This is a very timely problem. Vibe-coded apps can get to “working demo” incredibly fast, but access control and production security are exactly where small mistakes can become painful later.

I like the idea of making security checks feel as lightweight as pasting in a URL instead of requiring a full security workflow. When Perfai finds a live vulnerability, how much of the fix is automated versus guided for the developer to review and apply?

Great question! If you built with Replit, Lovable, or any AI coding tool, just run "Fix all Perfai issues" and it will instantly fix them. Each finding comes with the exact context your coding agent needs to apply the fix.


For everything else, our Fix Agent writes a suggested fix for each issue, with the permission gap explained and proof of how we exploited it. Your developer reviews and applies it. We keep a human in the loop on purpose, since access control changes can break real user flows if applied blindly.


Every finding ships in a pentest-style report, and we run drift detection too, so if a new gap shows up as your app changes, you'll catch it.

Great concept. My team runs into this problem consistently. Even with AI guardrails and instructions, we have to spend valuable hours testing for vulnerabilities.

Maker

 
Thank you! Your team's experience is exactly why we built this. AI guardrails help, but they can't replace real testing, and doing it by hand eats hours.


Perfai Security does that testing for you. Just enter your app URL. Our agents sign up their own test accounts, then test thousands of permission combos across roles and actions. You get a pentest-style report with proof for every issue. We also run drift detection, so new gaps get caught as your app changes.

Great idea! Quick question: how do we ensure this fix doesn't break anything or cause a regression in the application?

Great question! This is exactly why we keep a human in the loop. Perfai suggests the fix, but your team reviews and applies it. Access control changes can break real user flows if applied blindly, so we never push changes to your app ourselves.


Each finding comes with proof of how we exploited it, so your developer knows exactly what to fix and why. After you apply the fix, just re-run the test. Perfai verifies the issue is gone and that your other permission checks still pass. Our drift detection also keeps testing as your app changes, so if a fix causes a new gap later, you'll catch it fast.

This is going to be huge as vibe coding takes off. Speed of building goes way up but security review doesn't keep pace. One prompt to find live vulnerabilities is a compelling pitch. What types of vulnerabilities are you catching most often?

Maker

 
Thank you! You nailed the gap. Building got 10x faster, security review didn't.

We test 80+ access control categories in total. The most common issues we catch:

Cross-tenant data leaks: OrgA reading OrgB's data through IDOR and BOLA gaps. This is the scariest one and shows up constantly in vibe-coded apps.


Broken role checks: A viewer or basic user doing admin actions, like deleting records or changing settings they shouldn't touch.


Same-tenant leaks: User1 seeing User2's private data inside the same org.

Unprotected APIs: The UI hides a button, but the API behind it accepts the request anyway. AI coding tools do this a lot.


So far we've tested 4,000+ apps, found 28,000+ vulnerabilities, and saved teams $27M in bug
bounty payouts. Every finding comes with proof in a pentest-style report, and drift detection keeps testing as you ship.

 28,000 vulnerabilities across 4,000 apps is a scary hit rate. The cross-tenant data leak one especially, that's the kind of bug that ends companies. Makes sense that it shows up more with AI-generated code since the model doesn't think about multi-tenancy by default. Nice work.

Congrats on the launch this is such a timely product given how fast vibe coding tools are scaling without security guardrails. Curious, when your platform finds and fixes vulnerabilities automatically how do you handle edge cases where a fix could break existing app logic? Is there a approval step before changes go live?

Maker

 

Thank you! And great question. Yes, there's always an approval step. We never push changes to your app ourselves.


Here's the flow: Perfai finds the issue, shows you proof of how we exploited it, and writes a suggested fix with full context. Your developer (or your AI coding tool) reviews and applies it. If you built with Replit, Lovable, or Cursor, you can run "Fix all Perfai issues" and your coding agent applies the fixes, but you still review before deploying.


We keep a human in the loop on purpose. Access control changes can break real user flows if applied blindly, exactly the edge cases you're describing. After you apply a fix, just re-run the test. Perfai verifies the issue is gone and your other permission checks still pass. Drift detection also keeps testing as your app changes, so if a fix causes a new gap later, you'll catch it.

Congrats on the launch, team!

AI-coding tools let us build at lightning speed, but security usually gets left in the dust. Perfai fixing live vulnerabilities in vibe-coded apps with a single prompt is brilliant.

This bridges the gap between shipping fast and staying secure. Absolutely crushing it. Wishing you a huge success!

Thank you so much! You nailed it. Vibe coding is fast, but security can't keep up. That's exactly why we built Perfai.


Just enter your app URL and our agents test it like a real pentester would. You get a pentest-style report with proof for every finding. We also do drift detection, so every new release gets tested for new gaps.

The live vulnerabilities in vibe apps angle is useful, but I would want to know where the fix boundary is. Does Perfai mostly generate a patch suggestion, or can it prove the vulnerable path is no longer reachable after the one-prompt fix? That verification loop is where these tools usually get messy.

Maker

 
Here's the reply with the loop framing:


Great question! Perfai works in a simple loop: Test, Fix, Retest.


Test: enter your app URL and our agents test your live app like a real pentester. Fix: say "Fix all Perfai issues" or "Fix critical Perfai issues" in Replit, Lovable, or any code agent, and it instantly generates the fixes for you to review. Retest: say "run security" and Perfai retests your live app to confirm issues are fixed and nothing is broken.


So the proof is a real retest against your running app, not just a code diff. We also do drift detection, so every release gets tested for new gaps.


Every finding comes with proof in a pentest-style report. There's a free tier if you want to try it, and I'm happy to share a 50% discount code plus extra credits. Ping me if you need help onboarding!

Thank you! That's exactly the gap we're closing. Ship fast, stay secure.


Perfai works in a simple loop: Test, Fix, Retest. Enter your app URL and our agents test your live app like a real pentester. Then say "Fix all Perfai issues" in Replit, Lovable, or any code agent to generate the fixes. Say "run security" to retest and confirm nothing is broken. We also do drift detection, so every new release gets tested for new gaps.

For apps built on Lovable or Replit specifically, where the developer often doesn't have direct access to the underlying infrastructure or can't freely modify server-side auth logic, how does Perfai actually apply fixes? Those platforms have constraints on what you can change and where, curious whether the "1-prompt fix" works within those constraints or requires exporting the project first.

Maker

 


Great question! No export needed. The fixes work within the platform itself.


Perfai doesn't touch your infrastructure. When you say "Fix all Perfai issues" in Lovable or Replit, the platform's own AI agent generates the fixes in your app code, the same code you already own and can edit there. Most access control gaps in vibe-coded apps live in that app layer, like missing auth checks on API routes or client-side-only permission logic, so they're fixable right inside the platform.


After you review the fixes, say "run security" and Perfai retests your live app to confirm the issues are fixed and nothing is broken. Test, Fix, Retest.

vibe coded apps have a real security problem that nobody talks about enough. the same speed that lets you ship in hours also means access control and input validation are usually the last things anyone thinks about. autonomous fixing is the interesting part here though. most security scanners find vulnerabilities and then leave you to figure out the fix. does perfai actually apply the fix to the codebase directly or does it generate a patch you review first before anything changes?

Maker

 you've put your finger on the part we care about most 🙏. You're right, most scanners dump a vuln list and leave you to figure out the fix. That's exactly where Perfai Security is different.

To answer your question, no, we never write to your code behind your back. The Fix Agent figures out exactly what needs to change, whether that's a missing authorization check, or a policy that needs enforcing, then sends the suggested fix, together with the full vulnerability context, to the AI coding assistant you're already using (Cursor, Claude Code, Replit, Copilot, or Windsurf). You review it, apply it when you're happy, and nothing changes until you say so.


Perfai then re-runs the exact exploit to make sure the issue is actually closed. We don't consider a vulnerability fixed until we've verified it.

Developer in the loop by design.
