Your usersshouldn't beyour testers.
We're engineers, not checkbox testers. For 11 years Relivox Labs has engineered quality into web apps, mobile apps and APIs: we break your product the way real users will, then hand you a Product Health Report that shows exactly what to fix before launch.
- Engineering-led QA
- Results in days, not weeks
- 100% independent
Every bug you ship sends a message.
It tells your customers you didn't check. Most teams find out what's broken from angry emails, refund requests and churn. We make sure you find out first.
Developers can't see their own blind spots
The people who built it know how it's supposed to work, so they test the happy path. Your users won't.
One broken flow quietly kills revenue
A checkout that freezes on one phone, a form that rejects a valid email. Users don't report it. They just leave.
One-star reviews outlive your hotfix
You can patch a bug in an hour. A bad first impression in the App Store stays there for months.
Fixing after launch costs the most
A bug found in production means support tickets, emergency releases and a team pulled off the roadmap.
Scan your site. Get a score in seconds.
Vox runs 25+ automated checks across security, performance, SEO, accessibility and reliability, then shows you exactly what's broken. Free, no sign-up.
We only scan public pages. Nothing is stored.
Everything gets tested. Nothing gets assumed.
UI/UX & Usability Testing
Your analytics show what users do. We show you why. We review every screen for visual bugs, broken layouts, confusing flows and friction, and score usability with the System Usability Scale (SUS).
Functional Testing
Every button, flow and business rule checked against how it's meant to work.
Mobile App Testing
iOS and Android on real devices, screen sizes, OS versions and bad networks.
Web App & Website QA
SaaS platforms, dashboards, e-commerce and marketing sites, end to end.
Cross-Browser & Compatibility
Chrome, Safari, Firefox, Edge. Desktop, tablet, mobile. No surprises.
Performance & Load
Speed, stability and how your product behaves when traffic actually shows up.
Security Testing
OWASP-aligned checks for the vulnerabilities attackers look for first.
API Testing
Contracts, edge cases, error handling and data integrity behind the screen.
Accessibility (WCAG)
Make sure everyone can use your product, and stay on the right side of compliance.
Regression & Release QA
New features shouldn't break old ones. We verify every release before it ships.
Form & Conversion Audit
Find the friction in sign-ups, checkouts and forms that quietly costs you leads.
Test Automation
Repeatable automated suites for the flows you can't afford to re-check by hand.
Exploratory Testing
Experienced testers going off-script to break things the way real users do.
We engineer every layer.
Bugs don't only live on the screen. As quality engineers we test the whole stack, from the pixel your user taps to the server that answers, so nothing slips through the cracks.
From 'is it ready?' to 'it's ready.'
An engineering process, not guesswork. Refined over 11 years of testing real products for real teams.
Discover
We learn your product, your users and what 'done' means to you. You share a link or a build. No code access required.
Strategy
A test plan mapped to your riskiest flows and to ISO/IEC 25010 quality characteristics, so nothing important is left to chance.
Execute
Manual, exploratory and automated testing across real devices, browsers and conditions. Every issue is captured with evidence.
Report
You receive the Product Health Report: severity-ranked issues, steps to reproduce, screenshots, and clear recommendations.
Retest & Sign-off
Once your team fixes the issues, we verify every fix and confirm nothing else broke. Then you launch with confidence.
We don't just find bugs. We hand you the fix map.
Most testing ends with a messy spreadsheet. Ours ends with the Product Health Report™: a clear, professional document your developers, managers and investors can all understand.

Your team built it. We prove it works.
Asking developers to test their own work is like proofreading your own essay. You read what you meant to write, not what's on the page.

SaaS Teams
Ship features faster without letting regressions reach paying customers.

White-label QA so every client handoff is polished and bug-free.
