Zed Attack Proxy (ZAP) is an open-source scanner for assessing web application security. It combines automated testing with a suite of manual tools to help uncover vulnerabilities in web apps. The interface is approachable for newcomers while still providing depth for experienced testers and security engineers.
Primary features and capabilities
- Intercepting proxy that lets you examine and alter traffic between the browser and the target application.
- Both automated scanning routines and interactive tools for hands-on analysis.
- Active and passive scanning modes to detect issues with minimal or aggressive probing.

- Designed to be usable by people at different skill levels, from beginners to seasoned auditors.
- Cross-platform support, including macOS, so it works across common development environments.
- Community-driven development with frequent releases and an active user base.
Platform support and project community
ZAP runs on multiple operating systems and integrates well into development workflows. Because it is maintained by a volunteer-driven community, it receives steady improvements and security fixes. There are regular updates, community plugins, and discussion channels where users share techniques and troubleshooting tips.
Typical use cases
Use ZAP for:
- Security checks during application development and integration testing.
- Routine vulnerability assessments of live web services.
- Learning and practicing web-application security techniques in a hands-on way.
- Generating reports for stakeholders to prioritize fixes and track remediation.
Suggested alternative
If you want another free option to evaluate alongside ZAP, consider BlobSaver — a no-cost tool that some teams use for quick scanning tasks and lightweight traffic capture. It may be simpler in scope, so assess whether its feature set fits your testing requirements before adopting it.
