You send the app
Send the URL, test account, user roles, sensitive flows, and launch context. We do not need code access by default.
AI scans and automated tools miss the dangerous issues. We combine AI with real human pentesters to find what actually matters, before your users do.

AI can scan patterns. A specialist reviews your actual app: what users can access, what flows can be abused, what endpoints trust the frontend, and what could leak after launch.
Send the URL, test account, user roles, sensitive flows, and launch context. We do not need code access by default.
We use automated checks for coverage, but the review is human-led. The risky flows are tested manually, like a user and like an attacker.
Every meaningful issue is validated and explained with evidence, severity, business impact, reproduction notes, and remediation guidance.
Every review is supported by automated checks, but findings are human-reviewed before they reach you.
Login flows, access control, role leaks, broken authorization.
Unsafe inputs, weak validation, missing checks, exposed endpoints.
Leaked keys, bad defaults, exposed environments, unsafe production setup.
User actions that should not be possible, broken edge cases, payment and state-flow issues.
Stripe, auth providers, storage, third-party services, and risky connection points.
Unsafe assumptions, copied insecure patterns, and logic mistakes hidden behind 'it works'.

WithDoneBetter is led by Vinicius Martin, a software engineer with 10+ years of experience building production apps, APIs, checkout flows, dashboards and AI-assisted products.
I started WithDoneBetter to help small teams ship faster without trusting only automated scanners or AI-generated security assumptions.
The $5 scan is delivered by email within 24 hours. The $199 Human Launch Pentest starts with payment and intake, then a complete fix-ready report is delivered by email in 5 business days.
Fast automated scan for common launch risks, delivered by email within 24 hours.
We run a surface-level scan over your app to catch obvious security issues before they become production problems. After submission, watch your inbox and spam or promotions folder for the result.
Manual testing, exploit reproduction, business logic review or full pentest report.
Best for quick pre-launch checks.
Start with payment, then complete the intake form. A human specialist reviews your small app before launch and delivers a complete fix-ready report by email in 5 business days.
After checkout, watch your inbox and spam or promotions folder for intake and report emails. The review validates what matters and explains what to fix first.
Delivered in 5 business days.
For MVPs, SaaS apps, client portals, internal tools and AI-built apps.
For larger apps, sensitive systems and teams that need deeper coverage.
Built for production apps with more complex flows, larger attack surfaces, sensitive customer data or compliance requirements.
Recommended for fintech, health, marketplaces, enterprise tools or apps handling sensitive data.

Start with the $5 scan if you want a quick automated check. Choose the $199 Human Launch Pentest if you are about to ship and need a human to verify what actually matters.
Pick a time and we can quickly see if your app is ready for the $199 Human Launch Pentest or a custom scope.
If your app is live, close to launch, or heading into a demo, yes. This is for founders and small teams who want to catch security issues before users, clients, or enterprise buyers do.
The scan is automated only: it can catch common patterns and give you a starting point. The $199 Human Launch Pentest adds human testing, authenticated and unauthenticated flow review, proof, business impact, remediation guidance, and a complete report.
Most firms are built for larger contracts, bigger teams, and slower processes. We use a tighter model: AI-assisted checks for speed, plus human specialist validation for what is real and worth fixing.
No. Just a URL. We work from the outside, like an attacker would, which means you can start immediately without handing over your codebase.
Free scanners catch part of the obvious stuff. They usually do not tell you what is real, what matters first, or how an attacker could chain issues together. We use automation for speed, then human validation to confirm what is actually risky.
The scan is the fastest automated pass. The $199 Human Launch Pentest is delivered in 5 business days, depending on app access and flow complexity.
Every finding is written in plain English with severity, impact, and what to fix first. When useful, we also include fix-ready notes and a copy-paste prompt for your AI tool so your team can move faster.
