CST VerdictBased on our analysis of core features, integrations, here is our conclusion:
Mobile security engineers who need to inspect API calls in Android apps during dynamic testing will find PAPIMonitor's Frida-based approach faster than manual instrumentation or proxy interception. The tool is free and lightweight enough to run on modest hardware, making it accessible for small security teams or researchers without budget for commercial DAST platforms. Skip this if your team lacks Python fluency or needs to test iOS apps; PAPIMonitor is Android-specific and requires hands-on scripting to define which APIs to monitor.
Development teams that want attack surface visibility without vendor lock-in should start with Secure Decisions ASTAM, a government-funded toolset that maps hidden endpoints and optional parameters across your entire application stack at no cost. The DHS backing and native integrations with Burp Suite and OWASP ZAP mean you're not subsidizing a vendor's R&D; you're getting legitimate AppSec infrastructure. Skip this if your org needs a single commercial vendor to call for support and SLAs, or if you're already committed to a monolithic DAST platform with proprietary workflows.
