   Claude #1Gemini #1

   The most reliable authenticated scanner for modern SPAs — its browser-driven crawl (embedded Chromium) actually renders JS, follows client-side routing, and recorded login sequences plus session-handling rules keep auth state through token refresh and CSRF flows better than any peer; Burp's scan engine has the lowest false-positive rate on DOM-based XSS, prototype pollution, and injection classes, and the ecosystem (BApp extensions, Bambda, DOM Invader for client-side testing) is unmatched.

   Claude The most reliable authenticated scanner for modern SPAs — its browser-driven crawl (embedded Chromium) actually renders JS, follows client-side routing, and recorded login sequences plus session-handling rules keep auth state through token refresh and CSRF flows better than any peer; Burp's scan engine has the lowest false-positive rate on DOM-based XSS, prototype pollution, and injection classes, and the ecosystem (BApp extensions, Bambda, DOM Invader for client-side testing) is unmatched.

   Gemini Industry-benchmark vulnerability detection engine paired with an embedded Chromium crawler engineered specifically for dynamic JavaScript execution, DOM state changes, and client-side routing; near-tied with Bright Security on modern crawl depth, but earns the top spot due to payload accuracy, research-backed AST/DAST depth, and versatile session-handling rules that track dynamic tokens across asynchronous SPA states.

   Where it falls short

   per Claude It's a semi-manual pentester's tool, not a hands-off CI scanner — the Enterprise edition scales it but the Pro workflow assumes an operator, and per-seat licensing plus a learning curve make it wrong for developers wanting fire-and-forget automation.

   per Gemini High configuration overhead for complex multi-step SSO or token-refresh flows without manual recorded login sequences; not for developer teams needing zero-config CI/CD pipeline automation without AppSec involvement.

   Claude #2Gemini #4

   Best-in-class fully-automated authenticated DAST for teams — mature JS-rendering crawler, robust form/OAuth/SSO login recording with session detection, and proof-based scanning that auto-verifies exploitable findings to cut false positives, which is exactly what AppSec teams running unattended scans at scale need; strong CI/CD and issue-tracker integration.

   Gemini Heavy-duty proprietary Chromium crawling engine that thoroughly executes client-side JavaScript, uncovers dynamically rendered endpoints, and pairs authenticated discovery with proof-based scanning to automatically verify exploitable vulnerabilities.

   Where it falls short

   per Claude Expensive enterprise licensing and closed-source; overkill for individuals or small teams, and its automation can still miss deep multi-step SPA workflows a skilled human would reach in Burp.

   per Gemini Exceptionally resource-heavy scan runs and slow scan speeds on large SPAs, combined with enterprise-tier pricing; not for teams requiring rapid PR-level feedback loops or operating on limited budgets.

   Claude #3Gemini #3

   Purpose-built for developer/CI-first DAST on modern apps and APIs — configuration-as-code (YAML), first-class GraphQL/REST/SPA support, and authenticated scanning wired into pipelines make it the strongest fit for shift-left teams who want DAST to run on every PR without a security specialist driving it; wraps and hardens a ZAP-based engine with far better auth ergonomics.

   Gemini Exceptional developer-centric CI/CD integration that handles authenticated SPAs by ingesting existing browser test suites (Playwright, Cypress) to bootstrap authenticated sessions and map backend REST/GraphQL endpoints with minimal friction.

   Where it falls short

   per Claude Depth of vulnerability coverage and manual-testing power trail Burp/Invicti; it's built for automated regression in CI, not deep adversarial assessment, and relies on you providing accurate app/API specs.

   per Gemini Autonomous crawling is weak without supplemental API schemas or pre-recorded browser test journeys; not for teams attempting black-box scanning against SPAs lacking OpenAPI/GraphQL documentation or automated test suites.

   Claude #5Gemini #2

   Purpose-built for modern client-rendered web applications and APIs, leveraging headless browser automation with direct support for recorded Playwright/Puppeteer authentication flows and seamless OAuth/Bearer token maintenance; near-tied with Burp Suite for SPA DOM coverage while offering lower false-positive rates on client-side vulnerabilities.

   Claude Developer-focused DAST/DAST-for-APIs engineered for CI/CD with an emphasis on low false positives via automatic validation of findings; strong on modern SPA and API (REST/GraphQL) targets with authenticated scanning and pipeline integration, designed to run against every build.

   Where it falls short

   per Claude Smaller footprint, ecosystem, and independent track record than the leaders; coverage breadth and community knowledge are thinner, so it's a weaker choice where proven depth or extensibility matters most.

   per Gemini Expensive commercial licensing and a smaller third-party ecosystem; not for teams needing broad attack surface discovery or legacy monolithic web application recon.

   The strongest free/open-source option — AJAX Spider (browser-driven crawl) handles JS-heavy SPAs, scriptable authentication and context/session management cover token and form logins, and full automation via the Automation Framework, Docker, and API make it genuinely CI-capable at zero license cost; huge community and add-on marketplace.

   Gemini Fully open-source and free, featuring an AJAX Spider powered by browser automation and flexible extensibility through the ZAP Automation Framework and Zest scripting for injecting dynamic auth headers and session cookies.

   Where it falls short

   per Claude Higher false-positive/noise rate and more manual tuning than commercial peers; authenticated scans of complex SPA/token flows often need hand-written scripts, so it demands real operator effort to match paid tools' out-of-box results.

   per Gemini AJAX spidering and session persistence on modern dynamic SPAs are brittle and prone to state loss during scans; not for teams without the internal engineering bandwidth to continuously write and maintain custom authentication scripts.
