FixVibe vs Burp, ZAP, Snyk and Aikido for AI-built apps
You're choosing a security scanner for an app built with AI coding tools. FixVibe checks the live app and your GitHub repo; Burp Suite and ZAP are general web-app testing tools; Snyk, Semgrep and Aikido focus on source code and dependencies. This guide covers what to evaluate, what each tool is for, and a decision matrix for six common scenarios.
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, and Clerk or Auth0 configuration, not generic OWASP rules. AI-generated SaaS almost always uses a managed auth or database service.
- JS bundle secret detection. Does it recognise the key formats your stack uses (Stripe, Supabase, OpenAI, AWS…) and tell a publishable key from a secret one? Leaked keys in bundles are among the most damaging findings in AI-generated apps.
- Framework awareness. Does it understand Next.js, Vite single-page apps, and hosts like Vercel, Netlify and Cloudflare Pages, so their normal behaviour is not reported as a vulnerability?
- 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 checks live apps built with AI coding tools. Passive scans run on every plan (3 a month on Free, 50 on Hobby, 200 on Pro, fair-use unlimited on Unlimited). Active scans need a verified domain and start on Hobby; GitHub repo scans start on Pro.
Strengths
- BaaS-native. Real checks for Supabase RLS, Firebase rules, and Clerk and Auth0 configuration — the managed services common in AI-generated apps. Not generic OWASP rules.
- Tuned for AI code. 230+ passive checks per URL scan, 130+ active checks on verified domains, and 190+ checks per GitHub repo scan, with awareness of Next.js, Vite, and deployment platforms.
- Fast. A passive scan usually finishes in under a minute. No setup, no proxy, no install. Paste a URL, wait for the report.
- Integration-first. REST API, MCP server and signed webhooks on paid plans. Audit logs, a public changelog, coding-agent prompts for code/config fixes, and operator steps for DNS/provider-owned fixes.
Weaknesses
- Public URLs only. Can't scan localhost or internal networks, so staging and dev work needs a publicly reachable URL.
- No on-premises option. SaaS-only. If compliance requires air-gapped scanning, FixVibe isn't available.
Burp Suite
Burp Suite Professional is a web penetration-testing toolkit: an intercepting proxy, manual testing tools and an automated vulnerability scanner. The free Community Edition includes the manual tools.
Best for: security engineers who need to craft custom attacks, chain steps, and test app-specific logic by hand. It takes setup and skill; it has no built-in knowledge of Supabase or Firebase rules.
OWASP ZAP
ZAP is a free, open-source web app scanner with a large contributor community.
Best for: teams that want a free scanner they run and tune themselves, including in their own CI. Like Burp, it treats every app as a generic web app.
Source-code and dependency scanners (Snyk, Semgrep, Aikido)
These tools analyze your repository rather than the running app. They complement a live-app scanner: they see code paths that never reach production, and miss configuration that only exists there.
- Snyk — dependency (SCA), code (SAST), container and infrastructure-as-code scanning, with a free plan.
- Semgrep — code (SAST), supply-chain and secrets scanning, with a free edition for small teams.
- Aikido — one platform for code, dependencies, secrets, cloud configuration and some dynamic testing, with a free developer plan.
Network and host scanners (Nessus)
These tools assess servers and networks rather than web applications. They matter if you run your own machines; they add little for an app hosted on Vercel or Netlify.
- Nessus — Tenable's vulnerability assessment tool for hosts and networks.
Side-by-side comparison
How the three live-app scanners differ for an AI-built app:
| Aspect | FixVibe | Burp Suite | ZAP |
|---|---|---|---|
| Setup | Paste a URL | Install the app and route a browser through its proxy | Install and configure the scanner |
| Active testing (SQLi, XSS, IDOR) | Yes, on verified domains only | Yes, manual and automated | Yes, automated |
| Price | Free plan + paid plans | Paid; free Community Edition | Free (open source) |
| What it can reach | Public URLs and connected GitHub repos | Anything your machine can reach | Anything your machine can reach |
Decision matrix: which scanner for your scenario?
No single tool is best for every team. Use this matrix to find your fit:
You're shipping a Cursor + Supabase + Vercel SaaS and want a baseline security scan before launch.
FixVibe Free or Hobby. Paste your live URL, run passive scans, get BaaS-aware findings, and copy the right remediation action back to Cursor or your provider console. No setup overhead.
You built a Lovable app on Supabase and want to confirm users can't read each other's data.
FixVibe Hobby or Pro. Run a passive scan for open Supabase tables, then verify your custom domain to run active checks such as IDOR and auth-flow tests.
You have a static Vite SPA on Cloudflare Pages and want scheduled vulnerability scans.
FixVibe Pro with scheduled scans. Verify the domain, schedule re-scans, and send findings to your own endpoint with signed webhooks. Passive scans cover headers, CSP and exposed secrets; active scans add checks such as reflected XSS.
You want to audit your source code for hardcoded secrets and supply-chain risks before each release.
FixVibe Pro or Unlimited, plus a code scanner in CI. FixVibe's GitHub repo scans flag hardcoded secrets, risky code patterns and vulnerable dependencies; Snyk, Semgrep or Aikido can also run in your CI pipeline.
You have a team of security engineers who need a custom-attack workbench and are willing to invest in tool mastery.
Burp Suite Professional. The standard workbench for manual testing. Use it alongside an automated scanner such as FixVibe.
Your organisation requires on-premises scanning and compliance audit trails.
A self-hosted toolchain. FixVibe is SaaS-only. ZAP can run on your own infrastructure, and Nessus covers host and network assessment.
Next steps
Pick the scanner that matches your scenario. Combine a live-app scanner (FixVibe, Burp, ZAP) with a code scanner (Snyk, Semgrep, Aikido) for full coverage. For a comprehensive pre-launch audit, see Pre-launch SaaS security checklist.
