Is Mod compatible with React/Vue/Svelte?

Absolutely. Mod is intentionally built to be framework-agnostic. It provides pure, well-structured CSS and HTML blueprints for its 88+ components. This means you can effortlessly integrate Mod with any JavaScript framework like React, Vue, Svelte, or Angular, as well as with server-side frameworks like Ruby on Rails or Django. You simply apply Mod's CSS classes to your framework's components, giving you complete flexibility in your technology choices.

How does Mod handle customization and branding?

Mod is designed as a robust foundation for your unique brand identity. Its two core themes and 168 style utilities provide extensive control over colors, spacing, typography, and more through CSS custom properties (variables). You can easily override these variables to match your brand palette and design language. The component styles are built to be modular and adaptable, ensuring you can achieve a custom look while retaining all the responsive and functional benefits of the framework.

What is included in the yearly updates?

Your license includes access to all major and minor updates released within a yearly cycle. These updates are focused on value addition, not just maintenance. You can expect new components, enhancements to existing ones, new icon sets, theme improvements, advanced utility classes, and updates for accessibility standards and browser compatibility. This ensures your projects continuously benefit from the latest best practices in SaaS UI design.

Do I need design experience to use Mod effectively?

Not at all. Mod is built precisely for developers who want to ship exceptional UIs without being expert designers. The components are pre-designed with proven UX patterns, harmonious spacing, and balanced typography. By following the provided documentation and examples, you can assemble professional interfaces directly. It effectively acts as your design co-pilot, providing guardrails and high-quality defaults that allow you to focus on implementation logic.

How does qtrl.ai ensure control over the AI agents?

qtrl is built on a principle of "permissioned autonomy." You define the exact rules and boundaries within which the AI agents operate. Every action, from test generation to execution, is fully visible and reviewable in the platform. There are no hidden or black-box decisions; you maintain ultimate approval authority over what tests are created, what changes are made, and what gets executed, ensuring the AI earns trust through transparency.

Can qtrl.ai integrate with our existing development tools?

Yes, qtrl is designed for real-world workflows and offers built-in integration capabilities. It can connect with popular requirements management systems, version control, and CI/CD pipelines (like Jenkins, GitLab, GitHub Actions). This creates continuous quality feedback loops, allowing test execution to be triggered automatically by code commits or builds, and results to be fed back into your development process seamlessly.

What makes qtrl different from other "AI testing" tools?

Unlike tools that force a fully autonomous, AI-first approach which can feel risky and unpredictable, qtrl offers a progressive, trusted path. It combines robust test management with AI, allowing you to start simple and increase automation at your own pace. The focus is on augmenting human intelligence with AI assistance, not replacing it, and providing enterprise-grade governance that other tools lack.

Is my application data secure with qtrl's AI?

Absolutely. Security and data privacy are paramount. qtrl employs enterprise-ready security protocols. Crucially, for AI operations, your sensitive data like per-environment variables and encrypted secrets are never exposed to the AI agents. The system is designed to execute tests in defined environments without compromising sensitive information, ensuring your application data remains protected.
