No lock-in
We don’t resell tools or push a favourite. Everything we build stays with you.
[ Why tool-agnostic ]
Choose the tool for your product, not for us
Plenty of test suites are abandoned because they were built in the wrong tool: a language the team doesn’t use, a framework that can’t reach Safari, or a load tool nobody can read. We start with your product, your stack and the people who will keep the tests running, then recommend what fits and prove it on your real app before you commit.
The right fit for your team
We match the tool to your stack, languages and the people who will maintain the tests.
Work in what you already have
Already have a suite? We pick it up, stabilise it and grow it.
Proof before you commit
We try the tool on your real app first, so the choice is based on results.
[ 6 tools we specialise in ]
Deep experience in the tools that matter most
Four for functional automation and two for load testing. For each: what we do, who it suits, the languages it supports and an honest note on its limits.
Fast, reliable end-to-end tests across Chromium, Firefox and WebKit (Safari), with API testing built in.
What we do
- New Playwright frameworks from scratch
- Page objects, fixtures and test data set-up
- API and UI tests in one suite
- Traces, videos and reports for every failure
Best for
Modern web apps and single-page apps · Cross-browser coverage including Safari · Teams that want fast, parallel runs
Languages
TypeScript, JavaScript, Python, Java, C#
Choose it for most new web automation projects.Watch out: Very old browsers such as Internet Explorer are not supported.
The long-standing standard for browser automation, with the widest language and browser support and a huge ecosystem.
What we do
- Selenium 4 frameworks with WebDriver and Grid
- Taking over and stabilising existing suites
- Fixing flaky tests and slow runs
- Parallel runs on Grid or a device cloud
Best for
Enterprise apps and older browsers · Java and C# teams · Large existing Selenium suites
Languages
Java, C#, Python, JavaScript, Ruby
Choose it when your team works in Java or C#, or you need the broadest browser support.Watch out: Needs more set-up and care than newer tools to stay fast and stable.
One open-source tool for native, hybrid and mobile web apps on both iOS and Android, on emulators and real devices.
What we do
- Appium 2 frameworks with UiAutomator2 and XCUITest drivers
- Gestures, permissions, deep links and push notifications
- Runs on BrowserStack, Sauce Labs or your own devices
- Shared steps across iOS and Android
Best for
iOS and Android apps from one test suite · Native, hybrid and React Native or Flutter apps · Real-device runs on device clouds
Languages
Java, JavaScript, Python, C#, Ruby
Choose it when you want one suite for both mobile platforms.Watch out: Slower than native tools such as Espresso or XCUITest for very large suites.
A developer-friendly tool that runs in the browser, with instant feedback, time-travel debugging and easy component testing.
What we do
- Cypress frameworks and custom commands
- Component tests for React, Vue and Angular
- Network stubbing and test data control
- Cypress Cloud or CI parallel runs
Best for
JavaScript and TypeScript front-end teams · Component and end-to-end tests together · Fast feedback while coding
Languages
JavaScript, TypeScript
Choose it when front-end developers will write and own most tests.Watch out: Limited multi-tab and cross-origin support, and Safari is still experimental.
Open-source, widely used and good for web, API and database load. We build maintainable JMeter test plans and run them at scale in the cloud.
What we do
- Test plans from your real traffic
- Correlation, parameters and realistic data
- Distributed runs on cloud load generators
- Grafana and InfluxDB dashboards
Best for
Web, API, SOAP and database load · Teams that prefer a visual test builder · Large, distributed load tests
Languages
Visual builder, with Groovy for scripting
Choose it for broad protocol support and teams who prefer a visual tool.Watch out: Test plans can get hard to review in code; we keep them modular.
Load tests written as code in JavaScript, easy to keep in your repository and run in your CI pipeline on every build.
What we do
- k6 scripts kept in your repository
- Thresholds that pass or fail the build
- Cloud or distributed runs at scale
- Grafana dashboards and trend reports
Best for
Developer-led teams and CI pipelines · API and microservice load · Performance budgets on every build
Languages
JavaScript, TypeScript
Choose it when you want performance tests to live with your code.Watch out: Browser-level testing is newer; most k6 tests work at the API level.

[ Tool migration ]
Moving to a better-fit tool, safely
When a tool is holding you back, we move your tests across in priority order, with both suites running until the new one is proven.
SeleniumPlaywrightFaster, less flaky runs and built-in Safari coverage.
ProtractorPlaywright or CypressProtractor is no longer maintained.
CypressPlaywrightMulti-tab, multi-origin and Safari coverage.
LoadRunnerJMeter or k6Lower licence costs and tests your team can own.
JMeterk6Load tests kept as code and run in CI.
Manual suitesAny of the aboveYour most repeated checks, automated first.
How a migration runs
- 01Review the current suite and agree what to keep
- 02Prove the new tool on your riskiest journeys
- 03Move tests in priority order, running both suites side by side
- 04Switch CI over and retire the old suite
