Frequently Asked Questions
Quick answers to the most common questions about Vulcan.
General
Do I need to know how to code?
No. Vulcan is designed for non-engineers. You describe what you want in plain English, and the AI writes the code and deploys the app for you. If something doesn't look right, just say so in the chat and it fixes it.
Who can access my app?
Only Veho employees. Every app built on Vulcan is automatically protected — you need to be logged in with your Veho account to open any app. There's no way to make a Vulcan app publicly accessible, and no login screen to build.
Can multiple people use my app at the same time?
Yes. Multiple people can open and use your app simultaneously without any issues. Vulcan handles the scaling automatically.
Can multiple people edit the same app?
Not yet — only the project owner can make changes in the App Builder. You can share the live URL with your whole team, but editing is single-owner for now.
Is my data safe?
Your app's data is stored on Cloudflare's infrastructure inside Veho's account. It's not accessible to anyone outside Veho. That said, Vulcan is in Beta — see Limitations for the full picture on data guarantees.
Building
How do I share my app with the team?
Deploy to production (the Deploy to Production button in the toolbar), then share the production URL. Anyone at Veho with the link can open it. The preview URL also works for sharing a work-in-progress.
Can I connect my app to our internal data or systems?
Yes — ask the AI to call an internal API and describe the endpoint. The AI can wire up HTTP requests to any URL your app can reach. For pulling in data from AWS, Google Sheets, Airtable, Databricks, and other common services, check out the built-in integration components.
Can my app send emails?
Not with a built-in feature. For email, use a third-party service like Resend or SendGrid — the AI can wire these up via their REST APIs. You'll need to create an account with the service and add your API key as a secret in Vulcan.
For SMS, the Twilio component is available — but it is not plug-and-play. You must supply your own Twilio credentials (Account SID, Auth Token, and a Twilio phone number) and add them as secrets before it will work. → More details
Can my app show live updates without refreshing?
Persistent live connections (WebSockets) aren't supported. What does work: automatic polling (setInterval) and Server-Sent Events (SSE) for one-way push. Just ask the AI: "Refresh the table every 10 seconds." → More details
Can I build a multi-page app?
Yes — your app supports multiple views with client-side navigation (tabs, sidebars, route switching). Just describe it: "Add a navigation bar with Home, Reports, and Settings pages." See Multi-page apps.
Can I add charts, maps, or file uploads?
Yes — all of these are available as built-in UI components. Just ask the AI: "Add a bar chart showing monthly expenses" or "Let users upload a file." → UI Components
How do I let users log in or restrict access by role?
Every Vulcan app automatically knows who's logged in — you don't need to build a login screen. You can use the logged-in user's identity to restrict features: "Only users with the manager role can approve requests." → Users & Identity
Can I export data from my app?
Yes — the CSV Export component lets users download any table as a spreadsheet. Ask the AI: "Add a button to export this table as a CSV."
Limits & errors
How many apps can I have?
Up to 10 apps per user. If you need more, contact the platform team in #eng_product_platform_team.
My build failed — what do I do?
Check the Build Logs tab in the workspace panel. It shows the exact error. Copy it and tell the AI: "The build failed with this error: [paste it]." The AI will fix it. Your previous working version stays live while the error is sorted. → More details
The AI changed things I didn't ask it to change
Ask it to undo: "Undo that last change." Or be more specific next time: "Only change the button color — don't touch anything else." → More tips
I accidentally deleted data
Storage data isn't included in version snapshots, so restoring a version won't bring back deleted records. If the data is critical, contact the platform team in #eng_product_platform_team.
Still stuck?
Ask in #eng_product_platform_team on Slack — the team is happy to help.
You can also send feedback directly from inside Vulcan. Click the feedback button (speech bubble icon) in the Vulcan toolbar to submit a bug report, feature request, or general comment. It goes straight to the platform team — no need to leave the app.
