Start with the hosting your project uses
Current Bolt projects can use built-in hosting with a bolt.host address. An older project or an existing integration may use Netlify instead. Check the project itself before following an older tutorial or reconnecting a host.
Use the current publishing instructions for that setup and visit the public result separately from the editor preview. Record the URL, hosting account and version you released. Avoid changing providers simply because a guide assumes a different starting point.
Find the parts behind the screen
Ask the builder to map the main customer action: which code handles it, which service stores the result and which integration might incur a charge. If the interface currently displays sample arrays or browser-only state, publishing will not turn those into a shared database.
Check where private provider keys are used. An AI feature should not ship its paid credential inside browser JavaScript. Server endpoints also need permission and usage checks; otherwise visitors may be able to repeat expensive work without a meaningful limit.
Give the public version a small launch test
If you add a custom domain, repeat sign-in and callbacks there. A working temporary hostname does not prove every integration recognises the new address.
- Open it in a fresh browser, rather than relying on your existing editor session.
- Create an ordinary account and complete the main product task.
- Check that records remain after a refresh and cannot be accessed by another ordinary user.
- Verify production URLs and settings for email, payments and other connected services.
- Test a nested page opened directly, a failed request and an invalid form submission.
- Find a useful error log and note where you would make the next release.
Keep your next update predictable
Make small, reviewable changes and check the resulting published version. Keep a record of database changes separately from visual edits. A new screen can require a data migration, and reverting the screen does not undo that migration.
Before moving the project elsewhere, identify what you can export, where data will remain and which services need replacement. We can help assess that decision and document the setup so the app is understandable beyond the original building session.
A few fair questions.
Do I need Netlify to publish a Bolt app?
Not for every project. Bolt has built-in hosting. Existing Netlify-connected projects can have a different setup, so follow the path your project actually uses.
Does publishing make the database secure?
A public release does not prove that access rules match your product. Test permissions for signed-out visitors, normal users and admins against the connected database and backend.
Can you help without rebuilding the whole app?
We review what exists first. The goal is to fix the launch or operational gaps with an appropriate scope. A full rebuild is not an assumed starting point.
