FAQ
Can you fix my Base44 app without rebuilding everything?
Yes. I can review your existing Base44 app, identify the cause of the issue, and recommend targeted repairs. If rebuilding part of the app is necessary, I will explain why before we agree on the scope.
Can you fix broken buttons, blank pages and features that stopped working?
Yes. My Base44 bug fixing service covers broken buttons, blank screens, form errors and workflows that fail to complete. Send screenshots, any error messages and the steps that trigger the problem so I can investigate.
Can you fix login, signup and database issues?
Yes. I can troubleshoot authentication, user permissions, missing records and data that will not save or display. For Base44 debugging, I check the affected workflow and its database connections to locate the underlying issue.
Can you fix Stripe payments and subscription problems?
Yes. I can troubleshoot Stripe integration, failed checkout, subscription updates and webhook issues. Tell me what should happen after payment and what currently happens so I can assess the required fix.
Can you connect my Base44 app to an API or another tool?
Yes. I offer Base44 integration and API integration for supported third-party services. Share the service name, its API documentation and the workflow you want to automate so I can confirm compatibility and scope.
Can you finish an app built with AI or vibe coding?
Yes. I can review an unfinished Base44 web app, repair broken functionality and help complete agreed features. My vibe coding cleanup focuses on making your existing app work reliably for the tasks your users need.
Can you help deploy my Base44 app or fix launch errors?
Yes. I provide Base44 deployment support and troubleshoot issues preventing your app from going live. Share your target platform, domain and any deployment errors so I can confirm the steps and access required.
Can you migrate my Base44 app to WordPress or another platform?
Yes. I can assess Base44 migration, including Base44 to WordPress projects. Features, data and integrations may need rebuilding on the destination platform, so I will explain what can transfer and what requires additional work.
