Builder Product Updates

Connect Fusion to Publish with the Builder CMS MCP server to access your content directly with Fusion’s AI. Use prompts to search, browse, create, and update content, models, and assets. All without leaving your workflow.

Now Fusion Pro customers can password protect the builder.my preview links Fusion generates from a project/branch.

Keep your code fully local with client-controlled encryption and end-to-end encrypted chats, ensuring Builder never stores or sees your full codebase. This is designed for enterprises that require maximum data privacy.

Install the Builder.io app for your MacOs or Windows computer. Easily launch Builder as a desktop app, better connect to your local code, and access enhanced enterprise security features. Download Builder Desktop

Share your invite link with a friend! When they sign up and upgrade to a Fusion Pro plan, you will both instantly earn 200 bonus agent credits. Try it now at https://builder.io/app/projects

Bonus credits don't count against your monthly AI limits and are used first when running AI tasks.

Now you can switch between Sonnet, GPT-5 and GPT-5 Mini while using Fusion. Switching to a lower cost model uses a fraction of the credits, so you can create and iterate up to 10x more with GPT-5 Mini.

Using the Notion MCP in Fusion, you can now copy a URL from Notion, paste it into Fusion to give the AI context of everything in the doc, no more manual copy / paste workflows so you can go from a Notion doc to a built-out app in minutes.
