The short version

  • Only OWASP ZAP has a free tier, so it costs nothing to try first.
  • Each has a real cost: CitizenLab citizenLab has rebranded to Go Vocal and the product now sells under govocal.com; 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: CitizenLab covers Participatory Budgeting, OWASP ZAP covers Intercepting proxy.
  • Prices and features above were last checked on 30 August 2026.

  • Pre-release regression scanning of an internal application that would never justify a commercial DAST subscriptionnot CitizenLab

Where each one falls short

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

CitizenLab

  • CitizenLab has rebranded to Go Vocal and the product now sells under govocal.com
  • No prices are published on the plans page; every tier requires scheduling a demo
  • The Essential plan allows only 1 active project and 1 admin seat, with no project manager seats
  • Standard is limited to 4 admin seats and 5 project manager seats, and Premium to 8 admin seats and 25 project manager seats
  • Standard restricts Sensemaking to Light, capped at 30 inputs; auto-insights require Premium
  • The integrated Konveio document annotation and Echo blended engagement methods are excluded from Standard and require Premium
  • Auto-translation on Premium is limited to 3 languages
  • Custom fonts and other premium styling options are Premium only
  • Priority support is Premium only
  • Plans are split by population band, with separate ladders for cities under and over 100K population

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

CitizenLab: How many projects can Essential tier teams manage?

The Essential tier is designed for teams starting small and is limited to 1 active project with 1 admin seat and no project manager seats.

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.

CitizenLab: How many projects can Standard and Premium tiers manage?

Both Standard and Premium tiers support unlimited projects. Standard includes 4 admin seats and 5 project manager seats, while Premium includes 8 admin seats and 25 project manager seats.

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.

CitizenLab: Does Enterprise tier have any user seat limits?

No, the Enterprise tier is designed for organizations aiming to embed engagement deeply within their infrastructure and includes unlimited admin seats and project managers.

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.

CitizenLab: What are the specific pricing amounts for each tier?

Specific pricing amounts are not disclosed on the plans page. The company directs interested organizations to talk to their team for personalized pricing offers.

Source
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.
