Publish App

Go Live

Once you've previewed your application and everything looks correct, it's time to publish. Publishing makes your app accessible at its public URL: yourapp.obto.co.

How Publishing Works

OBTO applications are live the moment their artifacts are deployed. There is no separate "build" or "release" step. When the AI writes code using obto_upsert_record or obto_create_route, that code is immediately available on the platform.

What "publishing" means on OBTO:

• Your application's pltf_page records are served when someone visits the host URL

• Your API routes are active and callable

• Your server scripts are running and available via xe.

If you've deployed all artifacts and the host is set correctly, your app is already live.

Your App URL

Every OBTO application gets a URL based on its host configuration:

https://{appName}.obto.co

The host field on your browser-facing artifacts (pltf_page, pltf_javascript, pltf_stylesheet) determines which URL serves them. All artifacts that belong to the same website must share the same host value.

Publishing Checklist

Before sharing your app URL, verify:

Check	How
✅ All server scripts deployed	AI used obto_upsert_record with pltf_script_server
✅ All routes deployed	AI used obto_create_route
✅ All stylesheets deployed	AI used obto_upsert_record with pltf_stylesheet
✅ All JavaScript modules deployed	AI used obto_upsert_record with pltf_javascript
✅ All pages deployed	AI used obto_upsert_record with pltf_page
✅ Host values are consistent	All browser-facing artifacts use the same host
✅ Preview looks correct	Generated and checked via obto_generate_preview

Deployment Order Matters

If your app has both frontend and backend, always ensure the AI deployed in the correct order:

1. pltf_script_server  →  Backend logic first
2. pltf_route           →  API endpoints second
3. pltf_stylesheet      →  CSS styles
4. pltf_javascript      →  React frontend modules
5. pltf_page            →  HTML entry points last

If the AI deployed out of order, your page may fail to load. Ask the AI to redeploy the page:

"Redeploy the index page for my-app"

Updating a Published App

Published apps are updated in real-time. When the AI modifies any artifact:

• Changes are immediate — No build step, no deploy pipeline, no CI/CD

• No downtime — The platform hot-swaps the updated artifact

• Rollback — The AI can fetch the current version, restore it, and redeploy

To update, just continue the conversation:

"Change the hero section background to dark purple"
"Add a new /pricing page"
"Fix the contact form — it's not saving submissions"

Custom Domains

By default, your app is served at yourapp.obto.co. Custom domain configuration is available for production deployments. Contact [email protected] for custom domain setup.
