The pre-launch control panel for vibe-coded apps
The pre-launch control panel for vibe-coded apps: security, SEO, and AI visibility in one scan.
This is the cleanest category-defining frame because the product truly spans all three jobs, and the page repeatedly positions it as the last step before shipping.
The alternative to manual security audits and piecing together separate SEO tools.
CheckVibe bundles vulnerability scanning, SEO checks, AEO checks, and fix prompts into one workflow, which is exactly what users would otherwise cobble together from multiple tools and docs.
A pain-killer for teams shipping with AI code assistants: find the mistake, then paste the fix back into the agent.
The strongest differentiator is not just detection; it is the agent-native remediation loop for Cursor, Claude, and Windsurf, which fits the actual behavior of the target user.
Primary user
Indie founders and solo builders shipping vibe-coded SaaS apps on Supabase, Firebase, Vercel, Cursor, or Replit
ICP #1
Indie founder shipping a weekend MVP on Supabase and Cursor
Pain
They move fast enough to miss exposed keys, bad RLS, missing headers, and other launch-blocking mistakes until a customer or teammate spots them.
Why this solves
CheckVibe is built for copy-paste workflows: one URL scan, BaaS-aware findings, and fix prompts that can be pasted straight back into Cursor or Claude.
ICP #2
Agency lead delivering client websites and SaaS prototypes under deadline
Pain
They need to hand over projects without embarrassing security gaps, but they do not have time to run full manual audits or write security reports from scratch.
Why this solves
CheckVibe produces a unified report with severity, ownership, and shareable outputs, plus specific remediation prompts that let an agency patch issues fast and prove diligence to clients.
ICP #3
DevOps or SaaS platform engineer owning launch readiness and trust signals
Pain
They are responsible for both production risk and customer confidence, including live monitoring, audit trails, and whether AI search systems can actually find the company.
Why this solves
CheckVibe combines security scanning, continuous monitoring, and SEO/AEO visibility checks in one workflow, so they can catch regressions and improve discoverability without juggling separate tools.
Strengths
- +The product promise is unusually concrete: 100+ checks in under 30 seconds, with named outputs like Supabase anon key exposure, CSP, TLS, and AI crawler access.
- +The site nails the workflow fit for AI-coded apps by showing fix prompts for Claude, Cursor, and Windsurf instead of generic remediation advice.
- +The inclusion of real use cases and testimonials from founders, agencies, and engineers makes the product feel already adopted in the exact market it targets.
Weaknesses
- −The homepage is trying to sell too many things at once: scanner, SEO, AEO, AI fixes, threat detection, reports, MCP, and monitors. The result is category blur.
- −The page leans on jargon like AEO before proving why a user should care beyond SEO, and the distinction between Google ranking and AI citations is explained but not yet emotionally compelling.
- −The CTA hierarchy is weak: there is no obvious primary action beyond a generic 'Scan Your Site,' and the free-to-paid transition is still vague.
- −The repeated testimonials are strong but feel redundant and slightly overstuffed, which makes the page look padded rather than sharpened.
- −The landing page does not sufficiently separate the urgent security pain from the growth/discoverability angle, even though those are two different buying motivations.
Fix these
- Split the homepage hero into two explicit paths: 'Scan for security' and 'Check Google + AI visibility,' then let users choose their intent immediately.
- Add a before/after example report with one real exposed key, one SEO issue, and one AEO issue so buyers can see the output quality instantly.
- Create a tighter pricing narrative around who pays for what: free scan, paid fix prompts, paid monitoring, paid team reporting.
- Replace some testimonials with one quantified proof point per segment, such as time saved, issues caught, or launches accelerated.
- Add a sharp comparison page against Snyk, Detectify, and Semrush to frame CheckVibe as the only tool designed for vibe-coded apps.

FAQ
Do I need to connect my codebase?
No. CheckVibe starts from a URL, so you can scan a live site in seconds. That makes it useful for founders, agencies, and anyone who wants a fast pre-launch check.
Is this only for security?
No. Security is the first job, but the report also covers SEO and AI visibility. The point is to know whether your app is safe, indexable, and readable by modern AI systems.
Will this help with Supabase or Firebase apps?
Yes. The scanner is BaaS-aware and looks for common issues in Supabase, Firebase, and Clerk setups. That is where a lot of fast-moving apps accidentally leave the doors open.
What do I do with the findings?
Fix them directly from the report. Each issue includes ownership, severity, and copy-paste prompts for Claude, Cursor, or Windsurf so you can move from finding to fix quickly.
How is this different from Snyk or Semrush?
Those tools solve parts of the problem. CheckVibe is built specifically for vibe-coded apps and combines security, SEO, and AI visibility in one workflow, from one URL.
Your Cursor app may be leaking keys. CheckVibe scans a URL for 100+ security issues, plus SEO and AI visibility, in under 30 seconds. Built for vibe-coded SaaS. Built for people who copy-paste fixes back into Claude, Cursor, or Windsurf. https://checkvibe.com
I kept seeing the same launch mistake. Founders ship a weekend MVP, then miss exposed Supabase keys, weak headers, or broken AI crawler access. So we built one scan that catches the mess, grades the site, and gives copy-paste fixes. That’s CheckVibe.
100 checks is cheaper than one breach. Especially if your app was built in Cursor, deployed on Supabase, and “we’ll clean it up later” became the product strategy. CheckVibe finds the obvious stuff before users, clients, or hackers do.
I scanned a site in 30 seconds. Found: - exposed Supabase/Firebase surface area - missing CSP - weak TLS settings - AI crawler access problems - SEO issues blocking Google Then it handed back fix prompts for Claude, Cursor, and Windsurf. That workflow matters.
Founders do not want another dashboard. They want one answer: is this thing safe, findable, and ready to ship? That’s why CheckVibe combines security, SEO, and AI visibility in one report instead of making you juggle five tools.
We built the last scan before launch. Paste a URL. Get 100+ security checks, SEO checks, AEO checks, and fix prompts in under 30 seconds. If your app is vibe-coded, this is the part where you make it real.
The best bug report is a fix prompt. Not a PDF that gets ignored. Not a vague checklist. CheckVibe tells you what broke, why it matters, and what to paste into Claude Code or Cursor to fix it fast.
SEO tools miss the AI visibility problem. Your site can rank and still be invisible to ChatGPT, Claude, Perplexity, and the rest. CheckVibe checks both: classic search and AI citations. Because discovery is changing and most sites are not ready.
One URL gives you the whole picture. Security risk. SEO gaps. AEO problems. Monitoring. Shareable report. If you are shipping fast, the useful thing is not more theory. It is one scan that shows what to fix next.
If you ship with Supabase, Firebase, Clerk, Vercel, Cursor, or Replit, this is for you. CheckVibe is the pre-launch pass that catches the stuff your AI assistant won’t mention unless you ask the right question.
Angle: security first
Most indie SaaS launches do not fail because the idea is bad. They fail because something obvious was missed. An exposed key. A weak header setup. Bad TLS. A login flow that was never really hardened. The problem with AI-built apps is speed. You can go from blank page to deployed product before your brain catches up with the risk. That is why we built CheckVibe. Paste in a URL and it scans for 100+ security issues in under 30 seconds, then gives copy-paste fix prompts for Claude, Cursor, and Windsurf. Not a report for a security team that does not exist. A practical output for builders who actually ship. If you are launching on Supabase, Firebase, Clerk, Vercel, or Replit, you need a fast way to catch the mistakes before users do.
Angle: security + growth
There are two questions every new SaaS should answer before launch: 1. Is this site safe? 2. Can anyone find it? Most tools only answer one. Security scanners ignore discoverability. SEO tools ignore risk. AEO is still mostly an afterthought. CheckVibe combines all three in one scan. Security findings. SEO visibility. AI visibility. That matters because the modern launch problem is not just getting indexed by Google. It is also being readable by ChatGPT, Claude, Perplexity, Google AI Overviews, Copilot, Meta AI, and Mistral. If your app is built with AI tools, the remediation loop should also be AI-native. Find the issue. Paste the fix back into the agent. Ship. That is the workflow we built for.
Angle: agency and ops
A lot of agencies and small product teams do excellent work right up until handoff. Then the audit becomes a scramble. Who owns the issue? What is actually broken? Can we prove we checked the basics? Is the site ready for search and AI discovery? CheckVibe was built to remove that scramble. One scan. A unified report. Severity, ownership, deep links, and shareable output. Live monitoring if you want to catch regressions. For agencies, that means faster handoff and fewer embarrassing follow-ups. For founders, it means a cleaner launch. For platform teams, it means one workflow for risk and visibility. I think this category is bigger than “security scanner” or “SEO tool.” It is the pre-launch control panel for vibe-coded apps.

Security, SEO, and AI visibility in one scan
Description
Scan a URL for 100+ security issues, SEO gaps, and AI visibility problems in under 30 seconds. Built for vibe-coded apps, with copy-paste fixes for Claude, Cursor, and Windsurf.
Maker's first comment
I built CheckVibe because I kept seeing the same pattern: people ship fast with AI coding tools, then discover the basics were missed too late. A lot of these issues are not exotic — they are exposed keys, weak headers, broken indexing, or AI crawlers that cannot read the site properly. What made this worth building was the workflow, not just the scan. The output had to be something a solo builder could actually use immediately, so every finding maps to a practical fix prompt for Claude, Cursor, or Windsurf. The goal is not to hand you a pile of warnings. The goal is to help you ship something safer and easier to find without slowing you down. If you try it, I’d love feedback on the report clarity and whether the security vs SEO vs AEO split feels obvious enough on first use.
Pinned maker comment
Would love feedback on the scan output, the prioritization of findings, and whether the AI fix prompts are actually useful in your workflow.
Meta
Your AI-built app has blind spots.
Hypothesis: founders shipping with Cursor, Supabase, or Replit will pay for a fast pre-launch scan that catches security issues and visibility gaps before launch. CheckVibe scans one URL for 100+ security checks, SEO, and AI visibility in under 30 seconds, then gives fix prompts you can paste back into your coding assistant.
Google Search
Check a site for security and SEO risks
Hypothesis: people searching for security audits, website scanners, or AI visibility checks want one tool that does all three without enterprise setup. CheckVibe scans a URL for security issues, SEO problems, and AI crawler access in under 30 seconds, with actionable fixes instead of abstract findings.
Reddit Promoted
Built a scanner for vibe-coded apps.
Hypothesis: indie hackers and solo builders on Reddit will respond to a tool that catches the common launch mistakes from AI-generated code and gives fixes they can paste back into their agent. CheckVibe scans security, SEO, and AI visibility from just a URL, then turns findings into practical remediation prompts.
