Best Security Scanners for Vibe-Coded Apps (2026 Comparison)
Honest comparison of 7 vibe coding security scanners. Features, pricing, speed, and what each tool catches -- from someone who built one of them.
The best security scanner for vibe-coded apps depends on what you need. SafeToShip is the fastest (60-second URL scans, free). Vibe App Scanner offers the deepest analysis with human review. Aikido is the right choice if you need a full security platform. The right pick depends on your scan type, budget, and how technical you are. Here is what we found testing all of them.
Why vibe-coded apps need specialized scanners
Traditional security tools like Snyk, SonarQube, and Burp Suite were built for code written by human developers following established patterns. They are excellent at what they do. But AI-generated code breaks differently.
When you ask Lovable to build a full-stack app, it might disable Row Level Security because it is faster to get a working prototype without it. When Cursor generates a Stripe integration, it might put your secret key in a client component because that is the most direct path to "it works." When Bolt scaffolds an API, it might leave debug endpoints exposed because the AI never thought to remove them. These are not edge cases. They are the default output of vibe coding tools. A Veracode study from 2025 found that 45% of AI-generated code contains OWASP Top 10 vulnerabilities. CodeRabbit's analysis showed AI-generated code has 2.74x higher security vulnerability rates compared to human-written code.
Traditional scanners do not check for Supabase RLS being disabled, Firebase security rules left in test mode, or client-side JavaScript bundles containing sk-ant- API keys. That is the gap these specialized tools fill.
How we tested
We tested each scanner against the same five apps: two built with Lovable, one with Bolt.new, one with Cursor, and one with Replit. For each scanner, we evaluated vulnerability detection depth, scan speed, ease of use for non-technical users, pricing, quality of fix instructions, and platform-specific support.
Disclosure: SafeToShip is our product. We built it because we saw gaps in existing tools. We have tried to be fair in this comparison. If a competitor does something better, we say so. If you disagree with any assessment, let us know.
The comparison
SafeToShip -- Our pick for speed and simplicity
SafeToShip is a URL-first security scanner built specifically for vibe coders. Paste a URL, get a scored audit in 60 seconds with 10 check categories. Paid plans unlock AI fix prompts tailored to your specific AI tool -- Cursor, Lovable, Bolt, Replit, or Claude.
Strengths. Fastest time-to-result of any tool we tested. Quick scans are free with no signup required. You see your score and finding titles immediately. Deep scans connect to your GitHub repo for combined source code and URL analysis, catching issues that URL-only scanning misses. Fix prompts are customized per AI tool, so you can paste them directly into Cursor or Lovable and get a working fix -- not a generic code snippet you have to adapt. The UI is designed for people who have never touched a security tool before.
Weaknesses. SafeToShip is a newer tool with a smaller secret pattern library than Vibe App Scanner. Deep scans require a GitHub connection, which some users prefer not to grant. Every scan is fully automated -- there is no manual review by a security professional. CI/CD integration is not available yet, though it is on the roadmap.
Pricing. Free unlimited quick scans. $9 one-time to unlock the full report for a single scan. $24/mo Pro for unlimited full results, deep scans, trust badge, and monitoring.
Best for: Solo founders who want the fastest possible security check before shipping. Ideal if you are non-technical and need plain-English results with copy-paste fixes.
Vibe App Scanner -- Best for deepest analysis
Vibe App Scanner is an external DAST scanner built by a security engineer with over 15 years of experience. It runs 150+ secret patterns and every scan is manually reviewed by a human security professional.
Strengths. The most thorough scanning of any indie tool on this list. 150+ secret patterns is the largest library we have seen. The manual review by a security professional is a genuine differentiator -- it catches logic issues and context-dependent vulnerabilities that automated tools miss. Vibe App Scanner also has extensive platform-specific content: checklists, safety guides, and tutorials for every major vibe coding platform. The team discovered the vulnerabilities behind CVE-2025-48757, which exposed 170+ Lovable apps. That kind of credibility matters.
Weaknesses. Scans take 15 to 20 minutes compared to 60 seconds for a SafeToShip quick scan. There is no free scan -- the cheapest option is $5 for a Starter Scan. You need to create a dashboard account to view results. There is no source code or GitHub integration, so it only catches what is visible from the outside. The manual review, while thorough, adds time.
Pricing. Starter Scan $5 (quick), Launch Scan $14 (deep), Pro $29/mo (4 Launch scans + unlimited Starter scans).
Best for: Founders who want the most thorough, human-reviewed security audit and do not mind waiting 15 to 20 minutes. The CVE discovery track record adds real credibility.
Aikido Security -- Best full security platform
Aikido Security is a unified AppSec platform covering SAST, DAST, SCA, secrets scanning, container scanning, cloud security, and AI-powered pentesting. It has an official Lovable partnership, has raised over $84M in funding, and is valued at over $1B.
Strengths. By far the most comprehensive security tool on this list. It covers code, dependencies, containers, cloud infrastructure, and runtime -- all in one platform. The built-in Lovable integration runs automatically on every Lovable deploy. Enterprise-grade organizations like the Premier League, SoundCloud, Niantic, and Revolut use it. Aikido Infinite offers AI-powered pentesting. There is a free tier available, and their open source contributions through Opengrep give back to the community.
Weaknesses. Aikido is overkill for most solo vibe coders. The dashboard is powerful but overwhelming if you just want to know whether your Lovable app is leaking secrets. There is no simple URL-first scanning -- you need to connect repos, cloud accounts, or container registries to get full value. Setup requires multiple integrations. The tool is designed for teams with some security knowledge, not complete beginners. Advanced features are enterprise-priced.
Pricing. Free tier available. Paid plans are team-based and not published publicly.
Best for: Teams or funded startups that want a full security platform, not just vibe coding checks. If you have a security-conscious CTO or are heading toward SOC 2 compliance, Aikido is the right choice.
ZeriFlow -- Best for CI/CD integration
ZeriFlow uses a two-layer approach: URL scanning with 80+ checks, plus a CI/CD GitHub Action that runs Claude Sonnet to filter false positives from each finding.
Strengths. 80+ checks across 12 categories in about 30 seconds. The standout feature is CI/CD integration via GitHub Actions -- scans run automatically on every commit so you catch issues before they reach production. The AI false-positive filtering genuinely reduces noise. Copy-paste fix snippets are provided for Vercel, Nginx, and Next.js middleware. At $4.99/mo for 5 CI/CD scans, it is the cheapest ongoing option.
Weaknesses. ZeriFlow is a newer tool with a smaller community. It does not test Supabase RLS or Firebase security rules. The URL scanner does not check database access controls. There is no mobile app scanning.
Pricing. Free first scan. $4.99/mo for CI/CD integration. Token packs for higher volume.
Best for: Developers who want security checks integrated into their deploy pipeline. If you push to GitHub and want automated scans on every commit, ZeriFlow is the best option.
VibeWrench -- Best all-in-one pre-launch tool
VibeWrench goes beyond security. It offers 18 free scanners covering security, SEO, page speed (Lighthouse), accessibility (WCAG), legal compliance (GDPR), and more. Built by solo developer Andrei K.
Strengths. The breadth is impressive: 18 different scan types in one tool. Security, SEO, speed, accessibility, and legal all in one place. Findings are written in genuinely plain English -- "like leaving your front door unlocked" is the kind of language you will see. It includes a prompt injection scanner for AI apps covering OWASP LLM01, which is a unique addition. Free tier gives you 3 scans per month.
Weaknesses. Jack of all trades, master of none. The security scanning is not as deep as tools focused exclusively on security. There is no Supabase RLS testing or Firebase rules checking. No source code or GitHub integration. The speed and SEO scans, while useful, dilute the security focus -- you might miss that a critical finding is buried among 17 other scan categories.
Pricing. Free (3 scans/month). Paid tiers for more scans.
Best for: Solo founders who want a single pre-launch checklist covering security, SEO, speed, and accessibility. If you would rather run one tool than four, this is it.
AmIHackable -- Cheapest option
AmIHackable is a minimalist URL scanner built by a solo French developer. Paste a URL, get an audit in about 60 seconds.
Strengths. Dead simple. No complex dashboard, no signup friction. Fast results. At $2 per scan, it is the cheapest individual scan available.
Weaknesses. Fewer checks than the other tools on this list. No free tier -- every scan costs $2. Findings and fix instructions are less detailed. No source code scanning. Minimal platform-specific guidance for different AI tools.
Pricing. $2 per scan.
Best for: Quick spot-checks when you just want a basic sanity check for $2.
Lovable Built-in Security Advisor -- Best for Lovable-only users
Lovable v2 includes a built-in security advisor that runs four automated checks before every publish: RLS analysis, database schema review, code vulnerability scanning, and dependency audits.
Strengths. Zero friction. It runs automatically for every Lovable user with no additional tool, no cost, and no setup. It catches the number one Lovable vulnerability -- RLS being disabled -- right in the workflow where you would fix it.
Weaknesses. Only works for Lovable apps. Security researchers have noted it "only checked for existence" of security features, not whether they were properly implemented. It cannot scan apps after deployment. It is limited to what Lovable considers important, so there is no external security headers check, no CORS testing, and no cookie analysis. It cannot catch issues that Lovable itself introduced.
Best for: Lovable users as a first-pass check. Use an external scanner afterward as a second opinion.
What no single scanner catches
Security issues in vibe-coded apps fall into three layers, and most scanners only cover one or two:
Code-level issues include hardcoded secrets, missing auth checks, SQL injection, and RLS misconfigurations. These require source code access to detect. Deep scans and SAST tools catch these.
Config-level issues include missing security headers, exposed .env files, open CORS policies, and insecure cookies. URL scanners catch these by examining what your deployed app exposes to the outside world.
Runtime issues include actual exploitability, session handling flaws, and authentication bypasses. These require dynamic testing or manual penetration testing. No fully automated tool covers this layer completely -- Aikido Infinite's AI pentesting comes closest.
The best approach is to layer your scanning: run a quick URL scan (SafeToShip, ZeriFlow) for config-level issues, plus a deep source code scan (SafeToShip deep scan, Vibe App Scanner, Aikido) for code-level issues. If you are handling sensitive user data or payments, consider manual testing for runtime issues.

Which scanner should you use?
If you are shipping today and need a gut check in 60 seconds, run a SafeToShip quick scan. It is free and gives you the fastest path to knowing whether something is obviously wrong.
If you want the most thorough audit with human review, use Vibe App Scanner. The manual review catches things automated tools miss, and the team's CVE discovery track record speaks for itself.
If you need security integrated into your deploy pipeline, ZeriFlow's GitHub Actions integration means you never ship a commit without a scan.
If you want security plus SEO plus speed plus accessibility in one tool, VibeWrench covers the widest ground.
If you are building a team product heading toward compliance, Aikido is the right platform. It scales from startup to enterprise.
If you just need a basic $2 check, AmIHackable is the cheapest option.
If you are using Lovable and have not checked anything yet, start with Lovable's built-in security advisor, then run an external scanner as a second opinion.
The bottom line: do not skip scanning entirely. Any scanner is better than no scanner. The 60 seconds it takes could save you from being the next headline.
FAQ
Do I need a paid scanner or is a free scan enough?
A free quick scan catches the most common issues: missing security headers, exposed files, and basic secret patterns. But paid scans with source code access catch deeper issues like hardcoded credentials in server files, auth logic flaws, and database misconfigurations that URL-only scanning cannot detect. If you have real users or handle payments, the $5 to $14 for a full scan is worth it.
Can I use multiple scanners?
Yes, and you should. URL scanners and source code scanners find different things. Running a quick URL scan plus a deep source code scan gives you the most complete picture. Most scanners complete in under two minutes, so running two takes less time than reading this FAQ.
How often should I scan?
Scan before every major deploy. If you are iterating rapidly with daily deploys, a CI/CD integrated scanner like ZeriFlow catches issues automatically. Otherwise, scan at least before launch, after adding auth or payment features, and after any AI-generated refactor that touches database or API code.
Are these scanners enough to be fully secure?
No automated scanner catches everything. These tools cover the most common and most dangerous issues in vibe-coded apps, but they are not a substitute for understanding your own app's security model. If you are handling medical data, financial transactions, or other sensitive information, consider a manual security audit in addition to automated scanning. For most vibe-coded MVPs and early-stage products, automated scanning catches the issues that actually get exploited.
