The short version

  • Each has a real cost: Burp Suite the automated vulnerability scanner is Professional only, at $499; the free Community edition is manual tools; OWASP ZAP authenticated scanning of modern single-page applications is the hard part and ZAP makes you build it by hand: session handling, token refresh and login scripts are configured per application, and a misconfigured session means the scanner logs itself out and reports a clean result for pages it never reached.
  • They diverge on capability: Burp Suite covers Web vulnerability scanner, OWASP ZAP covers Intercepting proxy.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Burp Suite

  • Automated scanning for web vulnerabilities on the Professional editionnot OWASP ZAP
  • Extending testing with community-built BApp extensionsnot OWASP ZAP
  • Enterprise-wide dynamic scanning through Burp DASTnot OWASP ZAP

OWASP ZAP

  • Adding a baseline security scan to every application's pipeline where per-target commercial licensing would limit coverage to a handfulnot Burp Suite
  • Manual penetration testing that needs an intercepting proxy, request replay and fuzzing without a paid licence per testernot Burp Suite
  • Teaching developers what an attack against their own endpoint looks like, using a tool they can install themselvesnot Burp Suite
  • Pre-release regression scanning of an internal application that would never justify a commercial DAST subscriptionnot Burp Suite

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Burp Suite

  • The automated vulnerability scanner is Professional only, at $499; the free Community edition is manual tools
  • BApp Store extensions require the Professional edition
  • DAST and the agentic testing product are separate enterprise offerings with no published price
  • Professional is licensed per user per year rather than perpetually

OWASP ZAP

  • Authenticated scanning of modern single-page applications is the hard part and ZAP makes you build it by hand: session handling, token refresh and login scripts are configured per application, and a misconfigured session means the scanner logs itself out and reports a clean result for pages it never reached.
  • There is no support contract in the product, so when a scan breaks the day before a release the escalation path is a GitHub issue and a community chat, which is not an answer that satisfies a delivery manager or an auditor who wants a named responsible party.
  • Active scanning sends genuine attack traffic, so it can create records, trigger emails, exhaust rate limits or destabilise a fragile environment, and pointing it at production without prior agreement produces an incident rather than a test result.
  • Output needs triage: passive rules generate large volumes of low-severity informational findings about headers and cookie flags that bury the few results that matter, and a team without someone tuning the rule set stops reading the report within a few sprints.
  • As a dynamic scanner it can only test what it can reach, so authorisation flaws between accounts, business logic abuse and anything behind an undiscovered endpoint go unreported, and a passing ZAP scan is evidence of nothing more than the absence of the classes of bug it looks for.

Answered from the vendors’ own pages

Burp Suite: Does Burp Suite offer a free version?

Yes, Burp Suite Community Edition is available free and supports manual testing. The page does not provide specific details on additional paid editions or their pricing.

Source
OWASP ZAP: Is it still called OWASP ZAP?

The project left OWASP in August 2024 and is now governed by the Software Security Project, with core development sponsored by Checkmarx. The tool is now just ZAP, though most existing documentation, courses and search results still use the OWASP name.

Burp Suite: What features are available in the free edition?

Burp Suite Community Edition supports manual security testing, though specific feature limitations compared to paid editions are not detailed on this page. Visit individual product pages for detailed tier comparisons.

Source
OWASP ZAP: Is it free for commercial use?

Yes. It is Apache 2.0 licensed, with no per-application, per-scan or per-user cost, and it can be used and modified commercially without a licence agreement.

Burp Suite: Are paid versions of Burp Suite available?

Yes, PortSwigger offers Burp Suite Professional and Burp Suite DAST as paid products, though specific pricing and feature details are not available on the main product page.

Source
OWASP ZAP: Can it replace a penetration test?

No. It automates checks for known vulnerability classes against endpoints it can reach. It does not reason about business logic, chain findings into an attack, or test authorisation between accounts, which is most of what a tester actually does.

OWASP ZAP: Does it run in CI?

Yes, through the official Docker images and the Automation Framework, which defines scan jobs in YAML so configuration lives in the repository. A baseline passive scan is the usual starting point because it is fast and non-intrusive.

OWASP ZAP: How does it compare to Burp Suite?

Burp Suite Professional is the more polished manual testing tool and has a stronger scanner and extension ecosystem, but it is licensed per tester and Burp Suite Enterprise per target. ZAP is the better fit where cost per target is the binding constraint; many teams use both.
