Choose Base44 when...
Your first goal is to prototype a small web app without choosing hosting and backend services separately. Check monthly AI and integration credits, supported functions, and domain conditions.
Choose Codex when...
You need flexibility in a codebase, want to maintain an existing app, or have technical help available for deployment and ongoing updates. Codex does not remove your responsibility for hosting, testing, security and support.
Do not overlook total cost
Include the AI subscription, hosting, database, domains, maintenance time, and any app-store requirements. A low entry price does not mean that a production app has no additional cost.
Which approach fits your project?
Base44 may be the simpler place to test an integrated web-app idea. Codex may suit teams that want to work directly with code and external development infrastructure. Match the choice to your project, not a marketing headline.
