Comparing Browserstack and SauceLabs

Both platforms offer robust testing capabilities, but selecting the right one requires careful consideration of specific needs and constraints.

Budgetary Constraints

For many organizations, the cost of services significantly influences decisions. At first glance, BrowserStack's Freelancer plan, priced at $12.50 per month, seems reasonable. However, its scope may not fully address the comprehensive testing demands of an expanding startup. The Desktop & Mobile plan, at $39 per month, offers a more encompassing testing environment, spanning both desktop and mobile platforms.

And while Sauce Labs’ Free plan’s 2,000 credits per week are enticing, the plan may prove inadequate for startups with rigorous testing needs. Their Monthly plan, priced slightly higher at $50 per month, grants a substantial 25,000 credits, potentially aligning more closely with the expected testing frequency of a growing company.

Specific Testing Needs

There’s no such thing as a one-size-fits-all solution; choosing a tool requires careful consideration of a given tool’s feature set and whether it can meet your needs. For companies grappling with the following issues, the decision may involve answering these questions:

  • Geolocation Testing: Does the application deliver content tailored to the user's location?

BrowserStack offers geolocation testing in its Team plan and higher tiers.

Sauce Labs doesn't provide clear information about geolocation testing in its listed plans.

  • Mobile App Testing: Is there a need to develop a mobile version of the application?

BrowserStack supports testing on real iOS & Android devices within its Desktop & Mobile plan.

Sauce Labs includes mobile testing, but further investigation would be needed to understand the specific devices and configurations available.

  • Collaborative Debugging: Is team collaboration on debugging sessions a common practice?

BrowserStack includes this feature in its Team package.

Sauce Labs doesn't say whether collaborative debugging is part of its offerings.

The Verdict

In the startup realm, decisions are seldom easily cut-and-dried. Theoretically, BrowserStack's Desktop & Mobile plan, priced at $39 per month, aligns seamlessly with the prerequisites of geolocation and mobile app testing. The prospect of upgrading to the Team plan for enhanced collaborative debugging makes it even more appealing. 

However, it’s wise to proceed with caution. Both platforms offer trial periods, and you should take advantage of that. Hands-on experience often reveals nuances that mere specifications can’t provide.

The Visual Testing Wildcard: Meticulous

Meticulous for visual regression testing

Although BrowserStack and Sauce Labs may be among the best options for cloud-based device testing, there are many other aspects of visual testing to consider. For instance, nearly all tools on the market — even no-code tools — require some amount of maintenance. As long as your test suite requires you to configure tests in some capacity, maintenance is inevitable.

The only way of solving this is by having instrumentation be the only aspect of configuration — enter Meticulous. This tool requires only that you install a simple Javascript snippet, after which Meticulous will record real user sessions. Then it analyzes screenshots with pixel depth, to catch any and all visual discrepancies.

All of this — combined with additional features found within Meticulous — lays the foundation for an efficient visual regression testing tool.

What’s the Right Choice for You?

Both BrowserStack and Sauce Labs present a suite of tools tailored to streamline and elevate the testing experience for developers and QA professionals. However, picking one over the other requires a thorough understanding of their features, similarities, and distinctions.

Meticulous is a tool for software engineers to catch visual regressions in web applications without writing or maintaining UI tests.

Inject the Meticulous snippet onto production or staging and dev environments. This snippet records user sessions by collecting clickstream and network data. When you post a pull request, Meticulous selects a subset of recorded sessions which are relevant and simulates these against the frontend of your application. Meticulous takes screenshots at key points and detects any visual differences. It posts those diffs in a comment for you to inspect in a few seconds. Meticulous automatically updates the baseline images after you merge your PR. This eliminates the setup and maintenance burden of UI testing.

Meticulous isolates the frontend code by mocking out all network calls, using the previously recorded network responses. This means Meticulous never causes side effects and you don’t need a staging environment.
