Base44 is a conversation-driven application platform, operated by Wix, that positions itself as a vibe coding environment for apps, sites and agents. The starting point is a description; the result is a published application with the required infrastructure already provisioned.
The managed backend uses TypeScript serverless functions, workflows, automations and OAuth connectors, with custom integrations described through OpenAPI. The database is non-relational and compatible with MongoDB operators, with row-level and field-level security and real-time subscriptions. Authentication covers email and password, social providers and SSO with a custom identity provider.
Publishing uses built-in hosting with automatic HTTPS and custom domains. A GitHub integration makes the repository the source of truth, with branches and pull requests, and the command line lets you eject the front-end code and backend schemas.
Two limitations are stated in the documentation: published sites are single-page applications with static export and no server rendering, and the published mobile app runs the application inside a native web view.
