Who it is for

Sounds familiar?

For product teams, agencies and companies before a launch.

  • Every release breaks something that used to work.
  • Nobody checked the site on real phones and browsers.
  • The accessibility deadline is close and there is no report.
  • The new AI feature gives wrong or unsafe answers.

What we do

10 ways we help

  • Manual & Exploratory Testing

    Features, scenarios and regression: did anything old break?

  • Test Automation

    Automated tests with Playwright, Cypress and Appium, built into CI.

  • API Testing

    Checks of integrations and APIs.

  • Performance & Load Testing

    Will the site or service survive the traffic? With k6 and JMeter.

  • Security Testing

    OWASP Top 10 checks, scanning and organising a penetration test.

  • Accessibility Testing

    Checks against WCAG 2.2 and the EAA, with a report and fixes.

  • Mobile & Cross-Browser Testing

    Real devices, OS versions and browsers.

  • Localization Testing

    Every language version: texts, date and currency formats, layout.

  • AI & LLM Testing

    Answer quality, hallucinations and resistance to prompt injection.

  • QA Audit & QA as a Service

    An audit of your quality process, or a dedicated tester in your team.

How we work

From first call to running.

  1. 01

    Discover

    One call and one written brief. We tell you what to build, what to skip and what it costs.
  2. 02

    Design

    A clickable design in your brand, tested on real screens before any code.
  3. 03

    Build

    Weekly releases you can open in the browser, not status reports.
  4. 04

    Launch

    Legal pages, speed, accessibility and tracking are checked before go-live.
  5. 05

    Support

    EU hosting, updates, backups and a support contract with fixed response times.

What you get

Results, not activity.

  • A clear report

    What is broken, how bad it is and how to fix it, in order of priority.

  • Tests that keep running

    Automated tests run on every release, not once.

  • Accessibility on paper

    A report you can show to customers and authorities.

  • Safer AI features

    Known weak spots of your AI feature tested before users find them.

We pick tools for your case, not the other way round. EU hosting by default.

FAQ

Questions we hear often.

Do you test products built by other agencies?
Yes. Most audits are for products we did not build.
Can you also fix what you find?
Yes, our development team can fix the findings, or your team fixes them and we test again.
What does an AI feature test cover?
Answer quality on your real questions, made-up answers, attempts to make the assistant break its rules, and leaks of data it should not show.
