Application Quality

DeplAI combines automated evaluation with self-healing repairs to deliver working, usable applications. Rather than just verifying that code compiles, DeplAI exercises the running application to check real product behaviors.

Automatic workflow checks

When you describe an application, DeplAI identifies the key actions a user needs to perform. Once the preview starts, DeplAI tests those essential journeys directly against the running product.

Typical workflow checks include:

• Authentication and account access: Can users sign in, view role-protected screens, and sign out?
• Data creation and persistence: Can a user create an item (like adding a task, scheduling an appointment, or placing an order) and see it reflected immediately on the screen?
• Form submission and validation: Do input forms accept valid information, handle required fields, and provide appropriate confirmation?
• Navigation and routing: Do navigation links, buttons, and menus direct users to the correct screens without dead ends or blank views?

If a required journey fails during verification, DeplAI flags the issue for automatic repair. If it cannot be resolved automatically, the build moves to Needs attention with the specific failing check recorded in the Checks panel.

Desktop and mobile review

Modern applications must look and feel great on any screen size. DeplAI reviews how screens render across both desktop and mobile viewports:

• Responsive layouts: Do grids, columns, and cards reflow cleanly on mobile screens?
• Touch and navigation usability: Are navigation bars, menus, and buttons easily accessible and appropriately sized on mobile devices?
• Visual hierarchy and readability: Are typography, contrast, and spacing well balanced so content is readable and pleasant to browse?
• Media and asset display: Do images and UI icons load properly without broken links or overflow?

When a screen exhibits obvious visual breakage—such as clipped content, overlapping text, or broken navigation menus—DeplAI flags it as a material layout problem for automatic improvement.

Automatic improvements

DeplAI does not stop after generating an initial codebase. When workflow checks or visual reviews detect a material issue, DeplAI's self-healing build process intervenes:

1. 1Diagnose the issue: DeplAI analyzes the failed journey or layout defect.
2. 2Apply targeted updates: The relevant source files are updated to resolve the problem.
3. 3Save a new version: The updated codebase is preserved as a new application version in history.
4. 4Re-evaluate the preview: DeplAI restarts the preview from the updated version and re-runs the checks to confirm the fix.

This loop continues until the required checks pass or the allotted improvement cycle completes. See Automatic application improvement for full details.

Understanding Ready status

The build lifecycle distinguishes between when you can start exploring and when DeplAI considers its automated validation complete:

Ready is the foundation for changes

Reaching Ready marks the point where your application has a verified, stable foundation. From here, you can:

• Use Modify to add features or request design changes in natural language.
• Open Files to inspect the clean generated source code.
• Click Download code to export your application codebase.

Human review remains essential

While DeplAI automatically checks important workflows and repairs issues it detects, it does not guarantee bug-free applications or replace human judgment. Automated evaluation focuses on core requirements and common failure modes.

Before launching an application in production, you should always conduct your own review of business-critical edge cases, sensitive business rules, and specific organizational requirements.
