What is platform testing?

Platform testing checks that your product works properly on every platform your users rely on: websites, iOS and Android apps, APIs, desktop software, cloud services and the databases underneath. Each platform has its own risks, so each needs its own checks.

Which platforms do you test?

Websites and web apps, mobile apps on iOS and Android, APIs and microservices, AI and LLM products, desktop software on Windows, macOS and Linux, cloud and SaaS products, and databases and data pipelines.

Do you test on real devices or emulators?

Both. Emulators and simulators give fast feedback during development. Before release we test on real devices, our own and on device clouds such as BrowserStack, Sauce Labs and LambdaTest, because real hardware behaves differently.

How do you choose which devices and browsers to test?

We start from your analytics and target markets, then cover the browsers, OS versions and devices that most of your users have, plus any you have promised to support. The coverage planner on this page gives you a first view.

Is Android testing different from iOS testing?

Yes. Android runs on thousands of devices from many makers, each with its own changes, so device coverage matters most. iOS has fewer devices but strict App Store rules and fast OS adoption, so review guidelines and new iOS versions matter most.

Can you help us pass App Store and Google Play review?

Yes. We check your app against Apple’s App Store review guidelines and Google Play policies before you submit, and test builds through TestFlight and Play pre-launch reports, so you avoid avoidable rejections.

Do you test responsive websites on mobile browsers?

Yes. Mobile web is tested on real phones and tablets in Safari and Chrome, not just by resizing a desktop browser, so touch, keyboards and viewport issues are caught.

Why test APIs separately from the app?

Because many problems start below the screen. Testing APIs directly catches wrong data, security gaps and breaking changes faster and earlier than UI testing can, and it keeps every app that uses them stable.

Can you test our web and mobile apps together?

Yes. We test shared journeys end to end across platforms, such as signing up on the web and continuing in the app, as well as what each platform does differently.

Do you test desktop applications?

Yes. We test installers, updates, permissions, files, printing and peripherals on the Windows, macOS and Linux versions you support.

How do you test cloud and SaaS products?

We focus on what makes SaaS different: one customer never seeing another’s data, plans and billing, upgrades without downtime, and integrations such as SSO and webhooks, on every release.

A platform map and device matrix, test plans per platform, bug reports with device and browser details, and a readiness report that shows clearly which platforms are ready to release.

Can platform testing be automated?

Much of it can. Stable journeys can run automatically across browsers and devices on every build, while new features and device-specific behaviour are still best checked by people.

How do we get started?

Book a call or send the form on this page. We start with a free one-week proof of concept on your most important platform, so you can see our bug reports before you commit.

Platform Testing Services

Your customers meet your product on a laptop browser, an Android phone, an iPad, a desktop app or another system calling your API. It has to work on all of them.

We test each platform for the way it really fails, on real devices, browsers and environments, and bring the results together in one plan, so you know exactly what is ready to release and where.

[ Why platform testing ]

Same product, different ways to fail

A checkout that works on Chrome can freeze in Safari. An Android update can break a screen that looked fine last week. An API change can quietly send wrong data to every app at once. Each platform brings its own risks, so testing has to change with it. We plan coverage around the platforms your users actually rely on, and test each one for the way it really breaks.

Every user, same experience

Customers don’t care which platform broke. They just see your brand fail. We check each one they use.

One plan, not six

A single coverage plan across web, mobile, APIs and data, so nothing is tested twice or missed.

Risks first

Each platform fails in its own way. We start with the risks that belong to yours.

Clear evidence per platform

Results broken down by platform, device and browser, so you know exactly what is ready.

[ 9 platforms we test ]

Every platform your users rely on

A short guide to each platform: what we check, when you need it and the risk we test first. Each one links to a detailed page.

Website Testing

Browsers & devices

View service

Your website or web app checked the way visitors really use it: on their browsers, screen sizes and connections, from the first page view to the last click.

What we check

Every key journey on Chrome, Safari, Edge and Firefox
Responsive layouts from small phones to wide screens
Forms, sign-in, search, checkout and payments
Page speed, broken links and basic accessibility

When you need it

Before a launch or redesign, and before every major release.

Top risk we test firstLayouts and journeys that break on one browser or screen size

Calls, low battery, poor signal and offline use
App store guidelines before you submit

When you need it

Before every store release, and whenever a new OS version ships.

[ How testing changes by platform ]

What breaks first, and what we always check

The same release can be safe on one platform and risky on another. This is how our focus shifts from platform to platform.

Platform	Biggest risk	What we always check
Website	Browser and screen-size differences	Real browsers, responsive layouts, speed
Mobile app	Device fragmentation and interruptions	Real devices, OS versions, store rules
Android	Thousands of devices and maker skins	Device matrix from your analytics
iOS	App Store review and fast OS adoption	Latest iOS versions, review guidelines
API	Breaking changes and wrong data	Contracts, auth, errors, timeouts
AI & LLM	Answers that change every time	Scored answers, guardrails, regression
Desktop	Installs, permissions and hardware	OS versions, user rights, updates
Cloud & SaaS	Tenant data and frequent releases	Isolation, billing, zero-downtime upgrades
Database	Silent data errors	Integrity, migrations, report accuracy
