About Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability. Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort. Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in. Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens. The result: ship faster, with confidence.

		Pros & Cons from Real Users Pros LambdaTest brings with it solutions for testing our application in different clients, in a simple way, thus relieving the work of developers. It offers solutions through the SSH Tunnel functionality, in addition to an optimal integration with Trello that allowed us to organize our work management and unify functions. We adapt much better to Lambdatest than to other platforms because they are easier to use and even cheaper. It automates functions that previously developers had to do manually, which was a huge job to discover errors or why the operation is not correct, with this platform it is possible to analyze what may be coming out more or do tests where you want and evaluate the application in detail so that everything works solidly. It also has a solution that no one else offers, which is a full-page clipping, with this we have been able to visualize the errors more clearly and we have been able to find accurate solutions to the problems, together with this we have adapted our application to various clients and now it works more smoothly. - Integrates with popular CI/CD and Project management tools - Responsive support team available 24/7 - Quick updates. - Extensive catalogue of 2000+ real browsers and operating systems. - Provides amazing tools for responsive testing LambdaTest LT Browser for Mobile responsive testing across 50+ pre-built viewports. - Selenium Automation Testing on cloud grid for desktop & mobile browsers. Provides effortless local testing through the Lambda Tunnel. Share automation test reports and record videos of test sessions. Extensive range of 2000+ real browsers and OS to test on. The support docs are easy to understand, and the product is easy to configure and get started with. We can compare mobile website view side by side in LT Browser. Plus, we can add custom devices as well. Geolocation testing is a plus. Easy integration with JIRA and more project management tools. Cons It has been difficult to manage some web drivers, as well as to correctly adapt our tests in the Safari browser, we have tried to do it on certain occasions, and we could not get it to run properly. The platform can have a little delay, it becomes slow, and it is tedious to work in this way, running the tests with the slowness of the platform becomes complicated, finding a more fluid platform would give us a greater scope for our tests. Having mobile application tests would be useful for our development, since we adapt quite well in the LambdaTest function and being able to adapt it to mobile application development would be a plus for our work. We haven't faced any issues for now, its quite user friendly and up to our expectations . Would be great to add more devices for Responsive testing! Would be great if they add native application testing in their cloud ecosystem. Yet to get native app testing. But, heard somewhere, they are going to add that soon.
