CruxAI Site Builder
From idea to working app.
Tell CruxAI what you want to make. It can plan the project, build the interface, connect sign-in and saved data, test the result, and keep working with you until it is ready to publish.
Private draft first. You choose when to publish.
Work together without the busywork.
More than a page generator
A complete place to build and run.
Site Builder combines an AI collaborator with practical editors and managed app capabilities, so technical and nontechnical creators can work in the same project.
Build through conversation
CruxAI can discuss the idea first, ask useful questions, choose the right tools, and show live activity when work begins.
- Live plans and file activity
- Attachments from your device or Crux Cloud
- Continuation for larger builds
- Clear change summaries when work finishes
Edit without prompting
Use the visual editor to arrange pages and elements, or open the file editor for precise changes with syntax highlighting and version diffs.
- Drag-and-drop visual editing
- Responsive live preview
- File and folder explorer
- Undo, redo, download, and restore
Add real app behavior
Create saved information, member accounts, table relationships, forms, file uploads, and protected server actions without managing a separate backend.
- Managed app data and sign-in
- Forms and submission inboxes
- Cloud-backed site uploads
- Protected values for service credentials
See what changed
Every meaningful update can be reviewed before it reaches visitors. Compare versions, inspect the app console, and ask CruxAI to address an error in context.
- Version history and diffs
- Browser console capture
- Private owner-only preview
- Layout and quality checks
Ship on your schedule
Publish to a project address on cruxapps.io, then refresh, unpublish, or place the site into maintenance mode from the same workspace.
- Project-name.cruxapps.io hosting
- Publish and unpublish controls
- Maintenance mode
- Cache refresh controls
Bring your own domain
CruxAI+ projects can connect a domain they already own while retaining the CruxApps address, project tools, versions, and managed features.
- Guided DNS connection
- Automatic HTTPS provisioning
- Project-level usage insights
- Download individual files or the project
A deliberate workflow
Conversation when useful.
Action when ready.
Site Builder does not force every message into a build. CruxAI can help shape the idea, then use the appropriate tools once the direction is clear.
Describe
Start with a goal, a rough idea, an existing project, or files you want to use.
Build
Watch CruxAI create the actual files, data, and app behavior in a private draft.
Review
Use preview, visual editing, code, console messages, and version comparisons.
Publish
Choose when the project becomes public and keep improving it after launch.
Built for real applications
Front end, backend, and everything between.
A workspace people can understand
High-level labels make the experience approachable, while advanced tools remain available when the project needs them.
Private live previewOnly the project owner can see unpublished work.
Visual editorMove, add, and resize sections without writing code.
Flexible framework choicesCruxAI can select an appropriate verified approach for the project.
Managed services when needed
Sites can use PHP or Node.js server actions, managed MySQL data, authentication, forms, media, and protected integrations.
Managed app dataCreate tables, fields, records, and relationships per project.
Member accountsAdd registration and sign-in without inventing an auth system.
Cloud file uploadsRoute site-user uploads to managed object storage.
