Looking for Free Hosting Options for a Full MERN Stack App #175658
|
Hi Developers, I'm working on a personal project using the MERN stack (MongoDB, Express, React, Node.js), and I'm looking for free hosting platforms that can support the full stack — both the frontend (React) and the backend (Node.js/Express), along with a connection to a MongoDB database. I know GitHub Pages is great for static frontend apps, but since my project has a dynamic backend and a database, I need a more complete solution. I’ve looked into platforms like: Render Vercel Railway Replit Glitch Some of them seem promising, but I’m not sure which ones: Offer a free tier with sufficient resources for a small personal app Allow both backend and frontend deployment Support connecting to MongoDB (hosted or remote like Atlas) Does anyone have experience hosting a full MERN app for free? Thanks in advance! |

You can host the frontend (React app) for free on Vercel – Excellent for React; auto-deploys from GitHub. Great developer experience. Both platforms are static site hosts but perfect for React SPAs built with create-react-app, Vite, etc. Backend (Express + Node.js) Render Free tier available (Web Services). You need to manage usage carefully to stay within the free limit. Replit Good for small apps and experiments. In-browser IDE with built-in hosting. Not ideal for production-level apps (resource limits). Glitch Quick setup for Express apps. Has usage caps and will put apps to sleep, so use for prototyping only. Database (MongoDB) MongoDB Atlas is the go-to free-tier option: Free cluster (M0 tier) with 512MB storage. Can be hosted in various cloud regions. Secure, allows IP whitelisting and connection strings. Use it with Render, Railway, or any of the above platforms. Recommended Setup for a Free MERN App Frontend: Vercel or Netlify (React app) Backend: Render (Node.js/Express) Database: MongoDB Atlas (free tier) You can deploy them separately and make the frontend call the backend via API |

Hello. Good morning @awais4212, thank you for this answer. Please, I'm new to this so can you tell me how I can deploy these services separately - the Frontend and Backend, and use APIs to call Backend? |
|
Hey! Sure. I usually deploy the React frontend on Vercel and the Node/Express backend on Render. After deploying the backend, Render provides a public URL. I simply use that URL in the frontend with fetch or axios to make API requests. Once it's set up, the frontend and backend communicate without any issues. If you need help with the deployment process, feel free to ask. |

Yo! @awais4212 thanks for this. I tried it this evening and it worked smoothly. It did crash a few times at first, but after some re-configurations, it popped up. |

I'm glad to hear it @draco-mordred |

When it comes to free hosting for a full MERN stack app, there are some solid options like Render, Vercel, Netlify (for the frontend), and MongoDB Atlas (for the database). These platforms offer generous free tiers that are great for testing and small projects. However, if you’re planning something more scalable, you may eventually need to shift to paid plans for better performance and reliability. Tools like Delta can also play a role in streamlining deployment and integrations, making the overall hosting and management process much smoother. |

I Recommend setup for a Free MERN Application |

Vercel is good |

From real deployment experience, yes, you can host a full MERN stack for free, but the setup must be intentional. Recommended Free MERN Hosting StackFrontend (React)Vercel or Netlify Backend (Node.js / Express)RenderThe most stable free option for running a full Express server. Supports MongoDB connections, environment variables, logs, and GitHub integration. Free services sleep after inactivity, which causes cold starts. RailwayVery easy to deploy, but the free tier is limited by usage credits and is less predictable for long-term free hosting. DatabaseMongoDB Atlas (M0 free tier) Best Practice ArchitectureHost frontend and backend separately Use environment variables for API URLs and secrets Expect cold starts on free backend tiers Plan an upgrade path early if the app gains users Final RecommendationFor personal projects, demos, and MVPs: Frontend: Vercel or Netlify Backend: Render Database: MongoDB Atlas This setup is production-aligned, easy to maintain, and the most reliable free MERN stack currently available. |

You can host the frontend (React app) for free on
Vercel – Excellent for React; auto-deploys from GitHub. Great developer experience.
Netlify – Also React-friendly with continuous deployment and free custom domains.
Both platforms are static site hosts but perfect for React SPAs built with create-react-app, Vite, etc.
Backend (Express + Node.js)
To host your backend server for free:
Render
Free tier available (Web Services).
Can deploy Express apps.
Includes a free tier with auto-sleep (cold starts after inactivity).
Can connect to external services like MongoDB Atlas.
Railway
Super simple to deploy Node.js/Express apps.
You need to manage usage carefully to stay within the free limit.
