Pick B4X if…

B4X suits developers building across mobile, desktop, server, and IoT targets, especially those able to reuse code among B4A, B4J, and B4i projects. B4i users should account for its stated Apple account, device, and IDE requirements.

Pick GitHub CodeQL if…

CodeQL is for developers and security teams who want query-based code analysis in an IDE, CLI, or CI workflow. Its availability depends on supported languages, operating systems, and repository eligibility.
