Built with Databutton? Deploy it to Heroku.
Step-by-step deployment help for Databutton-built apps on Heroku. We fix deployment issues, configure Heroku 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 Heroku 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.
Heroku deployment issues we check for
Common Heroku problems that break AI-generated apps in production.
Free dyno sleeping causes cold starts
Eco and Basic dynos sleep after 30 minutes of inactivity. AI-generated apps with webhook receivers or background jobs break when the dyno is asleep.
Ephemeral filesystem loses uploaded files
AI tools save user uploads and generated files to the local filesystem, but Heroku's ephemeral FS wipes all changes on every dyno restart or deploy.
Database connection pool exhaustion
Heroku Postgres plans have strict connection limits (20 on Hobby). AI-generated apps open a new connection per request, exhausting the pool under moderate traffic.
Procfile missing or incorrect
AI-generated projects lack a Procfile, causing Heroku to guess the start command. For non-standard setups, this guess is often wrong.

Frequently asked questions
Can you deploy a Databutton-built app to Heroku?
Yes. We regularly deploy Databutton-generated projects to Heroku. We handle the platform-specific configuration, fix deployment errors, and ensure your app runs reliably in production on Heroku.
What Heroku 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 Heroku, these combine with platform-specific issues like free dyno sleeping causes cold starts and ephemeral filesystem loses uploaded files.
How do I get my Databutton project live on Heroku?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Databutton-built projects targeting Heroku, the typical path is: fix Databutton-specific code issues, configure Heroku settings correctly, then deploy. We provide a fixed quote after the audit.
Can you handle the full deployment of my Databutton app to Heroku?
Yes. We handle end-to-end deployment: auditing your Databutton codebase, fixing deployment blockers, configuring Heroku correctly, setting up environment variables, and getting your app live in production. Start with our code audit ($19).
