ZAP (Zed Attack Proxy) Pricing 2026: Plans, Pros & Cons

Overview

ZAP, the Zed Attack Proxy, is a free and open-source web application security scanner. The project describes itself as the world’s most widely used web app scanner and as a community-based GitHub Top 1000 project that anyone can contribute to; it states that ZAP is an independent open-source project^[27].

ZAP works as an intercepting proxy between a browser and a web application, recording traffic for manual testing, and as an automated scanner that spiders an application and runs passive and active vulnerability checks. It can be scripted and run headless in CI pipelines, and it is often the first web scanner that developers and students learn, supported by the project’s quick-start guide and introductory video^[27].

ZAP has no licence cost. Its trade-offs are those of most community tools: no vendor support contract, fewer enterprise features such as portfolio dashboards, and more manual configuration for authenticated applications than commercial DAST products such as Invicti or Burp Suite DAST.
