Which Scanner Should You Choose?
Choose CheckVibe if you're a developer who wants instant, automated security scanning without configuring a proxy or learning pentesting. Especially if you're building with modern stacks (Next.js, Supabase, Vercel) or using AI code editors. CheckVibe is the only scanner with BaaS auditing, vibe coding detection, and MCP server integration for AI editors.
Choose OWASP ZAP if you want a free tool, have security knowledge, and want hands-on control over your scanning configuration. ZAP is the best option for developers who want to learn security testing from the ground up.
Choose Snyk if your primary concern is vulnerable dependencies in your package.json or container images, and you want automated PRs to fix them. Snyk is the best-in-class SCA tool.
Choose Burp Suite if you're a professional pentester or security consultant who needs deep, manual testing capabilities and industry-recognized results.
Choose Aikido if you want a single platform combining SAST, DAST, SCA, and cloud posture management, and you have the budget for team-tier pricing.
Choose Detectify if you need continuous external attack surface monitoring with crowdsourced vulnerability research, and you are a mid-size company with a security team.
Choose Intruder if you are an SMB that needs compliance-friendly vulnerability scanning (SOC 2, ISO 27001) with a simple setup and no security expertise required.
Choose HostedScan if you want the power of open-source tools (ZAP, OpenVAS, Nmap) without managing infrastructure, and you need basic scheduled scanning with a free tier.
Can You Use Multiple Scanners?
Yes — and you should. These tools are complementary:
- CheckVibe covers your live site's runtime security (100+ checks + site crawling + BaaS audits)
- Snyk covers your dependency supply chain
- OWASP ZAP or Burp adds manual deep-dive testing when needed
Using CheckVibe alongside Snyk gives you both application security and supply chain security with minimal setup effort. For teams with compliance requirements, adding Intruder or Detectify for continuous monitoring provides an additional layer.
The key principle is defense in depth: no single scanner catches everything. A combination of DAST (runtime scanning), SCA (dependency analysis), and periodic manual testing gives you the most comprehensive coverage.

FAQ
Which scanner is best for startups?
For early-stage startups and indie hackers, CheckVibe offers the best balance of coverage, speed, and pricing. The free tier gives you 4 scans per month with a single project, which is enough to establish a security baseline. As you grow, the $19/month Starter plan covers 30 scans. If your stack uses Supabase, Firebase, Vercel, or Netlify, CheckVibe is the only scanner that includes specific checks for these platforms. HostedScan is another budget-friendly option with a free tier, though it lacks BaaS and AI code detection.
Is OWASP ZAP still relevant?
Yes. OWASP ZAP remains one of the most capable open-source security scanners available. It receives regular updates, has a large community, and its active scanning mode can find vulnerabilities that simpler tools miss. The main drawback is the setup time and learning curve — you need to understand proxy configuration, scan policies, and how to interpret results. For developers who want to learn security testing fundamentals, ZAP is an excellent educational tool. For developers who want quick results without configuration, a cloud-based scanner like CheckVibe is more practical.
Do I need both Snyk and DAST?
Yes, they cover fundamentally different attack surfaces. Snyk scans your source code and dependency tree for known vulnerabilities (CVEs) — it tells you if a library you are using has a published security flaw. DAST tools like CheckVibe, ZAP, or Burp scan your running application for runtime vulnerabilities — SQL injection, XSS, CSRF, misconfigured headers, exposed secrets. You can have zero dependency vulnerabilities and still be wide open to SQL injection. You can have a perfectly coded application and still be using a compromised library. Both layers are necessary for comprehensive security.
Can I replace a pentest with scanning?
Automated scanners are excellent for catching known vulnerability patterns at scale, but they cannot fully replace a skilled human pentester. Scanners follow predefined rules and payloads — they excel at finding common issues like missing headers, known CVE patterns, and standard injection vectors. A pentester applies creative reasoning, chains multiple low-severity findings into high-impact attacks, tests business logic flaws, and identifies vulnerabilities that require contextual understanding. The best approach is to use automated scanning continuously (every deploy, every day) and supplement with periodic human pentests (quarterly or before major launches). Automated scanning handles the 90% of routine checks; pentesting handles the 10% that requires human intelligence.
