Najlepszy skaner bezpieczeństwa dla aplikacji AI: FixVibe vs Burp

What to evaluate

Not all scanners are created equal. For AI-generated SaaS, a few dimensions matter more than others.

• Time to first scan. Can you paste a URL and get results in minutes? Or do you need to install a proxy, configure a browser, or deploy an agent?
• BaaS platform awareness. Real checks against Supabase RLS, Firebase rules, Clerk config, AWS Cognito, not generic OWASP rules. AI-generated SaaS almost always uses a managed auth or database service.
• JS bundle secret detection. Provider-specific patterns for Stripe, Anthropic, Supabase, AWS, Google, OpenAI — not generic entropy heuristics. Bundle secrets are the most common finding in AI-generated apps.
• Framework awareness. Recognizing Next.js (App vs Pages Router), Vite SPA rewrites, Vercel / Netlify / Cloudflare Pages deployments, and knowing what a real /.next/build-manifest.json looks like vs a SPA fallback.
• Bounded, authorized active probes. SQLi, XSS, SSTI, IDOR, CORS, redirects — but only against domains you verify ownership of. Legal and responsible.
• First-class REST API and MCP. Can you integrate scanning into CI / Cursor / MCP? Or is the web UI the only path?
• False-positive rate. How many findings are noise? How much triage overhead per report?
• Speed to report. Seconds? Minutes? Hours? If a scan takes 10 minutes, you can't run it on every commit.

FixVibe

FixVibe is a DAST built for AI-generated SaaS. It runs on every tier for passive scans (free tier: 3/month; paid: unlimited). Active scans require domain verification and are available on Hobby and up.

Strengths

• BaaS-native. Real checks for Supabase RLS, Firebase rules, Clerk, Cognito, and other managed services common in AI-generated apps. Not generic OWASP rules.
• Tuned for AI code. JS bundle inspection with provider-specific secret patterns. Framework awareness of Next.js, Vite, and deployment platforms. 250+ vulnerability classes, many specific to how AI tools fail.
• Fast. Passive scans complete in 20-90 seconds. No setup, no proxy, no install. Paste a URL, wait for the report.
• Integration-first. REST API, MCP server, webhooks. Audit logs, transparent changelog, templated AI fix prompts you can paste into Cursor or Claude Code.

Weaknesses

• DAST-only. No static analysis (SAST). Can't scan your source code for hardcoded secrets or dangerous function calls before you deploy. Use Snyk or Semgrep in CI for that layer.
• Public URLs only. Can't scan localhost or internal networks. If your production app is behind auth or IP-restricted, FixVibe still scans it, but staging / dev work needs a public URL.
• No on-premises option. SaaS-only. If compliance requires air-gapped scanning, FixVibe isn't available.

Burp Suite Pro

Burp is the gold standard for manual web application testing. It's a browser proxy + interactive workbench that lets you craft custom attacks, chain exploits, and explore application behavior by hand.

Strengths

• Deepest manual workbench. If you need to custom-craft an exploit, chain attack steps, or test app-specific logic, Burp is the best tool. No automated scanner replaces a human tester with Burp.
• First-class active scanning. Burp's active scanner is mature and comprehensive. It can find second-order vulnerabilities and business-logic bypasses automated tools miss.
• Wide protocol support. Not limited to HTTP. Can scan APIs, WebSockets, exotic protocols.

Weaknesses

• Manual setup overhead. Requires proxy configuration, browser cert install, scope definition. 15-30 minutes before the first request.
• No BaaS awareness. Can't audit Supabase RLS policies or Firebase rules. You're on your own to verify those.
• Expensive. $399/year or $3999/year for deployment scans. Not practical for indie developers.

OWASP ZAP

ZAP is the free, open-source alternative to Burp. It's a browser proxy and active scanner maintained by OWASP. Community-driven, no vendor lock-in.

Strengths

• Free and open-source. No licensing. Community-maintained. Can be self-hosted or run as a Docker container in CI.
• Scriptable. CLI and APIs for integration into CI/CD pipelines. Can run automated scans nightly without human intervention.

Weaknesses

• High false-positive rate. ZAP tends to flag generic OWASP patterns without context. Triage overhead is high for AI-generated apps.
• Generic, not AI-aware. No BaaS checks, no provider-specific secret patterns, no framework awareness. Treats all apps the same.
• Older defaults. Prefers HTTP to HTTPS, assumes traditional auth flows. Not tuned for modern SaaS.

SAST / SCA complements (Snyk, Semgrep, SonarQube)

These tools analyze source code, not the running application. They're not DAST competitors — they're complements that catch what DAST can't.

• Snyk — dependency vulnerability scanning. Runs in CI, flags outdated npm, Python, and Go packages with known CVEs. Free for open-source, paid for private repos. Integrates with GitHub.
• Semgrep — pattern-based static analysis. Can catch hardcoded secrets, dangerous function calls, and app-specific patterns you define. Free tier for 5 rules; paid for more.
• SonarQube — code quality and SAST combined. Catches bugs, security issues, and code smells. Expensive; mostly used in enterprise.

Network / infrastructure scanners (Nessus, Qualys)

These tools scan network infrastructure and OS-layer vulnerabilities, not web applications. They're not a fit for web apps unless you're also managing your own servers.

• Nessus — network vulnerability scanner. Useful if you deploy to your own VMs. Not useful for Vercel / Netlify SaaS.
• Qualys — cloud-based infrastructure scanning. Similar scope to Nessus. Designed for enterprises managing their own data centers.
