Slow performance at times

Software Tester

As it is cloud based so it is very slow making it difficult to use sometimes ,also we have very limited control over hardware.

QA Tester Lead

It is still too slow in performance when trying to test apps.

48% of reviewers feel negative about Performance and Speed. Reviewers indicate that LambdaTest can be slow, particularly when uploading files, running tests on real devices, or during peak usage times. Users say delays in UI response, environment deployment, and livestreaming device footage can hinder productivity. Some mention that performance inconsistencies are more noticeable with large test suites or when network bandwidth is limited. They find that these speed issues can make the platform less efficient for time-sensitive testing tasks.

Occasional bugs and glitches

QA Engineer

There were a few stability issues while using simulators and we expressed the concern to the support team.

48% of reviewers feel negative about Bugs and Issues. Some users report encountering occasional bugs, glitches, or stability problems that can disrupt testing sessions or require technical support. Reviewers indicate that live sessions may sometimes lag, disconnect, or experience minor technical hiccups, especially when using emulators or during high-traffic periods. They mention that these issues can impact efficiency and may necessitate additional troubleshooting, which can be frustrating when working under tight deadlines or with complex testing scenarios.

High and confusing pricing

AI Engineer

Pricing feels opaque and too many AI agent products makes it hard to know what is included per tier.

Programmer

The pricing got more difficult and the free options have been dumped in to as less as it is not possible to test things anymore, thus you are forced to get a subscription...

39% of reviewers feel negative about Pricing. Users think LambdaTest’s paid plans are expensive, especially for small teams, freelancers, or startups. Reviewers mention that essential features are often locked behind paywalls, and the free trial or plan offers limited functionality and usage time.

Lead, Full Stack Developer

AI is how it brings test management, automation, bug tracking, and browser/device testing into one unified platform.

The gap between listed devices and what can actually be launched reduced confidence in using the platform for scheduled validation or release work. While basic sessions and recording are straightforward to use, reliability of real devices has not met expectations, so it has been difficult to depend on.

It provided end to end testing in one platform including performance, API, mobile and database testing.

Sr. Software engineer

With improved support for native OS-level features like biometrics, social authentication, and push notifications, it would be an excellent end-to-end mobile testing solution.

I was looking for a tool where we can conduct our cross browser and multi device testing where Lambdatest not just provided variety of devices but helped us resolving issues that we had in our application and services.

Testing biometric authentication (Face ID / Fingerprint), social login flows, and push notifications is not fully supported or realistic on cloud devices, which can block complete end-to-end validation for React Native apps.

We frequently encounter “Device Not Available,” Because we rely on manual testing across specific devices for global clients, predictable access is critical.

Senior Software Engineer

I especially like the ease of being able to test our sites in a multitude of different browsers and operating systems without having to have the actual systems around.

QA Enginner

The test execution time can be slower especially when running  complex  tests on multiple browser in parallel. while the platform offers great browser support, occasional compatibility issues with newer browser version.

It simplifies test management and automation while providing reliable cross-browser and device testing.

its positive mostly as from a tester perspective we need various type of devices to test our apps and lambdatest help me to get those and do my stuff without spending money on the devices

The AI-driven features improve efficiency and reduce repetitive tasks, allowing the team to focus on higher-value work.

Head of QA

I love that it simplifies the work and allows all the team members to efficiently build cross-environment-compatible applications.

Additionally, performance can occasionally slow down when running large batches of tests simultaneously, though this hasn’t significantly impacted overall productivity.

LambdaTest is a solid platform for testing React Native apps across multiple devices, OS versions, and screen sizes.

Some features still feel limited, and the AI-generated tests sometimes require manual adjustments to better fit specific scenarios.

Sr. Manager

Helps catch compatibility issues early by letting you run the same link on different environments.

Developer

We have a product and provide integration with Lambdatest, so user can run their test cases on Lambdatest and can use all the different types of browsers with different configurations.

TestMu AI is a practical solution that helps reduce the time spent on repetitive testing tasks.

During the trial the platform looked promising, but in regular use real device availability has been inconsistent, especially for new iPhones and Ultra devices.

The tool has a large support matrix for browsers (current browsers all the way to legacy) and operating systems (desktop and mobile).

Senior Test Specialist

LambdaTest supports and provide simplest configuration to run cross-browser testing platform with a wide range of features designed to streamline the testing process.

Senior QA Manager

It helps speed up automated tests, provides manual testing across a variety of browsers/operating systems and their testu conference is an amazing gathering that provides networking and learning opportunities.

Testing across multiple browsers, OS versions, and real devices is a huge benefit, especially for teams trying to streamline their QA processes. While it is generally reliable, there is sometimes lag in a live test environment, and concurrency is limited on lower-tier plans to slow down workflows.

What impressed me the most about LambdaTest is the sheer variety of browsers and devices it offers for testing without needing to maintain anything on my side.

New iPhones and Ultra devices are frequently unavailable or show “Device Not Available,” sometimes for long periods.

Design Director

I love that you can just spin up an instance real quick, like, I need Windows 7 with a particular IE version and boom, you're in the past.

The intuitive UI, strong integration with CI/CD pipelines, and collaborative tools enhance productivity. While there’s room for improvement in free-tier performance and real device availability, the platform’s strengths, such as detailed reporting and responsive support, make it a valuable tool for QA teams and developers.

.NET Developer

This tool will allow me to test in different browsers and at different resolutions to achieve the best results, ensuring client satisfaction.

They took multiple tries to even simply explain their Multi-Device offering to me, and I've had different agents give me different information.

It’s made our workflow more efficient, and with a few UI improvements and advanced simulation features, it could become a near-perfect tool for front-end testing teams.
