How we chose these Codev alternatives
We looked for open-source tools that build web apps with AI assistance like Codev. We verified Reflex's license, recent activity, stars, and deployment options in its repository. See our methodology for the full criteria.
Important: scope
Reflex is a framework first and an AI builder second, and it is aimed at Python teams. It is not a no-code tool for people who do not write code.
License details
Reflex is Apache-2.0.
Maintenance status
Reflex had commits within days of this update.
Why look for a Codev alternative?
Codev is a proprietary AI app builder, so your generated apps and prompts depend on its platform. An open-source framework keeps code in your repository and runs on any host, but the AI builder around it is a separate product.
reflex.dev
Reflex combines an Apache-2.0 full-stack Python framework with Reflex Build, an AI-assisted browser workflow for prompts, live previews, code editing, testing, integrations, Git, and deployment. Generated applications remain standard editable Reflex source code.
