Codex, Claude Code, Gemini CLI in different tabs with different skins
Three steps. No config reshuffle.
Install MOLTamp
Download the free macOS build. Drag to Applications.
Configure Codex

What you get on top of Codex
Agent-agnostic by design
MOLTamp does not favor any agent. Codex gets exactly the same treatment as Claude Code or Gemini CLI — pick your agent, pick your skin, go.
Full skin system
Themes are JSON manifests + CSS. Everything is customizable: chrome, colors, fonts, panel shadows, window shape.
Widget library
Music player, audio visualizers, Pomodoro timer, Live2D companions, ambient scenes. Drop in what you want, ignore the rest.
MCP server support
Codex's MCP servers keep working exactly as configured. MOLTamp does not proxy or rewrite anything in your agent's I/O.
Switch agents per tab
Run Codex in one tab, Claude Code in another, Aider in a third. Each tab can have its own skin for visual separation.
Community marketplace
Browse skins and widgets built by the community. Rate, review, and publish your own.
Themes that look great with Codex
Handpicked from the community gallery — every one of them is free.
Questions Codex users ask
Does MOLTamp change how Codex CLI works?
No. Codex runs as a child process exactly as it would in any terminal. Your config, keys, and MCP servers all work unchanged.
Can I run Codex and Claude Code side by side in MOLTamp?
Yes — each tab can run a different agent. Many developers use this to compare agents on the same task or to route different work to different agents.
Does MOLTamp work with Codex's MCP servers?
Yes. MCP servers are configured at the Codex level — MOLTamp does not touch them. Whatever works in your current terminal works in MOLTamp.
Is Codex support treated as a second-class citizen?
No — MOLTamp is explicitly agent-agnostic. The skin system, widgets, and telemetry work the same across every supported agent.
