Frequently Asked Questions

What is the difference between GenMB and OpenAI Codex?▼
GenMB is an AI app builder that generates complete applications from prompts with one-click deployment. OpenAI Codex is an autonomous coding agent that works on existing GitHub repos in sandboxed cloud environments. GenMB creates apps from scratch; Codex modifies existing codebases.
Can OpenAI Codex generate and deploy a full app like GenMB?▼
No. Codex works with existing codebases, writing code and creating PRs. It does not generate complete applications, provision databases, or deploy. GenMB handles the full lifecycle from generation to live deployment with custom domains.
Can I run multiple tasks with GenMB like Codex?▼
GenMB focuses on interactive, real-time app building with Prompt Queue (queue up to 10 prompts). Codex can run multiple independent tasks in parallel cloud sandboxes. Different approaches — interactive vs batch.
