Fix a broken Base44 app
Updated
Short answer
A Base44 app is built with Base44's own data tables, user management and hosting. That means launch problems can involve data permissions, sign-in settings, emails, your domain and the last publish. Check those in Base44 first, then open the live app in a private window. If it is still broken, a free VibeFix check tries the problem on your live app, and the fix in the code is $79, paid up front.
This page is about apps built with Base44. The name is used only to say which tool this is about.
How a Base44 app breaks once real users arrive
Base44's docs describe it as an app builder that includes "design, databases, user management, and hosting." The problems below follow from those built-in settings.
- Data not saving, or visible to the wrong people. Base44 says each table "has its own permissions page, listing the rules that decide who can create, read, update, and delete its records." Wrong rules can block saves or show too much. We have no separate VibeFix guide for Base44 permissions; the general guide is Base44 app not working? Causes and fixes.
- Google sign-in fails for new people. See Base44 Google sign-in "origin_mismatch": the fix.
- Your own domain will not connect. See Base44 custom domain not working: pending verification.
- Emails not arriving. Base44 says that for people who have not signed up, "Your app needs a paid plan and a custom domain connected and verified", and that an unsent email "appears in your app logs with the reason." Check the logs before assuming the email service is at fault.
- Blank page, or changes not live. Base44 says that after you redeploy a backend function, your live app "keeps running the version from your last publish until you publish again." See Blank page after publish and Works in the preview but not after publishing.
- Payments. Base44 documents Stripe, PayPal and Base44 Payments. If customers cannot pay on the live app, see Customers can't pay and Stripe checkout not working on the live site.
What you can try yourself first
- Ask Base44's chat. Its troubleshooting page says: "type 'Something is wrong' in the AI chat."
- Check the Base44 status page. The same page links to status.base44.com for system-wide problems.
- Review data permissions and run a security scan. Base44's security overview says to "always review your permissions and run a security scan before you publish." On each table you can use Test permissions in preview.
- Publish again and test the live address.
- Check app logs for emails that did not send.
- Test as a stranger: a private window and a new email address.
How VibeFix helps
VibeFix is independent of any app builder. Our AI agent can fix a Base44 app in its code when the code is on GitHub. Base44 says it supports "a GitHub based workflow" for your app code, and that connecting needs a Builder plan or higher (Base44 docs on GitHub).
- Free check. "You tell us what broke. Our AI agent tries it on your live app, says whether it hit the same problem, and sends a screenshot."
- Fix. "Our AI agent finds the cause and fixes it in your code." The price is "$79, paid up front."
- Delivery and re-check. "A GitHub pull request in your own repository." After the fix is live, the AI agent goes back to your live app and repeats the check that failed, the way a customer would.
- Refund. "If we can't complete your re-check, you get your money back."
- Which apps. "Today the fix is for apps built with Lovable, or any app whose code is on GitHub."
- Never asked. "We never ask for passwords."
A check reports what the AI agent saw. It does not promise that every problem is found.
