    One day, I needed to test a specific issue that was occurring only on Pixel phones. I turned to LambdaTest, quickly identified the problem, and was able to fix it. There hasn't been a situation where I felt LambdaTest didn't help, it's my go-to solution for testing, as it solves many problems.

    I still have some issues, especially with color integration between the style guide and also project. When we update the colors, it's not automatically sync to every project. Aside from that, zeplin solves my problem for hand-off design from design to developer. I set zeplin is source of truth design file

    Pros
    TestMu AI
    • Very accessible as multiple users can be added in each subscription
    • Very reliable as it is very close to the actual device when it comes to operating system and version behavior
    • There are a lot of options for devices and browsers that users can choose from when it comes to emulating and testing

    Zeplin
    • Ease in automatically building design style guides, saving time that might be spent on building style guides in another tool (such as InDesign).
    • Users can use Mac, PC, or web versions of this app to collaborate on a single project, enabling us to work with a wider pool of contractors.
    • Accelerates the design-to-development workflow, as it’s very easy to import Sketch or Photoshop files through plug-ins, and HTML/CSS codes are automatically created based on designs.
    • Provides cross-platform specifications for web, iOS, and Android, which can save developers time in figuring out specifications beyond the “main platform" on their own.

    Cons
    TestMu AI
    • More real devices should be added like I have Samsung mobile but it was not in the list
    • It takes time in checking the link on LambdaTest if we compare with real mobiles
    • Sometimes exact results are not matching as from real mobiles

    • The uploading and syncing of assets is great for sketch and photoshop but we use illustrator and that can be cumbersome/tedious at times.
    • There are certain elements that have been a bit confusing to navigate at times, but for the most part, it's pretty user-friendly
    • More integrations

    The reason i have given the 10 points becasue the problem LambdaTest solves is providing access to all devices in one place, allowing developers to identify the same errors they would encounter on real devices. This makes life much easier, especially for developers who regularly face cross-device functionality issues. It's a big plus point that positions LambdaTest as an all-in-one solution.

    Because of the ease of use of the platform, we just save a lot of time and effort with this as its a feature rich solution, we just need to upload app binary once and for everytime we need to test on a different device we can just directly install that binary on the device without the pain of reupload.

    Zeplin's component management and style guide help us to be consistent across whole product and it so easy to use for non-technical person. It is now easy to collaboration for designes between different teams like stackholders, product owner, UI/UX, developers and testers. Now there is only one point of reference is Zeplin so it is so easy to get details without asking designer or developer again and again.

    The customer support team is very active and cooperative. Once, I contacted them in their off timings because of an issue, I got an instant reply from the executive and he resolved the issue very efficiently. This is why we have been using LambdaTest for more than two years. It is best suited for us.

    Zeplin has classic support with a chat from the website. It's working fine, and we're also getting the support needed when needed. However, Zeplin is very good at closing the incidents and moving on. It was a while ago we had a case with their support so that it might have improved since then.

    While BrowserStack is also a well-established platform, we found LambdaTest to offer similar and even better features at reasonable pricing. LambdaTest is more cost-effective than BrowserStack. LambdaTest provides a free forever plan, while BrowserStack does not. Even manual testing plans are better priced than BrowserStack’s. In terms of UI and onboarding, we found LambdaTest more user-friendly as well.

    Zeplin is great to inspect and share user interfaces, specifications and assets, perfect for developers. Tools like InVision and Marvel are much better to create prototypes for both developers, coworkers and even stakeholders, but they don't have this kind of feature (inspection) as Zeplin does. So each of them can be used for different purposes, offering different approaches to share and interact with layouts for apps and websites.

    Return on Investment
    TestMu AI
    • Automation testing has a bit of a learning curve
    • Lack of real device keep that bug in your head if not on the website.
    • Need to wait for a while for a new OS or browser version on the contrary of immediate availability in case of owning a lab

    • Development time has reduced as the design updates are communicated in real time to developers and they don't have to write the boilerplate code as it's already generated.
    • Employee engagement has improved as every stakeholder is aware about the design changes from the beginning and can give their inputs.
    • Designers save a lot of time as they don't to explicitly communicate when the update or publish their designs and also it just takes a couple of clicks to publish their designs. Also, lot of rework is saved as every stakeholder is involved right from the beginning.
