You can migrate an existing project from another platform directly into Base44. Base44 connects to your source and brings over not just the design and structure, but your actual data too: contacts, products, pages, and more. Pick up right where you left off, without starting from scratch. This works with both SaaS tools like Salesforce, HubSpot, Shopify, and WordPress, and vibe-coding platforms like Lovable and Bolt.new.

Base44 imports 100 items from each entity first so you can preview your app before committing. Once you’re happy with the result, you’re prompted to migrate all your data.
You can’t migrate a project if any one of its entities, or tables, holds too many items on a standard plan. The Enterprise plan supports larger projects. If your project is too large, the Choose entities to migrate panel shows “This project is too large to migrate.” To move it, talk to the Base44 sales team about the Enterprise plan.
