MobSF

MobSF is a mobile application security research framework for penetration testing, malware analysis and privacy analysis. It suits teams assessing mobile apps across source code and binaries.

Overview

MobSF is a focused choice for Android and iOS security work, not a general-purpose code security platform. The free, GPL-3.0 framework can run locally, making it a practical fit for teams comfortable managing their own analysis environment.

Key features

The Static Analyzer covers APK, IPA and APPX files alongside source code, so teams can assess different mobile app inputs in one framework. The Dynamic Analyzer adds interactive instrumented testing for Android and iOS, including runtime data and network traffic analysis. That pairing makes MobSF more useful for mobile investigations where observed app behavior matters as well as code; its focus is mobile applications rather than security analysis across every software category.

REST APIs and CLI tools connect MobSF to DevSecOps and CI/CD pipelines, and the project supports pull request scans. A Docker image and quick-start commands offer a route to local deployment; the project also links to MobSF Static Analyzer Online at mobsf.live. The repository links to a security policy.

Slack is the channel for questions, help and discussion, while GitHub issues are for bugs and feature requests. Free Slack support is limited, so teams needing priority responses or live troubleshooting should weigh the paid packages.

Pricing

MobSF costs nothing and provides the GPL-3.0 open-source framework. It is the clear starting point for individuals and teams able to run the tool and rely on limited community help.

Professional costs $2,999.99 a year, billed $ 2999.99 / year. It adds live support and troubleshooting, priority support by email or Slack, an e-learning course for 5 accounts, 1 minor feature request and priority bug fixes. This fits a small team that wants responsive help without moving to the larger Enterprise training allowance.

Enterprise costs $6,999.99 a year, billed $ 6999.99 / year. It includes the same live and priority support, an e-learning course for 15 accounts, 2 major feature requests and priority bug fixes. The higher cost is aimed at organizations that need broader training access and more substantial feature requests.

Training costs $10,999.99 a year. It includes onsite or online live training, CTF challenges, CI/CD setup assistance, an e-learning course for 50 accounts and expert email consultation. Choose it for structured instruction and pipeline setup; it is difficult to justify if all that is needed is the analysis framework itself.

Platforms

MobSF supports API, Linux, macOS, self-hosted, web and Windows platforms. Its Docker image and local quick-start route make self-hosting a concrete option for teams that want to operate the framework themselves.

Who it's for

MobSF is best for mobile security researchers and development teams that need static and dynamic analysis across Android and iOS apps, plus pipeline integration.

Pros and cons

• Pros: Static analysis covers source code and APK, IPA and APPX binaries, while dynamic analysis covers Android and iOS behavior.
• Pros: REST APIs, CLI tools and pull request scans support CI/CD workflows.
• Pros: The GPL-3.0 framework is free, with Docker and quick-start commands for local use.
• Cons: Free support is limited to Slack; bug reports and feature requests use GitHub issues, not a priority support channel.
• Cons: Paid plans are annual commitments, starting at $2,999.99 a year for professional support and training.

Alternatives

For a broader shortlist, see SAST Tools. Snyk Open Source is worth considering if a freemium option and a free plan capped at 5 projects for Snyk Open Source (SCA) better match the need. Semgrep Code is another free-plan option, with its Free Edition capped at 10 repositories and 10 contributors. NaiveSystems Analyze offers a freemium alternative with some open-source components, including an on-premises analysis runner.

NodeJsScan, Flawfinder, Bandit, gosec and Security Code Scan are also alternatives to consider.

Verdict

Choose MobSF if you need mobile app security analysis spanning source code, binaries and runtime behavior, with CI/CD integration and a free open-source framework. Look elsewhere if your work is not centered on mobile apps, or if you need live support and training without committing to an annual paid plan.
