Everything to build and share a website, in one place.

Multi-file editor with live preview, Emmet, a terminal, GitHub push and import. HTML or React, no build step.

An AI agent that plans, edits your files, checks its work and lets you undo every change. Gemini included; bring Claude or OpenAI keys if you like.

Store images, videos and documents with folders, favorites and a trash. Every file gets a fast public URL.

Send files with an expiring link, optional password and download stats.

A link-in-bio page with themes, social icons and click analytics.

Publish to a store of community websites, games and tools — and get discovered.

Branded short links with QR codes, expiry and per-country stats.

Your code is yours: export a ZIP or push to GitHub any time.

Spark Pages runs on shared free tiers, so everyone gets a daily budget. Add your own AI key for unlimited agent use.
