Overview

100mini is a free instant HTML hosting service built for AI-generated code. It lets you paste raw HTML/CSS/JS or upload .html/.zip files and publish them as a live, shareable link in about 30 seconds, with no signup, no registration, and no server setup. It is especially useful for Claude artifacts, ChatGPT-generated HTML, interactive UI mockups, mini games, learning pages, and single-file web prototypes. Anonymous uploads are temporary and auto-destroy after 7 days. Logging in unlocks permanent storage, title/category/tags, Learning Square sharing, and link management. A Chrome extension and an agent skill (100mini-skill) make it easier to publish directly from your browser or AI agent workflow.

Key Features

• No-signup instant publishing: paste code or upload .html/.zip and get a live URL quickly.
• AI and Claude artifact friendly: turn LLM-generated HTML, CSS, and JS into a shareable webpage.
• Anonymous and logged-in modes: anonymous pages auto-destroy after 7 days; login enables permanent storage.
• Metadata and discovery: logged-in users can add title, category, and tags, and share to the Learning Square.
