Which to pick
Bolt is the safer pick on every axis we score. Base44 earns its place in the index, but nothing in these four numbers argues for it over Bolt.
Bolt
Bolt builds and runs the whole project in the browser, which makes the loop between asking and seeing unusually short. It is happiest with self-contained projects where you want to poke at the files yourself, and it is candid about handing you the terminal when you need it.
Where it shines
- Install, run and edit happen in the tab, so there is no local setup at all
- Full file access the moment you want to stop prompting and start typing
- Fast to prototype something rough and iterate on it in one sitting
Base44
Base44 turns a plain description into a working application with its own database, user accounts and hosting, then lets you keep refining in conversation. Wix acquired it in 2025, which put real infrastructure behind what began as a solo project.
Where it shines
- Data and authentication are handled rather than left as an exercise
- Genuinely fast from a blank prompt to something usable
- Backed by Wix infrastructure since the 2025 acquisition
