Everything your AI needs to
build your next idea.
+ many moreOur mission is democratizing building on the web. We want to make it easy and fun for humans to express ideas and unleash their creativity by building apps, websites, blogs, stores and more.
Spacefast is not an AI builder. Connect your favorite AI to it, and your agent will get the skills, tools and the infrastructure it needs to build better and faster.
Each thing you make gets its own Space. Create a share link or make it public before sending it to anyone. No account needed to get started.
Spaces are private by default. Invite a few people, share a private link, or make it public whenever you are ready.
Who can open this space
Try things without worrying. Each change to your Space saves a version, so you can always go back to one you liked more.
Turn on comments to hear what people think, right where it applies. Take care of them yourself, or let your AI handle it.
Every Space comes with a database, so your app can keep sign-ups, scores, or orders. Nothing to set up first.
Let the people who use your app upload photos, documents, and videos. They are saved right in your Space, with nothing extra to set up.
Views, visitors, and your top pages, counted for you. There is no tracker to add.
Agent-native publishing
Tell Claude, ChatGPT, or any other AI to use Spacefast and you get a link back right in the chat. Keep making changes whenever you like, and anyone with the share link sees them.
