In their own words
Flawfinder
Flawfinder is a free tool for finding possible security weaknesses in C and C++ source code. It compares source text with a built-in database of functions associated with security problems, generally disregarding comments and strings except for Flawfinder directives. Findings are ordered by risk, which depends on the function and its parameter values; the tool may reduce some false positives when it identifies a construct as not risky. Reports can be generated as text, HTML, CSV, or SARIF. The --patch option narrows findings to changed lines in a unified diff, with a one-line margin. Installation is documented through pip, source downloads, and distribution packages, and the tool requires Python 2.7 or Python 3. The project says it works on Unix-like systems, including GNU/Linux, and on Windows with Cygwin; direct Windows use has also been reported to work. Flawfinder is released under GPL-2.0+. It does not perform control-flow or data-flow analysis, so its output is an aid to review rather than a substitute for security knowledge or human judgment.
MobSF
MobSF is a mobile application security research platform for penetration testing, malware analysis and privacy analysis. Its Static Analyzer supports APK, IPA, APPX and source code; the Dynamic Analyzer works with Android and iOS applications and includes interactive instrumented testing, runtime data analysis and network traffic analysis. REST APIs and CLI tools connect MobSF to DevSecOps and CI/CD pipelines, and pull request scans are supported. The project provides a Docker image and quick-start commands for local use, and links to MobSF Static Analyzer Online. The framework is open source under GPL-3.0, with a free MobSF plan at free. Paid options are Professional at $2,999.99 a year, Enterprise at $6,999.99 a year, and Training at $10,999.99 a year. They list support, training or consultation services. Limited free help is available through Slack; GitHub issues are for bug reports and feature requests. The project links to a security policy and describes MobSF as made in India.
