Getting Started
Preview your application
A **preview** is the running application DeplAI started from a saved application version. Use it to click through the product the way a user would.
A preview is the running application DeplAI started from a saved application version. Use it to click through the product the way a user would.
Each preview is tied to a specific build and version. The code in Files for that version is the source for the application you are viewing.
When you can open it
A preview can become available once DeplAI can successfully run the application. You do not have to wait for every automated check before you look at it.
While DeplAI continues evaluating and improving the product, the preview may update as new versions are saved. If a later check fails, the build may move to Needs attention and the preview for that attempt may no longer be running.
Preview available versus Ready
| Status | Meaning |
|---|---|
| Building | DeplAI is still creating the application. |
| Starting preview | DeplAI is bringing the application up so you can use it. |
| Preview available | You can view and use the running application. |
| Checking application | DeplAI is exercising important workflows and presentation. |
| Improving application | DeplAI found a material issue and is updating the application. |
| Ready | Required application checks completed successfully for this version. |
| Needs attention | The build stopped or required checks did not pass. |
Preview available means the running application can be viewed and used.
Ready means DeplAI has also completed its required checks successfully. Ready is the point where Modify can start from that finished result.
You should still try the journeys that matter to you. Automated checks improve the result; they do not guarantee every possible path.
What you see in the preview
Preview applications often include demonstration data so you can browse realistic screens: sample products, customers, tasks, or appointments. That data is for preview and review. It is not production customer data. See Application data and demo content.
If the application includes sign-in, use the accounts or flows DeplAI provided in the preview so you can reach protected areas.
Preview labels in the inspector
The Preview panel reports whether the running application is healthy, still starting, stopped, or unavailable. If the running preview does not match the selected version, DeplAI will not show a mismatched application as if it were the version you selected.
Previews are temporary runtimes. Saved source is stored separately. After a temporary preview stops—for example after a failed check, a stop, or a workspace restart—you can still inspect Files and Download code for saved versions. Starting a new preview requires another build, retry, fix, or modify as appropriate.
