Choose Base44 if you want one managed place to build, publish and run an app; choose Cursor if you want AI inside a codebase and are ready to own the technical stack. Base44 (from $16/month) gives a non-technical builder a database, authentication, functions, integrations and hosting by default. Cursor (from $20/month) is a developer-first AI coding environment: it can work across a repository and accelerate implementation, but your team still chooses and operates the framework, backend, deployment and production workflow.
The old “closed app builder versus real code editor” shorthand is now inaccurate. Base44 documents a full code tab, two-way GitHub sync on Builder and higher, local development, a CLI and SDK, and an eject path. That makes the tools complementary as well as competitive: a team can build in Base44 and work on the synced code in Cursor. The honest boundary is the managed backend and data. Ejecting creates a separate project and copies schemas, but not production data, so a full move away still needs a migration plan.
