How to Deploy Your Devin-Built App

Devin typically generates projects using Varies — Devin operates autonomously and may choose any stack. Common outputs include Python with Django/Flask/FastAPI, Node.js with Express, and React frontends. Understanding the stack is important because it determines your deployment options and the specific configuration you'll need.

Depends on what Devin built. The challenge is understanding Devin's choices — it may have chosen an unusual architecture or dependency combination that affects deployment options

First: understand what Devin built. Review the entire project structure, dependencies, and architectural decisions. Identify any implicit requirements (databases, external services, background workers). Document the deployment requirements. Then set up hosting, environment, and CI/CD accordingly

One of the most common deployment failures is missing or misconfigured environment variables. Devin 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 Devin 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.
