ArcadeLab vs Replit for publishing AI-generated apps — which fits?
💡
Quick answer
Replit is a full vibe-coding IDE plus hosting. ArcadeLab is paste-and-publish for single-file HTML output. They're different shapes, not competitors — use Replit (or Cursor, Bolt, v0, etc.) to build, then paste at arcadelab.ai/publish when you have a finished single-file thing you want to share permanently.
A lot of vibe coders ask whether ArcadeLab competes with Replit. It doesn't — not really. The two fit at different points in the workflow.
What Replit does well
- Full vibe-coding IDE with AI agent built in ("Agent")
- Multi-file projects, package management, environment variables
- Backend code (Node, Python, Go, etc.) with persistent compute
- Built-in databases (Replit DB)
- Live collaboration on code
- One-click deploy to a Replit URL
Replit shines when you're iterating on a complex project, want live AI help while coding, or need a backend. The Replit URL is fine for sharing — but it's a Replit-runtime URL, which means the project depends on Replit staying up, configured, and not sleeping.
What ArcadeLab does well
- Paste-and-publish — no IDE, no account creation, no project setup
- Permanent URL that doesn't depend on any runtime sleeping
- Embed-friendly (separate origin, sandbox-correct iframe permissions)
- Zero friction for the recipient — they click the URL and the thing runs
- Auto-injects common libraries (Phaser, p5, Three, D3, GSAP, Tone, Pixi, Matter, React)
- Open source (MIT)
ArcadeLab is the right shape when the work is finished (or finished-enough) and the goal is durable sharing.
The combined workflow
- Vibe-code your thing in Replit, Cursor, Bolt, v0, ChatGPT, Claude — whatever fits
- Once it's a stable single-file HTML version, copy the whole file
- Add an ARCADELAB header (see how to share an AI-made thing)
- Paste at arcadelab.ai/publish
- Share the permanent URL

| Account required | Yes | No |
| Multi-file projects | Yes | No (single HTML) |
| Backend code | Yes | No (sandbox) |
| Persistent URL | Yes (active deployments) | Yes (permanent) |
