UbserveThree steps between you and a safe launch.
1. Paste your app URL
No setup. No secrets. Just your URL. We handle the rest.
2. We scan your app
We scan your endpoints, Supabase configuration, and exposed keys - probe every surface a real hacker would.
3. Get your security report
Receive a clear, honest report with AI-generated fixes ready to paste into your code.
Stripe secret key is hardcoded in frontend and visible in browser source.
The mistakes vibe-coded apps usually ship with.
The free scan checks what the public internet can already see. The full audit goes deeper into Supabase, Firebase, GitHub, auth flows, and payment-sensitive paths.
Exposed keys in frontend code
AI-built apps often ship Supabase anon keys, payment keys, AI provider keys, or secret-looking tokens inside public JavaScript bundles.
The URL scan inspects reachable HTML and JavaScript bundles, then separates expected public keys from keys that need urgent rotation.
Missing RLS and weak database rules
A public Supabase key is normal. It becomes dangerous when Row Level Security is missing, too broad, or not tied to the logged-in user.
The full audit checks Supabase and Firebase access paths so you can confirm database records are not readable by strangers.
Public source maps
Production source maps can reveal original file names, routes, env names, frontend logic, and source snippets attackers can study.
Ubserve derives source map URLs from public bundles and flags maps that expose original source content.
Missing security headers
Without browser protection headers, users are easier to target with injected content, clickjacking, unsafe framing, or loose browser behavior.
We check CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, and related response headers.
Auth pages that can be cached
Login and password-reset screens should not be saved by browsers or proxies, especially on shared devices or synced browser profiles.
The scan probes login, signup, forgot-password, reset-password, and auth routes for a proper no-store cache policy.
Rate limits missing on sensitive routes
Password reset, login, signup, and public API routes become easier to spam, brute-force, or abuse when repeated requests are not slowed down.
Ubserve runs a gentle smoke test and looks for throttling signals like 429, Retry-After, or RateLimit headers.
Public API data exposure
A route that returns account, customer, admin, order, or token-like JSON without login can become a direct data leak.
We probe common API paths and only flag responses that look real and data-bearing, reducing noisy fallback-route false positives.
CORS that exposes real API responses
Permissive CORS on actual API responses can let other websites read data your backend should only expose to trusted origins.
The scanner now checks whether a wildcard CORS response looks like a real API before turning it into a finding.
Verbose production errors
Stack traces, framework internals, and file paths give attackers a map of your backend and dependencies.
Ubserve probes harmless error paths and flags responses that leak production debugging detail.
Everything you need before you go live.
Paste a domain and Ubserve checks the public app surface for exposed keys, source maps, unsafe headers, auth pages, and API signals.
This is what's already in your app.

“The Ubserve audit flagged 5 vulnerabilities in our app - including a critical database issue we had no idea existed.”
Common questions about app security audits.
What's the difference between the Ubserve scan and the Ubserve audit?
The free scan checks the public surface of your app: HTML, JavaScript bundles, exposed keys, source maps, security headers, SSL, auth page caching, rate-limit signals, CORS, and public API responses. The audit includes the scan, then adds Supabase or Firebase checks, GitHub repository scanning, authenticated test-account checks, and a full report with fix prompts.
What does Ubserve search for in the audit?
The audit covers exposed keys, public source maps, missing browser security headers, verbose production errors, auth page caching, weak rate-limit signals, public API data exposure, missing RLS, public buckets, Firebase database and storage exposure, GitHub secrets, risky auth code, dependency signals, and payment-sensitive access mistakes.
Is my code or credentials stored?
No. We never store your source code, API keys, database credentials, or Supabase access tokens. Credentials used during authenticated scans are used in memory and discarded immediately after the scan completes.
Do I need to be technical to use Ubserve?
No technical knowledge required. Every finding is explained in plain English, and every vulnerability comes with an AI-generated fix prompt you can paste directly into Cursor, Lovable, or Claude.
How long does a security scan take?
The free frontend scan completes in about 10 seconds. A full audit - covering your frontend, Supabase configuration, and GitHub - takes anywhere from 1 to 5 minutes. We prioritize speed so you can get results fast enough to keep shipping or go live without slowing down.
What is vibe coding and why does it create security risks?
Vibe coding means building apps with AI tools like Cursor, Bolt, Lovable, or Windsurf. These tools speed up development but frequently generate code with exposed API keys, missing authentication, and misconfigured databases - vulnerabilities attackers actively search for.
How is Ubserve different from other security tools?
Traditional security tools were built for engineering teams. Ubserve is built for vibecoders shipping real products with Cursor, Lovable, Bolt, Supabase, Firebase, and GitHub. It explains what attackers could do, shows the fix path, and gives prompts you can paste into your AI coding tool.
