MobSF

Overview

MobSF is a self-hosted framework for automated security analysis of mobile apps and their source code. It is best suited to developers and security teams that need mobile-focused checks they can run locally or in a CI/CD pipeline. Its broad analysis coverage is useful, but dynamic testing has a narrow Android version range.

Key features

Static analysis checks source code and binaries for security flaws and misconfigurations before execution, making it a practical first review of code or a release package. Dynamic analysis adds runtime evidence by running an app in a controlled sandbox and observing behavior, data flow, and API interactions. That combination is more useful than relying on either approach alone, though dynamic analysis is limited to rooted Android versions 4.1 through 11.0, up to API 30.

MobSF also identifies suspicious code patterns, permissions, and behaviors for malware analysis. It accepts APK, XAPK, IPA, and APPX packages, along with zipped source code, so it can cover several mobile app formats. Obfuscation does not rule out analysis, but code protection techniques can reduce its depth.

Reports include severity levels, affected files or functions, and remediation suggestions, with HTML, PDF, and JSON export options. REST APIs support CI/CD and DevSecOps workflows, with Jenkins, GitHub Actions, and GitLab CI as integration examples. This makes MobSF a natural fit for teams that want repeatable checks and actionable findings within their existing pipeline.

Installation is available through GitHub or Docker, and the framework runs on Windows, Linux, or macOS. It can also operate completely offline, a useful option for teams that need to keep analysis within a local environment.

Pricing

MobSF Community Edition costs nothing and is open source under GPL v3. It includes the self-hosted framework for source and binary analysis, with CI/CD support. There are no paid entry tiers or published seat or scan caps to weigh against a lower-cost plan; teams that need priority feature requests, live support, or onsite training can look to the enterprise support option.

Platforms

MobSF supports Android and iOS app analysis, along with Windows packages such as APPX. The framework runs on Windows, Linux, or macOS and is self-hosted; its offline capability suits environments that cannot send app material to a cloud service. Dynamic analysis is specifically constrained to rooted Android versions 4.1–11.0, up to API 30.

Who it's for

MobSF is a strong choice for mobile developers, penetration testers, and security teams that want static, dynamic, and malware-oriented checks in a self-hosted workflow. Its REST API and named CI/CD integrations make it especially relevant to teams automating security checks. It is less suitable when dynamic analysis must cover Android versions beyond API 30, or when protected apps require deeper inspection than the tool can provide.

Pros and cons

• Pros: Static and dynamic analysis plus malware detection give mobile teams several complementary ways to investigate an app.
• Pros: Reports include severity, affected code locations, and remediation suggestions, with three export formats for sharing or triage.
• Pros: Self-hosted, offline operation and REST API support suit local workflows and CI/CD automation.
• Cons: Dynamic analysis stops at rooted Android 11.0/API 30, excluding newer Android targets from that workflow.
• Cons: Obfuscation and code protection can limit analysis depth, so results may be less complete for apps using those techniques.
• Cons: Free support is limited to the Slack channel; teams needing priority requests, live support, or onsite training require enterprise support.

Alternatives

For a broader scan of source code and supply chain repositories, Semgrep Code offers a free edition covering up to 10 repositories and 10 contributors, with 60 AI credits. Teams seeking a cloud-connected software composition analysis service can consider Snyk Open Source, whose free plan covers five projects. For a free open-source static analyzer focused on Python, Pysa is the more targeted choice; for Node.js projects, NodeJsScan offers a self-hosted open-source option.

Skylos is another option, with a free local CLI and limited cloud tier. Horusec provides free open-source CLI and platform components, while Puma Scan offers a free community project as well as a paid annual license. Flawfinder is a free GPL-2.0+ open-source alternative.

Verdict

Choose MobSF if you need a free, self-hosted mobile security framework that combines static checks, sandboxed runtime analysis, reporting, and pipeline integration. Its offline operation and mobile package coverage are compelling for teams managing their own analysis environment. Look elsewhere if your dynamic testing needs Android versions newer than 11.0, or if code protection makes the available analysis too shallow for your requirements.
