Built with Databutton? Deploy it to Vercel.
Step-by-step deployment help for Databutton-built apps on Vercel. We fix deployment issues, configure Vercel correctly, and get your app live in production. From $19.
Databutton issues we fix before deploying
Problems specific to Databutton's code generation that affect Vercel deployments.
SQL injection in AI-generated query strings
Databutton's generated FastAPI endpoints sometimes build SQL queries using f-strings or string concatenation with user-supplied parameters, bypassing parameterized query protections entirely.
No authentication on data API endpoints
Data pipeline endpoints are frequently generated without authentication middleware, exposing raw database access and sensitive business metrics to anyone who discovers the API URL.
Unhandled data type mismatches crashing pipelines
Generated data processing code assumes clean input schemas. When upstream data contains nulls, type changes, or unexpected formats, pipelines throw unhandled exceptions and fail silently.
Missing pagination on large dataset queries
Data queries load entire tables into memory without limit or offset clauses. With more than a few thousand rows, responses time out and memory usage spikes.
Vercel deployment issues we check for
Common Vercel problems that break AI-generated apps in production.
Serverless function size exceeds 50MB limit
AI tools bundle heavy dependencies into API routes without tree-shaking, pushing serverless functions past Vercel's 50MB compressed size limit and failing the build.
Edge runtime incompatible with Node.js APIs
Generated code uses fs, crypto, or other Node.js built-ins inside Edge Runtime routes, causing deployment failures since Edge only supports a subset of Web APIs.
ISR revalidation not triggering correctly
Incremental Static Regeneration configured with stale revalidate values or missing on-demand revalidation hooks, serving outdated content indefinitely.
Environment variables missing in production
Secrets added to .env.local but not configured in the Vercel dashboard, causing runtime crashes only in production while working perfectly in local dev.

Frequently asked questions
Can you deploy a Databutton-built app to Vercel?
Yes. We regularly deploy Databutton-generated projects to Vercel. We handle the platform-specific configuration, fix deployment errors, and ensure your app runs reliably in production on Vercel.
What Vercel issues do Databutton projects typically have?
Databutton projects commonly have sql injection in ai-generated query strings and no authentication on data api endpoints. When deploying to Vercel, these combine with platform-specific issues like serverless function size exceeds 50mb limit and edge runtime incompatible with node.js apis.
How do I get my Databutton project live on Vercel?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Databutton-built projects targeting Vercel, the typical path is: fix Databutton-specific code issues, configure Vercel settings correctly, then deploy. We provide a fixed quote after the audit.
Can you handle the full deployment of my Databutton app to Vercel?
Yes. We handle end-to-end deployment: auditing your Databutton codebase, fixing deployment blockers, configuring Vercel correctly, setting up environment variables, and getting your app live in production. Start with our code audit ($19).
