Terrarium vs Claude Artifact Runner
A native macOS app and a CLI tool — two different approaches to the same goal: getting Claude-generated React components running locally.
TL;DR
Terrarium is a visual, drag-and-drop macOS app built for rapid previewing with Claude Code integration. Claude Artifact Runner is a CLI tool that can also build deployable HTML, scaffold full projects, and run in Docker — better for pipelines and production workflows.

Where Terrarium wins
Visual, GUI-first experience
Drag a .tsx file onto the dock icon or double-click it in Finder. No terminal needed. Terrarium feels like a native Mac app because it is one — built with Tauri for a small footprint and fast startup. For developers who prefer visual workflows, this is a significant ergonomic advantage over typing CLI commands.
Claude Code integration
The two-terminal workflow — Terrarium watching a file while Claude Code edits it — creates a tight feedback loop. Describe a change to Claude, see it render immediately. Claude Artifact Runner lacks this integration; it's designed more for one-shot runs than iterative development.
Multi-window previews
Open several components simultaneously in separate windows. Compare variants, keep a reference visible, or preview parent and child components at the same time.
Lower Node.js requirement
Terrarium requires Node.js 18+, while Claude Artifact Runner needs Node.js 20+. If you're on an older Node version, Terrarium is more accommodating.
Where Claude Artifact Runner wins
Build and deploy
Claude Artifact Runner can output a single HTML file or a full multi-file build ready for static hosting. This makes it useful beyond previewing — you can go from Claude artifact to deployed prototype in one command. Terrarium is strictly a preview tool with no build output.
Project scaffolding
The create mode generates a complete editable project with TypeScript, Tailwind, shadcn/ui, and full Vite tooling. Ideal for when a prototype outgrows its single-file origins and needs proper project structure.
Docker and CI/CD
Run artifacts without local Node.js via Docker. Integrate into CI/CD pipelines for automated builds. Terrarium is a desktop app with no Docker or automation story.
Cross-platform and multi-page apps
Runs on any OS with Node.js. Supports file-based routing to combine multiple artifacts into multi-page applications. Also bundles Three.js for 3D artifacts, which Terrarium doesn't support.
Workflow comparison
Terrarium workflow
- Generate component in Claude
- Save as .tsx file (or let Claude Code write it)
- Drag file to Terrarium (or double-click)
- Edit in Claude Code — preview updates live
- Iterate until satisfied
Best for: rapid iteration and visual feedback
Artifact Runner workflow
- Generate component in Claude
- Save as .tsx file
- Run
npx run-claude-artifact my-app.tsx - Preview in browser at localhost:5173
- Build with
npx run-claude-artifact build my-app.tsx - Deploy the output
Best for: preview-to-deploy pipelines
