How to Deploy Your Base44-Built App

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.

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

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

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.

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.

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.

Deploying on a default subdomain like yourapp.vercel.app works for testing, but customers and investors notice. A custom domain costs $10-15/year and immediately makes your product look legitimate. Buy your domain from a registrar like Namecheap or Cloudflare, then point the DNS records to your hosting provider. Most platforms (Vercel, Netlify, Render) generate free SSL certificates automatically once your domain is connected - this gives you the HTTPS padlock in the browser. Without SSL, browsers warn users your site is "not secure," which kills trust instantly. Set up both the root domain (yourdomain.com) and the www subdomain, and configure one to redirect to the other so you don't split your traffic. If DNS propagation seems slow, give it up to 48 hours before troubleshooting. Once configured, verify your SSL certificate is valid by clicking the padlock icon in the browser address bar.

Manual deployments are error-prone and slow. Every modern hosting platform supports continuous deployment - connect your GitHub repo and every push to the main branch automatically triggers a new build and deploy. This means you can ship updates in minutes instead of hours. Set up branch-based preview deployments so every pull request gets its own temporary URL for testing before merging. This lets you (or your team) verify changes in a production-like environment without risking the live site. Configure your main branch as protected so code must pass tests before merging. For rollback strategy, keep it simple: if a deployment breaks something, most platforms let you instantly redeploy the previous working version from their dashboard. Vercel, Netlify, and Render all keep deployment history, so you're never more than one click away from reverting a bad deploy.

Deploying is not the finish line - it's the starting line. In the first week after launch, things will break in ways they never did locally. Set up uptime monitoring with a service like UptimeRobot or Better Stack (both have free tiers) to alert you within minutes if your site goes down. Install Sentry for error tracking - it captures every unhandled exception in production with full stack traces, so you can fix bugs before users report them. Watch your hosting platform's metrics dashboard for CPU spikes, memory usage, and response times. If your Base44 app uses a database, monitor query times and connection counts. Set up alerts for the things that matter most: site down, error rate above 1%, and response time above 3 seconds. In the first week, check these dashboards daily. After that, let the alerts do their job and check weekly.
