How to Deploy Your Base44-Built App
Step-by-step guide to deploying your Base44 app to production. Covers React frontend with a Node.js backend and PostgreSQL database. Base44 is a no-code AI builder that generates full-stack applications with a built-in data model deployment, environment variables, and production configuration.
What Base44 generates
Base44 typically generates projects using React frontend with a Node.js backend and PostgreSQL database. Base44 is a no-code AI builder that generates full-stack applications with a built-in data model, auth, and deployment within its platform. Understanding the stack is important because it determines your deployment options and the specific configuration you'll need.
Where to deploy
Base44 provides managed hosting within its platform. For teams that need to self-host, the generated application can be exported as a Node.js and React project deployable to Railway, Render, or any Node-compatible platform
Step-by-step deployment
If staying on Base44's platform, deployment is managed. For self-hosting: export the project, set up a PostgreSQL database with the generated schema, configure environment variables (database URL, auth secrets, API keys), build the React frontend, and deploy backend and frontend together or separately. Set up backups for the PostgreSQL database before going live
Environment variables
One of the most common deployment failures is missing or misconfigured environment variables. Base44 apps often hardcode values during development that need to be externalized for production. Audit every file for hardcoded URLs, API keys, and configuration values. Create a .env.example file listing every required variable. Set these in your hosting platform's dashboard before deploying.
Post-deployment checklist
After deploying, verify: HTTPS is enforced on all routes, custom domain is configured and resolving, environment variables are correctly loaded, all features work in production (not just locally), error tracking is capturing exceptions, and performance is acceptable under real conditions.
Common deployment mistakes
The most frequent issues we see in Base44 deployments: forgetting to set environment variables (causing startup crashes), not testing the production build locally before deploying, missing build dependencies, and using development configurations in production.
