The short version
- Each has a real cost: Frontegg detailed per-unit pricing beyond the free tier is not published, requiring use of an online calculator or sales contact to estimate costs.; 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: Frontegg covers Hosted login, OWASP ZAP covers Intercepting proxy.
- Prices and features above were last checked on 30 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Frontegg
- Detailed per-unit pricing beyond the free tier is not published, requiring use of an online calculator or sales contact to estimate costs.
- Advanced fraud protection and multiple environments are Enterprise-only, unavailable on the Pay As You Go plan.
- The 7,500 free monthly active users is comparatively modest next to some competitors' free tiers.
- As a broader CIAM platform, it can be more complex to integrate than lighter-weight developer-first auth tools for smaller apps.
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
Frontegg: What does Frontegg cost?
Frontegg's Pay As You Go plan is free up to 7,500 monthly active users, after which pricing scales with users, enterprise connections and M2M tokens via an online calculator; Enterprise pricing is custom.
SourceOWASP 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.
Frontegg: Is there a free plan and what are its limits?
Yes, the free Pay As You Go plan includes 7,500 monthly active users, 5 enterprise SSO/SCIM connections, unlimited organizations, and a custom domain.
SourceOWASP 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.
Frontegg: How is usage metered?
Pricing is consumption-based, driven by monthly active users, monthly enterprise connections (SSO/SCIM), and monthly M2M tokens, with customers paying only for usage beyond the free 7,500-user threshold.
SourceOWASP 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.
