Challenges of testing with Mabl

As you scale your testing needs, you may start to notice that Mabl’s strengths come with a few constraints. These aren’t deal-breakers for every team, but they can slow you down when your test suite grows, your product gets more complex, or your release cycles tighten. We’ve heard many teams describe the same patterns, so we want to walk you through the areas where Mabl tends to struggle.

You might relate to some of these:

• Limited flexibility in complex test logic: Mabl’s low-code interface is friendly at first, but once you need custom flows, conditional logic, or deeper assertions, the visual editor feels restrictive. You spend more time working around the UI than actually building tests.
• Scaling costs grow quickly: As your team expands test coverage, execution hours can jump significantly. Many users feel they must trim tests or avoid frequent runs to stay within budget, which defeats the purpose of continuous testing.
• Mobile support gaps: Mabl is primarily built for web automation. If your team relies on mobile apps or uses a hybrid testing strategy, you will likely need another tool to fill the gap.
• Opaque AI behavior: While Mabl’s auto-healing is helpful, it sometimes updates locators or test steps in ways that are hard to audit. This can introduce uncertainty—especially in regulated industries where test traceability matters.
• Longer onboarding for technical teams: Engineers who prefer full control often find the abstraction limits their ability to debug or extend tests. This creates a split workflow between engineers and QA specialists, slowing delivery.
• Limited integration depth: Although Mabl offers key integrations, teams handling enterprise-scale pipelines sometimes struggle connecting Mabl seamlessly into multi-stage CI/CD flows.

To make things easier to compare, here’s a quick overview of where Mabl tends to fall short:

When these challenges stack up, teams naturally begin looking for alternatives that balance ease of use with deeper customization, richer AI capabilities, and stronger cross-platform coverage. That’s where the next set of tools comes in.

5. Leapwork

Leapwork is a no-code automation platform built around visual workflows. Instead of writing scripts, you connect blocks in a flowchart-style canvas to describe how users move through your application. If your organization wants business users, QA analysts, and subject-matter experts to participate in automation without touching code, Leapwork speaks directly to that need.

Rather than thinking in terms of frameworks and libraries, you map out processes step by step: open this page, click that button, verify this value, and so on. Over time, these flows become reusable building blocks that reflect the way your business actually operates, not just how the UI is implemented.

Where Leapwork tends to work well:

• Visual flow-based design: You build tests as visual diagrams, which makes them easier to read and explain to non-technical stakeholders.
• No-code collaboration: Business users can help design and review flows, so QA is not limited to a small group of automation engineers.
• Support beyond web: Leapwork can automate web, desktop, and some legacy or packaged applications, which is useful in enterprise environments.
• Centralized scheduling and execution: You can schedule, trigger, and monitor test runs from a unified control center.
• Built-in monitoring and reporting: Dashboards and logs help you understand where flows fail and how stable they are over time.

However, the same no-code philosophy that makes Leapwork accessible can also introduce constraints—especially if your team is more engineering-driven or your application has highly dynamic behavior.

Key challenges to be aware of:

• Complex flows can become hard to manage: As scenarios grow, diagrams can get crowded and harder to reason about than a well-structured codebase.
• Less flexibility for advanced logic: Very specific conditions, data manipulations, or edge cases might require creative workarounds inside the visual model.
• Enterprise-focused pricing: Leapwork is typically positioned toward larger organizations, which may put it out of reach for smaller teams or startups.
