Instead of OWASP Amass
OWASP Amass alternatives
OWASP Amass is a free, open-source framework for mapping attack surfaces and discovering external assets. Its collection engine uses OSINT and active reconnaissance across API, certificate, DNS, routing, scraping, web archive, and WHOIS sources. The asset database stores, manages, and retrieves findings for long-term tracking, while the Open Asset Model describes internet-exposed assets, properties, and relationships. It also supports Docker, Docker Compose, Homebrew, source installation, and a first engine REST API version. Information security professionals can run it on Linux, macOS, Windows, or a self-hosted setup.

An alternative may fit better when the goal is software composition analysis, artifact management, Android accessibility checking, dependency remediation, container development, or code-focused vulnerability analysis. Amass requires Go, network connectivity, DNS resolution, and basic reconnaissance knowledge, and its project pages identify no security certifications or compliance attestations. Compare whether you need external-asset mapping or a different workflow, such as pull-request checks, license governance, CI/CD integrations, package storage, mobile testing, container tools, or usage-based code analysis. Also weigh deployment preferences, supported ecosystems, collaboration needs, and whether a free, freemium, or paid model fits.
