Taking control of your digital life by running a self hosted web app is an empowering journey. Instead of relying on third party platforms, you host applications on your own server, giving you complete ownership over your data, features, and costs. This guide will walk you through everything you need to know, from picking the right hardware to deploying and maintaining your favorite services. For step-by-step tutorials and videos, see WeWeb Academy.
The goal is to demystify the process, making it accessible even if you’re not a seasoned system administrator. Agencies that need to ship client projects fast can use WeWeb for agencies to speed up delivery while keeping full control. It’s about building your own corner of the internet. For many, this starts with the application itself. Platforms like WeWeb offer a visual development environment to build your app without code, and then you can export the code to self host it, giving you the best of both worlds: fast development and full control.
Before you can run any software, you need a place for it to live. This section covers the foundational hardware and architectural decisions for your self hosted web app.
Choosing the right hardware is about matching the server’s capabilities to your application’s needs. You need to balance performance and cost.
Compute (CPU): A simple static website needs very little processing power, while a video transcoding server like Jellyfin benefits from a powerful multi core CPU.
Memory (RAM): RAM is critical for performance. Databases and applications that use caching need plenty of it to avoid slowing down.
Storage: The type of storage you choose has a huge impact. For databases or other tasks with heavy reading and writing, NVMe SSDs are a game changer, offering up to five to ten times the throughput of SATA SSDs. For bulk file storage, traditional HDDs offer more space for your money.
Network: A fast and reliable network connection is crucial, especially if you plan to serve large files or stream media.
Once you know your required specifications, you need to decide where your server will live.
VPS (Virtual Private Server): A VPS is a virtual machine running on shared physical hardware. It’s a flexible and affordable way to start, offering a good balance of performance and cost for most projects. You get a slice of the server’s resources for your own use.
Dedicated Server: This is a physical server that you rent all to yourself. It provides maximum performance and is ideal for very demanding applications, but it comes at a higher cost and requires more management.
A recent trend shows that many organizations are bringing workloads back from the public cloud to private infrastructure, with one report indicating that 86% of IT leaders have plans for repatriation to gain more control and manage costs.
How you structure your services is your hosting architecture.
For beginners, a single host deployment is the most common starting point for a self hosted web app. This means your application, your database, and any other services all run on a single VPS or dedicated server. It’s simple to manage and cost effective.
Low Resource Footprint: Choose software that uses minimal CPU, memory, and disk space. Lightweight applications allow you to run more services on the same hardware, which is especially important on a small VPS.
Minimal Dependency: Software with fewer external requirements is easier to install, maintain, and secure. An application that is just a single file is much simpler to manage than one that needs a specific web server, a database, and numerous libraries to be installed first.
With your hardware ready, it’s time to install the software that will power your self hosted web app. Modern hosting relies on a few key technologies.
Docker is a technology that packages an application and all its dependencies into a standardized unit called a container. This solves the classic “it works on my machine” problem by ensuring your application runs the same way everywhere. Containers are lightweight and isolated, so you can run multiple applications on the same server without them interfering with each other. Container adoption has become widespread, with over 92% of IT organizations using them.
A related concept is DockPeek, which refers to the idea of “peeking” inside a Docker container to inspect its files, logs, and processes for easier debugging. While not a specific tool, it highlights the need for visibility into your containerized applications.
A reverse proxy is a server that sits in front of your web applications and forwards client requests to them. Nginx is a popular, high performance choice. It can route traffic to different Docker containers based on the domain name, allowing you to host multiple websites on a single IP address. It also handles SSL/TLS termination, providing HTTPS for your services.
To make your website as fast as possible, you should use modern web standards.
HTTP/3: The latest version of the HTTP protocol, which uses QUIC to reduce latency and improve performance, especially on poor networks.
Brotli: A compression algorithm that makes your website files smaller. Brotli can often compress text based files like HTML and CSS about 15% to 25% smaller than the older gzip algorithm, leading to faster downloads for your users.
The Domain Name System (DNS) is what translates human friendly domain names (like example.com) into IP addresses that computers understand. Managing your DNS involves setting up records that point your domain to your server’s IP address. This is a critical step to make your self hosted web app accessible to the world.
A CDN is a network of servers distributed around the globe that cache your website’s static content, like images and scripts. When a user visits your site, the content is delivered from the server closest to them, dramatically reducing load times. Many modern web applications, like those built with WeWeb’s visual UI builder, can be deployed on a global CDN with a single click.
Most dynamic web applications need a database to store information like user accounts, posts, or product information. If your backend exposes GraphQL, you can connect it directly to your front end via WeWeb’s GraphQL integration. You can self host your database on the same server as your application or on a dedicated server for better performance and security. Popular open source choices include PostgreSQL and MariaDB.
Deploying your application and automating tasks are key to an efficient workflow. This is where you move from setup to ongoing management.
A static site is composed of pre built HTML, CSS, and JavaScript files. Deploying one is incredibly simple, often just a matter of copying the files to your web server. This approach is very secure and requires minimal server resources, making it perfect for blogs, portfolios, and marketing sites.
When you update your application, you don’t want to take it offline. Zero downtime deployment is a strategy where you start the new version of your application, switch traffic over to it seamlessly, and only then stop the old version. This ensures your users are never interrupted.
The Command Line Interface (CLI) and Secure Shell (SSH) are the foundational tools for server automation. Instead of manually logging in to a server to perform tasks, you can write scripts that use SSH to connect and run commands automatically. This is essential for consistent and repeatable deployments.
Continuous Integration (CI) is the practice of automatically building and testing your code every time a change is made. Integrating a CI pipeline, using tools like GitLab CI or GitHub Actions, into your workflow ensures that every code change is validated before it gets deployed, leading to more reliable software.
A process supervisor is a tool that ensures your application is always running. If your app crashes for any reason, a supervisor like systemd will automatically restart it. This is a simple but powerful way to improve the reliability of your self hosted web app.
A self hosted PaaS provides a Heroku like deployment experience on your own server. You simply push your code, and the platform handles building, deploying, and managing your application in containers. This abstracts away much of the complexity of server management.
Dokku: Often called a “mini Heroku in a box”, Dokku is a lightweight PaaS built on Docker that lets you deploy apps with a simple git push.
CapRover: An easy to use PaaS with a friendly web interface and a one click app store for deploying common applications like WordPress or databases.
Coolify: An open source, self hostable PaaS that aims to make deploying applications on your own server simple and approachable.
Kamal: A deployment tool from the creators of Ruby on Rails that deploys web applications to any server using Docker, with a focus on zero downtime deployments and easy rollbacks.
K3s: A lightweight, certified Kubernetes distribution. It gives you the power of Kubernetes orchestration without the heavy resource requirements, making it perfect for edge computing or home labs.
Portainer is a popular web based UI that helps you manage your Docker environments. It provides a visual interface for deploying and managing containers, images, and networks, making Docker much more accessible for those who are less comfortable with the command line.
Once your self hosted web app is running, the job isn’t over. You need to keep it secure, backed up, and running smoothly.
You can’t manage what you don’t measure. Monitoring your self hosted web app involves tracking your server’s health and performance, including CPU usage, memory, and network traffic. Tools like Prometheus and Grafana can be used to collect metrics and create dashboards, giving you a complete view of your system’s state.
Instead of sending your visitor data to Google, you can use a self hosted analytics platform like Matomo or Plausible. This gives you valuable insights into your website’s traffic while respecting the privacy of your users.
When something goes wrong in your application, you need to know about it immediately. Error reporting tools like Sentry (which can be self hosted) capture exceptions in your code and alert you, providing detailed information to help you debug the problem quickly. Elite DevOps teams who use such practices can recover from failures over 2,600 times faster than low performing teams.
Securing your server is non negotiable. Key practices include:
Firewall: Use a firewall like UFW (Uncomplicated Firewall) to control what traffic is allowed to reach your server.
Regular Updates: Keep your server’s operating system and all installed software up to date to patch security vulnerabilities.
SSH Keys: Use SSH keys instead of passwords for a more secure way to log in to your server.
Fail2Ban: Install software that automatically blocks IP addresses that show malicious signs, such as too many failed login attempts.
Bot protection: Add Google reCAPTCHA to public forms to reduce spam and scripted abuse.
Data loss can be catastrophic. A solid backup and disaster recovery plan is essential. This involves regularly creating copies of your data and storing them in a separate location, ideally offsite. The “3 2 1” rule is a good guideline: keep at least three copies of your data, on two different types of media, with at least one copy offsite.
So what can you actually run? Here are some of the most popular open source applications people self host.
Nextcloud is a full featured content collaboration platform, offering a suite of tools that function as your own private cloud. It’s a powerful alternative to services like Google Drive or Dropbox, allowing you to sync and share files, manage calendars and contacts, edit documents, and even have video calls, all from a server you control.
Home Assistant is a powerful open source home automation hub. It integrates with thousands of smart devices and services, allowing you to create complex automations and control your entire smart home from a single, private interface that runs locally.
Jellyfin is a free software media system that lets you manage and stream your movies, TV shows, music, and photos. You can install it on your server and access your entire media library from any device, anywhere in the world, creating your own personal Netflix.
If you have a large music collection, Navidrome lets you create your own personal streaming service. It’s a lightweight, modern music server that is compatible with a wide range of mobile apps, so you can listen to your tunes wherever you are.
As an alternative to Google Photos or iCloud, Immich is a high performance self hosted photo and video backup solution. It comes with mobile apps that automatically upload your media, allowing you to keep your memories safe on your own server.
Paperless NGX transforms your physical documents into a searchable digital archive. You can scan your bills, receipts, and letters, and it will use OCR to make the text searchable, then organizes everything with tags and correspondents for easy retrieval.
Building the application is the first step, and with a platform like WeWeb, you can visually craft the exact professional tool you need—or start from production-ready WeWeb templates to accelerate setup. Once it’s built, the self hosting journey described here gives you the power to run it with complete freedom.
