What frameworks is Mod compatible with?

Mod is completely framework-agnostic. It is written in plain CSS and can be used with any front-end or full-stack framework that can import CSS files. This includes, but is not limited to, Next.js, Nuxt.js, Svelte/SvelteKit, Vue.js, React, Vite, Astro, Ruby on Rails, Django, Laravel, and plain HTML websites. Its utility-class approach integrates smoothly into any environment.

Does Mod include JavaScript for interactive components?

No, Mod is a CSS framework focused on styling, layout, and visual presentation. It provides the complete styles for interactive states (like hover, focus, active) for components such as dropdowns or modals. However, the actual interactive functionality (opening/closing, toggling) must be implemented using your chosen framework's JavaScript or a dedicated JavaScript library. This separation keeps Mod lightweight and flexible.

How customizable are the components and themes?

Mod is highly customizable. It is built using CSS custom properties (variables) for core design tokens like colors, fonts, spacing, and radii. You can easily override these variables in your own CSS to match your brand. Furthermore, the utility-class system allows you to modify individual components on the fly. The two included themes (light/dark) serve as excellent starting points that can be extended or completely altered.

What is the update policy for Mod?

Mod receives yearly updates as part of the CheatCode ecosystem. These updates ensure the component library stays current with modern design trends, accessibility standards, and best practices. This update policy provides a predictable maintenance cycle, giving developers confidence that the tool they are building with will be supported and improved over the long term without constant, breaking changes.

How does qtrl.ai ensure the AI doesn't make unpredictable changes?

qtrl is built on a principle of "permissioned autonomy." The AI does not make changes or execute tests without review and approval, unless explicitly configured to do so within strict rules you define. All AI-generated test scripts and modifications are presented for human review first. You maintain full visibility into every action the agent takes, ensuring there are no "black-box" decisions and you remain in complete control.

Can qtrl.ai work with our existing tools and CI/CD pipeline?

Yes, qtrl is designed to integrate into real-world workflows. It offers requirements management integration, supports connections to CI/CD pipelines for automated test execution as part of your build process, and provides APIs to work with your existing toolchain. It acts as a centralized QA layer that complements your current development ecosystem rather than forcing a complete replacement.

Is qtrl suitable for teams with no prior test automation experience?

Absolutely. qtrl's progressive approach is ideal for teams starting their automation journey. You can begin by using it purely as a test management tool. When ready, you can start with simple, English-language instructions for the AI to execute, which requires no coding. This allows teams to build automation expertise and trust in the platform gradually, at their own pace.

How does qtrl handle testing across different environments and with sensitive data?

qtrl provides robust multi-environment execution capabilities. You can define different environments (dev, staging, prod) with their own variables. Crucially, sensitive data like passwords or API keys can be stored as encrypted secrets that are injected at runtime. The AI agents never have direct access to these raw secrets, ensuring security and compliance when testing across various stages of your deployment pipeline.
